Abstract

Immunization of mice with multiple non-H-2 histocompatibility antigens results in the generation of cytolytic T lymphocytes that are specific for a limited number of immunodominant antigens. The experiments presented in this communication were designed to reveal immunodominance in pairwise combinations of autosomal and sex-linked non-H-2 histocompatibility (H) antigens. Priming and boosting responders with the male antigen, H-Y, paired with the H-4.2, H-7.1, or H-3.1 antigens, resulted in the generation of cytolytic T cells specific for the autosomal H antigens but not the H-Y antigen. Furthermore, co-immunization and boosting of C57BL/6 female responder spleen cells with BALB.B male cells resulted in the generation of cytolytic T cells specific for the BALB.B immunodominant antigens but not H-Y. No dominance was observed in H-4-plus H-7-incompatible combinations. Co-immunization of three different H-3 congenic strains with H-3.1 plus H-Y demonstrated that an efficient anti-H-3.1 T cell response is required for observing H-3.1 immunodominance over H-Y. Co-expression of H-3.1 and H-Y on the same priming and boosting cells was required for immunodominance. In fact, immunization with H-3.1 and H-Y presented on different cells resulted in normal generation of H-Y-specific cytolytic T cels, but no generation of H-3.1-specific cytolytic T cells resulted unless H-Y-specific cells were stimulated in the mixed lymphocyte cultures. These observations suggest that in vitro T cell responses to paired, non-H-2 H antigens may be independent, competitive, or synergistic, depending on the identity of the antigens and the priming and boosting conditions.
