Director’s foreword
This has been a very busy and successful year at NIMR. We have been doing more terrific science (see Scientific highlights, page
10), and we have completed a very successful quinquennial review. Current and former members of staff have received various
honours and awards, and we have welcomed new programme leaders to the Institute. We have also made a great deal of
progress towards establishing The Francis Crick Institute (see page 6).
The outcome of the Institute quinquennial review - confirmed by MRC Council in December - was very positive. The preparation
of the report, and its presentation to the visiting committee, showed the Institute at its best, with everyone pulling together for
a tremendous result. This is a good opportunity for me to highlight the importance to the Institute’s science of our world-class
support services: they were strongly commended by the visiting committee, and I would like to thank everyone involved for
their invaluable contributions to the life and work of the Institute. In particular, the work of Biological Services, under the expert
direction of Kathleen Mathers, was strongly praised by the review committee, confirming my own view that we have one of the
best-run facilities in the world.
My scientific proposals for the review focused on exciting new opportunities growing
from recent successes. Thus the review committee endorsed the creation of a
Division of Physiology and Metabolism, under Alex Gould, and a revitalised Division
of Neurophysiology. Together these will allow us to drive forward some critically
important emerging areas of biomedical science. Forthcoming new appointments
will help realise this vision. We also took the opportunity at the quinquennial review
to move James Briscoe and Jean-Paul Vincent to the Division of Developmental
Biology, where, as joint heads, they are bringing new approaches to understanding the
molecular and cellular mechanisms underlying embryonic development.
Institutes like NIMR thrive on turnover and the arrival of new colleagues, and we
were delighted to welcome two new Programme Leaders Track this year: Eva Frickel
and Luiz Pedro de Carvalho. Eva joins us from Hidde Ploegh’s lab at the Whitehead
Institute, where she looked at immune surveillance of Toxoplasma gondii and the
generation of parasite epitopes for recognition by CD8 T cells. Eva’s programme at
NIMR builds on these studies to identify novel pathways and mechanisms of host
resistance to Toxoplasma. Luiz Pedro de Carvalho worked as a postdoctoral fellow in
Carl Nathan’s laboratory at the Weill Cornell Medical College, where he studied host
interactions of Mycobacterium tuberculosis. In particular he contributed to LC-MSbased metabolomics methods for systems-level studies of M. tuberculosis, which forms
the basis of his new lab at NIMR.
Alex Gould
I was also delighted in the last year that my Assistant Director, John Wills, and my
Director of Research, Steve Gamblin, both received external recognition. John’s
outstanding contributions were recognised by the award of an MBE in the New Year
Honours List for services to Science, while Steve was elected to the Fellowship of the
Royal Society for his work on the structural and functional mechanisms of molecules
involved in disease processes.

The Royal Society also recognised two of our scientific alumni: Tim Bliss has been invited to deliver the 2012 Croonian Lecture,
the Society’s premier lecture in the biological sciences, and Robin Holliday has been awarded a Royal Medal. Tim’s award
recognised his work on synaptic plasticity and especially long-term potentiation and long-term depression; Robin’s medal
recognised his pioneering work on DNA-strand exchange that involved what is now known as the Holliday Junction.
We also congratulate three of our Programme Leaders who have been awarded major external grants: Troy Margrie
(Neurophysiology) has a Wellcome Trust New Investigator award, and Anne O’Garra (Immunoregulation) and Jean-Paul Vincent
(Developmental Biology) have both received grants from the European Research Council.

The Francis Crick Institute
This year has seen the former UK Centre for Medical Research and Innovation - now named The Francis Crick Institute - really
start to take shape, in terms of its people, its organisation and its building. Sir Paul Nurse, appointed as Director and Chief
Executive of The Crick, will need no introduction to the readers of this report. He took up this new leadership role at The Crick
after resigning in 2011 as President of the Rockefeller University and becoming President of the Royal Society. Through all of this,
he has never stopped working on the cell cycle and morphogenesis in fission yeast. It was for that work that he was awarded the
Nobel Prize in Physiology or Medicine in 2001.

The time capsule.
The name, The Francis Crick Institute, celebrates one of the country’s most distinguished scientists: the co-discoverer of the
structure of DNA, and someone whose work epitomised the multidisciplinary approach to be adopted by scientists at the
institute that bears his name. Francis’ daughter, Gabrielle, came to a ceremony at the site of the new Institute, along with David
Willetts MP, the Minister for Universities and Science, and Mayor Boris Johnson, to witness the burial of a time capsule. NIMR’s
contributions included many photographs of the building, our most recent Quinquennial Review, a copy of Mill Hill Essays 2010,
and a list of our collected publications, 1970–2011.

King’s College London and Imperial College London have formally joined The Francis Crick Institute, bringing their clinical and
scientific skills to the partnership. Representatives of the six partners (Imperial, King’s, UCL, the Wellcome Trust, CRUK’s London
Research Institute and NIMR) are now involved in all aspects of planning, and we are taking every opportunity to maximise our
scientific interactions to prepare for transfer into The Crick. In September 2011 we held a joint scientific retreat and we are
planning a series of joint academic ventures in the coming year.

The building itself will soon be taking shape. The planning application received its final approval early in 2011, and Laing O’Rourke
were selected to do the construction work, realising the design created by HOK and PLP Architecture. Building began in June
2011 and as I write, in December 2011, 100,000 tonnes of soil and concrete have been removed from the site. It is hard to
convey just how big the building will be: at 83,000 m2 its internal floor area will be 10% bigger than Brent Cross shopping centre
in North London and when it has been fully excavated, the waste material will be enough to fill the Albert Hall twice. Waste clay
soil is being used to help restore a bird sanctuary, while heavier material, which may contain concrete, is cleaned at a washing
plant and recycled. The building itself will be finished in the middle of 2013, and fitting-out is expected to take two years. There is
no doubt that The Francis Crick Institute will be a fantastic place to work. As we move closer to 2015 our pace of progress will
continue to accelerate: keep an eye on the NIMR and Crick websites for details.

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. NIMR’s 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.

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. Much
of our work focuses on the development of specific tissues such as the nervous system, heart, liver, gonads and limbs. As many
of the 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 many
of the same 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 underlies the processing of sensory information and integrates 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.
Structural Biology
Biological systems consist of large molecules such as proteins and DNA, and small molecules that act as substrates and signals
to drive and control cellular processes. Understanding of the molecular basis of biological processes requires analysis at the level
of the structure and interactions of individual molecules. We study the three-dimensional structures and chemical reactions that
underlie the functions of a range of biologically active and medically important molecules. We use theoretical approaches that
enable us to model molecular structures from gene sequences and generate predictive models about the dynamics of molecular
interactions. Structural methods include X-ray crystallography, electron cryo-microscopy and NMR spectroscopy that yield high
resolution information. This is complemented by a diversity of biophysical and biochemical approaches, single molecule methods
and synthetic organic chemistry that enable analysis of molecular interactions both in vitro and within living cells. Our work covers
a diversity of biology systems and is highly collaborative, for example with teams at NIMR who are studying infectious diseases
and fundamental cellular mechanisms.

Scientific highlights
It gives me great pleasure to outline here a few of the Institute’s most exciting discoveries of the year. A major strength of NIMR
is the way in which structural biology informs our understanding of infectious disease. Influenza remains an important focus of the
Institute, and the significance of this work was emphasized by the news, at the end of 2011, that just five mutations in H5N1 bird
flu might allow it to be transmissible between humans through the air. This observation highlights the importance of the WHO
Influenza Centre at NIMR, which monitors genetic changes in circulating influenza viruses. And while it is very unlikely indeed
that such a virus should appear, the work also emphasises the need to develop therapeutic agents that will block all influenza
virus infections (including swine flu, bird flu and Spanish flu) and could be stockpiled for use in emergencies. One such reagent,
a neutralising monoclonal antibody that confers protection to mice and ferrets, has now been characterised by John Skehel
and Steve Gamblin together with colleagues from Switzerland. An understanding of the structural basis of protection will be
extraordinarily valuable in helping design broad-spectrum vaccines.
Another example of structural biology informing the struggle against infectious disease
comes from work by Ian Taylor, Luiz Pedro de Carvalho and Jonathan Stoye. They
characterised the structure of SAMHD1, a restriction factor which inhibits the growth
of HIV-1, the causative agent of AIDS. Normally expressed in dendritic and other
myeloid immune cells, SAMHD1 prevents reverse transcription of the HIV-1 genome
and inhibits its replication. Further study of SAMHDI will help develop new therapeutic
approaches to HIV-1 and even vaccine development.
Rob Wilkinson and colleagues have found that vitamin D deficiency is extremely
common in black Africans living in Cape Town, South Africa, and is associated

supplementation might be a cost-effective, safe and simple means to reduce the
incidence of TB in South Africa and elsewhere in the world. Work on malaria at NIMR has also continued apace, with new
insights into the way in which the malaria parasite invades red blood cells. Tony Holder and his colleagues have demonstrated that
the malaria parasite can select from a panel of ligands to bind to receptors on the surface of host red blood cells, and this will
probably confound attempts to block invasion that are based on any single ligand receptor.
Gitta Stockinger’s group, with her colleague Marc Veldhoen (now at the Babraham Institute), has discovered that nutrients found in
vegetables such as broccoli and Brussels sprouts activate the aryl hydrocarbon receptor, which helps maintain intestinal epithelial
cells and prevents adverse effects of pathogenic gut micro-organisms. Gitta has also studied the cytokine interleukin-9 (IL-9),
which has been implicated in lung inflammation. By making a mouse in which IL-9-expressing cells carry a stable genetic mark, she
has discovered that during an inflammatory response this cytokine is activated transiently by a subpopulation of innate lymphoid
cells. Those cells go on to express IL-13 and IL-5, cytokines that are normally expressed in the Th2 subset of T cells and which
are a major cause of allergic reactions. Blocking IL-9 reduced IL-13 and IL-5, suggesting that innate lymphoid cells represent an
important link in the regulation of Th2 responses.
Cell marking techniques have also proved important in the area of neuroscience and developmental biology, where Iris Salecker
has devised a genetic multi-colour cell labelling approach for Drosophila that she calls Flybow. Extending work by Josh Sanes
and Jeff Lichtman at Harvard University, this technique allows workers simultaneously to visualise neurons or other cell types, in
defined tissues and at defined times, through the stochastic expression of four membrane-tethered fluorescent reporters. This
will prove to be a remarkably powerful technique to follow the behaviour of cells as they divide, migrate and interact with each
other during development. Alex Gould’s group has investigated the mechanism by which the brain is spared in periods of nutrient
deprivation during human gestation. They also found that the Drosophila brain is protected from the effects of dietary restriction
and that this occurs because the receptor Anaplastic Lymphoma Kinase switches stem cells in the brain from a state where they
require nutrients to grow to one where they do not. This discovery establishes a new genetic model for human intra-uterine
growth restriction, and will shed light on how the mother’s diet influences health and disease in later life.

Brain sparing in the late-stage Drosophila larva
Important insights into how progenitor cell proliferation is regulated in the developing vertebrate brain have come from François
Guillemot and colleagues, who studied a proneural transcription factor, Ascl1, known to be essential for neuronal differentiation.
A genome-wide analysis of transcriptional targets of Ascl1 unexpectedly found that these include genes that control cell cycle
progression. Furthermore, since inactivation of Ascl1 was found to alter the proliferation of neural progenitor cells, this proneural
factor contributes to the expansion of progenitor cell number as well as to their differentiation.
Jean-Paul Vincent, with Eugenia Piddini (now at the Gurdon Institute in Cambridge), has studied how Wnt signalling determines
whether a cell will live or die. Previous work had indicated that cells require Wnt signalling in order to survive. Jean-Paul and
Eugenia found that what really matters is the relative level of Wnt signalling. For example, if a normal cell is surrounded by cells in
which the Wnt signalling pathway is hyperactive, that cell will die. This might be relevant to human cancers in which Wnt signalling
is overactive, perhaps due to mutations in genes such as APC (the most common mutation in colon cancer).
In another technical advance, this time in the mouse, Troy Margrie and his colleagues have shown that the whole-cell patch clamp
method can be used to transfect single cells with plasmids during neuronal recording in vivo. This allowed Troy to record the
synaptic input and sensory function of a neuron and then to trace the upstream brain circuits, but the potential of the method
goes beyond this to include genetic perturbation of intracellular signalling pathways, the introduction of light-activatable ion
channels, and many other possibilities. This approach represents a major step forward in our attempts to understand the functional
architecture of the brain.

