Regulation of T cell Apoptosis during the Immune Response
Apoptosis of T-lymphocytes is a fundamental process regulating antigen receptor repertoire selection during T cell maturation and homeostasis of the immune system. It also plays a key role in elimination of autoreactive lymphocytes. Resting mature T cells are activated by antigen to elicit an appropriate immune response. In contrast, preactivated T cells undergo activation-induced cell death (AICD) in response to TCR triggering alone. Thus, death by apoptosis is essential for function, growth and differentiation of T-lymphocytes. This review focuses on apoptosis mechanisms involved in T cell development and during the course of an immune response.

More about this publication?
- Current Molecular Medicine is an interdisciplinary journal focused on providing the readership with current and comprehensive reviews on fundamental molecular mechanisms of disease pathogenesis, the development of molecular-diagnosis and/or novel approaches to rational treatment. The reviews should be of significant interest to basic researchers and clinical investigators in molecular medicine. Periodically the journal will invite guest editors to devote an issue on a basic research area that shows promise to advance our understanding of the molecular mechanism(s) of a disease or has potential for clinical applications.
