概要	We evaluated 30 patients with clinically definite multiple sclerosis (MS) and 8 patients with neuromyelitis optica (NMO) to investigate correlations between Th1/Th2 balance, disease activity, effects of interferon (IFN)-β treatment, and expressions of chemokine receptors CXCR3 and CCR4 on CD4+ and CD8+ T cells in peripheral blood. MS and NMO patients in the relapsing phase showed a significantly increased CD4+CXCR3+/CD4+CCR4+ ratio and CD8+CXCR3+/CD8+CCR4+ ratio compared with respective patients in the remission phase. After IFN-β treatment, the CD4+CXCR3+/CD4+CCR4+ ratio and CD8+CXCR3+/CD8+CCR4+ ratio were significantly decreased compared with the relapsing phase and slightly lower than in the remission phase. The CD8+CXCR3+/CD8+CCR4+ ratio showed a more marked change associated with disease activity than CD4+ T cells in MS and NMO patients. Moreover, in patients in the relapsing phase of NMO, the CD4+CXCR3+/CD4+CCR4+ ratio and CD8+CXCR3+/CD8+CCR4+ ratio were significantly higher than in MS patients in the relapsing phase. We confirmed marked changes in the CD8+CXCR3+/CD8+CCR4+ ratio according to disease activity and treatment of MS and NMO. Furthermore, this ratio was more strongly linked to immune and inflammatory activity in NMO patients than in MS patients, and may represent an important factor in differentiating the pathogenesis of MS and NMO.
