Cytokines in the pathogenesis of multiple sclerosis.

ABSTRACT

The authors evaluate the involvement of various cytokines (interleukin-1, interleukin-2, interleukin-4, interleukin-6, tumor necrosis factor alpha and gamma-interferon) in the pathogenesis of multiple sclerosis. The cytokines might participate in nervous tissue damage by promoting demyelination and oligodendrocyte injury or by enhancing local immune response. In addition, several authors reported increased levels of some cytokines in serum and cerebrospinal fluid of patients with multiple sclerosis. These findings suggest that cytokines can play a significant role in the immunopathogenesis of the disease.
