We are interested in understanding how T lymphocytes communicate with their environment both during differentiation in the thymus and subsequently in the periphery to regulate survival, expansion and further differentiation into effector or memory cells, while maintaining tolerance. In particular we are focussed on the role of the Src-kinase family and their modifiers such as the phosphatase, PTPN22, in facilitating responsiveness to antigens while retaining tolerance to self-proteins.
