Stress-related modulation of central nervous system immunity in a murine model of herpes simplex encephalitis.
This study assesses the immunomodulatory effects of stress on the pathogenesis of herpes simplex encephalitis (HSE) in a mouse model. Physical restraint served as the stressor and HSE developed subsequent to HSV-1 inoculation into the tongues of subject animals. Clinical data showed that stressed mice lost more weight and had greater mortality rates than unrestrained animals during the course of infection. Histologic tissue sections demonstrated a stress-related reduction of the cellular inflammatory response in the central nervous system (CNS). This model may be useful to further investigate the mechanisms of stress-related immunosuppression in the CNS.
