some great science (see Science Highlights on pages 10-13) and recruited some great young scientists, all the while preparing for our move to the Francis Crick Institute (see pages 6-7). New staff Kathy Niakan started her career with Edward McCabe at UCLA and Kevin Eggan at Harvard, and then moved to Cambridge to investigate the molecular basis of early cell fate decisions in humans and mice. At NIMR she is exploring the regulation of embryonic stem cell pluripotency. Vivian Li did her PhD at the University of Hong Kong and then moved to the Hubrecht Institute in Utrecht to work with Hans Clevers on Wnt signalling in intestinal stem cells. She continues this line of research at NIMR by studying Wnt pathway regulation in the intestine and in mouse models of human colorectal cancer. Mariia Yuneva was awarded her PhD in Alexander Boldyrev’s lab at Moscow State University and then moved to the Cold Spring Harbor Laboratory to study the nutrient dependence of oncogene-transformed cells with Yuri Lazebnik. Having worked with J. Michael Bishop at UCSF, studying mouse models of cancer, she moved to Mill Hill to study the relationship between oncogenes and tumour metabolism. Markus Ralser worked in Salzburg, Amsterdam, and the Max Planck Institute for Molecular Genetics in Berlin before establishing his own group at the MPI-MG working on the molecular biology of metabolism. Before coming to NIMR he worked at the University of Cambridge, where he developed his interests in the regulatory and dynamic functions of the metabolic network. Sila Ultanir worked on neuronal development and synaptogenesis in Rafael Yuste’s lab at Columbia University before moving to Anirvan Ghosh’s lab at UCSD. Moving to Yuh-Nung Jan’s lab at UCSF she studied signalling mechanisms and dendrite development using chemical genetics, and at NIMR she will look at pathways that regulate the formation and plasticity of dendrite arbors and dendritic spines. Finally, Andreas Schaefer worked with Bert Sakmann and Hermann Bujard at the Max Planck Institute for Medical Research in Heidelberg, and then moved to UCL to work with Troy Margrie. He moved back to MPI-MR as a group leader, before coming to NIMR to explore, using the mouse olfactory system, how complex behaviour emerges from the properties of molecules, cells and ensembles of cells. (top row) Kathy Niakan, Vivian Li, Mariia Yuneva (bottom row) Markus Ralser, Sila Ultanir and Andreas Schaefer New facilities Since our quinquennial review we have established several new areas of research at NIMR, and we have set up a number of Institute-wide technology platforms to make the associated methodologies available to as many of our researchers as possible. The human embryonic stem cell facility will allow researchers from many disciplines to exploit this exciting and versatile technology; the new metabolomics platform will support researchers such as Alex Gould, Dimitris Anastasiou, Mariia Yuneva and Markus Ralser, and it will open the door for many others to contribute to this burgeoning field; and our Biological Computing technology platform will allow all NIMR researchers to make the most of our excellent high-throughput sequencing facility. Together, these facilities will make a huge difference to the science done at the Institute, and they will go a long way to encouraging further multi-disciplinary research. 4 MRC National Institute for Medical Research Recognition and grants awarded We were very pleased that Gitta Stockinger and Jean-Paul Vincent were both elected to the Fellowship of the Royal Society this year. More good news followed as we heard that Iris Salecker was elected as an EMBO member and Alex Gould was elected to the Academy of Medical Sciences. Pavel Tolar is now an EMBO Young Investigator and Annalisa Pastore was elected to the Academia Europaea. Tim Bliss, formerly head of the Division of Neurophysiology, was one of the recipients of the 2013 Fondation Ipsen Prize for Neuronal Plasticity, and earlier in the year Gitta Stockinger was named as the recipient of the 2014 Feldberg Foundation Prize. I was pleased to be awarded the Waddington Medal of the British Society for Developmental Biology. Major new funding awards this year included a Wellcome Trust Senior Investigator award for Gitta Stockinger, and a large share of a Wellcome Trust Strategic Award awarded to Tim Mohun and me, to identify genes essential for mouse development and the origins of developmental diseases and birth defects in humans. A European training grant for Developmental and Computational Biology is shared between Mike Gilchrist’s and my own research group. Anne O’Garra and Iris Salecker led a team that put together an application for an Athena SWAN award, participating in a pilot scheme in which research institutes such as NIMR could apply for the first time. The award helps ensure that women are properly represented at all levels in the Institute’s work, and we were very pleased to hear, at the end of last year, that we achieved the equivalent of a bronze award. Throughout the year the Medical Research Council has celebrated its centenary. We were pleased to welcome Sir John Savill, MRC Chief Executive, who talked to staff about the history of the MRC and the part that NIMR, the first MRC institute, has played in that history. Another talk was given by Harriet Tuckey, about her father Griff Pugh. He was the NIMR physiologist who advised the 1953 Everest expedition and Harriet’s biography of him was published this year. You can read more about the ways that NIMR celebrated the MRC centenary on pages 32-34. . Several members of staff left during 2013. They include Tom Carter, John Doorbar, Richard Goldstein, Malcolm Logan, Elke Ober, Annalisa Pastore, Andres Ramos and Ben Seddon. I thank them all for their wonderful contributions to NIMR over many years, and wish them well in their new positions. Another leaver was Paul Burgoyne, who retired after more than 20 years at NIMR. A symposium was held in January to mark his contribution to our knowledge of sex chromosomes, infertility and germ line development. Several long-serving research support staff also left. These include John Wills (45 years), Bill Jarra (43 years), Surendra Kotecha (38 years), John McCormick (36 years), Malcolm Strath (30 years), Barry Ely (32 years) and Treena Carter (26 years). And finally we were very sorry to learn of the deaths of three former NIMR group leaders: James Lightbown, John Cornforth and Michael Sargent. Tributes to them have appeared on our web site and are reprinted on pages 136-138. Ita Askonas died on 9 Jan 2013 and a tribute to her appeared in last year’s Annual Report. A symposium in her memory will take place in April 2014. All three scientists made very important contributions to NIMR and will be greatly missed. We were also sad to hear of the deaths of Arthur Rogers (Mechanical Engineering) Gordon Bissett (Neurophysiology), Alan Brownstone (Chemistry), Betty Higginson (Biochemistry) and Derek Rumley (Engineering). MRC National Institute for Medical Research 5 The Francis Crick Institute This year has seen the Francis Crick Institute really start to take shape, both with respect to people and with respect to our new building. The Crick’s offices at the Wellcome Trust’s Gibbs Building are becoming ever more crowded as new staff join the project. Alison Davis has been appointed as head of IT; Nick Carter as Director of Building Services; Michael Schuitevoerder as Transition Director; and John Macey as Head of Human Resources. Their teams have been augmented by many people from the two founding Institutes, including Ben Kesel and Clive Lunny in IT, Darren Warrington in Building Services, Neesha Rana and Marna Roos in HR, and Anna Gibson in Finance and Purchasing. In addition, Donna Brown works on the PhD programme, and Clare Davy acts as Education Officer, while Michele Marron contributes her financial skills. Meanwhile, Steve Gamblin has taken on the role of Science Operations Director, and his team includes Simon Caidan and Jo Payne from NIMR and David Hudson and Nigel Peat from CRUK’s London Research Institute. These secondments and other placements offer great opportunities for our colleagues to play their part in the development of their new Institute.

The cladding, glazing and roof are almost complete, and it won’t be long until the Institute is completely watertight and we can start fitting out the labs. The Crick’s ‘Topping Out’ ceremony, to mark the completion of the shell of the building, was held on a beautiful day last summer. Paul Nurse and Chancellor George Osborne were joined by 600 guests from our partner organisations and the local community, and the occasion also saw the launch of the Crick’s Scientific Strategy ‘Discovery without Boundaries’. The Topping Out ceremony held during the summer of 2013 Image courtesy of Wellcome Images 6 MRC National Institute for Medical Research One of the important aspects of the Crick’s strategy concerns the multidisciplinary and collaborative nature of the work to be carried out, and the Institute is going to great lengths to promote this. Not only is the building itself designed to encourage interactions between its scientists, but last year saw a great deal of effort go into deciding which researcher goes where, maximising opportunities for interdisciplinary collaborations while ensuring that scientists are close to the equipment they use most often. The Institute’s interdisciplinary ethos was encouraged by retreats and awaydays for group leaders and heads of technology platforms, for postdocs, and for students. These have been very successful in introducing members of the founding institutes to each other and for making important links with our partners from King’s College London, Imperial College London and UCL. Next year will see awaydays for other members of staff, organised by NIMR’s Jo Payne and LRI’s Nigel Peat. To complement these, the Crick has hosted symposia and seminars, again designed to introduce the Crick partners to each other and to encourage interdisciplinary collaboration. When I write next year our new building will be all but finished and we’ll be preparing to move in — these are exciting times. www.crick.ac.uk The second Crick Symposium Images courtesy of the Francis Crick Institute MRC National Institute for Medical Research 7 Science overview Research Programmes at NIMR NIMR is one of the world’s leading medical research institutes. It is dedicated to studying important questions about the life processes that are relevant to all aspects of health. NIMR is the largest of the Medical Research Council’s institutes and its mission is: • • • • to carry out innovative, high-quality, biomedical research to be a major contributor to the MRC’s commitments in the training of scientists technology transfer the presentation of its science to the public Research at NIMR covers a broad spectrum of basic biomedical science, including infectious diseases, immunology, cell and developmental biology, neuroscience and structural biology. The world-class facilities for research include biological imaging resources, the MRC Biomedical NMR Centre and the UK’s largest academic facility for small animal research. There is a major emphasis on cross-disciplinary interactions, stemming from the pervasive culture of collaboration and strategic recruitment to complement and bridge scientific areas. There are research collaborations with many other academic and clinical centres in the UK and internationally, including strong links with University College London. Scientists at NIMR study normal biological processes and diseases at the molecular, cellular and whole organism level. Research is focused on four scientific areas: Infections and Immunity, Genetics and Development, Neurosciences and Structural Biology. Collaborations underpin progress in these areas, e.g. on the structure and function of molecules involved in infectious diseases, common mechanisms of nervous system and immune system development, and how the functioning of the brain arises during embryonic development. Infections and Immunity The immune system is a key part of the body’s defence against infections. Its importance is illustrated by the effects of a defective immune system, as seen in people with AIDS, which results in overwhelming infections leading to death. While an effective immune system is vital for health, an over-exuberant immune system can start to attack the body itself, a process known as autoimmunity. Autoimmunity is the cause of allergies such as hay fever and more serious conditions such as asthma, rheumatoid arthritis, and multiple sclerosis. We are analysing how the cells of the immune system are triggered to mount an immune response when faced with an infectious agent, how the process can go awry in autoimmunity, and how complex checks and balances in the system ensure activation of the immune system only when needed. Infectious diseases result from the transmission of pathogenic micro-organisms. Examples studied at NIMR include malaria, tuberculosis, AIDS and influenza which are responsible for the deaths of millions of people every year. This death toll is exerted mainly in the poorer countries of the world, and is also a significant and increasing burden for the National Health Service. Our research seeks to understand the fundamental biology of the causative micro-organisms and their interaction with hosts. We use this understanding to promote the development of new drugs, vaccines and diagnostic reagents. The study of pathogenic agents is also a rich source of important information on basic mechanisms of cell and molecular biology. Structural Biology In order to increase our basic understanding of human health we need to study the structure and function of biological molecules. Structural biologists at NIMR use a combination of experimental and theoretical approaches to determine the structure and dynamics of macromolecules such as proteins and DNA and also small molecules that act as chemical messengers or as fuel 8 MRC National Institute for Medical Research for cellular processes. Atomic-resolution information is obtained by X-ray crystallography, electron cryo-microscopy and NMR spectroscopy and this work is complemented by a range of dynamic biophysical and biochemical approaches. Our work cuts across the vastly different length and time scales that are important in biology. We study the arrangement of individual atoms at protein binding sites and their behaviour on timescales of picoseconds to nanoseconds; the dynamics of individual molecules and chemical reactions catalysed by molecular complexes which occur over microseconds to milliseconds; the assembly of viruses and dynamics of organelles within intact living cells which take many seconds or more. Our work addresses a wide variety of fundamental scientific questions with applications to human health and it is highly collaborative with other research teams at NIMR and across the national and international scientific community. Genetics and Development Understanding how a fertilised egg generates a functional organism is an important area of biology that has many implications for medicine. We are studying the fundamental mechanisms that underlie embryo development, including how cells proliferate, migrate and communicate, how stem cells form and are maintained, and how diverse cell types are generated, each at the correct location in the forming organism. A major focus is on identifying the underlying genes, how they function and are regulated, and their role in networks of molecular and cellular interactions that control developmental processes. These studies include the use of powerful genome-wide techniques and systems biology approaches in order to uncover gene regulatory networks. As many key genes that control specific processes are conserved between species, our studies are carried out in a range of model organisms that have distinct strengths for uncovering mechanisms of normal development and how defects can arise. Since similar processes and underlying molecular pathways are utilised in the adult, studies of development also reveal the basis of disorders such as cancer in which the proliferation and migration of cells is abnormal. In addition, elucidation of the normal mechanisms that maintain stem cells and that direct them to form specific cell types is essential for potential therapeutic use of these cells. Neurosciences The nervous system carries out many crucial physiological processes, including the perception of the external environment, control of movement of the organism, formation of memories, and the hormonal regulation of tissue growth and homeostasis. Understanding how the nervous system forms and functions is an important challenge in biology with significant implications for the pathogenesis and diagnosis of neurological diseases and development of therapies. We are studying how neural stem cells are maintained and differentiate to generate the multitude of neuronal subtypes found in the central and peripheral nervous system. An important aspect of our work is understanding how neurons migrate to their appropriate destination and how they find their targets to form functional neuronal circuits during development. We are analysing how the wiring, differentiation, specification and activity patterns of neurons underlie the processing of sensory information and integrate it to achieve appropriate outputs. Our work also examines the role of the nervous system and other tissues in energy balance and metabolism. These studies take place in close collaboration with developmental biologists who are exploring the molecular and cellular basis of organogenesis and body patterning. We also have fruitful collaborations with clinical colleagues to understand the genetic and developmental processes that lead to defects in the central and the peripheral nervous system. MRC National Institute for Medical Research 9 Scientific highlights Key discoveries made at the Institute during 2013 include examples from each of our four broad areas of research. Immunology and infectious disease Pavel Tolar and Justin Molloy have used atomic force microscopy to show that when B cells encounter a potentially dangerous particle they give it a tug to test the strength of binding of the particle to their immune receptors. Particles that bind strongly are acquired by the B cells and go on to trigger antibody production. These studies reveal an unexpected link between mechanical activity and immune responses, and it is possible that these might be exploited for vaccine design and for the development of more efficient antibodies. Sideview reconstruction of B cell synapses with the PMS or PLB substrates. The substrates were stained with lipid dye, DiI (red), and loaded with antigen (antiIgκ, green). B220 staining (blue) labels the B cells. Gitta Stockinger has developed a reporter mouse to identify intestinal Th17 cells even if they have switched off their characteristic production of IL-17. She has used this to show that Th17 cells in the vicinity of Peyer’s patches induce the development of IgAproducing germinal centre B cells. These play an important role in mucosal host defence in the gut and in maintaining homeostasis. This work provides evidence that Th17 cells are the crucial subset required for high affinity T cell-dependent IgA production and reveals a wider range of functions for Th17 cells. Jean Langhorne, collaborating with the Sanger Institute, has shown that transmission of the malaria parasite Plasmodium via mosquito bite rather than by injection of infected cells affects disease severity. Comparison of parasites before and after transmission through the mosquito vector showed that vector transmission regulates the expression of probable variant antigens in the erythrocytic cycle, modifies the host immune response, and regulates parasite virulence. These findings have profound implications for malaria research and provide novel targets for the development of vaccines. Mosquito transmission of P.c. chabaudi AS modifies parasite gene expression in the erythrocytic cycle. 10 MRC National Institute for Medical Research Structural biology Steve Gamblin and John McCauley have shown how structural changes mediate the transmissibility of flu viruses in humans. Haemagglutinin from a mutated version of the H5N1 virus subtype that acquired the ability to be transmissible in ferrets showed a small increase in affinity for human receptor and a marked decrease in affinity for avian receptor. The crystal structure shows that this mutant binds human receptor like other known human pandemic viruses. An algorithm was derived that predicts virus avidity without the need for working with infectious material. The SAMHD1-CtD/Vpxsm/DCAF1-CtD complex. DCAF1-CtD, is shown in grey surface, β-propeller blades are numbered. SAMHD1-CtD is red, Vpxsm is blue and a zinc ion shown as grey sphere. Comparison of H5 and H2 HA complexes with human receptor. Ian Taylor, Jonathan Stoye and Kate Bishop have described how a lentiviral accessory protein uses a normal cellular process to inactivate the viral defence system. They showed that the viral accessory protein Vpx wraps tightly around the DCAF1 molecule, a component of the cellular degradation machinery, to present a new molecular surface. These observations have implications for a new type of HIV-1 therapy using drug molecules to target the unique molecular interface between the viral accessory protein and the cellular factor. Katrin Rittinger, with researchers from Germany, has discovered how the linear ubiquitin chains that play an important role in the regulation of immune and inflammatory responses are synthesized. She solved the structure of a complex between the LUBAC subunit HOIP and ubiquitin, and identified a key catalytic residue within the active site. The study provides important mechanistic insights into how LUBAC synthesizes linear polyubiquitin chains, providing an important step towards a better understanding of this class of enzymes. The catalytic domain of HOIP (surface representation) is show in complex with the acceptor (orange) and donor (yellow) ubiquitin. MRC National Institute for Medical Research 11 Scientific highlights Neuroscience Vassilis Pachnis has shown that two planar cell polarity genes control the growth and guidance of enteric neuron projections relative to the main axes of the gut. Genetic ablation of these genes leads to profound abnormalities of gastrointestinal motility. This shows that developmental deficits of the enteric nervous system contribute to the pathogenesis of idiopathic intestinal motility disorders. Distension-evoked motor patterns of control and Celsr3-deficient (Celsr3|Wnt1) colons analysed by spatiotemporal maps. Developmental biology Karine Rizzoti and Robin Lovell Badge have characterised a population of pituitary stem cells in mice, and shown that these cells display regenerative potential. They used genetic lineage tracing tools to demonstrate that both SOX2 and SOX9-expressing progenitors can self-renew and give rise to endocrine cells in vivo, in the embryo and in the adult, showing that these cells represent tissue stem cells. This represents a first step toward the use of pituitary stem cells to modulate endocrine output and treat deficits. SOX2- and SOX9-Positive progenitors give rise to endocrine cells in the embryo and to SOX2;SOX9-doublepositive putative progenitors in the adult. 12 MRC National Institute for Medical Research In collaboration with scientists at the Gurdon Institute in Cambridge, Jim Smith and Clara Collart have identified four factors that become limiting for DNA replication during cleavage stages in the frog embryo. Over-expression of these four DNA replication factors prolongs the rapid synchronous cell cycles that occur during early embryogenesis. These experiments provide the mechanistic basis for a hypothesis put forward over thirty years ago. Top row: normal embryos undergoing cell division. Cells become smaller as development proceeds. Bottom row: embryos over-expressing the four factors. Cell size at 450 min is smaller in these embryos, indicating that cells are still undergoing rapid cell divisions. Jean-Paul Vincent and his colleagues have replaced the endogenous Drosophila Wnt protein, Wingless, with a version that is membrane-tethered and cannot spread from cell to cell. Remarkably, the resulting flies are viable, forming appendages of nearly the right size, albeit with a delay. This result might be explained by the ability of cells to ‘remember’ an earlier exposure to Wingless, and it also suggests that cell proliferation is increased by the spread of Wingless.

