[Pathological and protective effects of tumor necrosis factor-alpha in multiple sclerosis]. / Patologicheskie i protektivnye éffekty faktora nekroza opukholi-al'fa pri rasseiannom skleroze.

ABSTRACT

The immunomodulatory cytokine tumor necrosis factor-alpha (TNF-α) is involved in the regulation of both physiological and pathological processes in the central nervous system (CNS). The effects of TNF-α on CNS reported in clinical trials and experimental studies, evidence of involvement of this cytokine in the pathogenesis of multiple sclerosis are analyzed. Possible causes of failures of non-selective pharmacological inhibition of TNF-α effects in MS are considered in view of current concepts on mechanisms of TNF-α action.
