The regulation to early T cell signalling is a critical step in immune responses. Superimposed onto the biochemical pathways is a spatial organization that defines the immunological synapse. My research aims to map the principles of the spatial organization on the molecular scale to identify how lipids could unbalance the dynamic signalling equilibrium, for example in obese patients. To achieve this goal, my research group has developed single molecule microscopy approaches.

Summary
An immune response starts with activation of the T cell antigen receptor (TCR). How T cell receptor signalling begins, however, is not well understood. We have developed a novel imaging approach that allows us to directly observe what happens after an antigen binds to the receptor. The research will provide mechanistic insights into how T cells sense and discriminate antigens. This knowledge will aid the development of cancer immunotherapies and vaccines.

Summary
My research will use cutting edge imaging techniques to provide a fundamental advance in our understanding of how foreign viruses and pathogens trigger the immune system. Gaining a greater understanding of these central events will facilitate the design of novel therapies to treat immune associated disorders such as transplant rejection, autoimmune disease and some cancers.

Summary
T cell lymphocytes are essential cells in our immune system. They respond to signals from foreign bodies to mount an immune response. Many diseases arise from errors in their activation processes. The key steps in the translation of the initial arrival of a foreign-body to a T cell into an immune response will be examined in these studies, where we will look at the cooperation of components of the cell membrane during T cell activation. This will help us to understand and treat immune disorders.