MRC National Institute for Medical Research 13 NIMR history and milestones 1933 Discovery of flu virus Christopher Andrewes, Patrick Laidlaw and Wilson Smith first isolated the human influenza virus. Alick Isaacs discovered interferon, a factor that can transfer a virus-resistant state to cells that had not been infected, and is now used to treat many infections and cancers. 1952 Gas chromatography 1940 1950 completed the first total synthesis of the non-aromatic steroids and identified the chemical structure of cholesterol. He received the Nobel Prize in 1975. 1936 The role of acetylcholine as a neurotransmitter Henry Dale established the chemical basis of neurotransmission and the role of acetylcholine as a neurotransmitter, receiving the Nobel Prize for this work in 1936. 14 MRC National Institute for Medical Research 1986 Globin locus control region Audrey Smith discovered how to store biological material at low temperature, pioneering techniques for the freezing of sperm, blood, bone marrow, corneas and many other tissues. 1960 1951 Steroid biosynthesis John Cornforth John Skehel revealed the structure of influenza virus proteins involved in the infection of cells, for which he was awarded the Louis-Jeantet Prize for Medicine in 1988. This work opened new perspectives for the design of antiviral drugs. 1960s Cryobiology After receiving the Nobel Prize in 1950 for his earlier discovery of partition chromatography, Archer Martin joined NIMR and with A.T James he developed gas chromatography, a technique now widely used in laboratories and the chemical industry. 1930 1981 Structure of influenza haemagglutinin 1957 Interferon 1970 1958 Immunoglobulin structure Rodney Porter was given the Nobel Prize in 1972 for the discovery of the structure of immunoglobulins. The work increased understanding of the immune system and led to novel approaches to diagnosis and therapy. 1957 Electron capture detector James Lovelock developed the electron capture detector, which was able to detect minute amounts of chemicals. It led to the detection of key atmospheric pollutants and is widely used in gas chromatography. Frank Grosveld discovered regulatory sequences that govern expression of the globin gene cluster, and that confer a copy number dependent level of transgenic gene expression. He was awarded the Louis-Jeantet Prize for Medicine in 1991. 1980 1975 DNA methylation Robin Holliday proposed that DNA methylation affected gene expression, and that changes in DNA methylation might therefore explain the switching on and off of genes during development. 1973 Long-term potentiation Tim Bliss and Terje Lømo discovered the phenomenon of synaptic long-term potentiation, one of the main mechanisms by which the brain learns and remembers. 1991 The sex determining gene 2005 Mouse model of Down syndrome Robin Lovell-Badge showed that the presence of the Sry gene on the Y chromosome is sufficient to cause the embryonic gonad to develop as testis rather than ovary. He received the Louis-Jeantet Prize for Medicine in 1995. Victor Tybulewicz created a genetically manipulated mouse that carries almost all of human chromosome 21. The resulting strain of mice has become a valuable tool in research on Down syndrome. 1993 Mesoderm-inducing factor Anne O’Garra discovered a novel transcriptomic signature that provides insights into fundamental pathogenesis of tuberculosis and has application to the development of improved diagnostic tools. 2006 Discovery of Th17 subset Jim Smith discovered that activin is a mesoderm-inducing factor, opening up understanding of how signalling factors control the formation of tissues during embryo development. 1990 2010 Transcriptome signature in human tuberculosis Gitta Stockinger defined the developmental steps that lead to the Th17 immune response. Th17 cells are important in the pathogenesis of many autoimmune diseases. 2010 2000 1989 Hox gene colinearity 1999 Eph receptors mediate cell segregation Robb Krumlauf showed that the linear relationship between the organisation of Hox genes along the chromosome and their expression along the head-to-tail axis is conserved in vertebrates. David Wilkinson uncovered a new mechanism that maintains the correct organisation of tissues, mediated by signalling through Eph receptors and ephrins. 1996 Discovery of the anterior organising centre Rosa Beddington discovered a novel signalling centre in the mouse embryo required for correct formation of the head-to-tail axis during embryonic development. 2007 AMP-activated protein kinase (AMPK) structure Steve Gamblin determined the structure of the enzyme that regulates cellular energy levels, AMPK. The discovery paves the way for better treatments of Type 2 diabetes. 2007 Malaria release mechanism Mike Blackman identified an enzyme that triggers release of the malaria parasite from infected red blood cells thereby enabling it to invade new cells. The enzyme is a new target for improved anti-malarial drug design. MRC National Institute for Medical Research 15 CAREERS PhD students The training of students, at all levels, is integral to NIMR and through the programmes we offer we strive to train biomedical leaders of the future. PhD Programme The NIMR four-year PhD programme has been designed to equip our students with the scientific and transferable skills required to make them competitive at the highest level, both nationally and internationally. Fully integrated into the NIMR PhD programme are medical undergraduate (MB BS) students who join us each year via the UCL MB PhD programme. All of our students benefit from access to the state-of-the art facilities and extensive expertise available across the Institute. We encourage innovation, interdisciplinarity and collaboration and indeed, many of our PhD students have projects which span multiple research themes, providing them with an excellent opportunity to broaden their general understanding of science and practical expertise. As a result of this, our 100 or so students significantly contribute to the research output of NIMR. On arrival at NIMR students work closely with their supervisors to develop their project proposal; they also choose a thesis committee, members of which have expertise in a range of scientific areas who will advise the student for the duration of the PhD. To support the development of our students we offer a wide range of internal training courses ranging from bioinformatics, statistics and microscopy to ethics, report preparation and presentation skills. We also run a series of careers seminars and an annual careers round table event, which reflect the broad range of careers available to PhDs. Donna Brown Director of Studies We encourage a good work-life balance and you’ll find a range of social activities here including football, fitness classes, squash and badminton, a book club, quizzes and a licensed bar. Our student representatives (see page 17) organise a number of social events including a Christmas dinner and summer barbecue attended by PhD, Sandwich, Summer and work experience students. Social activities at NIMR contribute to the spirit of collaboration which pervades science at the Institute. For those looking for a short commute, we offer onsite accommodation for 12 students. Exciting times lie ahead. In September 2014 we will launch the new Crick-NIMR PhD Programme, alongside the new Crick-LRI PhD Programme. Students starting these programmes in 2014 will register at one of the Crick partner universities: Imperial College London, King’s College London, or University College London; and transfer into the Crick with their research group in 2015 or 2016. Crick-NIMR students can take advantage of the extensive academic, training and social facilities that the Crick partner universities provide. . 16 MRC National Institute for Medical Research CAREERS Student representatives The 2013 intake of PhD students The student representatives form integral links between the student body and various parts of the Institute and the wider community. They primarily serve the students by making student opinions heard on a number of key committees within the Institute including the Ethical, Trade Union and Communication committees to name but a few. Additionally, representatives aim to inspire a sense of community amongst the students by organising regular meetings and social activities. Weekly student seminars expose students to topics outside of their primary field of interest, and allow students to receive informal feedback on their presentations, to ask questions, and to establish potential collaborations with other Divisions. One of the chief aims of this year’s committee will be to ease integration of students from other constituent institutes of the Crick by co-organising social events and importantly, an all student symposium, which will allow students the opportunity to present their work in a formal peer environment. The 2013 student representatives: Teresa McCabe, Tom Flower and Sophia Davidson 2013 Upgrade Report Prize Each year the NIMR awards a £1000 Travel Prize for the best upgrade report and a runner-up prize of a £100 Amazon voucher: The 2013 prizes were presented by the Director Jim Smith to the joint winners: Sophia Davidson (Immunoregulation) and Manuela Hess (Molecular Structure) and the runner up, Jimena Andersen (Molecular Neurobiology). Jimena Andersen, Manuela Hess and Sophia Davidson MRC National Institute for Medical Research 17 CAREERS PhD students – in their own words Ashleigh Johnston “I’ve just finished the first year of my PhD working in Eva Frickel’s lab. My project focuses on determining the role of human Guanylate Binding Proteins (hGBPs) during Toxoplasma gondii infection. NIMR always appealed to my inner research scientist. It is a renowned institute that is the birthplace of many breakthroughs - to work here cannot fail to inspire. When I was offered a position in the Frickel lab, working on such an interesting topic, I couldn’t be more excited. hGBPs are a family of large GTPases that are highly upregulated during infection with the intracellular parasite Toxoplasma gondii. I aim to verify the characteristics of these proteins during infection, thereby figuring out what role they may be playing. Over the last year I have been exposed to countless resources, techniques and experiences - we even climbed Ben Nevis as a lab! I can’t wait to see what the next three years have in store for me.” Daniel Snell “Going into the second year of my PhD with James Turner, I’m looking at the role of the X-chromosome in embryonic and postnatal growth, using the mouse as a model organism. This project gives me the opportunity to work in the exciting field of epigenetics, whilst at the same time having the potential to translate my findings into increased understanding of human disease: Turner syndrome affects about 1 in 2000 women, most of whom have a single X-chromosome (as opposed to the normal two) and as a result are of short stature and almost invariably infertile. The translational aspect is of particular relevance as concurrent with being a PhD student, I’m also a medical student on the UCL MBPhD programme. Upon completion, I intend both to see patients and at the same time carry out basic research relevant to those I treat.” 18 MRC National Institute for Medical Research CAREERS Sandwich students and work experience Sandwich placements Now, more than ever before, having practical research experience is essential for a scientific career at any level. Our sandwich placements provide students with the opportunity to fully immerse themselves in a research laboratory for 12 months and work on an independent research project. Sandwich students also have access to a wide range of lectures, seminar and training, and thus fully benefit from all that NIMR has to offer. Many of our sandwich students go on to do a PhD at NIMR or other leading research institutions. Work experience The 2013 intake of Sandwich students We encourage students from an early age to take an interest in science. Each year local school students work alongside our researchers, quite often supervised by PhD students, for periods of up to six weeks (also see Work Experience and Mentoring on page 33). Many of these students come back as undergraduate, Summer or Sandwich students. Sarah Caswell “I chose to do a Sandwich placement in order to get an idea of what working in biomedical research might be like. NIMR seemed like a perfect place to apply, due to its fantastic reputation and interesting project proposal. Working as a part of Molecular Structure has given me invaluable experience and skills, not only transferable techniques, but an idea of all aspects of how scientific research works. From NIMR other opportunities have arisen, including experience in Science Communication through volunteering at The Royal Society Family Fun days and contributing to Schools Days at the Institute. I enjoyed my year in the lab so much that I stayed on to do a summer placement project in Ian Taylor’s lab! NIMR has a very sociable environment with a large student community and fun events organised regularly. Overall I have gained a great deal whilst at NIMR, it has given me the understanding of further study that has confirmed my desire to undertake a PhD.” MRC National Institute for Medical Research 19 CAREERS Postdoctoral scientists In addition to its role in the training of PhD students, NIMR is a major centre for further research training and career development. It attracts researchers from the UK and across the world due to the breadth and quality of the research, and the emphasis on interactions and cross-disciplinary collaborations. Researchers at all stages of their career benefit from the very active programme of seminars and internal research meetings, and the availability of courses to acquire key scientific and complementary managerial skills. NIMR hosts approximately 220 postdoctoral researchers supported either by MRC core funding or externally funded fellowships. The core funding promotes careers at the postdoctoral level through three-year positions. In addition to the training and support offered to postdoctoral researchers by NIMR, the Postdoc Committee is very active arranging seminars, retreats and careers sessions as well as several social events throughout the year. In 2010 The Scientist ranked NIMR third in the UK among “Best Places to Work for Postdocs”. NIMR also has a vital role in providing research training for clinical scientists, and this is an important facilitator of translational projects and national and international collaborations. NIMR hosts many visiting postdoctoral clinical scientists from the UK and abroad carrying out research on, for example, infectious diseases and genetic disorders. The Postdoc Committee The Postdoc Committee is composed of NIMR postdocs from different divisions. It was created to inform, support and encourage communication within the postdoc community at NIMR. Importantly, the committee represents the voice of the postdoc community on a number of institute panels including the Heads of Divisions and the Postdoc Mentoring panels. This enables the postdoc community to be involved in creating an enjoyable and stimulating working environment. The committee additionally runs the postdoc website, and organises the postdoc seminar series as well as social events. Together with postdocs from LRI, the Committee is also responsible for organising the annual Crick postdoc retreat. This year’s retreat will be the third and will aim to encourage networking and collaboration between postdocs at both institutes in preparation for the move to the Francis Crick Institute in 2015. In the coming year the Committee aims to continue with current activities and increase communications between postdocs at NIMR and those at institutions that will also move into the Crick. The 2013 Postdoc committee: Luigi Martino, Melissa Burke, Robert Moon, Hania Khouri and Hakem Ben Addi. 20 MRC National Institute for Medical Research CAREERS Postdoctoral scientists – in their own words Melissa Burke, Division of Mycobacterial Research “Given my PhD is in the host response to parasite infection you won’t be surprised to know that I have strong interests in the ‘how’ of infectious diseases. I am especially interested in the host-microbe interactions that influence the outcome of infection. My postdoc position in Douglas Young’s group allows me to investigate both the microbe and host side of this equation in the context of tuberculosis. My project forms part of a collaboration with the University of Pittsburgh, and uses a systems biology approach to determine how mycobacteria behave at the gene level at different stages of infection. By improving our understanding of the mycobacteria biology we should ultimately be able to design new drugs that simultaneously target all stages of the disease. This would be a huge step forward in the field of tuberculosis research as it would simplify the current treatment regimes. Before arriving in the UK a year ago, I knew very little about NIMR. Since then I have been impressed by the strength, variety and calibre of the science being done here and the availability of cutting edge technology that will be instrumental in my project. The collaborative nature and friendliness of the people that work here is outstanding and has made me feel at home. From spontaneous scientific discussions, to hiking with the Hill-walking club and socialising in the bar, I am discovering that NIMR is a great place to work.” Luigi Martino, Division of Molecular Structure “In January 2013, I joined Katrin Rittinger’s lab at NIMR as a Career Development Fellow. My project is centred on the structural characterisation and study of the interactions of a specific class of Pattern Recognition Receptors, the NOD-like receptors (NLRs). These macromolecules play important roles in innate immunity, functioning as danger sensors and initiating inflammatory responses that lead to the production of specific cytokines. NLRs activate a number of signalling pathways and their malfunction can result in chronic inflammation and autoimmune disease. For that reason, it is important to shed light on their mechanism of function. The project is very interesting and challenging, but thanks to the vast number of experts, the friendly environment and the many excellent facilities that NIMR offers, I am convinced that I will obtain exciting results. The large postdoc community also represents another key element that makes NIMR a great place. I am very proud to be part of this research institute and I truly believe that the experience gained here will help me to step forward in my career.” MRC National Institute for Medical Research 21 CAREERS Programme Leaders Most Programme Leaders at NIMR are initially recruited on Programme Leader Track positions. This provides core support for a five-year period, which, following external review, can lead to promotion to an open-ended MRC Programme Leader appointment. This latter position provides long-term core support, subject to regular scientific review, that enables ambitious research to be carried out. A number of scientists who have established their reputation at NIMR have gone on to head institutes or university departments around the world. Pavel Tolar – Division of Immune Cell Biology – joined NIMR in 2009 “I obtained my medical degree in Prague, Czech Republic and then got interested in signalling in immune cells and did a PhD in immunology. I then decided to pursue scientific fame and went to the US for a postdoc at the NIH. I continued working in immunology and was most enthused by watching signaling processes in live cells. It was exciting to harness new imaging technology that was emerging at that time to address biological questions. Certainly for me, this was a very intuitive way of doing experiments. So when I started to look for a place to start building my own lab, I knew I would benefit from an environment where there would be enough interdisciplinary collaborations that would allow me to keep pace with emerging imaging technology. NIMR seemed like a great choice. I already knew that NIMR had the best group of immunologists on the continent. I also found out that the Institute had many great experts in other areas, all within a very collaborative environment. Of the highest interest to me, here were people that knew how to image things from developing organisms to single molecules. Setting up my own group here was a revealing experience. I felt welcome and well supported. Administrative and other burdens were almost non-existent. The NIMR structure gave me complete scientific freedom, yet I was surrounded by excellence that gave my research the inspiration needed to tackle difficult questions. I hope to make best use of the positive energy here.“ Kathy Niakan - Division of Stem Cell Biology and Developmental Genetics – joined NIMR in 2013 “I was drawn to research as an undergraduate. I always enjoyed developing and testing my own hypotheses and the possibility of discovering something new. I offered to wash dishes in a research laboratory and measured the concentration of DNA samples before being offered my own project. During this work I discovered the gene that caused a rare blood disorder and became completely hooked on research. During my PhD at UCLA I first heard of NIMR when I read Rosa Beddington’s seminal papers on mammalian embryo fate-mapping and the morphogenetic role of extra-embryonic tissues in embryo patterning, which inspired me to pursue developmental biology. Since then I have continued to investigate mechanisms of lineage specification in human embryos and stem cells as a postdoc at Harvard University and a research fellow at the University of Cambridge. The outstanding research reputation of NIMR attracted me to apply for a position. Colleagues throughout NIMR have been extremely supportive and collaborative as I have set up my laboratory. The things I value most at NIMR are the challenging and creative research atmosphere and access to cutting-edge facilities, which are expertly managed by our research support staff. Before I arrived I had extremely high expectations of NIMR, which I am pleased to say have been exceeded. I am very much looking forward to my group continuing to work in the vibrant research environment here.” 22 MRC National Institute for Medical Research CAREERS Anne O’Garra – Division of Immunoregulation – joined NIMR in 2001 “Having obtained my PhD in microbiology at NIMR, I changed fields for my postdoc to study the role of cytokines on immune function, with Gerry Klaus, in the Division of Immunology, headed by Ita Askonas. NIMR turned out to be a great place to do and discuss research. Collaborations arose easily through discussions, including at the bus-stop, in the cafeteria or in the bar. In that, NIMR has not changed. To expand my immunology training I joined the DNAX Research Institute in California, a hub for cytokine research. I stayed there for 15 years and developed an independent research programme on cytokine research. After investigating many positions in Europe, despite the fact that my long-term partner is a researcher in Paris, I decided to return to the UK, and to join NIMR. UK provides a fair arena for young researchers to develop their research career, with funding based on excellence and not politics. As compared to other institutions around the world, NIMR presented the most accessible cross-disciplinary institute, where collaborations are recognised positively, allowing paradigmchanging discoveries to be made, in a most collegial environment. Moreover support for scientists at NIMR is immense; animal research is perfectly supported by the excellent Biological Services Division and all other support staff work hard and proactively to help our research go forward. It is with all this support and collaboration that I have now successfully extended my programme to researching the immune response in tuberculosis.” Andy Oates – Division of Developmental Biology – joined NIMR in 2012 “After being spoilt by nearly ten years as a group leader at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, I wanted to continue to work in an Institute environment that offered longer-term funding. I knew of NIMR’s great reputation for developmental biology and was familiar with the work of James Briscoe and Jean-Paul Vincent. Their approach to developmental biology – using quantitative and modeling techniques – is similar to my own way of working. I was pleased to discover later that other labs here also use these approaches and we have had some interesting discussions. NIMR has an established aquatics facility – a big advantage for my research – and a Confocal Image Analysis Lab (CIAL) that provides excellent advice and ongoing support. CIAL also has an optics workshop creating microscopes (e.g. SPIM) tailored to the scientific questions that I want to answer and enabling me to carry out unique experiments. At NIMR there is a friendly, village-like atmosphere that encourages sharing and interactions between people. I also have strong links with UCL’s engineering and physics departments and look forward to the strengthened interdisciplinary opportunities that the Francis Crick Institute will offer.” MRC National Institute for Medical Research 23 CAREERS Research support NIMR offers career opportunities that can be broadly termed research support, covering many different types of jobs. Research Technicians are located within specific programmes and are directly involved in research. Laboratory Managers look after all the labs and equipment of one or more Divisions, ensuring that the science runs smoothly. Many individuals are involved in the running of NIMR’s extensive facilities. The biggest of these, Biological Services, provides a fully integrated laboratory animal and technical resource to the Institute. Finally, the Institute employs individuals in a range of non-scientific activities, including Divisional Administrators, Personal Assistants, Human Resources, Accounts, Procurement, Stores and Security. Neesha Rana – Human Resources Business Partner “I am currently employed as an HR Business Partner at NIMR. I have been working in HR for over six years with the last five years here at NIMR. I started my career as an HR Administrator working for Skanska, a Swedish construction company that work on behalf of the National Grid. Within eight months I became an HR Assistant. I then joined NIMR as an HR Advisor in October 2008. What attracted me to work here is the training and development opportunity I received. While I was working as an HR Advisor, I was able to complete my Masters in Human Resource Management, which helped with my promotion to my current position (HR Business Partner). I came to work at NIMR because it gave me the opportunity to work with such a variety of people and always learning something new which keeps me engaged and motivated. I love the social activities here at NIMR and the working environment as it brings the staff together in the true definition of an Institute.” Nikolay Nikolov – Head of Biological Computing “I did my first degree in international economics in Bulgaria but towards the end of my studies I started a part-time job as a programmer and stayed in computing ever since. Upon graduation I worked for a few years as a software engineer in Vienna before starting a PhD study focusing on database performance - making queries run faster on large databases. This led me naturally to a post-doc at the European Bioinformatics Institute (EBI) in Cambridge where I started as a Marie Curie Fellow in 2005. It changed my career in an unexpected way. Initially I had the idea to continue my previous research and work on making EBI’s massive databases more responsive. Gradually I moved towards bioinformatics and doing analysis of biological data. EBI generously co-sponsored me undertaking a masters in Computational Biology at Cambridge. After EBI I had post-docs at the Department of Chemistry, University of Cambridge and at the Wellcome Trust Sanger Institute. I joined NIMR in April 2013 as Head of Biocomputing. It is a challenging but rewarding opportunity and I am enjoying it immensely.” 24 MRC National Institute for Medical Research CAREERS Dorota Abucewicz – Research Technician, Division of Immune Cell Biology “After graduating in Poland I came to England to pursue my ambitions of working in one of the most prestigious UK organizations in the field of scientific research. In 2008 I started at NIMR as an Animal Technician. My main duties were: breeding, control and maintenance of mouse colonies as well as animal welfare. During four and a half years of being in this position I obtained a Home Office Personal Licence, which allowed me to perform experimental procedures on animals. I was given the opportunity to gain some experience in sperm and embryo cryopreservation within the Procedural Services Section and was promoted to Senior Animal Technician. Over a year ago I was fortunate to get a position as a Research Technician where my primary role is to contribute towards our Down Syndrome project. I share responsibilities of breeding and maintaining our various Down Syndrome mouse colonies with my colleagues. I provide support for experiments and make sure the lab runs smoothly on a daily basis. I feel that NIMR is a great place to work because of the wealth of knowledge and experience the staff possess, and it is somewhere I can continually develop and improve my skills.” Aomar Ayad – Computing “After studying Electronics Technology and microcomputing I worked for five years in telecommunications, in the hotel industry. I moved to NIMR in 1999 to work as an Animal Technician, pursuing my interest in working with animals. Two years later I transferred to the NIMR Computing department, working on the helpdesk and fielding technical support calls. Because of my background in telecoms I started to help with some network and telecoms installation, and later on undertook some troubleshooting and maintenance work. I was also able to attend a number of IT Engineering courses to assist my professional development in telecoms and Networking. In 2006 I took over responsibility for managing telecoms at the Institute, including telephones, voicemail plus call Logger systems, pagers and teleconferencing. I also work closely with a colleague on managing the NIMR network data centre switches, including Wi-Fi Aerohive, a backup and disaster recovery facility. We cover all buildings on the NIMR site, including labs, offices and student accommodation. Working as a team we maintain the network and telecoms infrastructure, including hardware and software, troubleshoot congestion, and gather data to inform future requirements. NIMR is like a second home for me and I enjoy the multinational environment and the wide range of people and ideas here.” MRC National Institute for Medical Research 25 CAREERS Animal Technicians NIMR is committed to ensuring a high standard of training and education for Animal Technicians and support staff at all stages of their careers. Continuous Professional Development (CPD) for Animal Technicians at NIMR includes formal and informal learning, training and experiences. Competency-based qualifications allow training specific to the individual and their work while Open University and Institute of Animal Technology qualifications deliver a wide knowledge of laboratory animal science, the 3Rs and a good background in biological sciences. Technicians are encouraged to spend time in NIMR research labs in order to gain handson experience of experimental procedures, and attend workshops and seminars held on a regular basis on subjects related to laboratory animal science. Visits to other scientific establishments, symposia and international meetings are also organised which enable technicians to gain experience in more varied aspects of laboratory animal husbandry and science, ensuring the 3Rs are embedded in all work involving animals at the Institute. Daniel Strawbridge - Animal Technician I have been an Animal Technician for just over a year now. In the past year, I have been learning on the job, gaining new practical skills and knowledge. Being an Animal Technician is very hands on, so it is important to have access to Continuing Professional Development (CPD) and training courses to further enhance my knowledge for the role. The CPD comes under a variety of formats and the training allows me the chance to become more competent and refined in the practical tasks. The assignments and workshops provide invaluable learning so that I can contribute a more professional and motivated approach. The seminars are useful as well to understand how other departments function and integrate at NIMR. I am currently working on the Level 2 Animal Technology course and I know it has made me more confident in the manner that my job is performed. Thus the animals under my care receive the best level of care and welfare. Jake Murphy - Animal Technician I started at NIMR in 2009 as a summer cover animal technician in Laidlaw Green on a zero hours contract. I trained alongside established techs in basic animal husbandry so that I could cover the daily practical routine when others were on leave. I was lucky in that at the end of my 12 week original summer cover period there was an opening for me to remain for longer. Around Nov 2009 I was successful in my application for a permanent position. I then embarked upon the probationary training programme as an animal technician which resulted in me becoming an established member of the Biological Services team in Laidlaw Green. Being an animal technician in Laidlaw Green, a genetically altered rodent breeding and experimental unit, requires an understanding of The Animals (Scientific Procedures) Act 1986 and mouse breeding along with the more general animal husbandry practical skills. In 2012 I acquired a Home Office PIL after completing the Home Office Module 1-3 course at the RVC. This has enabled me to continue developing and now I regularly perform regulated procedures to support the science. In 2012 I also started the MRC Level 2 award in animal technology which is a work-based qualification involving written and practical assignments. The assignments are all relevant to what I do daily at work with some additional research required which has given me a fuller understanding of the role I carry out. Currently my level 2 qualification is going through a mapping process at the end of which I hope to also gain an Institute of Animal Technology qualification. 26 MRC National Institute for Medical Research TRANSLATIONAL RESEARCH Support for translation Eileen Clark The Medical Research Council (MRC) supports research across the whole spectrum of medical sciences, with the aim of improving human health. The MRC’s translational research strategy aims to increase the scale and speed of progress from scientific discovery to clinical benefit. Laboratory-based studies at NIMR underpin this. Discoveries of how molecules, cells and organs are formed, regulated and function provide the knowledge that can lead to new therapies and diagnostics. This ‘intellectual property’ and its translation into products such as useful novel drugs or vaccines feeds into commercial projects that can build on this ‘know-how’, and Technology Transfer facilitates this exploitation. Some studies are closely aligned to specific human diseases and this research benefits from close interactions with clinicians. Productive exchange between basic scientists and clinicians allows model systems to be used to their greatest advantage in scientific discovery, and provides insights into the disease process in patients as well as potential treatments and improved clinical care. Technology Transfer NIMR scientists are supported by a local Research Governance and Contracts Office, which provides mechanisms and structure to allow basic technology transfer activities such as material transfer agreements, collaboration agreements and confidentiality agreements to be dealt with locally and speedily. The Office is also responsible for raising awareness of intellectual property issues and encouraging scientists to be alert to potential exploitation opportunities. MRC Technology (MRCT) is the exclusive technology transfer agent for the Medical Research Council and is responsible for translating cutting edge scientific discoveries into commercial products. In addition they have small molecule drug discovery and therapeutic antibody facilities, providing lead stage therapeutic assets to pharmaceutical and biotechnology companies. MRC Technology adds value to cutting-edge scientific discoveries through strategic patent protection and creative licensing of intellectual property (IP) or through partnered research with industry. Examples of licensed technology include transgenic mice and crystal structures. NIMR scientists have a variety of industrial collaborations and also act as consultants to a range of companies. Since May 2013 NIMR has welcomed Dr Howard Marriage as Translator/Entrepreneur in Residence. Howard has 30 years of bench to boardroom experience in biotech, pharma and academia. His role is to aid the identification of initial possibilities for translating discovery research at the Institute into products and services for preventing and treating disease. His role also involves looking for ways to use research findings to develop commercially viable health solutions which will generate income and benefit the UK economy. MRC National Institute for Medical Research 27 TRANSLATIONAL RESEARCH Clinical translation Laboratory research and animal models for human diseases provide insights that can translate into clinical benefit. Pathogens continue to blight human health and our research on infectious diseases such as HIV, tuberculosis (TB) and malaria benefits from and informs clinical practice worldwide. Psoriasis Environmental stimuli contribute to immune-mediated skin inflammatory diseases including psoriasis, but the mechanisms are largely unknown. Gitta Stockinger’s lab studies the aryl hydrocarbon receptor (AhR), a transcription factor that senses these stimuli, to investigate its involvement in psoriasis. Studies on skin biopsies show AhRactivating ligands reduce inflammation in the lesions of psoriasis patients, whereas AhR antagonists increase inflammation. Similarly, AhR signalling via the FICZ ligand reduced the inflammatory response in a) AhR deficiency exacerbates mouse model of psoriasis. Histological sections of skin from Ahr +/- and AhR the imiquimod-induced mouse model of -/- mice treated with imiquimod (IMQ) for 5 days. The plots show epidermis and scale (stratum corneum) psoriasis and AhR-deficient mice exhibited thickness during the course of IMQ treatment. b) Assessment of AhR involvement in human psoriasis. Biopsies were quartered, subjected overnight to the treatments listed, or left untreated, and then used for substantial exacerbation of the disease, RNA deep-sequencing. compared to AhR sufficient controls. Non-haematopoietic cells, in particular keratinocytes, are responsible for the hyper-inflammatory response, which involves increased reactivity to IL-1β and upregulation of AP-1 family transcription factors. The data suggest a critical role for AhR in the regulation of inflammatory responses and raise the possibility of novel therapeutic strategies in chronic inflammatory disorders. Irreversible intestinal failure Irreversible intestinal failure (IF) due to anatomical or functional loss is a devastating condition associated with significant morbidity and mortality. Although parenteral nutrition (PN) services have improved IF over the last decade, patients can suffer complications of PN. Such patients may be referred for intestinal transplantation, but many die before transplantation is Intestinal tissue engineering model.

