Farewell to Julian Behr

A big farewell to Julian Behr. Julian has been an amazing Masters student this year. Our first Babraham alumni is now off to start his PhD with Maries van den Broek at the University of Zurich. Expect great things!

Dr Lidia Yshii wins Golden Pipette

Congratulations to Dr Lidia Yshii for winning the 7th Golden Pipette at our joint Leuven-Cambridge lab retreat held at the Babraham.

The most elegant experiment is always a tough call at our lab retreat, but it is hard to go past a simple treatment that blocks 90% of the damage during traumatic brain injury!

Looking forward to accelerating this treatment into the translational space. 

Scientific heroes

My first scientific hero was Sir David Attenborough. From the youngest age, his documentaries guided me into thinking like a scientist. To try to understand life through the prism of evolution, to understand living systems as complex positive and negative feedback loops. David Attenborough inspired me to become a biologist, and shaped my politics and my ethics. I recently wrote to him to thank him for the profound effect he has had on me, and was incredibly pleased to receive a letter from him this week. #tellyourheroes

New horizons for Immunology

by Becky Allen

New group leaders bring new skills, new expertise and new perspectives, and 2018 saw three new group leaders join the Institute’s Immunology programme. Professor Adrian Liston, Dr Claudia Ribeiro de Almeida and Dr Sarah Ross talk about their research, their ambitions and what makes the Institute such a special place to work.

They come from VIB in Belgium, Oxford’s Proudfoot lab and the University of Dundee, they focus on different areas of immunology and bring new interests and expertise, but Professor Adrian Liston, Dr Claudia Ribeiro de Almeida and Dr Sarah Ross are all hugely excited to have recently joined the Institute.

Liston, already an established group leader, works on the specialist population of immune cells known as CD4T cells. These cells effectively coordinate and ‘turbo charge’ our immune response. They are also the cells that are targeted by HIV, explaining why the disease causes immune system suppression and illustrating how crucial CD4T cells are to our overall health.

At VIB, Liston specialised in translational immunology, understanding and then developing ways to treat children with rare immune diseases. “These diseases are incredibly severe, but once you understand them mechanistically you can work out ways to treat them,” he explains. “It was very rewarding because these kids that would otherwise often die can go on to lead long, healthy lives once you’ve found out what’s wrong and how to fix it.”

At the Institute, Liston wants to answer three key questions: how the millions of CD4T cells in our bodies communicate and cooperate; how they switch between a ramping up and damping down cell type; and what they do in our tissues. Understanding how these cells modulate our immune system means that they can potentially be used as a tool to fine tune the immune system to help overcome age-related decline.

With its world-leading Immunology programme and cutting-edge facilities the Institute is a great fit for Liston’s ambitions. But what sets the Institute apart is how it nurtures scientific innovation and champions equality and inclusion.

“Great research requires fantastic people who think as differently as possible, which means having an environment that celebrates equality and inclusion. The Institute has a great reputation for this internationally – it’s setting the gold standard for equality and inclusion. You can feel the difference here,” says Liston. “The Institute provides an environment where you’re going to be stimulated and have the chance to explore the limits of your imagination.”

Ribeiro de Almeida and Ross both believe the Institute’s culture will help them build their first research groups. “It’s a very friendly, supportive environment. Everyone is ready to help with time and feedback – they want you to succeed and that’s really special,” says Ross.

Ribeiro de Almeida’s work centres on B lymphocytes and the rare ability they have to rearrange antibody genes by cutting and pasting DNA in order to fight the plethora of pathogens to which we are exposed. “I’m interested in understanding how this mechanism is regulated throughout cell development,” she explains. “It’s a fundamental question, because mistakes in this process can result in leukaemia and lymphoma. To understand these diseases and wider age-related immune dysfunction it’s important to understand how these molecular mechanisms are regulated.”

As a postdoc in Oxford, she worked in a lab that studied gene expression rather than B cells, so she brings a more molecular approach to the programme. She also discovered an RNA-binding protein that plays an important part in B lymphocytes’ cut and paste process, something she’s keen to follow up: “The research I want to do next is to identify which proteins are implicated in this mechanism of gene rearrangement and how they modulate B cell responses.”

Ross specialises in T lymphocytes and the impact that hypoxia – or low levels of oxygen – has on the way they work. Because T cells commonly encounter hypoxic environments, they can adapt to low oxygen environments by changing the proteins they express. While this helps them survive, it can also make them less effective killers of disease cells.

“I want to understand how oxygen regulates T cells from a signalling and gene expression perspective,” she explains. “If we could identify factors that we could target therapeutically to overcome the effects of low oxygen and boost the ability of T cells to perform their protective function, that would be amazing.”

We know that as we age, our immune system becomes less effective and poorer oxygenation is also connected with ageing, so what Ross discovers about hypoxia could have important implications, both for our understanding of the ageing immune system and in making immunotherapies more successful.

The arrival of all three is an exciting opportunity for the Institute, the Immunology programme and its three new group leaders. “It’s amazing – I’m still pinching myself,” Ross concludes. “It’s great to be able to make new plans and work out how to turn them into reality utilising the know-how and the facilities we have access to here. And it’s exciting to be here because my plans cover all three programmes – Immunology, Signalling and Epigenetics – adding my own to all the expertise here makes it hugely exciting.”

