Differential effect of restraint stress on MHC class II expression by murine peritoneal macrophages.
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.