Recent advances in stem cell intestinal organoid culture in vitro. biology have opened up intestinal tissue engineering (ITE) to provide alternatives to current treatments; the goal is to engineer intestinal constructs for use in regenerative medicine such as orthotopic transplantation and drug testing. Vivian Li’s lab in collaboration with Paolo de Coppi at UCL aims to develop a novel ITE technique, combining a decellularised intestinal scaffold with an organoid culture protocol to create a robust intestinal graft with structural and functional competence. 28 MRC National Institute for Medical Research TRANSLATIONAL RESEARCH New drugs for TB and malaria How an antibiotic works and can we improve it? D-cycloserine (DCS) is an antibiotic used solely to treat human tuberculosis, and a cornerstone drug to treat multi-drug resistant strains. Due to the importance of DCS and its potential as a starting point for future drug discovery programs, its mechanism-ofaction against Mycobacterium tuberculosis was studied for the first time in detail in Luiz de Carvalho’s lab.The results establish that DCS inhibition of D-Ala:D-Ala ligase (Ddl) is the most important site of action in M. tuberculosis. DCS only binds to one of the two putative D-Ala binding sites in Ddl and its inhibition is time-dependent. These results provide a blueprint of how DCS works and indicate a rational path for the design of improved analogues for the treatment of TB, currently underway in the laboratory. A, the structure of the antibiotic DCS. B, the newly discovered inhibitory mechanism for DCS against Mt Ddl. C, slow-onset (time-dependent) inhibition kinetics caused by DCS. A new target to inhibit multiplication of the malaria parasite N-myristoylation allows proteins to interact with membranes and inhibition of N-myristoyl transferase (NMT) can interfere with many biological processes. As part of a consortium with colleagues at Imperial College and the Universities of York and Nottingham, Tony Holder’s group has shown that NMT inhibitors block parasite replication in the red blood cell, providing the basis for development of antimalarial drugs against this new target. in the absence of NMT inhibitor 20-30 nuclei (blue) are formed and the reporter protein is in the membrane (M) fraction; in the presence of drug parasite development is stopped at ~6 nuclei and the reporter protein is largely in the soluble (S) fraction. MRC National Institute for Medical Research 29 TRANSLATIONAL RESEARCH Clinical translation Tuberculosis and HIV-TB interactions HIV-1 tuberculosis immune reconstitution inflammatory syndrome (TB-IRIS) is an immune complication of antiretroviral therapy. It has greatly increased in prevalence in the last decade, resulting from high tuberculosis rates and widespread availability of antiretroviral therapy. Mortality from this iatrogenic condition is estimated at 3%, but prior to work in Rob Wilkinson’s group the syndrome was poorly defined and management guidelines anecdotal. They have produced the widely accepted and implemented case definition and conducted the only randomised controlled trial to date to treat this condition. The results are incorporated in international guidelines. Translation of disease biomarkers of active TB into a robust and affordable point-of-care format is important for recognition, treatment monitoring, and control. Anne O’Garra and collaborators described a transcriptional signature in the blood of active TB patients that correlates with the extent of lung disease. With collaborators from South Africa (the Wilkinson group), London (Imperial College and Royal Free Hospital, UCL), Oxford and France, she has shown that this signature is distinct from that of patients with other lung diseases such as pneumonias and lung cancer and sarcoidosis. Distinguishing TB from these other diseases will accelerate treatment, allow effective early treatment monitoring to prevent worsening disease, and reduce further transmission and development of drug resistance. The Head nurse at the antiretroviral clinic where Rob Wilkinson’s work is carried out, on the occasion of the 10th anniversary of the availability of antiretroviral therapy. This therapy has had a massive impact on the lives of HIV-infected persons with tuberculosis but a medical complication that can arise is excessive inflammation due paradoxically to the improving immune response. 30 MRC National Institute for Medical Research PUBLIC OUTREACH Public engagement It has been an eventful year for outreach at NIMR. The celebration of the MRC centenary presented an ideal opportunity to expand and develop the scope of our public engagement, with thousands of people now benefiting from the chance to take part in NIMR events. NIMR Essay and Poster competitions Now in its eleventh year, our essay competition for secondary school students received 74 entries from 22 schools. The winning essayists wrote on the topics of ‘cell reprogramming’ and ‘bird flu mutations’. The winners spent a day at NIMR, chatting with some of the scientists involved in research related to their essays, and seeing how modern medical research is carried out. This year saw the introduction of a competition aimed at primary schools, in which we asked children aged 7 to 11 to design a poster highlighting the contributions of women to science. NIMR online and in the media Women in science was also the theme of a Wikipedia edit-a-thon held at NIMR in July. Staff received training in editing pages of Wikipedia and successfully created and enhanced the profile of women scientists in Wikipedia. Frequently our scientists have been on hand to provide expert comment to the media, and the Institute’s flu research featured in a special short report for BBC News. News highlights about NIMR research feature on the institute’s external website. MRC National Institute for Medical Research 31 PUBLIC OUTREACH Public engagement Visitors get a chance to experience the science at NIMR NIMR Open Day This year NIMR opened its doors to give local residents and community groups a real behind the scenes experience. The 300 visitors enjoyed a series of talks, a chance to do hands-on science experiments and a tour of some of the Institute’s labs and the library. The event concluded with the cutting of a birthday cake to mark the MRC’s 100th year. Highlights from NIMR’s Open Day event celebrating the MRC centenary. 32 MRC National Institute for Medical Research PUBLIC OUTREACH Schools’ Days The annual NIMR schools’ days in February were as popular as ever, with 357 students from over twenty local schools visiting the Institute to listen to lectures and interact with demonstrations of NIMR science. The students asked insightful questions, and were also able to discuss career opportunities in medical research. Work experience and mentoring NIMR provides a wide range of work experience opportunities, and our staff are also involved in social mobility mentoring schemes run by external organizations. From research placements in the labs, to time spent with our engineering or graphics departments, NIMR is keen to support the career development of local young people. The prestigious Nuffield awards went to four Year 12 students, who were selected this year to spend a month working on research projects in our labs. The students gained an insight into modern research, and produced reports and posters to demonstrate what they had achieved. A further thirteen young people did work experience placements in our Biological & Procedural Services department, learning about the production and maintenance of genetically altered animals, and helping out with husbandry. 2013 saw the unexpected death of Dr Michael Sargent, who had been such a driving force behind outreach at NIMR. Many of the projects above were initiated by him, including the essay competition, for which we will in future be awarding the ‘Michael Sargent Prize”. MRC National Institute for Medical Research 33 PUBLIC OUTREACH Public engagement Lectures This year marked the 60th anniversary of Edmund Hillary’s ascent on Everest. We were lucky to host a lecture by Harriet Tuckey, on her father, former NIMR scientist Dr Griffith Pugh, and his role in the expedition. NIMR scientists get out and about As always our scientists have been busy out in the community. MRC centenary events As well as our popular open day, we marked the MRC centenary with a number of other occasions and projects. We have been keen to encourage our staff to take part in these events and we have been able to provide them with training opportunities to develop their outreach skills. Some of the scientists who took up this offer were to be found entertaining the shoppers of North Finchley in June, using their “science busking” skills to engage people with NIMR science. Another of our scientists featured in the MRC’s “Strictly Science” exhibition at Imperial College, where visitors were invited to explore past and current medical research, and speculate on the future of science.

The 100 Years, 100 Scientists, 100 Schools project (left to right) Observing yeast cells on a microscope; Dressing up as water molecules; Experimenting with DNA gels. 100 Years, 100 Scientists, 100 Schools One of our largest projects to celebrate 100 years of the MRC aimed to have 100 of our NIMR scientists taking part in science activities with young people from 100 different schools in 2013. From a short walk across the road to St Vincents Primary in Mill Hill, to visiting the Linz International School in Austria, we have been taking exciting, hands-on experiments and demonstrations out to inspire the next generation. For older classes we have provided lectures on a range of topics, including flu and ‘the use of animals in research’. Looking forward to the Crick In anticipation of joining the Francis Crick Institute in 2015, we have been busy with some of the other Crick partners to assist in establishing the education and outreach programmes at the Crick. Several of our staff are collaborating with local teachers to develop workshops aimed at secondary school children, and a fantastic ‘scientific research’ comic booklet aimed at 7-11 year olds, was produced with the guidance of one of our scientists. 34 MRC National Institute for Medical Research PUBLIC OUTREACH NIMRart a NIMRart is an experimental and innovative arts programme creating opportunities for artists to make and think about art in a non-art context. A series of residencies set up in collaboration with the Arts Council and coupled with short visits, talks, exhibitions and publications has produced an ever-changing platform for ideas and creativity. By actively encouraging artists to engage with scientists and other staff at the Institute an increased consideration and comprehension of the work of both the artists and scientists involved has been achieved. NIMR also subscribes to the Arts Council Collection’s Long Loan Scheme, allowing opportunities to exhibit works by famous and established artists in our common public areas. This complements the examples obtained from the NIMRart programme and our own rolling exhibition displayed in the corridors and stairwells of images taken from current scientific projects. Loans from the Arts Council Collection include Eduardo Paolozzi, Caprese, bronze 1975. We also hosted an art project based on visual research material by Carolien Stikker and Thomas Elshuis entitled (E)MERGE. Mill Hill Essays Since 1995, NIMR has produced an annual booklet of essays to increase public awareness of topical scientific issues. Written by members of staff, each booklet includes a range of topics, ranging from emerging infections, to stem cells and cloning. They are given to visitors and distributed to local schools and other organisations.

