T CELL RESPONSES TO ALLOANTIGENS II. IN VITRO INDUCTION OF SPECIFIC Ts BY HEAT-INACTIVATED ALLOGENEIC LYMPHOID CELLS

Abstract
When viable B6AF1 murine spleen cells were cultured in combination with heat-inactivated B10.D2 [murine] spleen cells under appropriate conditions, alloangitgen-specific suppressor T cells (Ts) were generated. The optimal conditions for generation for specific Ts included a responder cell number of 2 to 4 .times. 106/ml, a high stimulator to responder ratio, the use of at least 30 min of heat treatment (45.degree. C) of stimulator cells and 6 or more days of culture.
