Abstract
Endotoxin shock is a life-threatening response caused by a disordered immune response to an infection. MDSCs are accumulated and play a protective role in the pathogenesis of endotoxin shock. However, the regulation of MDSCs by small molecule remains unrevealed. Here, we report that arctigenin, a small molecule extracted from Arctium lappa, induces accumulation of functional MDSCs. Arctigenin was able to ameliorate LPS-induced inflammation through accumulating MDSCs, especially granulocytic MDSCs (G-MDSCs), and enhancing the immunosuppressive function of MDSCs in vivo and in vitro. Mechanistically, arctigenin promoted the accumulation of MDSCs through upregulating miR-127-5p which targets the 3′UTR of interferon regulatory factor-8 (IRF8) mRNA. In addition, arctigenin enhanced the immunosuppressive activity of MDSCs on M1 macrophage polarization by elevating the expression of arginase 1 (Arg-1) and inducible nitric oxide synthase (iNOS). Our study provides new insights into the regulation of functional MDSCs by arctigenin in exerting immune responses and pathogenesis of inflammatory diseases.