The human immunodeficiency virus (HIV) is the most widely known retrovirus due to its impact on human health. The latest figures report that 33 million people globally are living with HIV/AIDS. A better understanding of the poorly defined early stages of retroviral infection would aid development of novel antiviral therapies for retroviral diseases, enhance the design of retroviral gene therapy vectors and help to improve models of disease. The three main projects in my laboratory investigate various aspects of these early steps. The p12 protein of murine leukaemia virus (MLV) has an unknown but essential function early in retroviral replication. Viruses carrying mutations in p12 can reverse transcribe their genomes but cannot integrate this nascent DNA. Using mutagenesis studies, we have mapped two domains in p12 that act in concert and can behave in a dominant negative manner. We have purified p12 and shown that it does not self associate in solution. We are now using a variety of biochemical and virological techniques to identify p12-interacting factors and characterise the mechanism of p12 function. In addition, we are using microscopy to visualise p12 localisation during viral replication.

Malaria causes immense suffering, killing at least one million people each year. There is no malaria vaccine, and resistance against mainstay antimalarial drugs is widespread. We need to find new ways to treat and control this devastating disease. Malaria is caused by several species of a single-celled parasite, which divides within red blood cells. These then rupture, releasing a fresh wave of parasites to invade new red cells. Our work focuses on how the parasite invades and escapes from its host cell, in anticipation that an understanding of this will aid the development of new antimalarial drugs and a vaccine. We have a particular interest in a family of enzymes that regulate parasite release from the red blood cell. We recently discovered that the activity of one of these parasite enzymes, called SUB1, is triggered by a cyclic GMP-dependent protein kinase called PKG, raising the possibility of targeting this kinase to block parasite escape. We are investigating the function and regulation of these enzymes, and searching for inhibitory compounds with potential to be developed as antimalarial drugs. We are also studying a recently identified new malarial pathogen called Plasmodium knowlesi, which causes severe malaria in parts of SE Asia.

Hunt, Hania Khoury, Gérald Larrouy-Maumus, João Pedro S. Pisco, Gareth A. Prosser The recent dissemination of strains of Mycobacterium tuberculosis (Mtb) resistant to multiple drugs constitutes a major health threat. Mankind might soon face the first epidemic of untreatable tuberculosis. Multidrug resistance arises and is selected for due to the unique biology of Mtb, its extreme adaptation to the host, and because existing therapies are inadequate. Past mycobacterial and anti-mycobacterial research programmes have clearly not been sufficiently effective at providing novel effective therapies that could reverse this trend. Innovative approaches and technologies are urgently needed to avoid a global health catastrophe. Our work has demonstrated that biochemistry and bioanalytical chemistry can lead to better understanding of phenotypes and targets, and can assist the rational design and study of novel antibacterial agents. We discovered a previously unknown glycerol phosphate phosphatase, which participates in a previously unmapped lipid polar head catabolic pathway in M. tuberculosis. Genetic and metabolomic studies led to the discovery of a previously unknown aspartate transporter, which is important for nitrogen uptake during infection. We studied in detail the mechanism-of-action of the antibiotic D-cycloserine at the molecular and cellular levels, paving the way for development of improved antibiotics.

Certain HPV types, known as highrisk types, cause cervical lesions that can progress to cancer. Cervical cancer is a major female cancer worldwide and is almost always caused by HPV. These viruses can also cause a significant proportion of head and neck tumours and have been implicated in the development of some non-melanoma skin cancers. How the body controls infection is poorly understood and currently there is no antiviral therapy that can reliably clear infection.

Virology 445:80-98 Our research aims to understand how the cellular environment regulates the papillomavirus life cycle during lesion formation, neoplastic progression and lesion regression, and is focusing in particular on the nature of the initially infected cell and subsequent disease outcome. We are particularly interested in why HPV-associated cancers are largely restricted to certain body sites, such as the cervical and anal transformation zone and the oropharynx. An important offshoot of understanding disease at this level is the development of diagnostic methodologies and an understanding of viral latency and reactivation. We are also looking at transmission and infectivity and the role of E4 amyloid fibres in optimising this process.

INFECTIONS AND IMMUNITY Parasitology Eva Frickel A new perspective on anti-Toxoplasma gondii immunity Lab members: Barbara Clough, Clémence Foltz, Ashleigh Johnston, Anna Napolitano, Anna Sanecka-Duin, Nagisa Yoshida The protozoan parasite Toxoplasma gondii infects a broad range of hosts, with a seroprevalence in man of 30%. Toxoplasma maintains an intricate balance between its own survival and host defence to achieve chronicity. IFNγ, the main cytokine responsible for its control, activates cells to restrict or kill intracellular parasites. Cell-mediated immunity, driven mostly by CD8 T cells, confers resistance to the chronic phase of infection. The outcome of an infection with Toxoplasma is determined by the host’s immune status and by the genotype of the infecting strain. Pathogenesis results from parasite burden and an over-stimulation of the immune system. Our long-term goal is to identify novel pathways and mechanisms of host resistance to Toxoplasma. We are studying how the parasitophorous vacuole (PV) is remodelled within host cells to limit parasite replication, as well as how Toxoplasma manipulates the immune system to mount an efficient, but not detrimental CD8 T cell response. We are specifically interested in the functional consequences of vacuolar recognition by IFNγ-upregulated p65 GTPases (GBPs), a yet understudied class of regulatory proteins. Additionally, we are defining the requirements for recognition and functional consequences of Toxoplasma antigen-specific CD8 T cells in the chronic phase of infection. Adoptive transfer of transnuclear (TN) CD8 T cells specific for Toxoplasma peptide Gra6 can protect mice from parasite burden. Gra6 TN CD8 mice can control Toxoplasma infection.

Many clinical manifestations and problems during treatment of tuberculosis are a direct consequence of a population of intracellular bacilli. Although in vitro and in vivo studies have shed light on some aspects of tuberculosis pathogenesis, we still do not completely understand how M. tuberculosis manages to survive in eukaryotic cells. We believe that a detailed understanding of host-mycobacteria interactions will provide insights not only into the mechanisms usurped by mycobacteria to survive, but also into basic aspects of cellular functions and in the innate immune system. Endothelial cells infected with Mycobacterium tuberculosis expressing GFP. Actin cytoskeleton is shown in red and nucleus in blue. (Photo: Tom Lerner) Research in our group focuses on the mechanisms whereby M. tuberculosis manipulates phagosome maturation and avoids killing by macrophages and non-phagocytic cells. Towards this goal, we study the intracellular transport of M. tuberculosis in macrophages, epithelial and endothelial cells using live cell imaging combined with single cell analysis. We have identified novel factors involved in vesicular trafficking and protein sorting, particularly phago-lysosome fusion, during infection. These proteins are promising candidates for being involved in the lysosomal-mediated killing of M. tuberculosis, as well as in the molecular events linking innate and adaptive immune responses.

INFECTIONS AND IMMUNITY Parasitology Tony Holder Malaria parasites and red blood cells Lab members: Samuel Abah, Muni Grainger, Judith Green, Ellen Knuepfer, Robert Moon, Sola Ogun, Kaveri Rangachari, Shigeharu Sato Malaria is caused by a parasitic protozoan that invades red blood cells, where it develops and multiplies before bursting out and invading fresh red cells. This cycle is responsible for the disease. Understanding the interaction between the parasite and the host immune system contributes to the development of a malaria vaccine. The identification of new targets for drugs to kill the parasite and interrupt the cycle of multiplication offers the potential of new therapeutic interventions. In one area of research, we have focused on N-myristoyl transferase (NMT), an enzyme that adds a C14-fatty acid to the N-terminal glycine of its protein substrates. Myristoylation allows these proteins to interact with membranes. In addition to substrates that are ubiquitous in eukaryotic cells, there are many that are unique to the biology of Apicomplexa, protists that include malaria parasites. These organisms have a surface pellicle comprised of the plasma membrane and flattened vesicles that form the inner membrane complex. Several proteins that are essential for formation and function of the pellicle are N-myristoylated. We study NMT as a potential drug target in malaria and to understand its importance in parasite cell biology.

Certain viruses cause acute infections in humans, which can be rapidly fatal within days, for example influenza A and smallpox viruses. In contrast, other viruses are able to persist chronically in infected individuals, despite induction of an immune reaction (e.g. HIV, hepatitis and herpes viruses). Almost all humans are chronically infected by one or more persistent viruses. Our understanding of the pathogenic processes of viral infection remains incomplete. In addition to facing a multiplicity of infection with exogenous viruses, all mammals, including humans, have a long-standing symbiotic relationship with a considerable number of microbial species, such as the microbiota, and endogenous retroviruses (ERVs). Recent evidence suggests that ERVs and other transposable elements actively shape gene transcriptional networks, responsible for cell identity. These networks can be responsive to environmental factors, exemplified by the response of immune cells to infection. Correspondingly, ERV activity is also responsive to external factors, providing a potential link with disease development.

This involves identification of the key components of innate and adaptive immunity that control and eliminate parasites, and regulate immunopathology. A second aspect of our work is to identify parasite molecules on the surface of the infected erythrocytes that may be responsible for antigenic variation and for binding of the parasite to host endothelium, and in this way contribute to pathology. We compared blood-stage malaria (Plasmodium chabaudi chabaudi) initiated by direct injection of infected erythrocytes (usual laboratory practice) and after mosquito transmission (natural mode of infection) to determine whether immune responses and virulence are affected. Our data show that vector transmission modifies the asexual blood-stage parasite, which then modifies the mammalian immune response, resulting in attenuated parasite growth and less pathology. Attenuated parasite virulence associates with modified expression of the pir multi-gene family. Vector transmission of Plasmodium therefore regulates gene expression of probable variant antigens in the erythrocytic cycle, modifies the elicited mammalian immune response, and thus regulates parasite virulence.

This induces the production of proteins called chemokines and cytokines, which attract other immune cells to the site of infection to stimulate the adaptive immune response. Subsequently, invading pathogens are eliminated by the resulting generation of antibodies and cytotoxic cells. We study a key signalling pathway activated during innate immune responses that is regulated by the protein kinase TPL2. Our current experiments are investigating the mechanism of TPL-2 activation by pathogen infection, and how TPL-2 regulation of cytokine and chemokine production in innate immune cells regulates inflammatory responses.

INFECTIONS AND IMMUNITY Virology John McCauley Host specificity of influenza viruses Lab members: Steve Wharton, Lauren Parker, Kerstin Beer, Michael Bennett, Donald Benton. Influenza A viruses infect a variety of species, with humans, horses and pigs representing the main mammalian hosts of the virus in which infection is sustained. Avian species, particularly water-fowl and gulls, harbour a wide variety of influenza A viruses defined by their haemagglutinin (H1-16) and neuraminidase (N19) glycoprotein subtypes in a variety of H/N combinations. New pandemic strains of human influenza virus arise from an animal reservoir either directly, as for the 2009 pandemic A(H1N1) virus, or as a result of gene reassortment between a human and an animal influenza virus, as in the 1957 and 1968 pandemics. We are investigating the determinants of host range restriction of avian and swine influenza viruses that limit their ability to infect and propagate in human cells. The interaction between a virus particle and its receptor on a host cell is a key feature that limits the host range of influenza viruses. Recent human H3N2 viruses show unexpected receptor-binding activities. The characteristics of this binding and that of other human and animal influenza viruses are being examined in collaboration with colleagues in the Divisions of Physical Biochemistry and Molecular Structure, and with Professor Ten Feizi, Imperial College London.

The immune system has developed multiple mechanisms to protect against infection. Immune cells can produce different soluble factors called cytokines to control infection, but these factors can mediate host damage if uncontrolled. Mechanisms are in place to regulate the immune response, such as the cytokine IL-10, which on the one hand can inhibit autoimmune or inflammatory diseases, however, if overproduced can contribute to chronic infection. We are building on our past results, to elucidate the molecular mechanisms for the induction and function of the regulatory cytokine IL-10 in different immune cell types and during diverse immune responses. We continue to examine mechanisms of IL-10 production and function in contributing to chronic bacterial infection with a major emphasis on tuberculosis (TB), a disease that still results in significant death world-wide. Using a systems approach we identified a blood transcriptional interferon-inducible signature in patients with active TB, which highlighted a potentially detrimental role for type I interferons during infection, and raised important implications for vaccine and therapeutic development. We continue, funded by an ERC grant, using systems approaches, molecular methods and improved mouse models of TB, to identify immune mechanisms of protection or pathogenesis important for disease control in tuberculosis and other bacterial infections.

INFECTIONS AND IMMUNITY Molecular Immunology Venizelos Papayannopoulos Mechanisms of neutrophil-mediated immune defense Lab members: Nora Branzk, Marianna Ioannou, Qiang Wang, Annika Warnatsch Multicellular organisms evolved sophisticated immune systems to protect themselves against infection. Neutrophils are recruited to sites of infection and play central microbicidal roles. They engulf and kill microbes intracellularly and release neutrophil extracellular traps (NETs). NETs are web-like structures composed of decondensed chromatin and antimicrobial proteins that trap and kill bacteria, fungi, viruses and parasites. Human patients lacking NETs are susceptible to infection with opportunistic pathogens. However, NET overabundance has also been implicated in inflammatory and autoimmune disease. We are studying how neutrophils regulate NET release to generate an efficient antimicrobial response while restricting NET-mediated damage to the host. Neutrophils release NETs through a novel cell death mechanism involving some fascinating cell biology: reactive oxygen species (ROS) trigger the selective translocation of a neutrophil-specific protease, neutrophil elastase, to the nucleus, where it cleaves histones to promote chromatin decondensation. Over the last year, we have uncovered the mechanism of selective protease release. In addition we have made significant progress in showing that neutrophils produce well-defined antimicrobial responses depending on instructions from other immune cells and environmental cues. Finally, we are exploring other novel functions of NETs in infection and inflammatory disease. 3D reconstruction depicting Candida albicans fungi (red) next to a neutrophil which has just released NETs (blue/green) Publications Metzler KD, Fuchs TA, Nauseef WM, Reumaux D, Roesler J, Schulze I, Wahn V, Papayannopoulos V and Zychlinsky A (2011) Myeloperoxidase is required for neutrophil extracellular trap formation: implications for innate immunity.

MRC National Institute for Medical Research 49 INFECTIONS AND IMMUNITY Immune Cell Biology Benedict Seddon Regulation of T cell homeostasis by antigen receptor signals and cytokines Lab members: Thea Hogan, Louise Webb, Jie Yang T lymphocytes are immune cells that play a central role in regulating immune responses. There are several T cell types, all with different functions, so having the right number and composition of these cells is essential for a normal immunity to infection. The maintenance of T cells is strictly controlled by mechanisms regulating production, cell survival and division. There are two main T cell types made in the thymus; killer CD8 and helper CD4 T cells. The thymus makes four times as many CD4 T cells as CD8 T cell for reasons that are not understood. Using an interdisciplinary approach combining mouse genetics and mathematical modeling, we asked why the thymus makes more CD4 than CD8 T cells. This showed that whilst there were equal numbers of CD4 and CD8 progenitor cells, only 1 in 14 potential killer T cells were successful in completing development, in contrast to more than half of potential helper CD4 T cells. Modelling revealed that the combination of an unexpectedly high death rate amongst all developing T cells, with a slower development time for CD8 T cells specifically resulted in a greatly reduced efficiency of CD8 T cell generation.

Th17 cells are important for host defence against fungal pathogens and are causally involved in autoimmune diseases, whereas ILC2 play important roles in lung inflammation. We developed fate reporter models for the cytokines IL-17, IL-9 and more recently IL-22 to study development of cytokine producing cells and their behaviour during infection in vivo. Fate reporters make detection independent of current cytokine production and reveal extensive plasticity in the immune system. Furthermore, in the context of an ERC-funded programme we study the role of the aryl hydrocarbon receptor (AhR) in the immune system, trying to unravel its impact on the function of different immune cells in the defence against pathogens and in inflammatory diseases such as psoriasis that are influenced by genetic as well as environmental factors.

It is thus unsurprising that a degree of coevolution has taken place resulting in the development of specific defence mechanisms by the host and of means to overcome such defences by the virus. Understanding such natural anti-viral genes might suggest novel means of combating retroviral infection. We anticipate that these studies will shed new light on the early stages of retrovirus replication and the control of cross-species infection. Restriction factors from different species are capable of recognising different retroviruses in a specific manner apparently involving multiple low-affinity interactions. However factors controlling specificity are poorly understood. We are using a combination of structural, genetic and biochemical approaches in our attempts to understand the process of virus restriction by factors such as Fv1 and Trim5α. Recent studies include an analysis of Fv1 evolution and reveal an extraordinary degree of plasticity in this gene. Subspecies of mice from different geographic locations have developed resistance to multiple genera of retroviruses suggesting on-going exposure to, and selection by, such viruses.

However, some of the most dangerous pathogens of today’s world, such as HIV, influenza or malaria, evade antibody responses, both natural and vaccine-induced. A better understanding of the mechanisms by which these pathogens trigger antibody responses will be necessary for the development of more effective vaccines. We are interested in activation of B cells that detect pathogens by their B cell antigen receptor (BCR). We are developing new techniques to image live B cells as they recognise antigen on antigen-presenting cells. Our studies focus on mechanisms that regulate antigen binding and the organisation of signalling complexes in the plasma membrane. One unique aspect of B cell recognition of antigen is that B cells actively interrogate the antigen-presenting surface using myosin-generated forces. These forces are ultimately required to extract and endocytose the antigen. We are investigating the molecular assembly and activation of the contractile elements.

Inappropriate activation of these cells can result in autoimmune diseases such as rheumatoid arthritis. We are interested in understanding the biochemical signalling pathways within lymphocytes that control the activation, survival and migration of the cells, and we study this using genetic, biochemical and cell biological approaches. Recently we have shown that the Syk tyrosine kinase is critical for B cell homeostasis, transducing signals from both the BAFF receptor and B cell antigen receptor. Mouse models of Down Syndrome Trisomy of human chromosome 21 (Hsa21) occurs in around 1 in 750 live births and the resulting gene dosage imbalance gives rise to Down syndrome, the most common form of mental retardation. In collaboration with Prof E. Fisher (UCL), we are interested in identifying genes on this chromosome, which, when present in three copies, cause the many different phenotypes of Down syndrome. We have created a novel mouse strain carrying a freely segregating copy of Hsa21, which displays many of the features of Down syndrome, including learning difficulties and cardiac abnormalities.

INFECTIONS AND IMMUNITY Immunoregulation Andreas Wack Immune response to influenza Lab members: Helena Aegerter, Stefania Crotta, Sophia Davidson, Greg Ellis, Teresa McCabe Seasonal influenza represents a constant burden to public health, and influenza pandemics due to new virus strains pose a serious global threat. The influenza virus causes damage to the infected lung tissue and induces an immune response that is necessary to eliminate the virus but at the same time contributes to lung pathology. Influenza infection also increases dramatically the susceptibility to bacterial coinfections. Both in single infections and coinfections, it is unclear which host and viral factors tip the balance between pathology and successful pathogen clearance. A better knowledge of these processes will allow intervention to enhance, attenuate or focus the immune response to infection. Our work aims to identify determinants of disease outcome. We focus on early events after infection, in particular on the interface between infected epithelium and the innate immune system. We have used primary airway epithelial cells to show that two parallel, redundant interferon-driven feedback systems act in infected epithelia. Host-dependent differences in the interferon response to influenza and their impact on the outcome of infection are also studied. Furthermore, we investigate the roles of natural killer cells and granulocytes in influenza infection and co-infection. These studies allow us to link early events in infection to subsequent immune-mediated pathology or protection. Publications Stefania Crotta, Annita Gkioka, Victoria Male, João H.

