[Effect on the immobilization-induced stress on the immune response in mice with various behavioral stereotypes].

CBA and C57BL/6J mice with aggressive and submissive types of zoo-social behavior fixed during 10-day confrontation testing demonstrated different immune response to immobilization stress. In aggressive mice with confrontation experience stress resulted in a decrease in the immune response in comparison with aggressive inexperienced mice. Therewith, the immune response of CBA mice did not differ from the control level (the immunized mice without experience of victories and defeats), and in C57BL/6 mice the immune response was two times lower than in the control. In contrast to the control and aggressive mice, stress did not suppress the immune response in submissive animals. It is suggested that stress-induced changes in the immune response depend on zoo-social rank of an individual underlain by a particular neurochemical pattern of the brain.
