چکیده انگلیسی
Dendritic cells (DC) constitute a complex system of uniquely specialized antigen-presenting cells (APC) that play crucial roles in the initiation and regulation of immune responses. Recent studies have demonstrated that DC silenced by siRNA IL-12 p35 showed tolerogenic capacity in vitro. However, their mechanism of action is not fully understood. In this study, IL-12p35 siRNA was chemically synthesized and transfected into DCs. A coculture of T cells and DCs was performed. After 30Â min coculture, T cells were harvested and analyzed. We showed that the IL-12 p35 silenced DCs decreased IL-12-induced T cell responses through blocking tyrosine phosphorylation of JAK2, TYK2, STAT3, and STAT4 proteins in T cells. These results demonstrate IL-12 p35 silenced DCs modulate immune responses by blocking IL-12 signaling through JAK-STAT pathway in T cells.
