Input: The neurotropic murine coronavirus, MHV-JHM (JHMV) causes encephalitis and paralytic-demyelinating disease in susceptible strains of mice and rats, serving as a model for human demyelinating diseases such as multiple sclerosis. In this communication, we report that a single intracerebral administration of the naturally occurring neuropeptide, fl-endorphin, reduced the incidence of JHMV-induced paralytic-demyelinating disease 40-50% in C57B1/6 mice. Protection from disease was accompanied by significantly reduced virus replication in the brain as early as 3 days post-infection and did not occur in irradiated, or immunoincompetent mice. The data suggest that fl-endorphin engages immune mechanisms of host resistance to JHMV infection to protect the mice from disease.
