PKC Isotype Functions in T Lymphocytes

Conference paper
Part of the Ernst Schering Foundation Symposium Proceedings book series (SCHERING FOUND, volume 2007/3)


The main function of mature T cells is to recognize and respond to foreign antigens by a complex activation process involving differentiation of the resting cell to a proliferating lymphoblast actively secreting immunoregulatory lymphokines or displaying targeted cytotoxicity, ultimately leading to recruitment of other cell types and initiation of an effective immune response. In order to understand the physiology and pathophysiology of T lymphocytes, it is necessary to decode the biochemical processes that integrate signals from antigen, cytokine, integrin and death receptors. The principal upon which our work is based is to explore and identify gene products of distinct members of the AGC family of protein serine/threonine kinases as key players mediating cell growth regulation. Given the established important role of PKC θ as regulator of T cell fate and knowing that several other PKC isotypes are also expressed in T cells at a high level, we now summarize the physiological and non-redundant functions of PKC α, β, δ, , ζ and θ isotypes in T cells. This review describes the current knowledge of the physiological and non-redundant functions of the PKC gene products in T cells.
