Abstract:
:The results presented in this report demonstrate that T cells, isolated from AGUS rats bearing long-term (WAG X AGUS)F1 spleen allografts adoptively transferred to irradiated AGUS recipients could not mediate the rejection of WAG hearts but rejected PVG. A hearts in acute fashion. Further, unresponsive T cells were able to suppress the capacity of adoptively transferred (40 X 10(6) normal T cells to reject WAG but not PVG.A heart allografts. We also studied the role of W3/25+ and OX8+ T cells subsets in the maintenance of unresponsiveness. Isolated W3/25+ or OX8+ unresponsive T cells were not able to mediate acute rejection, but were less effective in prolonging WAG allograft survival than the unresponsive whole T cell population, suggesting that both W3/25+ Ts1 and OX8+ Ts2 subsets were required for effective suppression in vivo. When, however, unresponsive W3/25+ T cells were infused simultaneously with normal OX8+ T cells, they could produce indefinite survival of WAG heart allografts. These results indicate that the unresponsive state induced by (WAG X AGUS)F1 spleen allografts transplanted to AGUS rats is maintained by the interaction of W3/25+ T suppressor/inducer and OX8+ T suppressor/effector cells.