PhD students
The training of students, of 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 internationally
competitive. Fully integrated into the NIMR PhD programme are medical
undergraduate (MB BS) students who join us in January of 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 that span multiple research themes, providing them with
an excellent opportunity to broaden their general understanding of science and
acquire practical expertise. As a result of this, our 80 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 and whose role is to advise the student for
the duration of their PhD studies. Initially registered for an MPhil degree, students
transfer to a PhD registration in Year 2 on the basis of an upgrade report. 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 that are
available to PhDs.
Donna Brown
Director of Studies
We encourage a good work-life balance and onsite you’ll find a range of social activities including football, fitness classes, squash,
badminton, a book club, quizzes and a licensed bar. Our student representatives (see page 15) 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 on-site accommodation for 12 students.
Exciting times lie ahead with the opening of The Francis Crick Institute in 2015. The students we recruit from 2012 will move to
The Crick when it opens and plans are already in place to ensure a smooth transition. Until then NIMR students will benefit from
our close relationship with our partner in The Crick, the CRUK London Research Institute.

The 2011 intake of PhD students
Student representatives
With a varied intake of PhD, MBPhD, Summer and Sandwich year students
throughout the year the student representatives aim to inspire a sense of
community amongst the student body through regular social activities. Weekly
student seminars and monthly journal clubs 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. Additionally a Student Seminar Day is
held each year in association with students based at UCL offering a further
opportunity for students to present their work. The student representatives
also sit on various committees within both the NIMR and UCL so that their
opinions can be voiced.
The 2011 student representatives:
Sam Goldsmith, Laura Robinson and Kat Collins.
The 2011 Travel Prize
Each year NIMR awards a £1000 Travel Prize for the best Upgrade Report.
This year the judges were so impressed by all of the reports they decided
to introduce a runner-up prize of a £100 Amazon voucher. The prizes
were presented by Steve Gamblin (Director of Research) to the winner,
Jeff Cloutier (Stem Cell Biology and Developmental Genetics) and the
runner up, Elizabeth Underwood (Molecular Structure).

PhD students – in their own words
Christine Tshitenge
“I’ve been at NIMR for almost three years as a Marie Curie PhD student. My research
project focuses on characterising the differences in immunopathology in virulent
and avirulent P. chabaudi infection. The ultimate aim is to identify differences in the
host immune responses that correlate with disease outcome. This could hopefully
provide useful information for vaccine development and also more insight into disease
pathogenesis. I came to do my PhD here for various reasons. Amongst these are
that NIMR has some of the top and most referenced labs in the world, national and
international collaborations, a culture of learning and carrying out challenging research,
the opportunity to be mentored by some of the world’s leading scientists and to
interact with them on a daily basis. I could say a mouthful of adjectives to describe my
experiences at NIMR, but what I will say is that NIMR has given me an edge in terms of
future career aspirations.”

“Over the past two years, I have been working with James Turner in the Division of Stem
Cell Biology and Developmental Genetics at NIMR. Before coming here, I undertook
my undergraduate education at Middlebury College, Vermont (USA), where I had my
first taste of meiosis research. After attending a Gordon Conference on Meiosis, where
I learned about James’ interesting research, I was inspired to pursue my PhD research
in the UK. My work in the Turner lab has been focused on understanding the molecular
mechanisms that lead to germ cell loss and infertility in mice.
NIMR is a unique place for research. The tightknit nature of the community encourages
frequent interactions, both in the laboratory and in the canteen, corridors and onsite
bar. As a PhD student, I have also had the opportunity to present my work at two big
international meetings. My PhD training at NIMR has been a stimulating and exciting
experience. Over the next two years, I will complete my PhD work at the National
Institutes of Health (USA), as part of a collaborative training programme funded by an
NIH Marshall Scholarship.”

Sandwich students and work experience
Sandwich placements
Now, more so than ever, 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 lab for 12 months and to work
on an independent research project. Sandwich students also have
access to a wide range of lectures, seminars 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 and other leading
research institutions.
Work experience for school students
The 2011 intake of sandwich students
We encourage students from an early age and each year local school students work alongside our researchers, quite often PhD
students, for periods of up to six weeks (also see Research Summer School on page 29). Many of these students come back as
undergraduate, Summer or Sandwich students.

“I was based in Dr Ian Taylor’s lab within the Division of Molecular Structure. My project
focused on a retroviral protein known as Foamy Virus Gag. During the project I obtained
numerous skills including protein production, purification and crystallisation along with
other analytical techniques. I am happy to say that the project was very successful and
resulted in the determination of a Foamy Virus Gag crystal structure. I found the NIMR
a great place to socialise outside of the lab thanks to facilities such as the onsite bar,
monthly social events and weekly sporting activities. The subsidised canteen and Costa
coffee shop were very reasonably priced and made living in London much more affordable.
Overall this year at NIMR has strengthened my desire to work in research and as a result I
aim to study for a PhD after I graduate.”
Rebecca Campion
“This year I spent six months doing work experience at NIMR before going to Cambridge
University to study Natural Sciences (Biological). I spent three months each in two different
laboratories. In all honesty, I have not the words to express how much I learnt and
enjoyed my experience. Although I was exceedingly naive, lacking in both experience and
knowledge, everyone I met took time to answer any and all questions that I had (and there
were many of them). Not only were they incredibly patient, but also everyone I met at the
Institute made me feel welcome. For anyone who is willing and eager to learn I can think of
no better place for student research studies.”

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 development 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 MRC Career Development Fellowships (CDFs).
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. 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 postdocs working at NIMR in different fields and was created to organise, inform and
support the community of postdocs at NIMR. The Committee promotes communication between postdocs, runs a postdoc
website, and has organised a seminar series, exclusively dedicated to and attended by postdocs of the Institute, which has featured
high calibre presentations. The Committee has representation on a number of Institute committees. Finally, it organises the annual
Postdoc Retreat, which, this year, took place at the Natural History Museum. This was a resounding success with interesting
scientific speakers as well as career-focussed presentations and networking. In the coming year the Committee aims to continue
with current activities as well as increasing the communication between postdocs at NIMR and those at institutions that will also
move into The Francis Crick Institute.

Postdoctoral scientists – in their own words
Laurent Dupays, Division of Developmental Biology
“Working at NIMR has been a great experience over the past few years. The
large size of the Institute and the wide range of expertise available allow any
researcher to find what he or she needs in a matter of hours, whether it be
an unusual restriction enzyme or the answer to an obscure statistical problem.
One of the many assets is the incredibly well organised network of services.
As a developmental biologist working on mouse heart development it’s great
to have access to such a wonderful mouse facility. Our animal technicians
are dedicated to taking care of our mouse colonies, which allows us as
researchers to spend more time at the bench furthering our knowledge. And
the mouse facility is just one part of the many dedicated services provided for
scientists at the Institute.
Another benefit is the number of people working on so many different model
organisms. Maybe your speciality is mouse embryology, but you would like to perform some quick functional analyses in an alternative
model? Just go next door and ask about zebrafish or Xenopus embryos and you can expand your project into another organism
within the week. And colleagues are always happy to help you ‘see the light’ by using their preferred model! Without doubt the great
infrastructure combined with the sharing of knowledge and skills makes NIMR a wonderful place to work efficiently, and perform well.”
Otto Kyrieleis, Division of Molecular Structure
“I started at NIMR in November 2009. I am working in Steve Smerdon’s
group, on the structural biology of complexes involved in ubiquitin-regulated
signalling events following double-stranded DNA breaks. I have always enjoyed
the friendly, collegial atmosphere at the Institute and in particular in the
Division of Molecular Structure. In addition to the great working atmosphere
here, the Institute offers a great variety of facilities available for everyone in
the Institute. This allows you to learn many additional techniques and methods
to tackle biological questions. Each facility is run by competent and friendly
staff, who are willing to share their knowledge and expertise with you and to
support you. This makes the life of postdocs at NIMR a lot easier compared
to other institutions. And finally, I really appreciate the opportunities for social
networking at NIMR including the onsite bar, various sport pitches, squash
court and the seminar series such as the Mill Hill Lectures and the bi-monthly
postdoc seminar series with a beer session afterwards. Taking all these things
together this makes the NIMR a very inspiring and exciting place to work.”

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.
Eva Frickel, Parasitology - joined NIMR in 2011
“The reason I am at NIMR is simple. I have always chosen scientific topics and projects
I found most interesting, in the places that I thought did them best. I wanted to start
my own small research group aiming to make a difference in my area of research with
a multi-disciplinary approach. I knew that this would only work in a highly collaborative
environment with research groups around me interested in similar aspects of infectious
diseases, others working with similar methods, all embedded in an institute with fantastic
core facilities and support staff. NIMR immediately stood out as a unique place that
provides all of this.
I applied for a Wellcome Trust Career Development Award to be able to take my research
to Mill Hill. I found an NIMR sponsor in Jean Langhorne, who was enthusiastic to recruit
me to the Institute. NIMR welcomed me with open arms and I am convinced I made the
right choice. I am looking forward to starting my independent career at this place of great
history and innovation.”
Peter Thorpe, Stem Cell Biology and Developmental Genetics joined NIMR in 2011
“I was looking to establish my own laboratory exploring how yeast can be used
to understand adult stem cell function. Many institutions focus their research into
narrowly-defined themes. Finding an environment that bridged basic science and
clinical research was difficult. Although some larger universities achieve this balance,
researchers are naturally divided into either clinical or basic research and often have
limited contact or appreciation of each other’s work. I had seen how the MRC brings
together scientists working at both ends of the basic–clinical science spectrum and so
when I saw an opportunity to work at NIMR, I applied immediately. NIMR’s research is
legendary and with so many great scientists launching their careers here, this was too
good an opportunity to miss.
At NIMR the MRC support means we can spend most of our time on research. We
are able to drive the research forward using new approaches to solve our scientific
questions. The friendly and welcoming atmosphere helps to make interdisciplinary
research a reality. I have already been working with both structural and developmental
biologists to exploit our yeast system in new ways. In the coming years I hope to be
able to make the most of this fantastic environment.”

Troy Margrie, Neurophysiology - joined NIMR in 2009
“As a graduate student in Australia I discovered NIMR through my reading
of several key studies on synaptic transmission and plasticity that were
carried out here. Later, one of my PhD advisors collaborated with Tim
Bliss who visited our lab to carry out in vivo experiments. This exposure
to whole animal electrophysiology seeded my long-standing interest in
systems neuroscience. When I later heard of positions opening up at
NIMR it immediately caught my interest as a very exciting, collegial and
interdisciplinary environment.
NIMR differs from the other institutes I have worked in in two ways.
Firstly, the Lab Managers make a genuine difference; they have all been
outstanding in their ability and attitude. From sorting out hand towels to
redesigning lab space, they work with minimal fuss and as efficiently as
possible. Secondly, the open-door policy and generosity that permeates the
Institute is apparent from the students and postdocs through to Programme Leaders and the Directors and their support teams. There is
genuine altruism and, most importantly, a sense that the science comes first. These two main points have stood out for me and underlie
the very positive psychology that exists here. I think this is also the main challenge for NIMR and its staff moving forward to The Crick.
It is really not about bricks and mortar or the logistics of moving mice and microscopes but rather how one creates such a unique and
positive scientific culture within a reincarnation of NIMR and its co-founding partners.”
Iris Salecker, Molecular Neurobiology - joined NIMR in 2001
“After completing my postdoctoral training in California at UCLA I came
to NIMR to set up my first independent research group. Over the years,
I experienced a truly supportive environment that allowed me to grow
into the role of a PI and develop a long-term research programme, first
as a career-track and then as a tenured Programme Leader. Within the
Developmental Biology/Neurosciences community and beyond, our shared
activities, such as internal seminar series, not only expose us continuously
to outstanding research in a wide range of different research areas, but
importantly also create a genuine spirit of collegiality. Thus, I found both real
mentorship and inspiring colleagues with whom to exchange advice and
expertise and to venture into new territories, such as imaging techniques,
which may not have felt reachable otherwise. I also value that by running
a relatively small group and because of core funding and solely voluntary
teaching, I can work even as a PI, whenever possible, at the bench or in
my case in the fly room or at the confocal microscope side-by-side with
my students and postdocs to test ideas and share the excitement of
advancing our research.”

