Mechanisms of virus-induced demyelination and remyelination.

Viral models of demyelination and remyelination provide important clues to the pathogenesis of multiple sclerosis. Determining the precise viral polypeptides recognized by T cells during the demyelinating process will be important in understanding the mechanisms of viral-induced myelin destruction. Isolation, purification, and characterization of factors that promote remyelination and proliferation of oligodendrocytes may provide hope in the treatment of patients with chronic demyelinating disorders.
