Thirty-four patients with early relapsing-remitting multiple sclerosis (RRMS) were studied to clarify the differences in chemokine receptor usage by blood and cerebrospinal fluid (CSF) lymphocytes relevant to the pathogenesis of MS.

A total of 45 examinations (33 active and 12 inactive stages) revealed that circulating CD4+CXCR3+ T helper 1 (Th1) cells were increased in active MS patients and correlated with the number of gadolinium-enhanced lesions on magnetic resonance (MR) images.

In contrast, CSF samples obtained during active stages were characterized by a decrease in the percentage of CD8+CXCR3+ T cells, which was inversely correlated with CSF cell count and intra-blood-brain barrier (BBB) IgG production.
