Myeloid-derived suppressor cells (MDSCs) are a group of cells that regulate the immune response and exert immunosuppressive effects on various immune cells. Current studies indicate that MDSCs have both anti-inflammatory effects and proinflammatory effects on rheumatoid arthritis (RA) and RA animal models. MDSCs inhibit CD4(+)T cells, which secrete proinflammatory factors such as IFN-gamma, IL-2, IL-6, IL-17, and TNF-alpha, by inhibiting iNOS, ROS, and IFN-gamma and promoting the production of the anti-inflammatory factor IL-10. MDSCs can suppress dendritic cells by reducing MHC-II and CD86 expression, expand Treg cellsin vitrothrough the action of IL-10, inhibit B cells through NO and PGE(2), and promote Th17 cell responses by secreting IL-1 beta. As a type of osteoclast precursor cell, MDSCs can differentiate into osteoclasts through activation of the NF-kappa B pathway via IL-1 alpha. Overall, our study reviews the research progress related to MDSCs in RA, focusing on the effects of MDSCs on various types of cells and aiming to provide ideas to help reveal the important role of MDSCs in RA.
