ObjectiveTo review the role of dendritic cells (DC) in immune metabolism of rheumatoid arthritis (RA). MethodsLiterature on the role of DC in the immune metabolism of RA was extensively reviewed in recent years, and the metabolic characteristics of RA, the role of DC in RA, the correlation between the immune metabolism of DC and RA, and the treatment were summarized and analyzed. Results DC promotes the progression of RA under hypoxia, increased glycolysis, inhibition of oxidative phosphorylation, and decreased lipid metabolism. Moreover, many DCs (especially conventional DC and monocyte-derived DC) have different functions and phenotypic characteristics in RA, which are closely related to the occurrence and development of RA. Conclusion DC plays an important role in the immune metabolism of RA, and immunometabolism therapy based on DC can provide targeted therapy for the treatment of RA.
