title: Experimental erythrocyte autoimmunity. IV. Differential susceptibility to irradiation of suppressor cells for anti-rat RBC antibodies and suppressor cells for mouse RBC autoantibodies.
abstract: Mice injected with rat erythrocytes (RBC) produce RBC autoantibodies and antibodies against rat RBC. Transfer of spleen cells from autoantibody-producing mice to syngeneic recipients before the series of rat RBC injections causes a significant delay in autoantibody production although the response against rat RBC is elevated. Here it is shown that antibodies against rat RBC are markedly increased in recipients exposed to 350 rad of whole-body irradiation before transfer of spleen cells and the injections of rat RBC. In contrast, autoantibody production remained significantly suppressed. This shows that the anti-rat RBC response is regulated, at least in part, by cells in normal mice that are abrogated by 350 rad of whole-body irradiation.
