摘要: Viral encephalomyelitis is caused by virus infections of neurons in the brain and spinal cord. Recovery dependent on immune-mediated control clearance from these terminally differentiated essential cells. Preservation neuronal function for prevention neurologic sequelae such as paralysis, seizures cognitive deficits. Using model system Sindbis virus-induced mice, we have shown that infectious a noncytolytic process. The major effectors are antibody to E2 surface glycoprotein produced B cells, interferon-γ T These work synergy, but populations differ their responses each. Virus least likely be cleared most motor cervical thoracic regions Because infected not eliminated, viral RNA persists long-term needed prevent reactivation. Virus-specific antibody-secreting cells residing nervous after recovery infection important control.
