Brief description/objective

Multiple sclerosis (MS) is an autoimmune disorder directed against self antigens of the central nervous system. CD4(+)CD25(+)FoxP3(+) regulatory T cell (T(reg)) mediated suppression is an essential mechanism of self-tolerance. We studied whether changes in the suppressive function of a mixture of CD25(high) and CD25(intemediate) expressing T(reg) cells in myelin basic protein (MBP)-induced proliferation occurred in untreated MS patients. Suppression of MBP-induced proliferation was observed in 13 out of 29 (45%) MS patients; this was significantly (p<0.05) less compared with 17 out of 19 (89%) healthy individuals. Relative T(reg) counts was significantly increased in MS patients (mean+/-S.D.; 20+/-8%) compared with healthy individuals (15+/-5%). These findings suggest that impaired T(reg) function may be involved in pathogenesis of MS.
