Inhibition of naive Th1 CD4+ T cells by glatiramer acetate in multiple sclerosis.

Abstract:

:We investigated whether glatiramer acetate (GA) treatment may affect Th1 differentiation at various T-cell maturation stages. Specifically, we analyzed the effect of in vivo GA treatment on intracellular synthesis of IL-2 and TNF-alpha by naive, memory and effector CD4(+) and CD8(+) T cells by five-colour flow cytometry. Our data indicate that GA treatment downregulates/normalizes an accelerated Th1 differentiation of CD4(+) T cells in RRMS patients at all stages of T-cell maturation. Most notably, we conclude that, by altering naive, unprimed CD4(+) T cells, GA treatment appears to affect T-cell differentiation, at least in part, in an antigen-independent manner.
