Immune responses in male mice with aggressive and submissive behavior patterns: strain differences.

Immune responses in two strains of male mice with aggressive and submissive behavior patterns was studied. In aggressive CBA males immunized on the 10th day of agonistic confrontations with submissive partners, greater numbers of plaque-forming cells (PFC) and rosette-forming cells (RFC) were noted compared to control mice. Unlike the CBA strain, both PFC and RFC levels in aggressive C57BL males did not increase, but both PFC and RFC numbers decreased in submissive animals.