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, for example the biggest of which, 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.
Alessandra Gaiba, Laboratory Manager
“I started my scientific career with a six-month placement at Glaxo Wellcome in
Stevenage straight after my degree from the University of Bologna in Italy. I decided
to stay in the UK where there were more possibilities to do research outside
academia than there were in Italy. I then spent 13 years working as a medicinal
chemist at SmithKline Beecham (which then became GSK).
A couple of years ago, I decided to change career and came to NIMR as a
Laboratory Manager. For 18 months I shadowed other Lab Managers and covered
for them while they were on holiday, which gave me the opportunity to get to know
all the different areas and all the key people in the Institute. From the beginning, I
was struck by how different the atmosphere was at NIMR compared to industry and
how much easier it was to talk to people. Since July 2011, I have taken on the role
of Lab Manager for the Divisions of Immune Cell Biology and Molecular Immunology,
following the retirement of Nick Clark. So far, I have really enjoyed my new role. I
love interacting with other support staff and my scientists, helping them sort out
problems with equipment, ordering from suppliers and coordinating lab refurbishments.”
Vangelis Christodoulou, Protein Expression Manager
“After successful stints at EMBL-Hamburg Outstation, University of Athens and the
Netherlands Cancer Institute, I came to NIMR (nearly three years ago) with the rather
daunting task to set-up the Protein Expression Lab within the Division of Molecular
Structure. When I arrived, there was a lab packed with equipment waiting for me.
And thanks to the help and support of my line manager and the members of the
Division I had my lab up and running within a few weeks of my arrival. Since being
at NIMR, I have benefited immensely from the freedom I was given to develop new
protein expression technologies, the close working relationship with the members of my
Division and the collaborative spirit amongst NIMR scientists.
So far, NIMR has been a fantastic place to work, giving me the opportunity to get
involved in challenging projects while generously offering all the necessary resources
and support, which makes the whole process very enjoyable.”

Graham Preece, Flow Cytometry Manager
“Following a decision not to pursue a teaching career I arrived at NIMR on
November 14th 1977 and only really expected to stay a couple of years.
However, NIMR’s invigorating and academically stimulating environment together
with its unique warm and friendly atmosphere, which can only be described as
mildly addictive, got in the way of moving further afield and I have thoroughly
enjoyed an exciting and interesting career spanning 34 years.
I first joined Dr Mike Parkhouse’s lab in the Immunology Division and became
an expert in monoclonal antibody production. Following Mike’s departure in
1990 I moved into Dr Ann Ager’s lab where I spent the next ten years working
on lymphocyte trafficking. When Ann moved to Cardiff in 2000 I was recruited
into the expanding Flow Cytometry labs. The research skills I had gained over
the previous 23 years and in particular the experience I had working with
antibodies, fluorochromes, and flow cytometric methods meant that I was easily able to slot into a very busy lab. In 2010 I successfully
applied for the post of Flow Cytometry Manager. Running the Flow Cytometry labs has given me the opportunity to develop the service
and we are now able to offer a cell sorting service at CL2 and have just taken delivery of a new state-of-the-art analyser.
In summary, NIMR offers a fantastic career opportunity for those who want it. Combining this with the exceptional uniqueness of the
NIMR environment means that my last 34 years here have been an incredible experience. I would recommend it to anyone and I hope
new staff experience the same at The Crick.”
Mike Reilly, Procurement Manager
“I began my career as a Research Technician at the Liverpool School of Tropical Medicine and
moved to NIMR in 2003, continuing as a Research Technician in the Division of Developmental
Biology. The position allowed me to gain experience in laboratory management and to successfully
undertake research projects. Three years ago the opportunity arose to become Procurement
Manager at the Institute after I expressed interest to move out of the laboratory. The transition
into purchasing has been an excellent move for me professionally and personally, with my scientific
background proving to be greatly beneficial. The change allowed me to remain at NIMR, as I wished,
as it is an outstanding place to work, evidenced by the length of service of current staff.
One of the major benefits of working at NIMR, within the MRC, is the commitment to professional
development of its staff. I have been fully supported which has allowed me to complete my first
Chartered Institute of Purchasing and Supply (CIPS) qualification in 2011. This is prominently
recognised in the procurement field and I continue these studies to the next qualification with
sustained support. Finally, another highlight of the year was my football team winning the NIMR

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.
Ola Puchalska-Oosorio, Animal Technician
“I joined NIMR Biological Services two years ago as an Animal Technician. Since the
beginning I was trained on how to take the best care of animals used for medical
research, their welfare and how to handle different species correctly. After a few
months at the Institute I had the opportunity to study the Level 3 CPD course in
Animal Technology, and decided to take it because I felt it could help me to improve
my knowledge in this field. This course has helped me to understand more deeply
the legal and ethical aspects of using animals in medical research, their needs,
welfare and environment. The course has been an important complement to my
practical skills gained at the Institute. Also, I found that the flexibility of the course
allows me to take more time in research and helps me to further analyse the topics
studied.”
Kim Demetriou, Animal Technician
“I initially chose to complete the level 2 CPD course in Animal Technology to
increase my vocational qualifications. As much as I enjoy my job as an Animal
Technician, since starting the course I have begun to view my work as a career
rather than just a job. I believe I have gained confidence in my abilities to control
and handle animals, and I have found that learning more about animal husbandry,
the scientific background and the roles of the support staff, has given me a deeper
understanding of research and the importance of providing a high standard of
animal welfare.”

Support for translation
Eileen Clark
Laboratory-based studies at NIMR underpin the MRC’s mission to improve human health through research. 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 Technology Transfer 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.
A translation club for NIMR scientists promotes collaborations/networks
with MRCT, the pharmaceutical industry, clinician scientists and engineers. It
aims to achieve better translational exploitation of NIMR scientists’ findings,
reagents, methodologies and equipment. It meets two or three times a year
and, in addition to NIMR scientists, involves representatives from key partners
including MRCT and University College London Hospital to discuss new
opportunities for translation and to raise the overall awareness of potential
interesting opportunities. In addition, the club aims to bring in a cross-section of
experts from potential partners as guest speakers on an ad hoc basis to open
up new ideas and ways of thinking. Case studies of previous NIMR successes in
translation have been presented to Programme Leaders at the Institute. The club
aims to establish an informal network of contacts that is readily accessible to
NIMR scientists, in order to help exploit their findings.

Phosphate biosensor
A basic research programme on motility proteins required
a rapid and sensitive way to measure inorganic phosphate,
one product of ATP hydrolysis. This led to a novel approach
- a fluorescent reagentless biosensor. The concept is
straightforward. A protein is used as the biosensor framework
to interact with the target molecule, in this case phosphate,
and is modified by attachment of a fluorescent reporter.
Binding of ligands often results in rapid conformational
changes, and these can be read out by changes in the
fluorescent reporter. A phosphate binding protein was chosen
and a fluorophore was attached to this framework to provide
the signal in response to phosphate binding. The resulting
adduct has a millisecond response time and can measure submicromolar concentrations of phosphate.
Although originally designed for a particular project, the
widespread study of phosphatases, ATPases and GTPases
mean that this is a general tool and led to patent protection
by the MRC, licensing to companies and eventually the
availability of the biosensor commercially. The experience and
design principles of this biosensor have also led to a number
of related developments. Several biosensors using similar
principles were developed at NIMR, including ones for ADP
and GDP, which have now been patented.

Mouse House
NIMR Animal Technicians led the work to develop a proven
enrichment device that has significantly enhanced the
welfare of laboratory mice - the Mouse House - which was
patented by the MRC and is now marketed by Techniplast
UK. Over 200,000 Mouse Houses have been sold worldwide.
The transparent red is of a specific wavelength that the
mice see as dark grey. Thus when inside the Mouse House,
mice feel secure while Technicians can still see in to carry
out routine checks and husbandry. Studies have shown that
the mouse house helps to reduce aggression and improves
breeding performance, which is especially important in
transgenic mouse strains. The designers of the Mouse House
were awarded the 2002 ‘Animal Welfare Award’ by the
Swiss Society for Laboratory Animal Science, the first nonacademic recipients of this prestigious award.

Clinical Research
Infectious diseases continue to blight human health worldwide. Our laboratory-based research on diseases such as influenza,
malaria, and tuberculosis (TB) benefits from and informs clinical practice worldwide.
Influenza
The NIMR WHO Collaborating Centre for Reference and Research on Influenza is part of the global surveillance system and is
one of six collaborating centres that assesses the antigenic and genetic characteristics of influenza viruses from around the world.
These centres help to advise WHO and formulate the twice-yearly WHO recommendations for the composition of seasonal
influenza vaccines (see page 54). The six collaborating centres also advise WHO on the emergence of drug-resistant viruses and
on the pandemic potential of animal influenza viruses that can cause infections of humans. By harnessing the power of molecular
and structural biology with virology, the antigenic properties and drug susceptibility of circulating human influenza viruses can be
dissected and the pandemic potential of animal influenza viruses assessed.
Malaria
The Childhood Malaria Research Group (CMRG) has been established as a
partnership between the Division of Parasitology (Fernandez-Reyes and Holder
groups) and the College of Medicine, University of Ibadan, University College
Hospital (COMUI-UCH) in Ibadan, Nigeria. This collaboration brings together
superb clinical skills and hospital infrastructure for the management of severe
malaria with the molecular expertise of NIMR in the densely populated city of
Ibadan, where malaria is among the most common causes of death in children
under the age of five. Nigeria has an estimated one quarter of all malaria cases
worldwide. Our research on the molecular basis of cerebral malaria and severe
malaria anaemia benefits from the close alignment with clinical specialists and
provides a laboratory research capability close to patient point of care. Our
research has already defined molecular markers that predict disease progression
to severity and have the potential to be developed into clinically useful tools for
disease prognosis and clinical management.
Tuberculosis and HIV-TB coinfection
Waiting at the Children’s Outpatient Clinic, University
College Hospital, Ibadan, Nigeria.
Close clinical ties in South Africa (the Wilkinson group at the University of Cape Town) and London have allowed an international
team of basic researchers, clinicians and bioinformaticians, led by Anne O’Garra, to identify a transcriptional signature in the
blood of active TB patients that is missing in the majority of asymptomatic latent and healthy individuals. This signature of active
tuberculosis correlates with the extent of lung radiographic disease and is diminished upon treatment, thus offering potential
biomarkers for diagnosis and treatment monitoring. This is much needed in tuberculosis, which is difficult to diagnose and still
causes 1.7 million deaths per year.

