Abstract

Cytotoxic effector T cells specific for non-H-2 histocompatibility (H) antigens were examined for phenotypic expression of lymphocyte differentiation (Ly) antigens. Virtually all H-Y-specific cytotoxic effectors generated in mixed lymphocyte culture were Ly-1+2+ T cells. H-3-specific effectors comprised both Ly-1+2+ and Ly-1-2+ T cells. However, cytotoxic effectors specific for multiple non-H-2 H antigen-specific effectors required an interaction between Ly-1+2- and Ly-1-2+ T cells. These observations suggest that the identity of the target H antigen in part determines the Ly type of responsive T cells. Our observations suggest that 2 alternative pathways of T cell response exist for non-H-2 H antigens. The first pathway involves an interaction between Ly-1+2- helper T cells and Ly-1-2+ cytotoxic effector precursors. The 2nd pathway simply involves the response of Ly-1+2+ T cells proliferating and generating H antigen-specific cytotoxic effectors.
