Abstract:
:Analyses of the complex regulatory networks leading to T cell survival, death, and immune deficiency have been aided in the past year by the dramatic development of new technologies to identify T cells and assess T cell function. These new techniques have shown that functional inactivation and apoptotic elimination of both virus-specific and non-virus-specific T cell populations mold T cell responses to viral infections.
