cumulating evidence points to a key role for cd8+ t cells in the pathogenesis of multiple sclerosis.cd8 expression level was believed to be present constantly on the surface of human peripheral blood t cells. however, it was shown that peripheral blood lymphocytes may be divided by the level of cd8 expression, into cd8+high and cd8+low t cells. now it is well established that the cd8low populat...
