Abstract Recently, we investigated the effects of eicosapentaenoic acid (EPA), a fatty acid which modulates immune response and stimulates myelin gene expression, in an established model of multiple sclerosis (MS): the experimental autoimmune encephalomyelitis (EAE) induced in Dark Agouti rats. As scientific evidences and our previous studies have suggested that EPA could directly affect oligodendrocytes, we have now evaluated the effects of EPA in the non-immune mediate MS model characterized by selective oligodendrocytes damage induced by cuprizone (CPZ). We found that feeding weanling rats diets containing 0.6\% CPZ for 2 weeks induced variation of whole brain and myelin biochemical composition representative of a severe myelin damage. We thus administered daily and by gavage EPA or PBS to 2-day old rats up to 21 days. Afterwards, rats were fed CPZ diet for 9 days. The results show that compared to PBS/CPZ fed rats, the whole brain cerebroside content in EPA pre-treated rats was statistically increased as well as there was an overall trend of increase of all other biochemical components. © 2013 Published by Elsevier Ltd.