Through clinically-based studies we aim to improve knowledge of pathogenesis and thereby improve prevention and treatment. We contributed to the description of a distinct transcriptomic signature of active TB and are conducting further studies extending to the study of tuberculosis treatment monitoring. We have determined that vitamin D deficiency is highly prevalent in Cape Town, associating with susceptibility to tuberculosis both in both HIV-infected and uninfected persons. When used as an adjunct to the treatment of tuberculosis, vitamin D suppresses proinflammatory cytokine responses, and attenuates the suppressive effect of antimicrobial therapy on secretion of IL-4, CCL5, and IFN-α. This demonstrates a previously unappreciated role for vitamin D supplementation in accelerating resolution of inflammatory responses.

INFECTIONS AND IMMUNITY Molecular Immunology Mark Wilson Molecular regulation of type-2 immunity during allergy and helminth infection Lab members: Stephanie Coomes, Yashaswini Kannan, Isobel Okoye, Victoria Pelly, Lewis Entwistle, Jimena Perez-Lloret, Fiona Li A quarter of the global population is infected with one of four major parasitic helminths, making them some of the most common infectious pathogens. Immunity to intestinal helminths requires a coordinated immunological and physiological response. CD4+ T helper 2 (Th2) lymphocytes coordinate a collective type-2 immune responses essential for expulsion mechanisms, placing Th2 cells front and centre of antihelminth immunity. However, inadvertent Th2-mediated type-2 responses in the absence of infection can give rise to allergic diseases, which have increased dramatically within the past 50 years. We aim to identify the molecular mechanism underlying Th2 cell differentiation, regulation and effector function to enhance anti-helminth immunity or prevent allergies. miRNA-mediated regulation: Using murine models of infection and allergy combined with next-generation sequencing and gene manipulation technologies we have identified several molecular pathways that regulate type-2 immunity. In particular, RNA manipulation techniques have identified a network of small non-protein coding miRNAs that regulate various aspects of type-2 immunity. We are also interrogating several miRNA-regulated pathways that influence anti-inflammatory (Regulatory T cell) responses. Functional plasticity: De novo immune responses develop alongside ongoing immune responses. In collaboration with other NIMR investigators, we have identified that Th2 cells contribute to secondary immunity through re-programming mechanisms. Collectively, these studies will help facilitate helminth elimination strategies and identify novel interventions for allergic disease. Immunity is costly.

The outcome of infection depends on a complex series of interactions with the immune system, which can result in disease or in a persistent asymptomatic, latent infection. We are studying the way that M. tuberculosis evades host immunity by misdirecting innate immune recognition and by adapting to a form that resists killing by phagocytes. Ultimately, we aim to develop drugs that rapidly eliminate persisting bacteria and vaccines that elicit more effective immunity. We are using high-throughput sequencing technologies to define the genetic diversity of M. tuberculosis and to study gene regulation at transcriptional and post-transcriptional levels. We have discovered an extensive repertoire of non-coding RNAs and are exploring their function, in part through participation in SysteMTb, a European consortium using a systems biology approach to characterise the fundamental biology of TB. Our work demonstrates that genetic variation amongst clinical isolates of M. tuberculosis results in phenotypic differences in their interaction with the host innate immune system. We propose that differences in innate immune recognition drive the epidemiology of this complex disease.

The WHO Collaborating Centre for Influenza is one of six Collaborating Centres that along with 141 WHO National Influenza Centres (NICs) in 111 UN member states form the WHO Global Influenza Surveillance and Response System to track influenza viruses as they circulate around the world. Viruses are characterised antigenically and genetically, and their resistance to antiviral drugs is determined. Results of these and other analyses from each collaborating centre are used to develop recommendations for the most appropriate strains for use in seasonal influenza vaccines and provide advice to national authorities on the global and regional circulation of influenza. Recent research has focused on the ability of animal influenza viruses infecting humans to bind to sialic acid receptors. These studies contribute to the assessment of the pandemic potential of these viruses.

Vascular endothelial cells are highly specialised secretory cells that line the lumen of blood vessels, the network of tubes that carry blood to the tissues and organs of the body. Endothelial cells help regulate vital physiological processes within the vascular network, such as blood flow, blood clotting, inflammation, vessel growth and repair. They do this through the secretion a variety of molecules with vasoactive, adhesive, anti-adhesive, coagulant, angiogenic, mitogenic and inflammatory functions. Endothelial cell damage or dysfunction alters the composition or balance of the secreted molecules, and this can predispose to an increased risk of vascular disease, infection and cancer. Our goal is to understand the molecular mechanisms controlling the intracellular trafficking and regulated secretion of proteins and peptides from vascular endothelial cells. Endothelial cells store proteins and peptides for regulated secretion in special secretory granules called Weibel-Palade bodies (WPBs) . Our recent work has shown that WPBs acquire a complex mixture of Rab proteins that recruit soluble binding partners to orchestrate the delivery and secretion of a wide range of coagulant, angiogenic, mitogenic and inflammatory mediators.

Our group employs state-of-theart NMR alongside biophysical, biochemical and cell biology techniques to investigate the nature of interactions between proteins implicated in fundamental cellular and organismal processes. These include the activation of death receptor signalling, limb regeneration in the adult newt, the regulation of phospholipase C isozymes, and the role of β2-glycoprotein I in anti-phospholipid syndrome. We also contribute to research to investigate the impact of interventions into the development of the model organism Drosophila melanogaster. We have been investigating the death-inducing signalling complex (DISC) that forms when so-called death receptors are activated by ligand binding, a process crucial for maintaining appropriate levels of immune cells within the body. DISC formation leads to the activation of the ‘executioner’ cysteine proteinase caspase-8. We have developed an experimentally tractable form of full-length caspase-8 that provides a basis for detailed investigation of its structure and the regulation of its activity by binding to DISC proteins.

We use X-ray crystallography and NMR to determine the three dimensional structures and dynamics of these molecules. In combination with other biophysical, biochemical and biological techniques, the data help us elucidate the function of the proteins of interest and provide information that may be useful for the development of therapeutic approaches. Our research includes a long-standing collaboration with John Skehel (Virology) and John McCauley’s group in NIMR’s WIC. We are investigating how changes to the structural properties of the major surface glycoproteins (hemagglutinin and neuraminidase) influence the infectivity of different strains of the influenza virus. Recently we have shown how mutations to the sialic acid binding site of the avian H5N1 virus, have allowed it to acquire a strong binding preference for the human receptor over the avian equivalent. This altered binding mode now resembles that previously observed in historically significant pandemic viruses. Conversely although the recently emerged H7N9 influenza virus hemagglutinin has also acquired higher affinity for the human receptor sialic acid, it has retained high affinity binding of the avian receptor. The retention of avian receptor binding contributes to its low transmissibility due to sequestration by avian-like receptors in human mucins. Our biophysical and structural approach enables us to better understand the significance of mutations in this rapidly evolving virus. Ribbons representations of the receptor binding sites in the hemagglutinin of influenza viruses. Mutation of the Gln226 residue in avian H5N1 hemagglutinin (upper panel) changes it’s preference to high affinity binding of human receptors. Mutations of the avian H7N9 hemagglutinin (lower panel) enable it to bind the human receptor with high affinity, but unlike H7N3 it still retains the ability to bind to the avian receptor and is therefore less transmissible in humans.

In order to understand life, we need to investigate the evolutionary process that determines its form and function. Because living things encode this evolutionary heritage, studies of their properties can provide insights into the evolutionary process. Following the evolutionary path of specific components can provide important information about the characteristics of living organisms. Combining insights from physical chemistry, condensed matter physics, artificial intelligence, complexity theory, and mathematical biology, we are developing computational and theoretical methods to explore these areas. We are investigating protein evolution, exploring what the evolutionary record can tell us about the effect of mutations, and to understand how the evolution of proteins determined their observed properties. We study the evolution of HIV and endogenous retroviruses to understand the way they act now, how they might change in the future, and how they are able to shift from one host to another. We are also studying how horizontal gene transfer affects the evolution of bacteria, focusing on when the interests of the genes and the organisms conflict, as well as how behaviours such as chemotaxis evolve.

Mutations in the mitochondrial DNA can cause severe metabolic disease and are implicated in ageing, cancer, and neurodegeneration. Our studies aim to elucidate the processes of DNA replication and expression in mitochondria to better understand and treat mitochondrial dysfunction in all its myriad forms. In the past year we have developed a new approach to studying the process of replication in mitochondria, by incubating the organelles with radiochemical precursors of DNA (or RNA) synthesis (Figure 1). The new procedure has already proved its worth by revealing that mitochondrial transcripts are used as a means of protecting the lagging-strand template during the long delay between initiation of first and second strand DNA synthesis. In another approach, we aim to exploit the capacity of some cells to rid themselves of pathological mitochondrial DNA molecules. By mining microarray datasets we have identified the genesets that distinguish cells that favour wildtype mitochondrial DNAs over those that favour pathological variants (Figure 2). This information was used to devise a pharmaceutical intervention that increased the frequency of selection of wild-type mitochondrial DNA in human cells. Figure 2.

Laser-based optical methods like optical tweezers, Atomic Force Microscopy (AFM) and total internal reflection fluorescence microscopy (TIRFM) allow us to observe, track and manipulate individual molecules either in isolated preparations or within living cells. We are interested in diverse aspects of human health, including how muscles generate force and movement, how acetylcholine receptors transduce signals in the heart, and how the two strands of DNA are separated and copied. In collaboration with Martin Webb’s group, we have been studying DNA unwinding at the single molecule level using AFM, TIRFM and magnetic tweezers. With Pavel Tolar’s group we have used AFM to help understand how B cells use mechanical force to discriminate between strong and weak binding of their receptors to antigens. With Ross Breckenridge and Nigel Birdsall my team have developed methods to study M2 acetylcholine receptors in model cell lines, primary cell culture and freshly dissected, cardiac tissue slices. This opens the possibility to study receptor physiology and pharmacology under defined conditions right through to their native context. We have developed methods to visualise individual G-protein coupled receptors in model cell lines, primary cell culture and freshly dissected cardiac tissue (see Nenasheva et al. 2013).

A combination of ligation and optimised solid phase peptide synthesis can give access to many difficult to express proteins or proteins with post-translational modifications such as methylation, ubiquitinylation or phosphorylation. The demand for site– specifically modified proteins or fluorescent labelling of proteins in cells is driving the development of these emerging techniques. With the growing importance of peptides as therapeutics, ligation chemistry is also being used to synthesise privileged cyclic peptides and peptidomimetics. The research area of ligation has important applications beyond protein synthesis, both in drug discovery and chemical biology. Synthesis of proteins with post-translational modifications requires novel ligation techniques that are fully compatible with these modifications. Methods developed for preparation of these building blocks and novel ways of connecting them have expanded the synthetic flexibility of the ligation approach so that we can easily reassemble proteins from their component peptides using a straightforward procedure. The biocompatibility of amide ligation has potential for application to modify proteins in their native settings with minimal genetic manipulation and is part of an expanding effort for the application of organic chemistry to the cell. We are synthesising several self-assembling protein systems including virus-like particles. The application of a twisted amide bond to generate a thioester by acyl rearrangement.

We study the connection between normal function and disease to eventually develop therapeutic interventions. In our work, we use different biophysical, biochemical, bioinformatics and cell biology tools. We focus on neurodegenerative processes caused by misfolding and mitochondrial dysfunction. During the last year we have further advanced our understanding of the cellular function of frataxin, the protein responsible for Friedreich’s ataxia and put this research in the framework of ironsulphur biogenesis. This is an essential machine that is highly conserved from bacteria to primates. We have specifically looked into the role of a specialised Ferredoxin and its relationship with frataxin. We have characterised the interaction between Ferredoxin and the desulphurase IscS/Nfs1 that is also a frataxin partner. By modelling the molecular complex of Ferredoxin with IscS/ Nfs1 based on experimental restraints we show that Ferredoxin competes for the binding site of frataxin and interferes with the role of Ferredoxin as an electron donor. Our data provide the first structural insights into the role of Fdx in cluster assembly. We have also further advanced our studies on ataxin-1, the protein responsible for spinocerebellar ataxia type 1. We solved the structure of a complex of the AXH domain of ataxin-1 and the 143-3 protein which suggests an important role of this interaction in the normal and pathologic function of the protein. We hope that this interaction can be used for developing new and specific drugs which could rescue protein misfolding and aggregation in disease.

Our goal is to explain how RNA-binding proteins achieve and regulate target selectivity and how they control the expression of subsets of genes. We combine information obtained from NMR experiments with that obtained by other biophysical/structural techniques and by in cell/in vivo assays. ZBP1 is an oncofetal protein that controls cellular migration and, in cancer, its expression is strongly correlated with the capability of a tumour to produce metastasis. ZBP1 mediates transport and translational control of selected mRNAs (Figure 1). However, it is unclear how target recognition takes place, and we do not have at present a mechanistic model of regulation. Our work reveals how ZBP1 makes use of two domains with very different affinities and specificities to select the b-actin mRNA target (Figure 2), and fold the RNA chain. ZBP1 binding leads to the architectural rearrangement of the RNA target, and ZBP1 phosphorylation by Src may release the RNA structure imposed by the protein. Figure 2.

Pattern recognition receptors (PRRs) are the sensors of infection and activate multiple signalling pathways that lead to the production of pro-inflammatory cytokines. However, excessive activation of these pathways can also induce autoimmune disease and chronic inflammation highlighting the importance of a tight control of these processes. Members of the NOD like receptor (NLR) family act as intracellular PRRs and we are interested in providing a molecular description of their activity and elucidate how they recognise their targets and relay this information to induce a specific cellular response. A key mechanism to regulate immune and inflammatory signalling pathways is the reversible modification of proteins with ubiquitin chains, a process called ubiquitination. Chains linked via K63 and M1 (“linear chains”) are particularly important for the regulation of immune and inflammatory responses. We aim to elucidate the molecular mechanism by which specific types of ubiquitin chains are synthesised and attached to a target by E3 ubiquitin ligases. LUBAC is an E3 that specifically synthesises linear ubiquitin chains and we have been able to explain the molecular determinants underlying its chain linkage specificity using a combination of structural and biochemical approaches.

The response to DNA damage is mediated by a cascade of phosphorylation that originates at the lesion and is transduced to effector molecules and complexes. Defects in the precision of phosphorylation are a primary cause of many cancers and other diseases. By understanding the molecular basis of specificity within a web of regulatory interactions, we can determine why these processes run amok, and may be able to design drugs to combat these effects. To this end, we focus on an emerging group of proteins and modules such as 14-3-3, Forkhead-associated (FHA), BRCA1C-terminus (BRCT) and Polo-box domains that function as phosphorylationdependent adaptors or scaffolding molecules in Ser/Thr kinase pathways. Large-scale proteomics approaches are now revealing extraordinary levels of protein phosphorylation activity in response to DNA-damage and other cellular stimuli. Although we are continuing our studies of the ‘classical’ pSer/pThr binding modules, it is clear that many other protein domains are capable of this functionality. Most recently we have been able to structurally characterise such a novel phospho-interactor called Mob1which acts to localise its partner kinase Dbf2 to the mitotic spindle apparatus through binding to phosphosites created by the Cdc15 kinase. Here, Dbf2 becomes activated by Cdc15 itself permitting robust initiation of mitotic exit network signalling through a two-step scaffolding mechanism.

Hundreds of these proteins are involved in the maintenance and expression of small circles of DNA inside the mitochondrion that yield a mere 13 proteins needed for energy production. Mutations in a burgeoning set of nuclear genes have been shown to cause defects in mtDNA that result in loss of mitochondrial function. Hence, the characterisation of these gene products is critical to a full understanding of the disease and the design of rational therapeutic strategies. We aim to define the molecular basis of mtDNA loss. To this end we are studying the MPV17 family of proteins and have recently discovered that one of its members is needed for the normal distribution of mitochondrial DNA (and mitochondria) in cells (Figure 1). Gene therapy is still in its infancy, and so the best immediate prospect for treating mitochondrial dysfunction is to boost mitochondrial biogenesis. Our recent work on mitochondria and amino acid metabolism suggests that nutrient availability has a major impact on mitochondrial energy production (Figure 2). Therefore, we have begun to investigate the effects of ‘nutriceutical’ and pharmacological interventions to ameliorate mitochondrial dysfunction. Figure 2.

Malfunction of a molecular machine resulting in the breakdown of a normal cellular process is the cause of many human cancers, developmental defects, neurological disorders and other congenital disease states. In order to prevent, combat or repair defects that lead to disease it is vital that we understand how the macromolecular components of molecular machines assemble, function and cooperate with one another in order to carry out complex biological processes. To understand how molecular machines function and perform their biological task we study molecular assemblies by applying structural, biophysical and biochemical methodologies. These approaches allow us to dissect a macromolecular complex, visualise the components and examine the interactions between the molecules that make up the complex. Current projects include examining complexes that mediate transcriptional elongation, 3’-end processing and polyadenylation, analysis of the interaction of the retroviral Gag protein with host factors and structural studies of host-cell antiretroviral restriction factors and lentiviral accessory proteins.

STRUCTURAL BIOLOGY Mathematical Biology Willie Taylor Protein structure analysis and design Lab members: Michael Doran, Jens Kleinjung, Jose Saldanha Proteins are the main essential active agents in biology and without them almost none of the processes that we associate with life would take place. Proteins enact their tasks, not as the linear sequence of amino acids that defies their uniqueness, but more typically as a compact three dimensional structure. It is the aim of my group to try to understand the relationship between the protein sequence and its structure and hence its function. Recent progress was made on the prediction of protein contacts from large multiple sequence alignments. Given at least 1000 sequences, our method was able to predict intra-chain contacts that were sufficient to uniquely specify a three-dimensional structure for a number of proteins. However, application of the approach in the determination of structure is currently of limited use as the proteins that tend to have such large collections of related sequences are typically bacterial with a good chance that one of the members of the family already has a known structure that can be used for the much simpler and more reliable approach of modelling by homology. We have therefore turned our attention to application areas where structural information is sparse but the sequences remain plentiful. Current applications include the tertiary structure of RNA (in collaboration with Russell Hamilton, Biochemistry, Oxford and Michael Sadowski ex. Math. Biol., NIMR), with a view to an extension towards protein/RNA interactions. Another application area is to large molecular systems and here we have begun work on proteins in the bacterial flagellum motor (in collaboration with Shahid Khan, visiting worker, Physical Biochemistry, NIMR and Morgan Beeby, Imperial College). At NIMR, we have completed an analysis of the core protein component FliG and are now incorporating other core components. Work with Imperial will focus more on the ATPase component in combination with cryo-EM studies. Both these applications should provide data for large-scale coarse-grained molecular modelling (described in last year’s report).

Helicases are enzymes that move along double-stranded DNA, separating the strands so making them available for further processing. For correct cell maintenance and division, it is essential that there is tight control of such processing. We are interested in the mechanism and control of such processes. We are developing new optical approaches, such as reagentless biosensors, both to study this movement along DNA, but also to develop assays for a wide range of enzymatic activities. Our helicase project aims to understand how these motor proteins interacts with other proteins as well as move through DNA. Replication of certain plasmids, which contain antibiotic resistance genes and are readily transferred between bacteria, exemplifies this. Such replicating plasmids contain a specific double-stranded origin of replication, and are bound with a replication initiation factor (RepD), helicase and polymerase. By constructing this system in vitro, we study the role and mechanism of each component. The development of biosensors has included one for ADP or GDP that is suitable for real-time assays and high-throughput approaches.

