The effect of intravenously injected tumor immune spleen cells on growth of 3 x 105 gliosarcoma T9 cells injected intradermally (ID) or intracerebrally (IC) into sublethally irradiated CDF rats was evaluated. Spleen cells from donor rats with sufficient immunity to reject 5 x 105 T, cells inhibited the growth of T, cells mixed with spleen cells in a ratio of 1:25 and injected ID, but could not act after intravenous transfer. However, donor rats which had rejected increasing T9 challenge doses up to 1 x 107 cells produced immune spleen cells which, upon IV transfer, could inhibit growth of ID T9 challenge but not of EB-679, an unrelated glioma, in recipient rats. Rejection of IC T9 challenge was also obtained after IV transfer, in recipients of such “hyperimmune” spleen cells, but was less (60% maximum) than that noted after ID T9 challenge (100% maximum). The removal of B cells from the transferred spleen cells did not affect the results, suggesting that the specific immunity was mediated by T cells. We conclude that the special immunological circumstances of tumors growing in the brain renders them less accessible to rejection by systemically transferred immune cells, but it is nevertheless possible to effect a significant incidence of rejection of syngeneic tumor growth in the brain by the intravenous transfer of hyperimmune spleen cells.