When should I apply for a fellowship?

To develop an academic career in research you need to develop two sides of your CV - one is your publication record and the other is a record of prizes, fellowships and grants. Publications are hard. Years of research and a brutal revision process make accumulating a publication record slow and painful. Prizes, fellowships and grants are, in principle, easier. You write up a proposal and submit. Often you can even submit the same proposal in multiple places. It is very rare that prizes are awarded without you applying for it, so sending out a lot of applications just makes sense.

For poster prizes, departmental awards, travel grants, the equation is quite simple: apply for them. There are a lot of small prizes that are usually under-subscribed, they can earn you a little money and these small prizes build up to greater things. For fellowships, on the other hand, I have started to lean in the other direction. I used to suggest that all post-docs apply for a fellowship - if successful, it is a nice income and a highlight in your CV, and if unsuccessful, well... it is good practice. Now, however, I tend to discourage fellowship applications very early on in the career. Newly graduated PhD students are often very keen to apply for fellowships, and there are so many opportunities that you can easily spend a year applying for one after the other.

The question that you need to ask yourself is whether applying for fellowships is a a good investment of time. A successful fellowship application normally merges a great idea (the science) and a proven record to deliver that idea (most importantly, your publication record). A lot of post-docs make the mistake of applying for fellowships too early, before their publication record is ready to support it. It is easy to think that there is no cost to doing so, but applying for fellowships takes a non-trivial amount of time. As a scientist you always need to weigh up the opportunity cost: time spent on fellowships is time not spent on experiments. There are times when applying for a fellowship is sensible, and other times when you are better off investing all of your energy in experiments (building that publication record for future fellowships). Here are a few factors that you can consider:

Factors that should encourage you to apply for fellowships:

• You are a senior post-doc looking to become independent
• The fellowship allows you to take a key mobility step (eg, Marie Curie to return to Europe)
• You just published a highlight paper
• Your PI says you need a fellowship to stay in the lab (but consider moving labs instead)
• You don't expect your CV to improve in the next year
• You will not be eligible next year

Factors that should discourage you from applying for fellowships:

• Your PI has a grant that covers the full period of your project
• You have a top story cooking (it deserves all your attention!)
• Your publication record is relatively thin, without any highlight papers (but watch out for being excessively self-critical! A neutral faculty member is a useful independent judge)
• You expect your CV to improve in the next year

My suggestion: rather than automatically write a fellowship, because that is what post-docs do, carefully consider the factors above, consult with faculty and then rationally decide where to invest your effort. Make sure that you don't talk yourself out of applying just for reasons of self-confidence, but also don't be afraid to concentrate on the science this year instead of applying, to put yourself in a better position to apply next year.

Golden Pipette won by Dr Wenson Karunakaran

Congratulations to Dr Wenson Karunakaran! 

It was tough competition for the sixth Golden Pipette at the Cambridge-Leuven joint lab retreat. The final prize had to go to Dr Karunakaran for his work on brain CD4 T cells.

Many neuroscientists assume there are no CD4 T cells inside the healthy brain, but there are in fact around 5000 per gram of brain tissue. How do we know? Wenson imaged and counted them, one by one. 

That is what it takes to win the Golden Pipette.

Immune profiling ‘will be a revolution in medicine’

A revolution in medicine is coming.

It could aid the diagnosis of diseases, guide the way patients are treated and inform the discovery of new therapies.

Immune profiling seeks to explain how our body’s own defences are affected by and are responding to disease.

At the Babraham Institute, Professor Adrian Liston is working on the translation of this technique from the laboratory to the clinic.

“The immune profile is much more powerful than genomic data, but it’s much easier to get genomic data,” he tells the Cambridge Independent. “You can take blood, send it overnight and get it sequenced off-site. We are not at that stage with immune system data.

“But the more we know about different diseases, the more we realise there are inflammatory, or immune-mediated, components.

“It can be a revolution in medicine. Once the infrastructure is set up and hospitals are doing the analysis routinely, we will see an explosion in utility. Right now, it’s a research tool only.”

Dokter Algoritme

Algoritmen kunnen inzichten bereiken waar een mens moeilijk toe komt. Computeralgoritmen kunnen almaar beter moeilijke diagnosen stellen, soms zelfs beter dan artsen. Immunologe Erika Van Nieuwenhove van de Leuvense tak aan het Vlaams Instituut voor Biotechnologie (VIB) en haar collega’s melden in Annals of the Rheumatic Diseases dat ze een zelflerend algoritme hebben ontwikkeld dat met bijna 90 procent zekerheid artritis bij kinderen kan vaststellen, louter op basis van een bloedtest.

Het gaat om de vaakst voorkomende vorm van reuma bij kinderen, maar omdat de ernst en de evolutie van de symptomen sterk kunnen variëren, is een diagnose stellen niet altijd gemakkelijk. Het algoritme evalueert alleen de samenstelling van het immuunsysteem van de patiënten. Het zal nuttig zijn om te bepalen welke behandeling aangewezen is.