This phenomenon reflects, in part, an increased demand for cellular building blocks to support proliferation, as well as a need to deal with the unique challenges that cancer cells face from their environment. Our lab is investigating the molecular mechanisms that underlie the characteristic metabolism of tumours. We are further interested in understanding how the metabolic features of individual cell types within the tumour niche influence cancer development. These studies are complemented by structurebased design of molecular biosensors to probe metabolism in vivo, at the single-cell level. One aspect of our work has focused on the glycolytic enzyme PKM2. We showed that allosteric regulation of PKM2 alters glucose metabolism to help cancer cells survive under oxidative stress elicited by low oxygen concentrations (hypoxia), a condition often encountered in tumours. We also found that small molecule activators of PKM2 disrupt this process and sensitise cancers to oxidant-induced death. Our results indicate that expression of enzymes with specific allosteric properties underlies metabolic re-programming in cancer. In collaboration with Jens Kleinjung (Mathematical Biology), we are currently using computational approaches to systematically investigate allosteric regulation mechanisms of cancer-specific metabolic enzyme isoforms.

Disruptions of dopamine signaling underlie a variety of psychomotor disorders including Parkinson’s disease and addiction diseases. mDA neurons share the ability to synthesise, package, release and reuptake the neurotransmitter dopamine as they express a common set of enzymes, for example tyrosine hydroxylase and transporters involved in these processes. However, recent studies demonstrate the presence of heterogeneous populations of mDA neurons with different molecular markers and biophysical properties. Our main goals are to decipher gene regulatory networks regulating common and distinct properties of mDA neurons. We currently focus on understanding how the developmental programmes that specify cell type identity regulate molecular and cellular traits that underlie normal function and homeostasis of mDA neurons. We use mouse embryos and in vitro differentiation of mouse embryonic stem cells to identify genes that regulate the specification, differentiation, wiring and maintenance of mDA neurons. Our experimental approaches include a combination of embryological, genetic, molecular and genomic approaches, including genetic fate mapping studies, null and conditional mutant mice, brain slice, biochemical and genome wide analyses. These studies will provide insights into how embryonic gene expression leads to mature neuronal phenotypes.

What components are required (sensors, transistors, logic gates, and predictors)? What are their biological correlates? How is their function orchestrated to achieve unity of purpose and avoid malfunction? We address these fundamental questions in two areas: brain state control and metabolic balance in mammals. Not only are these areas of medical relevance (one in four people suffer from obesity and/or insomnia), they are also amenable to modern tools for observation and manipulation. To probe the functional logic of fast interactions between cells we use optogenetic tools for millisecond control of signals from specific neuronal types. We work with transgenic mouse models and sometimes with computer-simulated virtual cells and cell systems. Ongoing projects also use imaging, electrophysiology, anatomical tracing, immunolabelling and whole-body physiological assays to explore closely interrelated themes: • Cells and mechanisms for internal body-state sensing • Regulation of firing patterns and transmitter release in brain circuits • Input / output properties of synapses, cells, and circuits • Metabolic, chemical, and electrical signalling in the hypothalamus • Brain and brain↔body orchestration • Alterations in disorders of brain function and metabolic balance Genetic targeting of “light-switches” such as excitatory ion channel ChR2 allows to establish consequences of millisecond-scale changes in define elements of vital neurocircuits.

As human and other animal embryos develop they increase in size dramatically. We wish to identify the nutritional factors and genetic networks that promote growth during development and, equally importantly, those that shut it down in adulthood. This research also aims to shed light on the complex interactions between nutrition and the genes influencing growth, metabolism and cancer. Currently, we are investigating how the growth and metabolism of some, but not other, body organs is protected against malnutrition. Much of our research uses the fruit fly Drosophila, a model organism sharing many genes with mammals. We recently developed a methodology called multi-isotope imaging mass spectrometry (MIMS), which allows organ metabolism to be quantified with unprecedented spatial resolution. We have also identified two molecular mechanisms that spare the function of the developing brain when dietary nutrients are scarce. One of these selectively protects brain growth while the other ensures that, even if growth is compromised, neuronal diversity can still be maintained.

This process of neurogenesis involves the division of stem cells and the production of neuronal precursors that migrate to specific locations and differentiate. We study the genetic programmes that regulate and coordinate these different cellular processes. We use genomic approaches to identify the genes involved in the programme of neurogenesis and we use functional assays to determine the contribution of individual genes to the different steps of neurogenesis. New neurons are added to the adult hippocampus where they have important roles in memory formation. The stem cells that generate these new neurons become quiescent in ageing animals, which might contribute to loss of memory in old age. We have identified a transcription factor that promotes the division of stem cells in the adult hippocampus (ASCL1) and another factor that promotes their quiescence (NFIX). We currently study how these factors control stem cell activity, and how their expression and function is regulated by extracellular signals provided by the stem cell niche.

Understanding how neural systems achieve this will inform us as to how healthy and diseased brains develop and maintain normal cognitive function. We use a top-down, multi-disciplinary approach that encompasses whole-brain down to the cellular level of experimental analysis. Specifically, we are investigating several inter-related aspects: 1. The relationship between biophysical diversity and neuronal function 2. The relationship between neuronal function and connectivity 3. The contribution of local and long-range connectivity to sensory perception We use the mouse model and focus on two brain regions that offer unique advantages. The olfactory bulb is comparatively simple and contains anatomically and functionally discrete local networks that may be identified in vivo and directly targeted. This sensory modality is highly significant to rodents and they are readily trained to perform sensory discrimination based on the activity of the readily accessible neuronal networks under investigation. The neo-cortex, where functional networks are typically less well defined and contain a large number of highly diverse cell types, is ideal for investigating the rules of circuit function and connectivity in complex neuronal pathways.

Normal function of the nervous system depends on the generation, at the right time and place, of integrated cellular networks made up of a large number of diverse neurons. Understanding the mechanisms that control the generation of distinct neuronal subtypes and their migration to the appropriate location is critical for comprehending normal neuronal development and for treating neuronal deficiencies. Our studies explore the mechanisms that control the development of the enteric nervous system in the gut: how enteric neurons and their progenitors migrate during embryogenesis and how they differentiate to form complex networks that regulate gut motility and secretions. We also study the mechanisms that control neuronal differentiation in the forebrain. We have identified signals that mediate cellular interactions, molecules that underlie the functional interconnection of neurons and transcription factors underlying neuronal cell fate decisions. Our studies provide novel insight into the development and function of the nervous system in normal and disease conditions.

NEUROSCIENCES Physiology and Metabolism Markus Ralser Evolution and structure of metabolic networks For a long time, cellular metabolism has been viewed as a static series of biochemical reactions. Recent research however reveals that the cellular metabolic network is in fact highly dynamic and flexible. This property is implicated in many biologically important phenomena, such as ageing, cellular robustness, and adaptation to ever changing environments. These novel properties bring metabolism centre-stage both for developing therapies against cancer and neurodegenerative disorders and for understanding the ageing process. We use a combination of mass-spectrometry based metabolomics and techniques of functional genomics to characterise cellular metabolism. This research led to the identification of a dynamic switch in central metabolism, which prevents cells from oxidative damage, and is an important mechanism during cancer metabolism. Recently, we found a second metabolic mechanism that functions as a timer of the cellular anti-stress reaction: Two metabolites, spermine and spermidine, are exported when cells encounter oxidising molecules. This export functions as rheostat regulator of cell cycle progression and gene expression (Fig 2). Figure 2. Metabolite export as time-keeper of the cellular stress response.

Neurons are found in close association with glial cells, and both cell types show remarkably diverse shapes. How these cells are generated and assemble into complex neural circuits in a coordinated manner during development remains poorly understood. To address this question, our laboratory uses the visual system of Drosophila as a model, because it enables us to dissect the stepwise development of a complex neural circuit with powerful genetic approaches and single cell resolution. We are particularly interested in elucidating the cellular and molecular mechanisms that enable photoreceptor axons to connect with target neurons within highly regular reiterated columnar and laminated synaptic units. To facilitate the identification of cell types based on their intricate branching patterns during development and in adults, we previously have devised a multicolour cell-labelling approach, called Flybow. This technique enables us to stochastically label neurons or glia in different colours in the same sample. In our recent efforts, we developed this approach further to overcome initial limitations, adding new sets of Flybow transgenes with brighter fluorescent proteins to our toolbox. In the adult Drosophila visual system, photoreceptor axons (red) are closely associated with the processes of glial cells (green).

NEUROSCIENCES Neurophysiology Andreas Schaefer Neurophysiology of behaviour: information processing in the olfactory system Lab members: Andrew Erskine, Izumi Fukunaga, Jan Herb, Becky Jordan, Nikolai Kiskin, Mihaly Kollo, Romeo Racz, Bill Wray Understanding how information is processed in the brain is a key challenge for neuroscience. We aim to tackle one aspect of this question by using the mouse olfactory system as a model to understand mechanisms of sensory object representation and how neural circuits generate these representations. To this end we employ detailed anatomical analysis, spatiotemporally controlled molecular perturbations of the local neural circuitry, and a quantitative analysis of physiological changes associated with such perturbations in vitro and in vivo, in particular in the behaving animal. Using virus-mediated modification of the early olfactory circuitry we have shown that increased inhibition accelerated odour discrimination behaviour while reducing inhibition impaired it. Whole-cell recordings in vivo now allow us to identify physiological roles of inhibition; notably, inhibition profoundly impacts the timing of principal neurons. We are further investigating the distinct functions of the two primary interneuron circuits. Using a combination of computational modelling, targeted optogenetic interference of specific circuits and whole-cell recordings in vivo, we find a double dissociation between interneuron circuits and timescales. Using large-scale, automated behavioural approaches and cell-specific optogenetic manipulations, we now aim to assess the role of these circuits in governing olfactory object identification and odour identification. Tagging individual mice with radio-frequency identification (RFID) chips allows for group housing with integrated automatic behavioural analysis. This approach is reproducible and efficient while maximizing animal welfare by minimizing stress and providing enriched, social environment (adapted from Claridge-Chang & Schaefer, 2012).

Development of dendritic arbors, spines and synapses are critical for wiring the neural circuitry and its functioning. Although a wide range of molecular components have been implicated in dendritic development, we have limited understanding of the contribution of kinases to this process. Our lab’s goal is to uncover novel kinase signaling cascades that are critical in neuronal development and function. Kinases regulate most cellular processes, however identification of their downstream targets has been challenging. We use novel chemical genetic methods to identify kinase substrates. We study CDKL5, a kinase that when mutated in humans results in a neurodevelopmental disorder with similarities to Rett-syndrome.

NEUROSCIENCES Developmental Neurobiology David Wilkinson EMBO member, FMedSci Regulation of boundary formation and neurogenesis Lab members: Megan Addison, Jordi Cayuso, Angela Cheung, Sean Constable, Mohamed Ismail, Alexei Poliakov, Hannah Somerfield, Hannah Stanforth, Harriet Taylor, Qiling Xu The formation of a sharp border and restriction of cell intermingling between regions that have distinct identity is important for establishing the correct organisation of tissues, and when disrupted underlies disease such as the metastatic spreading of cancer cells. In the vertebrate nervous system, specific borders have a further crucial role by forming distinct boundary cells that regulate neuronal differentiation and patterning. We study the zebrafish hindbrain as an amenable model for uncovering molecular mechanisms of boundary formation and neurogenesis. In previous work, we uncovered key roles of Eph receptor and ephrin signaling in border sharpening and boundary cell formation, and showed that boundary cells organise neuronal differentiation within hindbrain segments. Our ongoing studies seek to elucidate the molecular pathways by which Eph-ephrin signaling acts, and to identify further regulators of boundary formation and segmental patterning. In related work, we are dissecting how interactions of a transcriptional repressor, Plzf, and a ubiquitination adaptor protein, Btbd6, regulate neural progenitor maintenance and differentiation. These studies utilise the powerful genetic and transgenic tools available in zebrafish for imaging and the analysis of gene function, together with mathematical modelling and in vitro assays of border formation.

MRC National Institute for Medical Research 89 NEUROSCIENCES Physiology and Metabolism Mariia Yuneva Oncogenes and tumour metabolism Lab members: Wei Lin, Andy Lucas Mendez, Emma Still Altered metabolism is widely accepted as one of the hallmarks of cancer. Metabolic changes are a part of the cell-transformation programme and are thought to ensure that transformed cells have an advantage in accessing and metabolising nutrients required for cellular proliferation. This goal is achieved, however, at the expense of the normal control of metabolism. As a result, transformed cells become heavily dependent on certain nutrients and metabolic pathways. Our aim is to understand how various factors involved in cellular transformation shape the metabolic and nutrient demands of cancer cells and to exploit this knowledge towards identifying new therapeutic targets. Cancer is an extremely heterogeneous disease and creating therapies that would be most efficient against each tumour is one of the main challenges in the field. Our research has demonstrated that metabolic changes in cancer depend on both tumour-initiating genetic lesions and the tissue environment. We are employing genetics and stable isotope-based metabolomic approaches to further investigate how metabolism is changed in tumours induced by specific pro-tumourigenic events in various mammalian tissues as well as to evaluate the requirement of metabolic pathways and tumour-specific enzyme isoforms in the initiation and progression of neoplasia. NMR profiles of tissue extracts labelled with 13C-glutamine demonstrate that liver tumours induced by MYC oncogene catabolise glutamine differently from tumours induced by MET oncogene. Oncogenes and tumour suppressor genes regulate major metabolic pathways often by promoting the expression and activity of enzyme isoforms distinct from those expressed in a parental normal tissue.

Despite its complexity, the CNS is assembled in a remarkably reliable and accurate manner. This precision is necessary for the wiring of nerves into the functional neural circuits that give the CNS its function. Our research focuses on the spinal cord, which is the part of the CNS that contains the nerves that allow us to sense our environment and respond to it by moving muscles. Our studies contribute to understanding the development of the spinal cord as well as shed light on diseased and damaged nervous systems. We hope this will help in the development of therapies for these conditions. Specifically, we are interested in the cellular and molecular mechanisms responsible for the growth and pattern of the neural tube. In ventral regions of the caudal neural tube, this is governed by the secreted molecule Sonic Hedgehog (Shh). We use a range of molecular, imaging and modelling approaches to identify and reconstruct the regulatory network that controls the growth and development of the ventral neural tube. Specifically we are developing and utilising reagents and theoretical approaches that allow the single cell resolution imaging of neural tube patterning in vitro and in vivo. Mathematical simulations of a gene regulatory network reveals that it can either produce a stable spatial pattern of gene expression (top graph) or sustained temporal oscillations (bottom graph). The choice of behaviour depends on whether the green repressive link is stronger (stable spatial pattern) than the red repressive links (oscillations).

GENETICS AND DEVELOPMENT Systems Biology i Greg Elgar Regulation of early vertebrate development Lab members: Stefan Pauls, Boris Noyvert, Laura Doglio, Joseph Price, Johanna Fischer, Lillian Hunt The early development of the human embryo is an extraordinarily dynamic and exquisitely controlled process. At the molecular level events are orchestrated by a large repertoire of transcription factors, proteins that bind to regulatory regions in genomic DNA to control gene expression. Mutations in these regulatory regions can lead to developmental anomalies and disease. Many of the patterning events that occur are common to all vertebrates, as are the transcription factors and some of the regulatory code embedded in the genome. However, the protein-DNA interactions are poorly understood, as are the functional effects they mediate. We take a systems level approach to decipher the language and grammar that is encoded in regulatory DNA, particularly that fraction that is common to all vertebrates and which therefore directs some of the most fundamental aspects of vertebrate embryogenesis. We do this by combining computational approaches with functional assays in zebrafish embryos, an important and tractable model for this sort of work. Once we identify specific regulatory patterns we can search for these throughout the genome, thereby predicting other regulatory regions. It is important that we know where these regions are in the genome, and what processes they define, as mutations in them can lead to developmental disorders and genetic disease.

Typically, transcription factors regulate the expression of individual genes through complex gene regulatory networks. Our aim is to elucidate these networks using molecular and computational tools that enable a systematic and large scale approach. From a high-resolution time series of gene expression data we have developed a clear picture of the temporal landscape of gene activation in the early Xenopus embryo. We see three waves of activation between fertilisation and the onset of gastrulation. The first of these is the rapid (re-)polyadenylation of existing maternal mRNAs, which help sustain the embryo through the transcriptionally quiet cleavage stages. The second wave marks the onset of zygotic transcription, and is associated with the mid-blastula transition (MBT), where control at the molecular level passes from maternal gene products to those derived from the embryo’s own genes. The third wave we believe to be composed, at least in part, of direct targets of transcription factors activated in the second wave. Knowing the identity of the genes activated in each wave, we have a structure within which to look for links in the gene regulatory networks.

For both of these, the intestine has emerged as a prime experimental model. In the adult intestine, it is well established that Wnt signalling plays complementary roles in physiology and pathology: in normal physiology it maintains crypt stem cell compartments but when activated by mutation can lead to colon cancer. We are investigating the regulation of the Wnt pathway in intestinal stem cells and in cancer development. We aim to translate basic stem cell research to the clinic to aid cancer treatment and transplantation. We have recently redefined the Wnt activating mechanism with a series of observations that went against the current dogmas. This provides new insights into the fundamental understanding of Wnt regulation in normal homeostasis and colorectal cancer (CRC). One of our research focuses is to further characterise how APC mutations in CRC inactivate β-catenin ubiquitination. These studies may help in the development of therapies for CRC. In an independent research interest, we are studying intestinal stem cell biology in a spatially restricted manner in order to identify the molecular mechanism that defines stem cell position. Such a mechanism may represent a key regulatory process in intestinal stem cell homeostasis and tumour initiation/ progression. (A) Schematic diagram showing our novel Wnt activating mechanism.

The goal of our work is to understand how the limbs form normally during embryogenesis, the causes of limb abnormalities and disease in humans and to provide potential therapeutic approaches to block degeneration or trigger regeneration of the musculoskeletal system. At early stages of embryonic development, the forelimb and hindlimb buds are a similarly shaped mass of cells. During subsequent steps of development the progenitors are transformed into a complex of interconnected bones, muscles and tendons. These limb tissues are exquisitely sculpted to become the correct size and shape and must also form the appropriate interconnections so that each muscle group attaches to the skeleton via the correct tendon. How this network is elaborated is poorly understood. We are using animal and in vitro models and a combination of genetics, imaging and bioinformatics approaches to understand the mechanisms that control limb bud formation and the subsequent construction of the individual limb elements.

Embryo development relies on cells making choices about which cell type to become and whether to divide, move or die. During sex determination, cells of the early gonad have an additional choice to make: to become cells typical of testes or ovaries. In mammals this usually depends on the presence or absence of the Y chromosome (males are XY, females XX); more precisely to a single gene on the Y, termed Sry. This encodes a transcription factor with an HMG box type of DNA binding domain, also present in proteins encoded by the Sox gene family. We use many techniques to explore how SRY and other factors act to initiate and maintain testis or ovary differentiation, with mice as our main experimental model, Because male birds lack Sry, evolutionary comparisons use chick embryos, and our work informs the human situation, where disorders affecting sex determination can have devastating physiological and social consequences. We also study pluripotent stem cells from early embryos (ES cells) or after reprogramming from adult cells (iPS cells), and multipotent stem cells from the brain and pituitary. Certain Sox genes are critical for self-renewal and stem cell potential. We therefore explore how these genes impact on cell fate choices, and how stem cells might be exploited to aid treatments for clinical problems, including stroke, pituitary defects and cancer.

