Tumor immunity to murine plasma cell tumors. V. Genetic control of the in vitro cytotoxic T-cell response to plasma cell tumor-associated antigens of NZB mice.
Cytotoxic T-lymphocytes (Tc) were induced in vitro to plasmacytoma tumor-associated antigens (TAA) by coculture of irradiated cells of plasma cell tumors (PCT) from NZB mice and viable nonimmune or PCT-immune spleen cells from NZB. (NZB X C57BL)F1, (NZB X B10.D2)F1, and (NZB X B10,BR)F1 mice. When nonimmune spleen cells were used, major histocompatibility complex (MHC)-linked genetic control of te primary in vitro induction of Tc to NZB PCT was demostrated for a shared TAA expressed on NZB and BALB/c PCT. Evidence was also obtained for a non-MHC-linked genetic control of the primary in vitro induction of Tc to a second TAA that ws expressed on both PCT and T-lymphomas. When the spleen cells were obtained from mice preimmunized to an NZB PCT, a secondary in vitro Tc response was observed, and a PCT-specific and strain-specific TAA or NZB mice was identified. In addition, results with the F1 hybrids also indicated an MHC-linked genetic control of the in vitro Tc response to this strain-specific TAA.
