AbstractThe CD8 molecule when present on a cell recognized by a mature T cell has been shown to have an inhibitory effect on the development of an in vitro immune response by that T cell. To test whether CD8 has a role in the induction of peripheral tolerance in vivo, we have studied tolerance induction in B6 female mice carrying a transgenic TCR specific to male H-Y Ag. Previous studies have shown that male Ag reactive cells are inactivated in these mice after the i.v. injection of viable male lymphoid cells. Here, B6 female transgenic mice were injected with B6 male lymph node cells from CD4 or CD8 gene knockout mice, and the fate of male Ag-specific T cells was followed in vivo. Our results indicate that injection of male CD4 knockout (express CD8) lymphoid cells but not CD8 knockout (do not express CD8) lymphoid cells induced a significant reduction of male H-Y Ag reactive cells in the periphery, suggesting that CD8 plays an important role in the induction of peripheral tolerance of class I-restricted T cells. These results imply that peripheral tolerance can be induced not just by absence of signals required for activation but by the presence of additional signals.