Hirschsprung’s disease
The pathogenesis of Hirschsprung’s disease (the most frequent congenital abnormality of gut peristalsis) is studied by the Pachnis
group in collaboration with clinicians at the UCL Institute of Child Health, Great Ormond Street Hospital. Together the groups
are developing methods to isolate and characterise enteric neural stem cells from human gut tissue, and establishing experimental
systems to assess their ability to colonise aganglionic gut. Having shown in a model system at NIMR that enteric glial cells function
as facultative neural stem cells, the two groups are now studying how the neurogenic potential of human enteric glial cells can be
activated to generate functional enteric neurons in Hirschsprung’s disease patients.
The image depicts groups of enteric neurons and the network of their axonal processes. These neurons fail to develop in
parts of the colon of Hirschsprung’s disease patients.
Disorders of sexual development
The Lovell-Badge group, together with clinical collaborators, has found that chromosome rearrangements around the SOX3
gene are a frequent cause of human XX male sex reversal. This finding followed work in mice where they found that ectopic
expression of Sox3 in the early gonad gives XX males, with Sox3 mimicking the Y-linked testis determining gene, Sry. This work has
important implications for diagnosis in the clinic.

the core techniques of modern molecular biology and biochemistry. The course starts with a half-day induction in molecular
biology, lab skills, safety and record-keeping. Students produce excellent posters and reports of their work, to be shown at events
organised by the Nuffield Foundation. Teachers tell us that bursary holders are a vivid advertisement for the Summer School and
they inspire the next generation of science students to follow the same route. Some of our earlier cohorts of students are now

• Meiosis: The crucial stage in chromosomal physiology that makes genetic re-assortment possible
• Recent progress in molecular biology
• How vertebrates make their limbs; new methods of studying gene function
• The origins of allergy and autoimmunity
• New ways of studying tuberculosis
Once again the speakers found exactly the right level with sufficient novel material to interest teachers but not too far removed
from the curriculum. The lively discussion and written responses afterwards suggest the event was a great success.
Direct involvement in schools
NIMR staff participate directly in science education in the Science Ambassadors scheme providing a distinctive enrichment to
complement the normal school curriculum. NIMR staff are asked to give talks about their research or other topics to Year 12

Infection and replication of retroviruses
Lab members: Virginie Boucherit, Harriet Groom, Mirella Nader, Darren Wight
Retroviruses cause severe diseases, including immunodeficiency
and cancer. 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. There has also been much
excitement and controversy recently over the association
of gammaretroviruses, particularly XMRV, with prostate
cancer and chronic fatigue syndrome. Innovative therapeutics
for retroviral diseases will hopefully arise from a better
understanding of how retroviruses reproduce in the cell, how
they interact with host cell factors and how they subvert the
host innate and adaptive immune systems.
We are interested in defining the specific functions of viral
and cellular proteins during the early post-entry stages of
the retroviral life cycle, particularly reverse transcription, viral
trafficking and nuclear entry. We are using mutant viruses that
cannot complete these steps to identify the cellular proteins
involved in these processes and characterise the important
interactions between viral components. One focus of our
studies is the p12 protein from gammaretroviruses that has
an unknown but essential function during the early stages of
viral replication. We have identified multiple functional domains
within this 84 amino acid protein.

Proteases in host cell exit and invasion by the malaria parasite
Lab members: Christine Collins, Sujaan Das, Fiona Hackett, Robert Moon, Maria Penzo, Andrea Ruecker, Robert Stallmach,
Malcolm Strath, Catherine Suarez, Chrislaine Withers-Martinez, Christiaan van Ooij
Malaria causes immense suffering, killing at least one million people each year, and is
a major contributor to poverty. The disease is caused by a single-celled parasite and
spread by mosquitoes. There is no malaria vaccine, and resistance against mainstay
antimalarial drugs is widespread. There is a need to find new ways to treat and
control this devastating disease.
The malaria parasite infects and divides within red blood cells. These eventually
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 red cell, in anticipation
that a better understanding of this will aid the development of much-needed new
antimalarial drugs and a vaccine. We have a particular interest in a family of parasite
enzymes called proteases that regulate release of the parasite from the red blood
cell, and also modify the parasite surface to ‘prime’ the parasite for invasion. We are
investigating the structure, function and regulation of these proteases, and searching
for inhibitory compounds with potential to be developed as antimalarial drugs.

Mycobacterium tuberculosis systems and chemical biology
Lab members: Flora Dix, Gerald Larrouy-Maumus, Gareth Prosser, Sonia Pedreno Lopez, Joao Pedro S. Pisco
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 because of the
complex growth pattern of Mtb, its extreme adaptation
to the host, and because existing therapies are flawed.
Current mycobacterial and anti-mycobacterial research
programmes have clearly not been sufficiently effective at
providing novel therapies that could reverse this trend in
a timely fashion. New approaches and technologies are
urgently needed to avoid a global health catastrophe.
Our recent work has demonstrated that biochemistry
and bio-analytical chemistry can lead to better
understanding of phenotypes and targets, and to
the rational design and study of new small molecule
therapeutics. We will continue to apply metabolomic
approaches in combination with classic biochemical
and microbiological methods to discover new reactions
and pathways in Mtb that are essential for its survival
and successful infection of human macrophages. In
addition, we will continue our efforts on rational design,
characterisation and testing of new antibiotic candidates
that might be used in the near future as alternative
treatment options for multidrug resistant tuberculosis.

Human papillomavirus biology and disease
Lab members: Cinzia Borgogna, Clare Davy, Heather Griffin, Deborah Jackson, Pauline McIntosh, Emilio Pagliarulo, Yasmina Soneji,
Christina Untersperger, Qian Wang, Zhonglin Wu.
Human papillomaviruses (HPV) cause a range of significant
human diseases, including laryngeal papillomatosis, genital warts
and cervical neoplasia. 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.
Central to understanding papillomavirus-associated disease are
model systems, which allow us to examine in the laboratory
how the virus disrupts the normal growth and differentiation
of the epithelial cells that it infects. Using such approaches,
we can study the initial events during lesion formation, the
mechanism of disease resolution and viral persistence, and
how viral latency and re-activation might be mediated. In our
group, such studies are supported by strong links with clinical
laboratories, and by appropriate molecular studies which look
at viral protein function and the cellular pathways that they
disrupt in order to support the normal or de-regulated virus
life cycle. Our work is ultimately driven by the need to better
understand HPV disease and how to limit its impact.

Pathogenesis of childhood severe malaria
Lab members: Samuel Abah, Dimitrios Athanasakis, Florence Burte, Ianina Conte, Barry Ely, Juho Rousu, Olugbemiro Sodeinde
Half of the world population is at risk of malaria. Human
malaria caused by Plasmodium falciparum represents a global
disease burden with an estimated 300 million clinical episodes
per year leading to around one million deaths. Cerebral malaria
and severe malarial anaemia are both major complications
with significant mortality and morbidity in children under
five years of age in Sub-Saharan Africa. We are focused on
the study of severe malaria syndromes in children attending
tertiary hospitals in densely populated holoendemic malaria
areas. Malaria pathogenesis caused by the parasite’s asexual
erythrocytic cycle largely occurs in the vascular compartment.
We are interested in both the role of endothelial cell activation
and the plasma proteome changes that occur during distinct
severe malaria presentations.
We carried out a large case-control plasma proteome
study of childhood severe malaria, including discovery and
validation cohorts, at the main tertiary hospital of the city of
Ibadan, Nigeria under the auspices of the Childhood Malaria
Research Group. Our clinical proteomics study shows that
plasma proteome profiles accurately discriminate severe
childhood malaria from uncomplicated cases as well as from
ill and healthy malaria-negative children. The defined plasma
proteome patterns are composed of a combination of several
differentially-expressed proteins that act as biomarkers of the
severe malaria disease process.

A new perspective on anti-Toxoplasma gondii immunity
Lab members: Clemence Foltz, Anna Sanecka-Duin, Nadia Shabbir
The protozoan parasite Toxoplasma gondii infects a broad range of hosts, with a
seroprevalence in man of about 30%. Toxoplasma maintains the intricate balance
between survival and host defence. IFNγ, the main cytokine responsible for its
control, activates cells to restrict intracellular parasite replication or to kill intracellular
Toxoplasma. Cell-mediated immunity, driven mostly by CD8 T cells, confers resistance
to the chronic phase of the parasite. The outcome of an infection with Toxoplasma
is determined not only by the host’s immune status, but also by the genotype of the
infecting strain. Toxoplasma pathogenesis results from parasite burden, concurrent with
an over-stimulation of the immune system in the form of high levels of T helper cell
type 1 cytokines.
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 antigen processing
is facilitated for presentation to CD8 T cells. 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 antigenspecific CD8 T cells in the chronic phase of infection in the brain.

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 the posttranslational modification of proteins associated with
the parasite’s actomyosin-based motor that drives the
invasion of erythrocytes. Some of these proteins are
positioned at the right place in the cell by attaching
them to membranes, for example by N-myristoylation
or S-palmitoylation, which adds a C14-fatty acid to the
N-terminal glycine or a C16-fatty acid to a cysteine
residue, respectively. These and other proteins are
also modified by phosphorylation, a process that may
provide a way to regulate the motor. Together with
colleagues in MRC Technology and elsewhere we are
developing inhibitors of the enzymes that carry out these
modifications, to investigate their role in parasite biology
and their potential for therapeutic development.

Antiviral immunity
Lab members: : Urszula Eksmond, Micol Ferro, Dorothy Ng, Mickaël Ploquin, Lara Sellés, Georgina Thorborn, George Young
Viral infections represent a major challenge to the immune system. 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.
Production of antiviral antibodies relies on cognate interaction between B cells and
CD4+ T helper (Th) cells. However, in addition to providing help to B cells, Th cells
are assigned with a range of additional tasks, including direct antiviral activity, and may
also mediate immune pathology. Using a model for retrovirus-induced leukaemia, we
found that interaction with B cells dramatically inhibits the function of virus-specific
Th cells. Ultimately, provision of help to B cells protects hosts from Th cell-mediated
immune pathology, at the detriment of Th cell-mediated protective immunity. Our
findings suggest that B cell presentation of vaccine antigens could be manipulated to
direct the appropriate Th cell response.

The major focus of our group is to understand the immune
response to the malaria parasite and the role it plays in the
development of severe malaria disease. Part of this work
is the identification of the key components of innate and
adaptive immunity that control and eliminate parasites, and
regulate immunopathology. Another 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 have identified a multigene family, cir, in the rodent malaria,
Plasmodium chabaudi, that codes for antigens expressed on
infected erythrocytes. These proteins are recognised by the
immune system and many different CIRs can be expressed
during infection suggesting a role in antigenic variation. Since
variant antigens of the human pathogen Plasmodium falciparum
also adhere to host endothelium, and thus contribute to
pathology of severe malaria, we are investigating whether CIRs
have a similar function. P. chabaudi erythrocytes do sequester in
different organs, and we are now evaluating the role of CIR in
cytoadherence.

The innate immune response of mammals is the first line of
defence to infection by pathogenic micro-organisms, such
as viruses, bacteria, fungi and parasites. This is triggered by
pathogen interaction with receptors on the surface and in the
cytoplasm of neutrophils and macrophages. These specialised
immune cells then produce proteins called chemokines and
cytokines, which attract other immune cells to the site of
infection, including T lymphocytes. Together, these stimulate
the adaptive immune response, which eliminates the invading
pathogen by generation of antibodies and cytotoxic cells.
We study a signalling pathway that regulates the production
of cytokines by macrophages in innate immune responses,
which is regulated by TPL-2, a protein kinase. Our current
experiments are investigating the mechanism by which TPL-2
is activated, and evaluating the potential of TPL-2 as an antiinflammatory drug target in autoimmune diseases.

