CD4 and Behcet disease: Also, induced Overexpression of miR-155 in DCs inhibited the expression of IL-1β, IL-6 and promoted the IL-10 expression, and Overexpression of miR-155 in CD4+ T cells inhibited the expression of IL-17, which would suggest that miR-155 is a negative regulator of inflammatory cytokines in BD (109).
