Suppressor T cells arising in mice undergoing a graft-vs-host response.
We investigated the ability of mice to generate antibody-forming cells when undergoing a graft-vs-host reaction. (C57BL/6 X DBA/2)F1 mice (BDF1) injected with C57BL/6 spleen cells generated suppressor T cells which inhibit antibody synthesis by BDF1 spleen cells in vitro. These T cells arose from the donor inoculum. They differ from helper T cells in size and they act directly on antigen reactive B cells. The suppressor T cells were specifically directed against components of the H-2 region of the reciprocal parental strain (DBA/2 = H-2d) in the hybrid F1 mouse.
