Recent investigations support that an anti-aging protein, namely Klotho, protects neurons against the oxidative stress and demyelination. We evaluated the protein concentration of Klotho and total anti-oxidant capacity (TAC) in the cerebrospinal fluid (CSF) of patients with relapsing-remitting multiple sclerosis (RRMS). Klotho concentration and TAC were significantly lower in patients as compared to controls. Klotho values showed a significant negative correlation with expanded disability status scale (EDSS). Moreover, a significantly positive correlation between TAC levels and Klotho concentrations was detected. Klotho may play an important role in the pathogenesis of MS, at least in part, through the regulation of redox system.
