T lymphocytes recognize antigenic peptides expressed on the cell surface in association with molecules encoded by the major histocompatibility complex. Recognition of a peptide-class I molecule by a T cell receptor (TCR) expressed on a CD8 T lymphocytes leads to cytokine production and to cytolysis of the presenting cell. Each individual T cell expresses a different TCR. During thymic development, thymocytes are subject to selection based on the binding specificity of their TCR. T cells with a TCR that is of too high or too low an affinity for self MHC molecules are deleted in the thymus. It is estimated that 90-95% of cells that enter the thymus never leave and die in situ. Our lab investigates 2 aspects of T cell development: (1) the contribution of the CD8 molecule to activation of T lymphocytes; (2) the mechanism by which cells that express a TCR that is of too low an affinity for self MHC molecules, die in the thymus.
