Research Focus

T-cell Physiology and Function
T cells arise in the thymus and display responsiveness to peptidic fragments of foreign antigens bound to major histocompatibility complex (MHC) molecules in spleen and lymph nodes. Three aspects of T cell differentiation and function are being examined:


As the result of contact with self peptides and MHC molecules in the thymus, most mature T cells display tolerance to self components. The mechanisms involved in such self tolerance induction are being studied.


Presentation of foreign antigens to mature T cells is controlled by specialized antigen-presenting cells (APC). The events involved in T/APC interactions are being examined with the aid of artificial APC.


Most immune responses culminate in the production of specialized T memory cells. The factors controlling the production and survival of T memory cells are being investigated.
