The cell is the building block of life. This proposal focusses on the surface of the cell, the plasma membrane, and specialised structures called caveolae that are an abundant feature of animal cells. Altered caveolae are a feature of many human disease conditions. In this proposal we will address the function of caveolae. We will test the idea that proteins are released from caveolae into the cell when cells are stressed forming a novel signalling pathway disrupted in disease.

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.
