Syngeneic normal lymphoid cells added in co-culture of immune lymphocytes and tumor cells reveal a suppressive activity inhibiting the generation of cytolytic T lymphocytes. The suppression was specific for the response directed against endogenous virus-induced or x-ray-induced tumor cells expressing endogenous C type virus antigens. Thymocytes, spleen cells, or lymph node cells from naive mice were able to express this suppressive activity. The same cells displayed no suppressive activity on killer cells directed against exogenous C type virus-induced tumor cells. The suppressor cells were Thy-1+, Lyt-1- 2+. Our results strongly suggested that the spontaneous suppressor cells exert their activity by interacting with an early step on the CTL response, probably at the level of the helper T cell function. The suppressive activity was mediated by soluble factor(s) that were antigen specific and possibly H-2 restricted. The possible implications of these spontaneous suppressor T lymphocytes in the development of endogenous virus-induced tumors and their possible implications in tolerance to self antigens are discussed.
