Brief description A major role for cytotoxic, or killer, T cells is the recognition and removal of virus infected or tumor cells from a host. Upon recognition of a target host cell, killer T cells deliver a package of proteins, termed granzymes, that mediate the removal of these virus infected and tumor cells. Naive killer T cells need to be activated to start producing these effector molecules. This proposal plans to examine the factors that regulate both induction and maintanence of cell specific expression of these effector molecules. We plan to identify the molecular events that occur within a cells genome to turn on granzyme gene expression and how these factors influence subsequent killer T cell function. The conclusions from these studies will enable us to determine why some killer T cell responses are not effective and what can be done to improve killer T cell function. This has implications for the development of novel vaccine strategies designed to induce immunity against both viral and tumour challenges.