MRC National Institute for Medical Research 97 GENETICS AND DEVELOPMENT Developmental Biology Tim Mohun Heart development in vertebrates Lab members: Laurent Dupays, Alexandrine Martineau, Izabella Piotrowska, Stuart Smith, Norma Towers, Robert Wilson Formation of the heart is a complex process that begins very early in the vertebrate embryo, remodelling a simple peristaltic tube into a complex multi-chambered organ capable of supporting embryo growth. This transformation requires exquisite coordination of cell differentiation and growth to produce the dramatic changes in organ shape. Abnormalities affecting any step will have profound consequences on the foetal heart and heart defects are the most common birth defect. By studying the roles of individual genes and cell populations in normal heart development and integrating that with an understanding of heart morphogenesis, we aim to gain a better understanding of heart development and the origins of cardiac malformations. Our work combines transgenic techniques and genome-wide analysis to investigate how cardiac gene expression is regulated in the developing vertebrate embryo. Novel imaging and computer modelling procedures that we have developed allow us to examine the precise three-dimensional structure of the embryonic heart, map the patterns of gene expression in 3D and identify changes in morphology resulting from altered gene expression. This approach not only helps us to understand normal gene function in the developing heart, but also to investigate possible causes of congenital heart disease and genetic conditions (such as Down syndrome) which often result in heart malformations.

The focus of our research is to understand the influence of signalling and transcription factors on differentiation during early human development. During preimplantation development totipotent human zygotes give rise to pluripotent embryonic cells, which form the fetus, and extra-embryonic cells, which contribute to the placenta and yolk sac. We study the molecular mechanisms that regulate pluripotency and how it is disengaged during cellular differentiation in human preimplantation embryos and embryonic stem cells. We seek to define the genetic hierarchy acting during differentiation, the influence of extracellular signalling and the extent to which these mechanisms are conserved between humans and mice. The molecular basis of these early cell lineage decisions are of fundamental biological importance and have significant clinical implications for infertility, miscarriages, developmental disorders and therapeutic applications of stem cells. Mechanisms underlying human preimplantation development are poorly understood.

What principles govern transitions from parts to wholes, and determine precision and robustness? We explore these issues using a population of genetic oscillators in the vertebrate embryo termed the segmentation clock. This multi-cellular clock drives the rhythmic, sequential, and precise formation of embryonic body segments, exhibiting rich spatial and temporal phenomena spanning from molecular to tissue scales. Tissue patterning by cellular oscillations is a recent concept, and the mechanisms and molecules responsible for this astonishing activity are just beginning to be understood. We are biologists, engineers, and physicists using molecular genetics, quantitative imaging, and theoretical analysis. Because timing is key to understanding oscillations, we developed multiple-embryo time-lapse recording methods to enable quantitation and statistical treatment of somitogenesis dynamics. To understand interactions of noisy cellular oscillators and regulatory networks, we develop theoretical descriptions that are tested in embryos. We identified the first mutations that change the segmentation clock’s period, opening the door to molecular understanding of the mechanisms that control the clock’s dynamics. We are exploring new transgenic tools to follow the oscillations of the segmentation clock in real time.

These ‘morphogens’ act in a concentration-dependent manner to induce different cell types at different positions within developing tissues. One of the earliest interactions of this kind is mesoderm induction, which causes the formation of cell types such as muscle, kidney and bone, as well as the heart and vascular system. We study the events that immediately precede mesoderm induction as well as the formation of the mesoderm itself and that of the neural crest. We use frog, zebrafish and mouse embryos, as well as human and mouse ES cells, to study mesoderm-inducing factors and to ask how cells respond to them. In particular we use imaging approaches to understand how the signals exert long-range effects, and biochemical and mathematical approaches to ask how cells distinguish between different morphogen concentrations. We also use sophisticated molecular techniques to understand the genetic regulatory networks that drive the formation of specific cell types in mesoderm (including vascular cells) and neural crest. As well as helping understand development, our work will help efforts to direct stem cells down desired developmental pathways. T-box proteins Eomes, VegT and Xbra bind neural genes pax3, sox3.

Asymmetric cell division is the process by which one cell divides to give two cells with different fates. Repeated asymmetric divisions allow a fertilised egg to generate diverse cell types during development and in adult stem cells such divisions maintain the population while simultaneously generating new, differentiated cells. The goal of our group is to determine how cellular asymmetry is established and maintained over multiple divisions to create cell lineages. Specifically, we focus on understanding how asymmetry of the mitotic spindle - the machinery that segregates chromosomes during division - affects how genetic information is accurately passed down to daughter cells. Our model system is the budding yeast, Saccharomyces cerevisiae, which shows patterns of asymmetric division like those of more complex organisms. We employ highthroughput fluorescence microscopy techniques that allow us to rapidly screen the localisation, levels and dynamics of all yeast proteins and integrate them into a visual dataset. We also use novel high-throughput genomics techniques to redirect proteins to new locations within the cell and assess the effects upon cell division. Using these tools, we aim to identify the conserved mechanisms controlling asymmetric division, lineage specification and mitotic spindle function.

GENETICS AND DEVELOPMENT Stem Cell Biology and Developmental Genetics James Turner Sex chromosomes in development and disease Lab members: Fanny Decarpentrie, Elias Elinati, Takayuki Hirota, Shantha Mahadevaiah, Obah Ojarikre, Greg Polikiewicz, Mahesh Sangrithi, Daniel Snell, Alex Widger Males and females differ in their sex chromosome make-up: females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). Sex chromosomes control a variety of developmental processes, and influence male-female differences in susceptibility to diseases, e.g. cancer. We study many aspects of sex chromosome biology, focusing recently on the role of the X chromosome in germ cell development, and on X chromosome inactivation (XCI), the process that equalises X-gene dosage between males and females. We have shown that the DNA damage kinase ATR regulates the expression of X chromosome genes during spermatogenesis (see figure), and that the X chromosome is enriched in genes involved in sperm differentiation, with around 20% of all X-genes expressed only in male germ cells. These genes are likely to be important for fertility. In female eutherian mammals, XCI is mediated by the non-coding RNA Xist, but how XCI is controlled in the second largest class of mammals, the metatherians, is unknown. We have discovered a non-coding RNA, called Rsx, which exhibits features consistent with a role in XCI in these organisms. This work will allow us to better understand how non-coding RNAs regulate gene expression. Publications Male germ cells undergoing meiosis. Chromosomes are labelled with the marker SYCP3 (green).

MRC National Institute for Medical Research 103 GENETICS AND DEVELOPMENT Developmental Biology Jean-Paul Vincent FRS, EMBO member, FMedSci Patterning and homeostasis in developing epithelia Lab members: Cyrille Alexandre, Luis Alberto Baena-Lopez, Karen Beckett, Sam Crossman, Ben Drury, Satoshi Kakugawa, Joachim Kurt, Paul Langton, Hisashi Nojima, Lucy Palmer A small number of signaling molecules orchestrate growth and cell fate decisions during development. We use techniques of genome engineering and cell biology to investigate the mechanisms that control the production, spread and activity of one signal, Wingless (the main Drosophila member of the Wnt family). In a separate, but related strand of research, we aim to understand the mechanisms that trigger the elimination of cells following epithelial disruption or cell fate misspecification. These processes are relevant to tissue homoeostasis since failure to eliminate defective cells is likely to cause a variety of diseases, including cancer. We found that flies develop and grow almost normally following replacement of the endogenous Wingless coding region with a cDNA encoding a membranetethered form. This is surprising because Wingless has been thought of as an archetypical morphogen, particularly in wing progenitors. Two processes contribute to obviating the need for Wingless to spread. First, the target tissue produces its own supply of Wingless during the early period of growth and patterning. Later, after local expression terminates, the expression of key Wingless target genes persists by a mechanism akin to cellular memory. We are currently determining the molecular basis of cellular memory. Extensive apoptosis in the segmentation mutant fushi tarazu. Dying cells are marked in red with anti-activated caspase.

The multidisciplinary research of the Institute requires a range of species and models, and to meet these needs we operate and manage a number of complex animal facilities. These include an isolation/quarantine unit, containment facilities at Levels 2, 3 and 4 for animals infected with organisms potentially harmful to man and/or the environment, specialist procedural, behavioural and surgical suites, imaging and irradiation facilities, and extensive aquatic facilities. The vast majority of animals in the facility are rodents, with large numbers of genetically altered lines of mice and rats. In addition, our facilities house ferrets, rabbits, the laboratory opossum, zebrafish and Xenopus species. The size, scope and efficiency of Biological Services provide an extraordinary service to nearly all aspects of the Institute’s science as well as to many scientists elsewhere.

The laboratory opossum: Monodelphis domestica with young. RESEARCH FACILITIES We aim to meet all the needs of the scientific Divisions whilst ensuring the highest possible standards of health and welfare for all species. The Division is active in the field of laboratory animal science, conducting and promoting research and uptake of the 3Rs (replacement, reduction, refinement) and presents its work at national and international meetings. The animal care and technical staff are trained in the production, care and use of animals for research purposes to the highest standards of animal husbandry (see page 26). Additionally they provide a range of centralised procedural support. A full-time veterinary surgeon and microbiologist offer advice on the health and welfare of our animals. The Division also provides services for the incubation of fertile chicken eggs and the production of antibodies. In addition, administration and licence control under the Animals (Scientific Procedures) Act 1986, and coordination of the Institute’s Animal Welfare and Ethical Review Body, is managed by Biological Services. Procedural Service Section The Procedural Service Section provides a range of services and facilities for the production, maintenance and preservation of genetically altered rodents. The service produces up to 200 new genetically altered rodent lines each year by both transgenic and gene-targeted technologies as well as keeping up with new technologies including CRISPR nucleases and tetraploid injection, and has started providing an ES cell culture and targeting service. A full range of techniques is employed to provide a comprehensive service for the cryopreservation of rodent germplasm, and more recently the service has expanded to include cryopreservation of frog and fish spermatozoa. In addition, the section is responsible for the rederivation of new lines imported into the Institute. Every year, together with Biological Services, the Section coordinates over 150 shipments of live animals and frozen germplasm to collaborators all over the world. The staff are also skilled in a number of assisted reproductive techniques, including in vitro fertilisation and intracytoplasmic sperm injection, which are useful for maintenance of lines with poor breeding performance or to provide age-matched cohorts for experiments. The section is also committed to investigating and implementing the 3Rs by researching and developing new refinements such as non-surgical methods of embryo transfer. ES cell microinjection.

MRC National Institute for Medical Research 107 RESEARCH FACILITIES MRC Biomedical NMR Centre Tom Frenkiel Co-workers: Geoff Kelly, Alain Oregioni The MRC Biomedical NMR Centre is a multi-user facility for biomolecular liquid-state nuclear magnetic resonance (NMR) which was set up by the MRC in 1979 to provide advanced and well-supported facilities for use by scientists from NIMR and other academic research establishments. Currently 19 external groups make use of the Centre’s facilities. NMR studies of the type carried out at the Centre provide a wide range of information, ranging from the atomic-level (e.g. determining the pKa of individual ionisable groups in proteins), through to full determination of the structure and dynamics of proteins in solution. An important area of application is the identification of interaction surfaces between the components of macromolecular complexes. The Centre’s facilities currently consist of four spectrometers with 1H operating frequencies spanning 600 to 800 MHz, all configured for studies of biological macromolecules in solution. Three of the instruments have cryogenically cooled probes and two are equipped with automatic sample-changers. The Centre has recently received substantial new investment and a new spectrometer with an operating frequency of 950 MHz is expected to become operational in 2014. This will be only the second such instrument in the UK. Study of the ionisation of the N-terminal amino group of ubiquitin (in collaboration with K. Rittinger and B.

The X-ray crystallography facilities within the Division of Molecular Structure at the Institute are state-of-the art and include a high intensity X-ray source coupled with an automated robotic sample mounting system that allows the unattended screening of 80 crystals in a single experiment. Diffracting protein crystals are the culmination of an extensive series of experimental procedures that include protein purification and protein crystallisation. A range of sophisticated techniques is employed to help explore the largest number of conditions within each of the projects under investigation. These include those techniques being developed in the Protein Expression Lab together with a wide range of robotic procedures to set up multi-well dishes and to automatically screen for protein crystals. X-ray generator and automated sample mounting robot insert shows the loop used to hold the protein crystal. The Protein Expression Lab was established in 2009 to provide dedicated support to members of the Division of Molecular Structure. The facility provides a comprehensive resource for the production of recombinant proteins. Currently we offer a choice of two expression systems: bacteria and insect cells. A high-throughput pipeline for cloning DNA fragments and small-scale expression tests in E. coli has been established, allowing the generation and screening of 96 expression constructs in a week. In parallel, proteins are also expressed in insect cells using the baculovirus expression vector system (BEVS). Services include the generation and amplification of high-titre baculovirus stocks, analytical scale productions for optimisation of protein expression, and preparative scale productions. In addition, the facility maintains a vector DNA repository, provides in-house vector design, troubleshooting and training. A.

Our goal during the initial period is to provide basic bioinformatics analysis and consulting in the area of next generation sequencing (NGS), more specifically, for RNA-Seq and Chip-Seq studies. We will be working in collaboration with the High-throughput sequencing and the IT facilities to provide infrastructural support for NGS bioinformatics, in particular, workflow automation and laboratory information management systems. NGS is a new technology which offers exciting opportunities in almost every area of biomedical research. However, it comes with its own challenges – the ever increasing amount of data puts under test the existing computational infrastructure and the relative novelty of the technology means that the methods are still maturing. We will be working hard to create a world class facility that is able to address these issues and help NIMR scientists solve important biomedical research questions. Statistical analysis of genomic data MRC National Institute for Medical Research 111 RESEARCH FACILITIES Confocal imaging and analysis Yan Gu Co-workers: Donald Bell, Chen Qian, Kate Sullivan The Confocal Imaging and Analysis Laboratory (CIAL) provides an imaging core facility at NIMR. The facility covers six confocal microscopes, three wide-field fluorescence microscopes, a multiphoton microscope, a slider reader, a well-plate reader, a spinning disc microscope, a 4-channel TIRF microscope, two SPIM, two offline workstations, and image processing software such as Volocity, Imaris, Image J, Metamorph and MatLab. Currently the facility supports 170 researchers from 16 Divisions. Users operate the system, but the complexity of imaging makes support an extremely important aspect of the facility. We routinely provide users with training, troubleshooting, consultation and microscope maintenance. We also support special techniques such as thick tissue imaging, live cell experiments, 2nd harmonic generation imaging, quantitative imaging, deconvolution imaging, and automatic cell counting. Research activities in CIAL are focused on techniques of selective plane illumination microscopy, high-resolution imaging, high-throughput imaging, automatic cell segmentation and tracking, and others relevant to NIMR research. The lab has expertise in sample preparation and labelling, live or fixed sample imaging, and hardware and software development to meet the needs of NIMR researchers.

Nature Methods 8:260-268 112 MRC National Institute for Medical Research RESEARCH FACILITIES Histology Radma Mahmood Co-workers: Radhi Anand The Histology service provides a range of sectioning techniques for visualisation of tissue structure and gene expression in animal research models. By making paraffin blocks of animal tissues, we produce thin sections that when stained allow for analysis of tissues at a cellular level. Tissues are automatically processed, embedded into paraffin blocks and sectioned manually by facility histologists. Slides generated are stained for cell and nuclear structure or left unstained for the researcher’s own use. Newly acquired equipment includes the Leica automated tissue processor (ASP300) and automated slide stainer (Autostainer XL) as well as two new rotary microtomes and cryostats. The ASP300 processor utilises ten different processing programs designed to optimally maintain morphology of all tissues from mouse embryos and neonates, rats, frogs and fish, as well as human research samples. Paraffin tissue blocks are sectioned manually and the automated stainer is used for hematoxylin and eosin (H&E) staining. Special stains, such as Masson’s Trichrome for collagen, are performed manually. Shared resources available to researchers include cryostats for frozen sections and a microtome for paraffin sections. The service also provides training, protocols, and assistance for investigators on all aspects of histology, including tissue fixation, tissue processing, vibratome sectioning, enzyme histo-chemistry and immune-histochemical techniques.

Development 137:4271-4282 RESEARCH FACILITIES OPT and HREM imaging Imaging methods play an increasingly central role in enabling gene or protein activity to be linked to function and phenotype, from subcellular to whole organism levels. Within the Division of Developmental Biology, the Institute has developed dedicated facilities for imaging complex morphology and gene expression of embryonic and adult tissue in 3D using Optical Projection Tomography (OPT) and High Resolution Episcopic Microscopy (HREM). This complements existing facilities at NIMR provided by the Confocal Imaging and Analysis Lab (page 112) and Histology (page 113). Automated HREM developed at NIMR forms the basis of an ongoing project funded by the Wellcome Trust and supported by the Medical Research Council to provide comprehensive imaging of normal and mutant mouse embryos at unprecedented resolution.

MRC National Institute for Medical Research 115 RESEARCH FACILITIES RESEARCH FACILITIES Single molecule techniques Single molecule experiments give insights into how biological molecules work and how they are structured. Several research groups at NIMR apply and develop methods to study single molecules. Some of these techniques provide high-resolution images of the molecules, and others give dynamic information about the interactions between proteins, DNA, lipid membranes and small ligand molecules.. TIRF (right) and Optical Tweezers (left) are powerful tools that assist studies of motor proteins which are the molecular machines contained in every cell of the body. (Images by Gregory Mashanov and Justin Molloy) We have developed methods to visualise and manipulate single molecules, with high time resolution, using two laser-based techniques; Total Internal Reflection Fluorescence (TIRF) microscopy and Optical Tweezers (OT). TIRF microscopy uses the evanescent field associated with a totally internally reflected laser beam to excite fluorophores at the surface of a microscope coverslip. Sensitive camera systems are used to detect light emitted by the fluorophores. These measurements have a resolution of around five nanometres within 50 milliseconds. Optical Tweezers make use of radiation pressure to pick-up and manipulate individual molecules. Using fast detectors, the position of optically trapped particles are measured with nanometre precision so that forces and movements produced by single molecules can be measured. The resolution is around one nanometre every millisecond. Atomic Force Microscopy (AFM) enables us to analyse the structure of biological molecules by scanning their surface topology using a microfabricated mechanical probe or “tip”. The AFM used at NIMR (JPK NanoWizard) is ideally suited to studying biological materials in aqueous solution at room temperature. As the AFM tip is scanned over the sample it rides over molecules fixed to the surface. Deflections of the tip are measured using a laser-based position sensor producing a three-dimensional topological map of the surface. The technique is ideally suited to studies of material for which high-resolution dynamic information is required. The ultimate resolution depends on the sharpness and stiffness of the silicon tip, the mechanical properties of the specimen and also upon the mechanical stability of the laboratory and microscope system. For soft biological molecules, the resolution is around five nanometres. Upper panel shows a single actin filament and a single microtubule (MT) (by Iwan Schaap); lower panels show different phases of bacterial Plasmid DNA replication (by Claudia Arbore). 116 MRC National Institute for Medical Research RESEARCH FACILITIES Electron cryomicroscopy High-resolution cryo electron microscopy (cryoEM) enables the structure of biological molecules and larger materials to be visualised in a frozen hydrated state without fixation or staining. An aqueous solution containing the specimen is frozen very rapidly to liquid nitrogen temperatures. When cooled rapidly, water forms a glass (rather than forming ice crystals) and the embedded biological material, locked in this transparent medium, can be viewed by electron microscopy. Because the electron beam has a much shorter wavelength than visible light, individual protein molecules can be visualised. Although the image contrast of each individual molecule is low, signal averaging can yield very high resolution pictures. CryoEM is well suited to high-resolution studies of both the structure and dynamics of large proteins and protein complexes, such as cytoskeletal proteins or viral capsids. Our latest methods also enable structures within rapidly frozen mammalian cells to be visualised. By recording many digital images of a specimen held at different orientations (tomography), a three-dimensional view of the molecule or cell is obtained. Individual molecules, whole virus particles or living mammalian cells embedded in ice can be imaged in three dimensions.