Host specificity of influenza viruses
Lab members: Michael Bennett, Donald Benton, Nicole Friedrich, Saira Hussain, Ana Luisa Reis, Steve Wharton, Haixia Xiao
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 (N1-9) 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, but additional factors following entry of virus into the cell also control the outcome of
infection. Recent human H3N2 viruses show unexpected receptor-binding activities. The characteristics of this binding 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 is effective in eradicating pathogens via many mechanisms,
including soluble mediators called cytokines. Immune cells can produce different
cytokines to control infection, but can also mediate host damage if uncontrolled.
We are researching the molecular mechanisms for the development and function
of discrete subsets of immune cells producing different cytokines protective against
pathogens, and the induction and function of a regulatory cytokine, IL-10 produced
by many cell types. We will build on our past results, using biochemical methods
and genome-wide, high-throughput approaches and bioinformatics, to elucidate the
molecular mechanisms for induction of IL-10 production and function in different
immune cell types.
We continue to examine mechanisms of IL-10 production and function in chronic
MTb infection. Leading on from our findings in human TB, where we identified
a robust blood transcriptional interferon-inducible signature, we will investigate
potential factors in TB pathogenesis, such as Type I IFNs and Type I IFN-inducible
genes, using 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.

Regulation of T cell homeostasis by antigen receptor signals and cytokines
Lab members: Thea Hogan, Daniel Marshall, Ina Schim van der Loeff, Ana Silva, Charles Sinclair, Sim Tung, Louise Webb
T lymphocytes are immune cells that play a central role in regulating immune
responses. There are several different T cell types, all with different functions. Having
the right number and composition of T cells is therefore essential for a normal
immune system. The production and maintenance of these cells is strictly controlled
by mechanisms regulating cell survival and proliferation. Cellular signals transduced by
the T cell antigen receptor (TCR) and from cytokines such as IL-7 play a central role
in regulating homeostasis of T cells.
TCR and IL-7 signalling are both essential for regulating survival and homeostatic
proliferation of T cells. Whether there is any interaction between these signals is
controversial. We have recently uncovered a novel mechanism by which TCR and IL-7
signalling interact to control T cell homeostasis. We found that IL-7R expression by
mature T cells critically depends on TCR signals received during their development
in the thymus. This TCR signal dependent mechanism ensures that the best T cells
generated during positive selection have a survival advantage that preferentially
maintains them in the peripheral repertoire.
Induction of a tetracycline-inducible Zap70 transgene restores thymocyte
development in Zap70-deficient mice.
Controlling Zap70
expression in vivo reveals
how TCR signalling tunes
IL-7R expression during
development and maturation
of newly generated CD4 T
cell in the thymus.
A single dose of inducer results in a pulse of Zap70
protein expression in thymocytes that is sufficient to
start development of CD4 T cells.

Our current focus is on the development and function
of innate and adaptive IL-17 producing T cells (Th17
cells), and modulation of effector functions by exogenous
and endogenous environmental factors. Th17 cells are
important for defence against fungal pathogens and
many extracellular bacteria, and are causally involved
in autoimmune diseases such as rheumatoid arthritis,
myocarditis, multiple sclerosis and psoriasis.
We developed an IL-17A fate reporter model, which
allows us to study development of IL-17 producing
T cells and their behaviour during infection in vivo. We
furthermore 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.

Retrovirus-host interactions
Lab members: Vicky Felton, Seti Grambas, Wilson Li, Sadayuki Okura, Martha Sanz-Ramos, Melvyn Yap
Comparative genome analysis suggests that vertebrates and
retroviruses have co-existed for tens of millions of years. It is thus
unsurprising that a degree of co-evolution 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.
The host proteins TRIM5a and Fv1 typify such defence factors.
They interact with incoming viruses, shortly after viral entry into
the cell cytoplasm, binding to the viral core and inhibiting reverse
transcription or nuclear transport. To help study this interaction we
have isolated a number of viral mutants that escape from restriction
by the different factors and used them to delineate the region of
capsid recognised by Fv1 and TRIM5α. These studies implicate the
whole surface of the viral core in factor binding.

Activation of immune receptors
Lab members: Antonio Casal, Jason Lee, Elizabeth Natkanski
Antibodies are critical for human immunity and their
induction has been instrumental for the success of many
vaccines. 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 receptors (BCRs). The BCR is a protein
complex containing the membrane form of antibody and two
signalling components; we are characterising the structure of this
complex to gain insights into the mechanisms by which antigen
binding activates the BCR. We are also developing new ways
to visualise the activation and endocytosis of BCR molecules in
living B cells.

B and T lymphocytes are white blood cells that are critical mediators of the immune
response against a variety of pathogens. 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. We have shown that proteins called
Rac GTPases are critical for controlling the migration of both B and T cells into,
through, and out of lymph nodes. Currently we are studying signals that control B cell
homeostasis.
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. We are mapping the location of dosage-sensitive genes that cause
Down syndrome phenotypes using chromosome engineering techniques.

Immune response to influenza
Lab members: Stefania Crotta, Sophia Davidson, Gregory Ellis, Annita Gjoka
Seasonal influenza represents a constant burden to public health, and
influenza pandemics caused by 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
also contributes to lung pathology. In addition to direct damage, influenza
infection also increases dramatically the susceptibility to bacterial coinfections, as evidenced by epidemiological and microbiological data from
seasonal and pandemic influenza waves. Both for single infections and coinfections, it is unclear which factors tip the balance between pathology
and/or death, versus successful clearance of the pathogen without long
term damage.
Our work aims to identify virus and host 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
use primary airway epithelial cells to determine which recognition systems
are used to detect viral infection and how this information is transmitted
to the immune system. The role of interferon-driven feedback systems
in infection is studied in this system and in vivo, to understand the role
of interferons in anti-influenza immune responses. We also investigate
the roles of natural killer cells and granulocytes in influenza infection and
co-infection. These studies will allow us to link early events to subsequent
immune-mediated pathology or protection.

We have contributed to the description of a distinct transcriptomic

vitamin D deficiency is highly prevalent amongst black Africans in Cape

Regulation of Th2 cells during allergic inflammation and anti-helminth immunity
Lab members: : Stephanie Coomes, Stephanie Czieso, Nicholas Mathioudakis, Isobel Okoye, Victoria Pelly
More than a quarter of the world’s population are infected by one of
four parasitic helminths (filarial worms, schistosomes, whipworms and
roundworms) making them the most common infectious agents of
humans in developing countries. Efficient expulsion of parasitic helminths
from mammalian hosts requires a well-orchestrated immune response to
activate innate immune cells and stimulate local tissue responses. CD4+ T
helper 2 (Th2) lymphocytes coordinate the expulsion mechanism, placing
them front and centre of anti-helminth immunity. One major aim of our
work is to develop ways to promote Th2 cell responses and enhance
anti-helminth immunity. An additional and complementary aim is to
investigate ways to inhibit Th2 cell responses to remedy allergic disease.
Allergic diseases plague hundreds of millions of people worldwide and
are the result of dysregulated and hyper-active Th2 responses.
These aims are being investigated using in vivo helminth infection and
allergy models. Using next-generation sequencing and gene manipulation
techniques the roles of regulatory RNA species in Th2 cells and
associated responses are being studied. De novo immune responses
develop, often in tandem with other ongoing immune responses.
Therefore, in collaboration with other NIMR programmes, we are
investigating the mechanisms of Th2 cell development and function in
the context of other immune responses. Together these aims will extend
our knowledge of Th2 immunobiology, facilitate helminth elimination
strategies, and identify novel interventions for allergic disease.

One third of the global population is exposed to infection with
Mycobacterium tuberculosis but only ten percent of individuals
will develop tuberculosis. 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 136 WHO National Influenza
Centres (NICs) form the WHO Global Influenza Surveillance and Response System (GISRS) to track influenza viruses as
they circulate around the world. Viruses are characterised antigenically (genetically) in the laboratories and their resistance to
antiviral drugs is determined. Results of these analyses from each collaborating centre and the national centres 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 influenza circulation.
Research has focused on recent H3N2 viruses that show alterations in their ability to bind to sialic acid receptors. Many H3N2
virus strains agglutinate red blood cells through their neuraminidase glycoprotein, which has marked implications for the antigenic
analysis of these viruses. All our studies are carried out with the NICs from around the world, with other WHO Collaborating
Centres, the UK Health Protection Agency, the National Institute for Biological Standards and Control, and members of the
European Community Network of Reference Laboratories for human influenza, and the Wellcome Trust Sanger Institute.

Secretory organelle formation, trafficking and exocytosis
Lab members: Emma Cookson, Jennifer Frampton, Nicola Hellen, Nikolai Kiskin, Laura Knipe
One of the ways in which cells sense and respond to their environment is through
the cell surface expression of integral membrane proteins (e.g. hormone receptors,
ion channels, adhesion molecules, etc.) and the secretion of soluble molecules into the
external environment (e.g. hormones, transmitters, morphogens). The correct delivery
of such molecules to the cell surface or extracellular space involves the secretory
pathway. We study the secretory pathway in order to understand the processes that
underlie the formation, trafficking and exocytosis of regulated secretory organelles,
the post-Golgi membrane bound containers that store and deliver proteins to the cell
surface/exterior in response to external signals. We use endothelial cells (ECs) and
the Weibel-Palade body (WPB) as our model system.
P-selectin is stored in WPBs and delivered to the EC surface following WPB
exocytosis where it functions to facilitate leukocyte attachment and rolling. FRAP
analysis of P-selectin in individual WPBs revealed that its enrichment within the
organelle arises from its immobilisation within the WPB membrane through an
interaction between its extracellular domain and the paracrystalline assembly of
Proregion-VWF tubules within the WPB lumen. Dissolution of Proregion-VWF
tubules during WPB exocytosis releases P-selectin allowing its diffusive delivery into
the plasma membrane.

Nuclear magnetic resonance (NMR) spectroscopy provides a valuable
means to probe the three-dimensional structure, dynamic characteristics
and binding properties of biological molecules, large and small. Our group
employs state-of-the-art methods in NMR to investigate the nature of
interactions between proteins implicated in fundamental cellular and
organismal processes. These include the activation of death receptor
signalling cascades, limb regeneration in the adult newt model, the
regulation of phospholipase C isozymes, the role of β2-glycoprotein 1
in antiphospholipid syndrome and the interaction of vascular endothelial
growth factor (VEGF) with its receptors.
Recently we have applied a combination of heteronuclear NMR,
microcalorimetry and small-angle X-ray scattering (SAXS) to dissect
the overall 3D structure and impact of phosphotyrosine peptide ligandbinding on the multi-domain ‘specific array’ component of the second
messenger enzyme phospholipase C γ1 (PLCγ1). With these data we
have developed a model of the mechanism for the enzyme’s activation.
In other work we have established a method to analyse small molecule
metabolites in Drosophila fruitfly samples by NMR. We used this approach
to contribute accurate measurements of larval hemolymph amino acid
concentrations in a study of brain sparing under conditions of nutrient
withdrawal.

Modelling the evolution of molecular components, systems, and behaviours
Lab members: Martin Godany, Kyriakos Kentzoglanakis, Bhavin Khatri, Asif Tamuri, Grant Thiltgen
All biology is the result of evolution. 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. We also use more theoretical models to better
understand how the evolution of proteins determined
their observed properties. We study the evolution of
viruses such as influenza in order to better 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 model the evolution of chemotaxis, the process that
allows bacteria to find nutrients, providing insight into the
evolution of biochemical networks. We are also studying
how horizontal gene transfer affects the evolution of
bacteria, especially where the interests of the genes and
the organisms conflict, and where the transferred genes
encode social behaviour.

