We are interested in how lymphocytes decide to mount immune responses against, for example, tumours. This involves trying to understanding how leukocyte receptors, such as the T-cell receptor and immune checkpoints, are triggered.

These are some of the receptors we're striving to understand...

Our focus has been on the cell biology of the T-cell surface. We developed general methods for crystallizing glycoproteins and determined the structures of key T-cell surface proteins including the first adhesion protein, CD2, and its ligand CD58, the costimulatory receptor CD28 and its ligand CD80, and the large tyrosine phosphatase CD45. We also worked out how weak, specific recognition is achieved by these types of proteins and obtained the first insights into the likely overall composition of the T-cell surface. We also made a significant contribution to a controversy concering the stoichiometric behaviour of G protein-coupled receptors. Most importantly we proposed, with Anton van der Merwe, one of the most complete and best-supported explanations for leukocyte receptor triggering, called the 'kinetic-segregation' (KS) model. We are using the KS model as the basis for developing novel treatments for autoimmunity, with Richard Cornall. Our work is funded principally by The Wellcome Trust, but also by the UK Medical Research Council. Please see http://davislab-oxford.org/ for more details.