Services include sample preparation, high-throughput sequencing and microarray hybridisation. Support is also provided for data analysis. The Genomics facility is equipped with state-of- the-art instrumentation for genomic sequencing, genotyping and gene expression studies. High-throughput sequencing High-throughput sequencing technologies are revolutionising molecular genetics, vastly expanding our ability to study genome structure, gene regulation and tissue differentiation. Combined with increasingly sophisticated bioinformatics analysis, these methods of massively parallel sequencing-by-synthesis are impacting on all areas of basic biological research, with their ability to generate billions of bases of high-quality DNA sequence in a matter of days. NIMR’s central nextgeneration sequencing facility supports DNA/RNA sequencing using the Illumina Genome Analyzer IIx for reads up to 150 bases for both single and paired-end runs and an Illumina HiSeq 2500 sequencer that produces up to 600 Gb in 11 days (2 x 100 bp read length). The facility has recently added the Illumina MiSeq which can achieve 2 x 300bp reads in 65 hours. Microarray Whilst the most common use of Affymetrix Genechip microarrays is to examine the level of expression of many different genes or mRNA species in a sample simultaneously, there are now chips available for other protocols. Affymetrix arrays are available for many different organisms such as Mycobacterium tuberculosis, Drosophila, Xenopus, zebrafish, chicken, dog, mouse, rat and human. The microarray facility offers full technical support in the preparation and running of RNA or DNA samples. The facility also includes the Illumina iScan System with Universal Starter Kit.

Its presence is necessitated by the work of the WHO Influenza Centre (WIC) at NIMR that involves the handling of influenza viruses from all over the world such as the novel H1N1 virus, prior to its emergence as a full-blown pandemic virus. In addition, the facility also receives poorly characterised viruses. Some of these, notably viruses from zoonotic H5N1 infections, have considerable pathogenic potential in both birds and humans. Work with poorly characterised viruses and viruses that might, or do, have pandemic potential requires a high degree of containment to prevent the spread of influenza viruses into birds or the environment, as well as operator protection to minimise the risk of handling viruses potentially harmful to man. The facility is built to Health and Safety Executive requirements and DEFRA regulations under the Specified Animals Pathogen Order. It was used for the growth and characterisation of samples of the pandemic H1N1 virus, sent from around the world at the early stages of its global spread, and to generate reference ferret antisera to the emerging pandemic viruses for virus antigenic analyses. It has also been used for the isolation and characterisation of human isolates of H5N1 avian influenza virus, for example from the Turkish outbreak in humans in 2006. The laboratory capacity has been extended to have two standard high containment laboratory areas and two laboratories equipped to handle infected small animals under high level containment. With the enhanced capacity, in addition to the virus surveillance and characterisation studies of the WIC, simultaneous studies of the mechanisms of disease causation by avian or other influenza viruses can be carried out. Features of the laboratory include: • A negative pressure air regime with HEPA filtered input and double HEPA filtered extract. • Waste treatment with heating of liquid waste and autoclave sterilisation of solid waste within the body of the laboratory. • Class III and Class I/III microbiological safety cabinets for handling samples. • Class III cabinets for handling infected small animals. • Sealable, so as to permit fumigation. • Strict codes of practice including the requirement for all workers to undergo a complete change of clothing before entering the laboratory and to shower when leaving. In addition to the Level 4 laboratory, there are 11 Level 3 laboratories scattered among the main buildings and biological research facilities at NIMR. These laboratories allow the safe handling of a number of pathogenic organisms, permitting studies of the microbiology and immunology of Mycobacterium tuberculosis, the invasion of blood cells by the malaria parasite and the growth of the retroviruses that cause AIDS. MRC National Institute for Medical Research 123 RESEARCH FACILITIES Scientific instrument research and development Martyn Stopps Co-worker: Nicholas Burczyk Scientific research often requires custom instrumentation to acquire data, control processes & automate tasks. We collaborate with scientists across the institute to develop new technology that is not commercially available, providing our researchers with cutting edge tools. Custom-built scientific instrumentation integrates software, electronics, mechanical and fluidic systems. Our research & design process includes definition of user requirements, risk analysis, development of proof-of concept devices, functional specification and prototype development. Our prototypes are evaluated in the lab and developed to meet the specific scientific requirements. A critical aspect of the instrument development process is a continuous dialogue between the research scientist and us at every stage of the development. We utilise a range of CAD techniques for schematic and printed circuit board design and 3D CAD for modelling of mechanical components and fluidic systems. We manufacture our designs within the facility; this includes electronic hardware, software for a variety of platforms and prototype mechanical components with a precision 3D printer. We also collaborate with the NIMR Mechanical Engineering team for the manufacture of precision parts. Our recent completed projects include the development of magnetic tweezers to supercoil DNA (collaboration with Justin Molloy) and a system for transferring graphene to electron-microscope grids (Peter Rosenthal). Current projects include development of a robotic high-throughput tissue handling and storage system enabling correlative imaging and histology (Troy Margrie), a fibre manipulation system for a novel multi-electrode array and olfactory test system (Andreas Schaefer). The in-house capability to develop innovative scientific instrumentation enables researchers to conduct novel experiments in emerging areas of science that would otherwise be out of reach.

Henry Dale, OM, FRS (1875-1968) Henry Dale worked at NIMR from its inception in 1914 and was the first Director, serving from 1928-1942. His research on the functions of nerve cells led to the discovery of acetylcholine as a neurotransmitter and to the chemical basis of neurotransmission. For this work he received the Nobel Prize for Physiology or Medicine in 1936. Henry Dale Archer Martin, CBE, FRS (1910-2002) Archer Martin worked at NIMR from 1948-1956. Before arriving at NIMR he worked on amino acid analysis and the development of partition chromatography for the purification of biological molecules. He received the Nobel Prize for Chemistry for this work in 1952. At NIMR he developed the method of gas-liquid chromatography, which has had far-reaching impact on the study of biochemistry. Archer Martin Rodney Porter, FRS (1917-1985) Rodney Porter worked at NIMR from 1949-1960. His research on the many specificities of antibodies led to the separation of antigen binding (Fab) and crystalline (Fc) proteolytic fragments of antibodies, an essential step for the determination of their complete sequences of amino acids. For this work he received the 1972 Nobel Prize in Physiology or Medicine. Rodney Porter John Cornforth, FRS (1914-2013) John Cornforth worked at NIMR from 1946-1962. He completed the first total synthesis of the nonaromatic steroids and in collaboration with George Popjak he identified the chemical structure of cholesterol. He received the Nobel Prize for Chemistry in 1975. John Cornforth Peter Medawar, OBE, OM, FRS (1915-1987) Peter Medawar was Director of NIMR from 1962-1971. He was one of the foremost biologists of his generation, and also a hugely gifted populariser of science. Earlier in his career he studied how the immune system rejects foreign tissue grafts and discovered the phenomenon of immune tolerance. For this work he was awarded the Nobel Prize for Physiology or Medicine in 1960. Peter Medawar 134 MRC National Institute for Medical Research Six famous alumni Rosa Beddington, FRS (1956-2001) Rosa Beddington worked at NIMR 1993-2001, as head of the Division of Mammalian Development. Her research focused on the first few days of mammalian embryo development. Over a period of twenty years her contributions ranged from incisive analysis using the methods of classical embryology to establishing the roles of specific genes and molecules in organising the embryonic body plan. Her insights were profoundly influential in general understanding of how anterior-posterior fates are acquired in mammalian embryos. Rosa Beddington Frank Grosveld, FRS (1948- ) Frank Grosveld was head of the Division of Gene Structure and Expression at NIMR from 1981-1993, subsequently moving to Erasmus University, Rotterdam. He discovered regulatory sequences that govern expression of the globin gene cluster, and that confer copy number dependence on the expression level of transgenes. He was awarded the Louis-Jeantet Prize for Medicine in 1991. Frank Grosveld Tim Bliss, FRS (1940- ) Tim Bliss worked at NIMR from 1967-2006, and was head of the Division of Neurophysiology from 1988. Together with Terje Lømo in 1973 he uncovered the phenomenon of synaptic long-term-potentiation (LTP), one of the major cellular processes underlying learning and memory. Since then he has worked on cellular mechanisms responsible for the persistent increase in synaptic efficacy that characterizes LTP, and the relationship between synaptic plasticity and memory. He was the Royal Society’s Croonian Lecturer in 2012. Tim Bliss Griffith Pugh, (1909-1994) Griffith Pugh joined the NIMR Division of Human Physiology in 1950. He became head of the Laboratory for Field Physiology in 1967 until he retired in 1975. He studied the physiological effects of altitude, temperature and exertion, combining field and laboratory research. His studies contributed to the success of the 1953 British Himalayan Expedition to Mt. Everest, of which he was a member. He also advised the British Olympic team on preparations for participation in the 1968 Olympic Games in Mexico City. Griffith Pugh Bridget Ogilvie, FRS (1938- ) Bridget Ogilvie worked at NIMR from 1963-1981, in the Division of Parasitology, on the immune response to parasites, mainly the human parasitic nematodes, hookworm and lymphatic filaria. Studying the immunogenicity of the secretions and surface coat of the parasites, she demonstrated a remarkable degree of variation, especially in the latter, as the worms pass through the different stages of their complex life cycles. After leaving NIMR she joined the Wellcome Trust, and was its Director from 1992-98. Bridget Ogilvie Robin Holliday, FRS (1932- ) Robin Holliday worked at NIMR 1965-1988, becoming head of a new Division of Genetics in 1970. He made discoveries which came to have central importance to the field of epigenetics. In 1975 he suggested that DNA methylation could be an important mechanism for the control of gene expression in higher organisms, and this has now become documented as a basic epigenetic mechanism in normal and cancer cells. He was awarded the Royal Society’s Royal Medal in 2011. Robin Holliday MRC National Institute for Medical Research 135 In memoriam John Cornforth, (1917-2013) Sir John ‘Kappa’ Cornforth died on 8 December 2013, aged 96. He worked at NIMR for 16 years (1946-62) and won the 1975 Nobel Prize for Chemistry for his work on the stereochemistry of enzyme-catalysed reactions. John Cornforth was born on 7 September 1917 in Sydney, Australia. He attended Sydney High School and entered the University of Sydney at the age of 16. He graduated in 1937 with firstclass honours and a University medal. In childhood he showed the first signs of deafness, due to otosclerosis, and gradually lost his hearing completely. After a year of postgraduate research in Australia, Cornforth was awarded one of two 1851 Exhibition scholarships in 1939 to study at Oxford with the renowned chemist Robert Robinson. The other winner of the scholarship that year was Rita Harradence, also an organic chemist, who Cornforth knew already. They married in 1941 and worked closely together throughout their careers. He said later: “Throughout my scientific career my wife has been my most constant collaborator. Her experimental skill made major contributions to the work; she has eased for me beyond measure the difficulties of communication that accompany deafness; her encouragement and fortitude have been my strongest supports.” After completing their PhD work on steroid synthesis the Cornforths worked with Robinson on penicillin, which was the major chemical project in his laboratory at Oxford during the war. Cornforth had earlier discovered what was to prove a key reaction for the synthesis of the sterols and after the war he returned to this pursuit. John and Rita Cornforth moved to NIMR in 1946, working there until 1962. John Cornforth collaborated with George Popjak, in NIMR’s Division of Biochemistry, and they began an extensive series of studies using radioisotopes to determine how cholesterol is made in the body. They found that the carbon skeleton of cholesterol is built up in a complex series of enzyme-regulated stages, entirely from two-carbon (acetyl) fragments. The work is directly relevant to understanding the action of modern cholesterol-reducing statin drugs. Cornforth said: “At NIMR I came into contact with biological scientists and formed collaborative projects with several of them. In particular George Popják and I shared an interest in cholesterol. Popják and I began to concert experiments in which the disciplines of chemistry and biochemistry could be applied to this subject. We were led to devise a complete carbon-by-carbon degradation of the ring structure of cholesterol and to identify, by means of radioactive tracers, the arrangement of the acetic acid molecules from which the system is built.” Amongst his many investigations into natural products and their biosynthesis and possible manufacture was the successful search to find a natural starting material for the manufacture of cortisone. Later work included new techniques for isotopic labelling and extensions of the stereochemistry of enzymes. The NIMR Director at the time, Charles Harington, regarded Cornforth as “being unquestionably in the first rank of organic chemists in this country”. In 1954 Cornforth seriously considered returning to Australia to work in a proposed new research institute in Melbourne but eventually decided against it, much to Harington’s relief. In 1962 Cornforth left NIMR to become joint director, with George Popjak, of the Shell Research Milstead Laboratory at Sittingbourne. This lab was created by Shell at the urging of Robert Robinson, to foster work at the interface of chemistry and biology. In 1975 Cornforth moved to the University of Sussex as Royal Society Research Professor in the Department of Applied Science, retiring in 1982. Cornforth was a modest and unassuming man. While he had hoped that his work would turn out to be important, he refrained from expecting such a grand Prize as the Nobel. “You could say it was original enough and useful enough to be considered for the Prize. But my own approach at the time was to put this resolutely out of my mind.” John Cornforth received many awards throughout his career, becoming FRS in 1953 and receiving the Royal Society’s Royal Medal (1976) and Copley Medal (1982), as well as the 1975 Nobel Prize for Chemistry, for his work on the stereochemistry of enzymecatalysed reactions, shared with Professor V. Prelog. He was made a Knight Bachelor in 1977. 136 MRC National Institute for Medical Research In memoriam James Lightbown (1918-2013) James Lightbown died on 11 April 2013, aged 94. He was a member of staff at NIMR, in the Division of Biological Standards, from 1949 to 1972, when he transferred to the National Institute for Biological Standards and Control (NIBSC). James W. Lightbown was born in Blackburn on 2 June 1918. He won a scholarship to Manchester Grammar School, then studied Pharmacy at Manchester University, 1936-41, where he was awarded the Wilde Prize in Pharmacology in 1941 for the best MSc thesis of the year. He stayed in the Department of Pharmacy at Manchester as a Demonstrator and later Assistant Lecturer, also undertaking some research work. He gained a Diploma in Bacteriology in 1948 and the following year became a member of the scientific staff in the Division of Biological Standards at NIMR. He was responsible for the assay of antibiotics and in 1950 he undertook a study tour of UK pharmaceutical manufacturers to gain experience of chemical and biological assay of penicillin, and to learn about the manufacturing processes. In 1952 he was promoted for his “great value in antibiotic assay” work and his substantial contribution to research. In 1957 he became completely responsible for antibiotic standards and by 1965 he was effectively deputy to the Head of Division, Derek Bangham, in all matters to do with standards and control. He was seen as efficient and responsible, and the Director of NIMR, Peter Medawar, had a high opinion of him. Lightbown was much involved in international standardization work, and a regular visitor to WHO in Geneva. His publications list is dominated by antibiotic standards. From the 1950s onwards he published reference standards for most of the key antibiotics, including crucial early work on assaying streptomycin and penicillins. In 1972 he became Head of the Division of Antibiotics at the newly established National Institute for Biological Standards and Control (NIBSC), where he remained until his retirement in 1983. He was awarded the OBE for services to science in 1983. I worked with Jim Lightbown a good deal - he was a great guy to work with. We built the large-scale Countercurrent Chromatography (CCC) unit and together worked on the international standard for Polyene Macrolide Antibiotics such as Candicidin and Trichomycin. This research was quite pioneering at the time and not only led to the publication of the WHO international standard for Candicidin, but also stimulated the growth of counter-current chromatography in China and eventually led to the successful development, scale-up and commercialization of CCC at Brunel University. Ian Sutherland, NIMR Engineering 1972-1989 MRC National Institute for Medical Research 137 In memoriam Michael Sargent (1943-2013) Michael Sargent died on 13 March 2013, aged 70. He was a member of scientific staff at NIMR from 1969 until his retirement in 2007. He pioneered the Institute’s outreach programme to schools and the U3A. Michael was born in 1943. He was educated at the Royal Hospital School in Suffolk, then went to Nottingham University. He chose to study botany because microbial genetics was taught chiefly in botany departments at that time. He stayed on to complete his PhD at Nottingham then spent three years as a postdoc with J. Oliver Lampen at Rutgers University in New Jersey, working on penicillinase secretion in Bacillus sp. In 1969 he was recruited by Howard Rogers to NIMR’s Division of Microbiology, to study mechanisms of cell growth and division in Bacillus subtilis. Using synchronous cultures of B. subtilis, involving the selection of essentially new-born cells by a method he devised, Michael investigated bulk patterns of synthesis of membrane proteins during the cell cycle, and the growth kinetics of individual cells by means of thymine starvation or nutritional shifts to richer media. His results, published in Nature, showed evidence for a doubling in the number of surface growth zones at nuclear segregation and an absolute requirement for DNA synthesis. After Howard Rogers retired in 1984, the Division of Microbiology was closed. Michael moved away from bacteria and joined the Laboratory of Embryogenesis headed by Jonathan Cooke. Michael’s response to the challenge of switching to a new field midcareer was characteristically strong and positive. He assiduously read the embryology literature and was soon making very valuable contributions. Indeed his contrasting background knowledge, particularly on the biochemical side, was an asset. In the early 1990’s Michael transferred to the newly formed Division of Developmental Biology headed by Jim Smith. Working with Xenopus and chick cDNA libraries, he succeeded in cloning and characterising two vertebrate homologues of the Drosophila gene Snail - a gene that is required for mesoderm formation. He helped to show that it was possible to interfere functionally with each gene in turn in chick development, establishing their roles in the origin of the neural crest and of left-right asymmetry. This work led to Michael’s co-authorship of two highly-cited papers in Science. From 1999 until his retirement in 2007, Michael worked with Tim Mohun in the Division of Developmental Biology, studying heart development in vertebrate embryos. Michael devised a reliable protocol for cryopreservation of sperm from both Xenopus laevis and its cousin, Xenopus tropicalis, a method that rapidly gained widespread use. Michael was always interested in schools and outreach activities, with expert help from his wife Jean who is a science teacher. He organised the first Schools Day at NIMR, and ran the Schools Programme at NIMR for many years: Schools Days, the Research Summer School and the School Essay Competition. For the past ten years he also organised an annual meeting at the Institute for the University of the Third Age. Towards the end of his career at NIMR, Michael was awarded a Winston Churchill Travelling Fellowship to visit Ethiopia, India and Canada in order to study the effect in later life of nutritional and other physiological stress on the developing foetus. Michael’s ideas about how the prospects for human life might improve, together with an examination of the ethical checkpoints to biomedical intervention, were discussed in his book Biomedicine and the Human Condition which was published in 2005. “Michael was the most stimulating of colleagues. He always had some new information to impart and had a fund of stories to tell. There was never a dull moment when Michael was around and his laugh could often be heard reverberating along the corridor. He was one of the most fearless of scientists; nothing daunted him, either theoretical or experimental. For example, when restriction enzymes were first used for molecular cloning they were extremely expensive. Michael set about extracting and purifying his own and soon had a stock which, characteristically, he shared with others. His advice and opinion on a wide range of ideas and techniques were valued by many people.” Roger Buxton 138 MRC National Institute for Medical Research Scientific seminars Nearly 200 seminars and lectures by visiting speakers are given at the Institute each year.

A number of functions are organised throughout the year, including quiz nights, live music, barbecues, ceilidhs and discos. The NIMROD bar is open Monday to Friday evenings and provides a relaxed atmosphere in which to meet colleagues. The club also organises a wide range of sporting activities and tournaments. These include football, volleyball, tennis, netball, running, snooker, pool, table football, table tennis and darts. In addition, a number of smaller clubs exist within NIMROD, including: • Hillwalking - regular excursions in the UK and abroad • Magazine club - allows sharing of club purchased magazines • Drama - NIMDram regularly stages performances • Gardening - exchanging knowledge and hosting an annual summer sale • Book club – roughly monthly meetings The NIMROD Committee MRC National Institute for