Structure and function of G protein-coupled receptors
Lab members : Carol Curtis
Living cells are delimited by a membrane which isolates
their internal machinery from the external world.
However cells such as the neurons which form the
information-transduction networks of the brain must
still be able to respond to incoming chemical signals. The
7-transmembrane helix G protein-coupled receptors
(GPCRs) are a superfamily of genetically-encoded
nanomachines that have evolved to enable this. Since
GPCRs are the targets of about 40% of clinically prescribed
drugs, a detailed understanding of their structures and
molecular mechanisms of action is essential to underpin
programs of selective drug development.
M1 muscarinic acetylcholine receptors (M1 mAChRs)
regulate the activity of many output neurons in the
forebrain. They are important mediators of cue detection
and memory. Drugs that selectively activate M1 mAChRs
are targeted at the cognitive defects in Alzheimer’s disease
and schizophrenia. We can isolate stable ligand complexes
of M1 mAChRs, combining pharmacological and protein
engineering methods. We are focusing on a highly-selective
peptide toxin, MT7, which binds to M1 with very high
affinity, working towards an atomic resolution structure by
X-ray crystallography. Such structures provide a firm basis
for the resurgent area of rational drug design.

total internal reflection fluorescence microscopy (TIRFM)
allow us to observe, track and manipulate individual

health, including how the malarial parasite gains entry into

signals in the heart, and how the two strands of DNA are
separated and copied.
Recently, we have used Atomic Force Microscopy (AFM)
to visualise ataxin-3 fibrils, which are the causative agent of

are unexpectedly flexible; consistent with their structure
being composed of “beads on a string”. Using a simple in vitro
assay consisting of just actin, myosin and ATP, we found that
actin filaments become aligned and form ordered domains.
We are now using a combination of mathematical modelling
and experiment to understand this simple system and test

Synthetic protein laboratory: acyl transfer for chemical biology and synthesis
Lab members: Lotta Holm, Geoffrey Knight, Caroline Morris, George Papageorgiou
One of the most important recent developments in chemistry has been the
emergence of biologically compatible ligation reactions. These reactions can be used
to synthesize small proteins and introduce non-natural modifications to label proteins.
Chemical ligation is usually dependent on the presence of cysteine at the ligation
junction. However by simple modification of the terminus of a peptide we can modify
it into a mimic of cysteine. This expands the flexibility of the synthesis so that we can
cut and paste proteins and reassemble them from their component peptides.
The focus of the group is to expand the utility of ligation reactions and to look
for possible existing biological roles for these elegant chemical reactions. The
demand for site-specifically modified proteins for structural studies or fluorescent
labelling of proteins in cells is driving the further development of these techniques.
We are applying chemical ligation to the synthesis of chemically defined peptideoligosaccharide vaccines and to activity based proteomics as well as the total
synthesis of homogenous post-translationally modified proteins and self-assembling
systems.

Understanding the molecular bases of neurodegeneration
Lab members: Salvatore Adinolfi, Cesira de Chiara, Serena Faggiano, Clara Iannuzzi, John McCormick, Laura Masino, Raj Menon, Kris
Pauwels, Domenico Sanfelice, Robert Yan
We are interested in a molecular understanding of
neurodegenerative diseases. To achieve this, we study the structure,
fold stability, and function of proteins involved in diseases using
different but complementary biophysical, biochemical and systems
biology approaches. We mainly focus on neurodegenerative
processes caused by misfolding and/or mitochondrial dysfunction.
Over the last year we made substantial advances in elucidating
the primary function of frataxin, the protein associated with
Friedreich’s ataxia. We conclusively showed that frataxin binds
to NFS1/IscS, the desulphurase central to iron-sulphur cluster
formation. As a result, frataxin enhances the affinity of NFS1/IscS
with the ISU/IscU scaffold protein and regulates rates of cluster
formation. By identifying the regions that determine fibrillogenesis
of ataxin-3, the protein responsible for Machado-Joseph disease,
we have also shown that normal function and aberrant protein
aggregation, as observed in several neurodegenerative diseases,
are competing pathways. This result is of primary importance
for understanding misfolding diseases and suggests that specific
therapeutic interventions can only be achieved by studying normal
function and pathology in parallel.

Molecular recognition in post-transcriptional regulation

Post-transcriptional control plays a key role in expanding
genomic diversity in complex organisms, and de-regulation
of the metabolism of specific mRNAs lies at the basis of
common genetic diseases, cancer, autoimmune pathologies
and viral infection. 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.
Our recent work on the RBM38-p21 system has connected
the RNA recognition properties of the RBM38 protein with
its capability to counteract the miRNA binding activity on
a subset of p53 targets. RBM38 is expressed under cellular
stress and binds selected miRNAs in the proximity of the
miRNA seed sequence, hindering miRNA activity. We show
that the RRM domain of RBM38 selects U/G rich sequences
and explain how this domain discriminates between two
pools of p53 targets creating a further level of downstream
regulation. Our data on the RBM38 system suggest a conduit
to control the activity of a subset of p53 targets associated
with cell replication and human cancers.

Structural biology of signalling networks that regulate innate and adaptive immunity
Lab members: Nicholas Brown, Manuela Hess, Marios Koliopoulos, Aylin Morris-Davies, Rohini Rana, Kovilen Sawmynaden,
Ben Stieglitz, Edmond Wong
Pattern recognition receptors are key components of the innate
immune system that sense microbial and viral infections and
initiate a pro-inflammatory response. The signalling pathways
activated by these receptors need to be tightly controlled as
misregulation can lead to chronic inflammation and autoimmune
disease. Innate immune responses also trigger adaptive immunity
and the two systems are linked through complex signalling
networks.
Our research is focused on the structural characterisation of
protein complexes that regulate innate immunity. In particular,
we are interested in understanding how members of the NLR
(NOD-like receptor) family of intracellular PRRs recognise a
target and relay the signal to elicit a specific cellular response.
The post-translational modification of a protein with ubiquitin
chains is often used as a regulatory signal in immunity. The type
of ubiquitin chain attached to a target protein determines the
physiological outcome of the modification, with K48-linked chains
targeting a protein for degradation while K63 and M1-linked
(“linear”) chains play an important role in signalling. We aim to
elucidate, on a structural and functional level, the mechanism
by which a specific type of ubiquitin chain is synthesised
and attached to a target by a catalytic cascade involving the
sequential action of three enzymes.

Structural biology of phosphorylation-dependent signalling in the cell cycle and DNA
Lab members: Julie Clapperton, Oliver de Peyer, Mohamed Ismail, Otto Kyrieleis, Richard Li, Jan Lloyd, Simon Pennell, Lasse Stach, Grace Yu
The dynamic nature of cellular signalling processes requires them
to be rapidly reversible, a characteristic that is generally achieved
through protein phosphorylation. 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, Forkheadassociated (FHA), Brca1-C-terminus (BRCT) and Polo-box domains
that function as phosphorylation-dependent adaptors or scaffolding
molecules in Ser/Thr kinase pathways.
Our recent work has shown how FHA and BRCT-repeat domains
of Nbs1 – a component of the MRN DNA damage complex
– work in concert to orchestrate DNA break processing and
signalling to the rest of the repair machinery. In a study of kinase
signalling in M. tuberculosis, we have revealed a role for phosphoindependent FHA interactions and a novel, intra-molecular binding
mechanism in the control of core metabolic processes that likely
have significance for bacterial virulence. Finally, we have resolved
long-standing questions about FHA domain specificity using X-ray
crystallography and molecular dynamics modelling methods.

Macromolecular assemblies
Lab members: Laurence Arnold, Neil Ball, Valerie Ennis-Adeniran, Joe Hedden, Dominic Pollard, Laura Robertson, David Schwefel.
Many of the fundamental processes carried out within living cells are
directed by macromolecular assemblies of protein and nucleic acid
molecules, often referred to as “molecular machines”. 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
and the investigation of the retroviral capsid, together with proteins
that mediate retroviral restriction in host cells. Recently, we have
determined the structure of the HIV-1 restriction factor SAMHD1.
This study has revealed the molecular details of the mechanism of
SAMHD1 catalysis and provides an explanation for how this protein
can inhibit HIV-1 infection of myeloid-derived cells.

Protein structure analysis and design

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 defines
their uniqueness, but more typically as a compact threedimensional 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.
With the rapid increase in the volume of sequence data,
we have re-examined residue contacts predicted from
correlated positions in a multiple sequence alignment.
In collaboration with colleagues in computer science at
UCL, we have developed new methods to extract these
contacts and applied them to protein structure prediction.
The contacts are often sparse and uncertain but, to some
extent, these limitations in the data can be overcome by
grouping the contacts by secondary structure elements and
enumerating the possible packing arrangements of these
elements in a combinatorial manner. Strong interactions
appear frequently but inconsistent interactions are downweighted and missing interactions up-weighted. The
resulting improved consistency in the predicted interactions
has allowed the method to be successfully applied to
proteins up to 200 residues in length, which is larger than
any structure previously predicted using sequence data
alone.

The molecular mechanisms of motor proteins
Lab members: Claudia Arbore, Lori Callum, Liisa Chisty, Colin Davis, Simone Kunzelmann, Gordon Reid, Lesley Southerden
Movement of proteins along DNA is an essential feature of cells: it
occurs during DNA replication and repair, for example. Helicases are
enzymes responsible for separating the two strands of DNA, making
them available for processing by other enzymes. We are interested
in both the mechanism and control of such processes. We are
developing new optical approaches, such as reagentless biosensors, to
study the proteins and nucleic acids during this process of movement
along DNA. In addition such reagentless biosensors provide a way to
assay a wide range of enzymatic activities.
Our work on helicases is focussed on developing a complete
system in which the helicase interacts with other proteins as well as
moving through DNA. We are investigating the replication of certain
plasmids that contain antibiotic resistance genes and that are readily
transferred between bacteria. Such replicating plasmids contain a
specific double-stranded origin of replication, and are bound with a
replication initiation factor (RepD), a helicase and polymerase. We are
currently working on building up this system in vitro to study the role
and mechanism of each component in this system. The development
of biosensors has included one for ADP or GDP, which has a high
specificity and has properties that make it suitable for real-time assays
and for high-throughput approaches.

Neuronal subtype specification in the midbrain and hypothalamus
Lab members: Neal Anthwal, Lan Chen, Suzanne Claxton, Martin Levesque, Wei Lin, Emmanouil Metzakopian, Anna Truckenbrodt
The mammalian midbrain and hypothalamus contain many types of
neurons that regulate voluntary movement and energy homeostasis,
respectively. How the different types of neurons are generated
and are wired into functional circuits remains a central question in
developmental neurobiology. We study how neural progenitors in
the brain give rise to midbrain dopaminergic (mDA) neurons and
hypothalamic neurons involved in regulating feeding. Our findings
have direct medical relevance, since loss of mDA neurons is the
hallmark of Parkinson’s disease, and dysfunction of feeding circuits in
the brain can lead to obesity in humans.
We use mouse embryos and in vitro differentiation of mouse
embryonic stem cells to identify genes that regulate the
specification, proliferation and differentiation of mDA, arcuate
proopiomelanocortin and neuropeptide Y neurons. Our studies
employ a combination of embryological, genetic, molecular, genomic
and proteomic approaches, including genetic fate mapping studies,
phenotyping null and conditional mutant mice, brain explants, timelapse imaging, chromatin immunoprecipitation, biochemical and
transcriptome analyses. These studies provide important insights
into how embryonic gene expression leads to mature neuronal
phenotypes. We are also interested in the role of transcription
factors in maintaining neurotransmitter phenotypes and function in
adult neurons.

Regulation of growth and metabolism

Rita Sousa-Nunes, Irina Stefana
All organisms regulate their growth according to internal genetic programmes
and the availability of nutrients from the environment. 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,
obesity and diabetes.
Currently, we are investigating how dietary nutrients regulate the embryonic and
foetal growth of each body organ. Much of our research in this area uses the fruit
fly Drosophila, a model organism that shares many genes with mammals. We recently
showed that neural stem cells in the Drosophila brain need to be kick started by
amino acids early on in development but, thereafter, they can grow and divide without
dietary nutrients. This reflects a switch in neural stem cells from Insulin-like Receptor
to Anaplastic Lymphoma Kinase signalling. Anaplastic Lymphoma Kinase lies at the
heart of a molecular network ensuring that the growth of the developing brain is
spared over that of the body when nutrients become limiting.
The Drosophila CNS escapes growth shutdown during nutrient restriction.

