Summary
Multiple Sclerosis (MS) is the most common cause of paralysis in young people. EAE is an animal model of MS that recapitulates many features of the human disease. Recent data shows that EAE is mediated by IL-17 producing self-reactive T cells. NKT cells are a group of T cells, whose activation protects against EAE, in an as yet unidentified manner. These studies will provide critical information on the way in which NKT cells regulate immunity and will enhance development of therapies for MS.
Role Of Inflammation In The Physiological And Pathological Function Of The Gastrointestinal Tract

Summary
The gastrointestinal tract is continuously exposed to the external environment as a consequence of what we ingest. We have therefore evolved distinct mechanisms to deal with exposure to non-pathogenic insults in the gut. Sometimes, however these mechanisms fail leading to chronic inflammation and resultant pathology, which can under certain circumstances develop into cancer. This study will investigate inflammation in the gut, with particular interest in the systems that control inflammation.
The Structural Basis Of T Cell Recognition In The Context Of Lipid Presentation And The CD1 Isoforms

Summary
CD1 molecules are critical in our host-defence against microbial pathogens. They survey our body for microbial lipids and then present them to our immune system for surveillance by T cell receptors. We aim to understand how a T cell receptor interacts with a CD1-lipid molecule. This interaction is crucial to the activation of our immune response and hence the elimination of the microbe. Once understood, this interaction can potentially be modified and has immunotherapeutic potential.
Follicular Helper T Cell Development And Function: From Mechanisms To Application

Summary
Antibodies are the basis of most successful vaccinations. Diminished antibody responses lead to immunodeficiency while excessive antibody responses contribute to autoimmune diseases. We are studying a newly identified specialised helper T cell subset, termed follicular helper T cells, which is essential to regulate the high-affinity and long-lived antibody responses. The knowledge should provide new strategies to design better vaccines, to control infections, or to treat autoimmune disorders.
