Polyfunctionality of Allospecific Cytotoxic T-Lymphocytes in in vitro Systems

Polyfunctionality of Allospecific Cytotoxic T-Lymphocytes in in vitro Systems The data presented demonstrate the capacity of allospecific cytotoxic lymphocytes to fulfill noncytolytic regulatory functions. Cytotoxic lymphocytes suppress cell proliferation induced during development of a response in reactions of a mixed culture of lymphocytes and blast transformation irrespective of haplotypes of the cells involved in these reactions. At the same time, cytotoxic lymphocytes do not practically affect spontaneous proliferation of T-cells. The inhibitory effect of cytotoxic lymphocytes is expressed only upon direct contact with activated T-lymphocytes and is not relate to their apoptosis and death. The results obtained suggest polyfunctionality of allospecific cytotoxic lymphocytes expressed in the capacity of these lymphocytes to fulfill both effector (target lysis) and regulatory functions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Developmental Biology Springer Journals

Abstract

The data presented demonstrate the capacity of allospecific cytotoxic lymphocytes to fulfill noncytolytic regulatory functions. Cytotoxic lymphocytes suppress cell proliferation induced during development of a response in reactions of a mixed culture of lymphocytes and blast transformation irrespective of haplotypes of the cells involved in these reactions. At the same time, cytotoxic lymphocytes do not practically affect spontaneous proliferation of T-cells. The inhibitory effect of cytotoxic lymphocytes is expressed only upon direct contact with activated T-lymphocytes and is not relate to their apoptosis and death. The results obtained suggest polyfunctionality of allospecific cytotoxic lymphocytes expressed in the capacity of these lymphocytes to fulfill both effector (target lysis) and regulatory functions.