Cristina Minieri, Emilie Pacary, Noelia Urban, Debbie Van Den Berg, Benny Yang
Neural stem cells in the developing brain produce a vast array
of neurons that reach specific positions where they integrate
into functional circuits. This process of neurogenesis involves
the progression of neuronal precursors through a succession
of cellular steps of proliferation, migration and differentiation.
We study the genetic programmes that regulate and coordinate
these different steps in the embryonic and adult mouse brain,
using genomic approaches to identify the genetic pathways
involved, and functional assays to determine the contribution of
individual genes to the different steps of neurogenesis.
We recently found that the proneural transcription factor
Ascl1, well known for its role of promoting neurogenesis in the
embryo, also controls the division of neural stem cells during
development and in the adult brain. We are now studying the
molecular pathways that regulate the transcription and protein
stability of Ascl1 during adult neurogenesis, as disruption of
these pathways in the ageing brain might be responsible for
the reduction of neurogenesis and the accompanying cognitive
decline observed in old animals.

Lab members: Ed Bracey, Alex Brown, Ninja Grewe, Bruno Pichler, Ede Rancz, Mateo Velez-Fort
The benefit of detecting and recognising information in the
external world has been a key driver of the evolution of
the central nervous system. The neuronal basis of sensory
representation in our brains therefore underpins how we
make sense of the world around us, our ability to solve
problems and remember past experiences. Our lab is focused
on understanding the fundamental cellular and network-based
mechanisms that underlie these processes.
The goal of our lab is to understand how the brain uses the
activity of individual neurons and collections of neurons to
encode sensory stimuli. To achieve this we use a top-down,
multidisciplinary approach that allows us to explore this key
issue from the systems to the cellular level. Specifically, we are
investigating several questions: (i) To what extent is sensory
representation distributed across primary and secondary or
multimodal brain areas? (ii) What, if any, is the relationship
between local neuronal connectivity and sensory function?
(iii) How is sensory information encoded and integrated by
individual cells and synapses?

The nervous system mediates the interaction of organisms
with their environment, contributes to the maintenance of
internal homeostasis and is the anatomical substrate of cognitive
activity. 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.

Visual circuit assembly in Drosophila
Lab members: Holger Apitz, Dafni Hadjieconomou, Emily Richardson, Benjamin Richier, Nana Shimosako, Katarina Timofeev
The ability of animals to perform the many tasks of their
everyday lives relies on the perfect functioning of their
nervous systems. These consist of a large number of
neuronal and glial subtypes with strikingly diverse shapes.
Our understanding of the molecular mechanisms that
control the formation of these cell types and coordinate
their assembly into functional neural networks during
development is still limited. To address this issue, we use the
visual system of the fruit fly Drosophila as a genetic model,
because it enables us to study the stepwise development of
a complex neural circuit with single cell resolution.
In particular, we are investigating the mechanisms that
control (i) the development of specific neuronal and glial
cell subtypes in higher visual information processing areas,
(ii) the targeting of one colour-sensitive photoreceptor axon
subtype to its temporary and final synaptic layers, and (iii)
layer-specific targeting of dendritic and axonal branches of
partner neurons. To facilitate the imaging of the underlying
interdependent cellular interactions, we recently generated
a multicolour cell-labelling approach for Drosophila, called
Flybow. By studying the mechanisms underlying normal
brain development, we hope in the long term to contribute
to the understanding of neurological disorders that may be
linked to early connectivity defects.
In the larval optic lobe of Drosophila, progenitors (blue) in the outer and

Regulation of boundary formation and neurogenesis
Lab members: Marie Breau, Sean Constable, Sebastian Gerety, Andrew Georgiou, Lauren Gregory, Mohamed Ismail, Rosie Morley,

During the early stages of nervous system development in
vertebrates, neural tissue is subdivided into regions, each with
a distinct identity. Within these subdivisions, the differentiation
of progenitor cells is regulated in time and space to form the
correct organisation of specific neuronal and glial cell types.
In order for precise patterns to form and be maintained, it is
essential that sharp borders form at the interface of the distinct
regions.
Our studies aim to elucidate molecular mechanisms of boundary
formation and neuronal cell differentiation, and the links between
these processes in the formation of the segmented pattern
of the vertebrate hindbrain. We are using a combination of in
vitro assays, in vivo functional studies and computer modelling to
understand how signalling through Eph receptors and ephrins
leads to the formation of sharp borders. In related work, we
study how hindbrain boundaries, together with signalling from
specific neurons, organise discrete zones of progenitor cells and
neuronal differentiation. Finally, we are dissecting the mechanisms
of action of an intracellular network that regulates neural stem
cell maintenance and differentiation. These studies utilise the
powerful genetic and transgenic tools available in the zebrafish
model for analysis of gene function and in vivo imaging of cell
migration and lineage.

Pattern formation in the vertebrate nervous system
Lab members: Fahad Al Saud, Natascha Bushati, Rachel Chung, Michael Cohen, Katrina Griffin, John Jacob, Anna Kicheva, Eva Kutejova, Steven Moore, Noriaki Sasai
We study how the central nervous system (CNS) is formed in embryos. 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 pattern formation in the neural tube. In ventral regions of the caudal neural tube,
the secreted molecule Sonic Hedgehog (Shh) forms an extracellular gradient that
governs pattern formation and tissue growth. 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.
A reporter of Shh signalling (top panels; green in bottom panels) provides a

The Y chromosome and infertility
Lab members: Fanny Decarpentrie, Shantha Mahadevaiah, Obah Ojarikre, Áine Rattigan, Nadege Vernet
The first evidence that the mammalian Y chromosome carried genetic information essential
for male fertility was obtained in 1976 for man, and 1986 for mouse, from the study of
individuals with partially deleted Y chromosomes. Evidence that the Y chromosome is
incompatible with female fertility comes from studies of XY individuals that have a deletion
removing the male determinant SRY.
We have been using sex chromosomally variant mouse models in combination with the
selective addition of Y genes by transgenesis to elucidate the role of specific Y genes in male
and female fertility. Using this approach we, together with the Turner group, have identified
important quality control functions during spermatogenesis for the Y-encoded genes Zfy1
and Zfy2. These genes encode zinc finger transcription factors that proved to be necessary
for the apoptotic elimination of sex chromosomally aberrant pachytene spermatocytes in
response to a failure of Y chromosome silencing, and during the first meiotic metaphase in
response to the presence of an unpaired X chromosome.
Sxra encompasses18 genes from the mouse Y chromosome, including the testis
determinant Sry. XO carrier males (XSxraO) are sterile because spermatocytes
are eliminated by apoptosis during the first meiotic division.
With the reduced Y gene complement of Sxrb plus Eif2s3y
(spermatogonial proliferation factor), or Sry and Eif2s3y, there is no
apoptotic response; this is reinstated by the addition of Zfy2.

Regulation of eukaryotic chromosome metabolism
Lab members: Jesus Carballo and Ana Penedos
Genome duplication and segregation are two fundamental
processes in biology. We study the ways in which signal
transduction regulates these events. A key component in
eukaryotic chromosome metabolism is the ATR/ATM family
kinases. These evolutionarily conserved signal transduction proteins
play a key role in many fundamental DNA/chromosomal processes
such as genome duplication, recombination, and checkpoint
regulation. Inactivation of ATR/ATM in humans leads to cell death,
genome instability, and meiotic dysfunction as well as the genetic
disorders, Ataxia Telangiectasia and Seckle syndrome.
We use genetically tractable S. cerevisiae to study the molecular
basis for ATR/ATM function. We found that inactivation of Mec1/
Tel1, the budding yeast homologues of ATR/ATM, leads to
chromosome breakage during proliferation and disruption of
essential meiotic chromosomal processes. Our research focuses on
elucidating the molecular mechanism(s) by which the loss of Mec1/
Tel1 function leads to these defects.

Regulation of early vertebrate development
Lab members: Dilrini DeSilva, Joseph Grice, Stefan Pauls, Paul Piccinelli, Hannah Stanforth
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, interestingly, 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.

Gene regulatory networks in early development
Lab members: Brook Cooper, Nick Owens
Embryonic development is a complex and tightly controlled process, with
a remarkably precise outcome. The underlying control system is only
partly understood. 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.
We are focusing on the period in the development of the early embryo
when control passes from maternal gene products, to those derived from
activation of gene transcription in the growing embryo. This maternal-zygotic
transition marks a profound watershed in the growth of the embryo as
it becomes reliant on the integrity of its own genetic material. Using the
Xenopus model system, we have taken a high resolution time series of whole
embryo mRNA samples through this transition period and analysed these
for gene expression levels using high-throughput Illumina RNA-seq technology. In order to understand our data better, we have
been taking a close look at intrinsic variation in gene activity, by studying biological replicates. This has enabled us to build a robust
method for detecting signatures of gene activation, and this is a first step in the process of reconstructing the gene regulatory
networks involved in early development.

Understanding vertebrate limb development
Lab members: Sorrel Bickley, Natalie Bufferfield, Martin Carkett, Veronique Duboc, Anna Kucharska, Sue Miller, Satoko Nishimoto
Limb defects are the second most common congenital
abnormality present in human live births and diseases affecting
the musculoskeletal system are a significant clinical problem in
the older population. The goal of our work is to understand
how the limbs normally form during embryogenesis, the genesis
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 skeletal scaffold via the correct tendon. How this complex
is elaborated is poorly understood.
We are using animal models to understand the mechanisms that
control limb bud formation and the subsequent construction of
the individual limb elements.

Sex, stem cells and decisions of cell fate
Lab members: Sarah Booth, Christophe Galichet, Sam Goldsmith, Silvana Guioli, Ander Matheu, Adam Nunn, Helen O’Neill, Karine
Rizzoti, Charlotte Scott, Ryohei Sekido, Clare Wise
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 impact on cell fate
choices, and how they might be exploited to aid treatments for clinical problems, such as stroke and cancer.

Heart development in vertebrates
Lab members: Mike Bennett, Laurent Dupays, Surendra Kotecha, Marianne Neary, Izabela 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, we will gain a better
understanding of the origins of cardiac malformations and a
model of how complex organs are formed in the developing
embryo.
We are using 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 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.
In this tadpole, muscle cells of the heart, head and body can be readily
visualised through expression of a fluorescent reporter, providing a simple
way to monitor heart development.

Liver development in zebrafish
Lab members: Johanna Fischer, Jordi Cayuso Mas, Despina Stamataki
The liver represents the largest internal organ, performing a
plethora of essential functions to maintain body homeostasis.
During embryogenesis, the liver, pancreas and lung originate from
adjacent domains of the foregut. A well-orchestrated programme
of developmental steps ensures the functional differentiation of each
organ, starting with the precise allocation of multipotent foregutendoderm to a particular organ fate. Central aims of our research
are to understand how liver progenitors are specified from the
foregut endoderm and how these committed precursors rearrange
to shape the functional liver. We investigate these questions using
the experimental advantages of zebrafish.
Using genetic approaches, we found that two Wnt ligands regulate
specification and subsequent proliferation of liver progenitors.
Importantly, Wnt levels need to be tightly controlled within the
embryo, since excess expression of either ligand promotes liver
formation at the expense of the pancreas. Our current work
aims to determine the interactions of Wnt signalling with other
pathways controlling liver formation to unravel the molecular
network directing underlying liver specification from the pool of
multipotential progenitors. The identification of organ-specific
genetic programmes will provide insights into not only the
mechanisms regulating embryonic development, but also tissue
homeostasis and regeneration following injury in adults.

