H-2 antigen requirements in the in vitro induction of SV40-specific cytotoxic T lymphocytes.
T cytotoxic cells generated to syngeneic SV40 virus transformants lyse only SV40 target cells that are syngeneic at the H-2 locus. In contrast, SV40-specific tumor transplantation immunity shows no requirements for syngeneic H-2. Inoculation of allogeneic or even xenogeneic transformants will confer immunity to a challenge of syngeneic SV40 tumor cells. The experiments described here represent an attempt to reconcile these apparently conflicting observations. In our hands, generation of SV40-specific T cytotoxic cells in vitro requires both in vivo priming and secondary in vitro sensitization. We have found that priming for a secondary syngeneic-restricted response requires only that the cell employed be SV40 transformed. That is, priming may be accomplished with syngeneic, allogeneic, or xenogeneic SV40 transformants. Thus, the apparent lack of H-2 restriction in vivo immunity does not eliminate a role for the H-2-restricted cytotoxic T cell in tumor transplantation immunity.
