Eicosapentaenoic acid (EPA), one of the n-3 polyunsaturated fatty acids, is a neuroprotective lipid with anti-inflammatory properties. We investigated the possible therapeutic effect of EPA on experimental autoimmune encephalomyelitis (EAE). EAE mice were fed a diet with or without EPA. The clinical EAE scores of the EPA-fed mice were significantly lower than those of the non-EPA mice. In the EPA-treated mice, IFN-γ and IL-17 productions were remarkably inhibited and the expression levels of peroxisome proliferator-activated receptors were significantly enhanced in the CNS-infiltrating CD4T cells. Thus EPA shows promise as a potential new therapeutic agent against multiple sclerosis. Copyright © 2012 Elsevier B.V. All rights reserved.