The molecular basis of mesoderm formation
Lab members: Camille Bouissou, Clara Collart, Kevin Dingwell, Alex Eve, Tiago Faial, George Gentsch, Elsie Place, Thom Spruce,
Anna Strobl, Alex Watson, Mary Wu
The different cell types of the body are formed in the right
place and at the right time in response to signals produced
by special organiser regions of the embryo. These signals,
or morphogens, act in a concentration-dependent manner
to induce the formation of 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 formation of the mesoderm as well as that of the
neural crest.
We use frog, zebrafish and mouse embryos 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 in the
embryo, and biochemical and mathematical approaches
to ask how cells distinguish between different morphogen
concentrations. We also use sophisticated molecular
techniques to elucidate 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, we hope our work will assist in
efforts to direct stem cells down desired developmental
pathways.

Systems microscopy studies of cell fate determination
Lab members: Erika Aquino, Eva Herrero, Elena Ledesma and Guðjón Ólafsson
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.
Using these tools, we aim to identify the conserved
mechanisms controlling asymmetric division, lineage
specification and mitotic spindle function.
Yeast arrayed at high-density allow large-scale screening of mutants for their
effect upon the kinetochore. This reverse genetics approach identifies genes
that regulate kinetochore function, particularly asymmetry of cell division.

X chromosome inactivation, meiotic silencing and infertility
Lab members: Jeff Cloutier, Jennifer Grant, Grzegorz Polikiewicz, Helene Royo, Mahesh Sangrithi
In mammals, X chromosome inactivation (XCI) occurs in all cells
in the female and in developing germ cells in the male. In females,
XCI serves to equalise X-dosage with males. The role of XCI in
male germ cells is unclear. We study the mechanisms underlying
both forms of XCI and the influence of XCI on the gene content
of the X chromosome.
We have shown that XCI in male germ cells is essential for fertility.
This study has also allowed us to ascertain that misexpression of
the gene pair, Zfy1/2, is the underlying cause of sterility in XYY
males. We have found that the X chromosome is highly enriched
in genes involved in sperm differentiation, with around 20% of all
genes on the X chromosome being expressed only in male germ
cells. Many of these genes are likely to be important for normal
male fertility. In female eutherian, or ‘placental’ mammals, XCI is
mediated by the non-coding RNA Xist, but how XCI is controlled
in the other major class of mammals, the metatherians, is
unknown. We have now discovered that the epigenetics of XCI in
metatherians is similar to that of eutherians, raising the possibility
that XCI in metatherians is mediated by an as yet unidentified
non-coding RNA.
In XYY males, pairing allows the two Y chromosomes to escape
inactivation by gH2AX and to express Y-genes; the resulting
expression of the toxic Zfy1/2 genes leads to germ cell arrest.

A small number of signalling molecules orchestrate growth and cell
fate decisions during development. We investigate the mechanisms
that control the production, spread and activity of one signal,
Wingless (a member of the Wnt family). We also study the regulatory
mechanisms that allow cells to compute their position within the
Wingless gradient. This led us to find that cells with overactive Wnt
signalling eliminate their normal neighbours, a finding that may be
relevant to tumour biology. In a separate, but related strand of
research, we aim to understand the mechanisms that trigger the
elimination of cells following epithelial disruption.
Disruption of epithelial cell adhesion leads to widespread apoptosis,
a phenomenon that likely reflects the need to eliminate cells that
detach from the epithelium, thus preventing them from causing
havoc. As we found recently, Jun kinase (JNK) is a key mediator of this
process. However, how epithelial disruption activates JNK remains to
be discovered. It will also be important to understand why in other
cellular contexts, this pathway does not necessarily trigger apoptosis.
We are using transcriptional profiling, confocal imaging and genetic
analysis to investigate the links between epithelial disruption, JNK
signalling and apoptosis.

Harvesting medical benefits from the human genome depends on understanding
the tasks that specific genes perform in living organisms. Our group studies
gene functions important for initial formation of organs and subsequent disease
processes, by identifying and characterising genetic mutations that profoundly
affect tissue development. Since most gene functions are shared among all
vertebrates, we use the easily-studied externally-developing embryos of a frog
with a simple chromosomal structure, Xenopus tropicalis.
We have used positionally mapped genes underlying a number of mutations,
including several resulting in abnormalities of otoconia, inner ear crystal structures
essential for vestibular/balance function. Study of these mutations may help
understand a common human balance disorder, benign positional vertigo.
Together with collaborators, we have also used solution-hybridisation wholeexome enrichment technology to isolate and sequence the protein-coding space
of X. tropicalis genomes derived from chemically mutagenised stocks. This strategy
has rapidly yielded more than 100 new mutations for further study, and includes
genes that are important for a variety of processes including ciliogenesis, left-right
asymmetry and erythropoiesis.

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.
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 Local Ethical Review Process, 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 approximately
200 new genetically altered rodent lines each year by both transgenic and gene-targeted
technologies. 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.

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. 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 histidine 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 consist of four spectrometers, including one
operating at 800 MHz, a 700 MHz instrument, and two 600 MHz
instruments. Centre staff have a high level of expertise in designing,
implementing, and analysing macromolecular NMR studies. The
spectrometers are suitable for investigating a wide range of biological
systems in solution. Three of the four are equipped with the latest
cryogenically-cooled probes for enhanced sensitivity. The facilities are
currently used by research groups from NIMR and 18 external groups at
universities and institutes from around the UK. Within NIMR our closest
links are with the Division of Molecular Structure.

X-ray crystallography
Protein X-ray crystallography is a technique that produces a three-dimensional model of the structure of a protein at atomic
resolution. 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 which allows the
unattended screening of 80 crystals in a single experiment. Diffracting protein crystals are the culmination of an extensive series
of experimental procedures which include protein purification and protein crystallisation. A range of sophisticated techniques are
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.

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.

Protein sequence analysis and structure modelling
José Saldanha
Computational tools for prediction, analysis and visualisation
can provide inspirational new ways to look at data, no matter
which protein family is the main focus of research. From highlevel predictions of protein topology by template-free methods
(sometimes called ab initio), through three-dimensional all-atom
models of protein structure, to detailed protein-ligand docking
studies; theoretical methods developed both at NIMR and in the
wider academic community can suggest new insights and new
hypotheses leading to the design of fruitful experiments.

A support service for protein sequence analysis and structure
modelling is provided. It draws on state-of-the-art algorithms
being developed by experts in the Division of Mathematical
Biology as well as the many computer programs freely available
from the scientific community. There is also an in-house,
commercial, computer graphics package for detailed threedimensional modelling. The service is available to all NIMR
scientists and external collaborators.
Analytical ultracentrifugation
The Institute has two analytical ultracentrifuges located in
the Division of Physical Biochemistry. These instruments
provide first-principle hydrodynamic and thermodynamic
information concerning the size, shape and association state of
macromolecules. For basic applications, the two instruments
(XL-A and XL-I) are equipped with UV/Vis optics that record
radial absorbance measurements and monitor evolving
(sedimentation velocity) or static (sedimentation equilibrium)
concentration gradients. The XL-I is additionally equipped
with Rayleigh interference optics that measure concentration
profiles directly from solute refractive index gradients. The
interference and absorbance data are recorded simultaneously
in the XL-I and are used in combination for the analysis of
complex associating systems.
The optical detection system of the XL-I analytical ultracentrifuge consisting
of a combined UV/Vis spectrophotometer and laser interferometer is shown
in the bottom panel. A fringe displacement pattern produced by a moving

four offline workstations, a data storage system, and image processing
software such as Volocity, Imaris, Image J, Metamorph and MatLab.
Currently the facility supports 170 researchers from 16 NIMR 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 super
resolution imaging, correlative microscopy, high-throughput imaging,
automatic cell segmentation and tracking, and others relevant to NIMR
research. The lab has expertise in sample preparation and labelling, live/
fixed sample imaging, and hardware/software development required by
NIMR researchers.

Histology
Radma Mahmood
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 (HE) 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, and
immunohistochemical techniques.

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 102) and Histology (page 103). 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. The freely available data (www.embryoimaging.org)
complement standard anatomical texts and can form the basis for systematic analysis of mutant morphological phenotypes.

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.

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.

studies, including Illumina GAIIx and HiSeq2000 sequencers, the Affymetrix Gene Chip
hybridisation and Illumina iScan Systems.
High-throughput sequencing
High-throughput sequencing technologies are revolutionising molecular genetics, vastly
expanding our ability to study genome structure, how genes are regulated and how cell
and tissue differentiation occurs. Combined with increasingly sophisticated bioinformatics
analysis, these methods of massively parallel sequencing-by-synthesis are likely to impact
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. In order to maintain its position at the
forefront of basic research, NIMR has established a central next-generation sequencing
core facility. The facility currently supports DNA/RNA sequencing using the Illumina
Genome Analyzer IIx (commonly referred to as “Solexa”) for reads up to 150 bases for
both single and paired-end runs. This facility provides a cost-efficient service, producing rapid and highly accurate DNA and RNA
sequence data for researchers at NIMR. By assisting at all stages from experimental design to data assembly and analysis, the
service dramatically extends the ability of our scientists to make discoveries in genomics, epigenomics, gene expression analysis
and protein-nucleic acid interactions. The facility now includes the Illumina HiSeq 2000 sequencer. With innovative design features,
the HiSeq 2000 provides output of up to 200 Gb per run (2 x 100 bp read length), up to 25 Gb per day and two billion paired
end reads/run.

Level 4 high-containment virus laboratory
Within the complex of buildings that make up NIMR is a suite of laboratories for handling viruses with high pathogenic potential
for birds, humans or other mammals. 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, poorly characterised viruses are also received. Some of these viruses, 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.

Nobel Laureates
Five scientists from NIMR have been awarded Nobel Prizes for their scientific research.
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 gasliquid 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-)
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.

Five famous alumni
Brigitte Askonas, FRS (1923-)
Brigitte (Ita) Askonas worked at NIMR from 1952-1989. She was Head of the Division of Immunology
from 1976. She made seminal contributions to our understanding of the molecular basis of lymphocyte
responses to proteins, and especially to infectious agents.
Brigitte Askonas
Philip D’Arcy Hart, CBE (1900-2006)
Philip D’Arcy Hart joined the MRC in 1937, working on dust diseases in coal miners, then moved to the
MRC Tuberculosis Research Unit until he retired in 1965. In 1948 he ran the first controlled clinical trial,
to show the efficacy of streptomycin against tuberculosis. A later trial led to the introduction of BCG
vaccination in the UK. After he retired he moved to NIMR with an MRC research grant, working until 2002.
Philip D’Arcy Hart
Robert Edwards, CBE, FRS (1925-)
Robert Edwards worked at NIMR from 1958-1962. During this time his interests moved from pure
science to biomedicine, and a desire to do something about human infertility. His studies on induced
ovulation and superovulation in mice presaged his later work at Cambridge, with Patrick Steptoe, in which
they applied such approaches to humans, thus bringing about the revolution in in vitro fertilisation. For this
later work he received the Nobel Prize for Physiology or Medicine in 2010.
Robert Edwards
Charles Harington, FRS (1897-1972)
Charles Harington was Director of NIMR from 1942-1962, and oversaw the Institute’s move from
Hampstead to Mill Hill. He was an outstanding biochemist who contributed to our understanding of the
thyroid gland and of the hormones it produces, particularly thyroxine. Another achievement was the
synthesis of glutathione, and he undertook pioneering work in immunochemistry. As Director he strongly
encouraged cooperation between scientists working in different departments.
Charles Harington
James Lovelock, CBE, FRS (1919-)
James Lovelock worked at NIMR from 1941-1961. His most important invention
while at the Institute was the electron capture detector, which was able to detect minute amounts of
chemicals. Originally designed for analytical purposes it was also able to detect industrial pollutants in the
atmosphere, alerting the world to the dangers of unchecked pollution. After leaving NIMR he became an
independent scientist and developed the Gaia Hypothesis.

NIMROD
NIMROD is the NIMR social club. Membership is open to all
staff for a very small annual subscription. 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
