Antigen-specific tolerance of T cells to minor lymphocyte stimulatory (Mls) antigens can be induced in mice by neonatal injection of foreign lymphohematopoietic cells. Although immune responses to Mlsaantigens are controlled by B cells, CD8+T cells were the most effective cell type for induction of Mlsatolerance. Tolerance was evident in both thymus and lymph nodes and could be induced by as few as 2 × 104CD8+T cells; these cells were 50 to 100 times as potent as CD4+cells or B cells in causing functional tolerance and deletion of Vβ6+T cells. Thus, intrathymic contact with antigens expressed on CD8+T cells may play an important role in controlling the normal development of tolerance.
