Abstract

The effect of restraint stress on the expression of MHC class II glycoproteins by peritoneal macrophages was evaluated. Restraint suppressed the expression of I-A by macrophages from mice that are susceptible to Mycobacterial infection. In contrast, restraint did not affect I-A expression by macrophages from resistant mice. The suppression of MHC class II expression required at least 8 h of restraint and recovered within 4 h after stress. The amount of restraint necessary to suppress I-A expression also resulted in higher levels of plasma corticosterone. Changes in I-A expression were under circadian rhythm control. The differences in the effect of restraint stress on expression of I-A by peritoneal macrophages from resistant and susceptible mice may, in part, be due to differences in the effect of corticosterone in MHC class II expression.
