Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by systemic immunity and autoimmune disorders. We have previously found that oxymatrine (OMT), a natural alkaloid, can alleviate rheumatoid arthritis without knowing whether OMT can alleviate rheumatoid arthritis through gut microbiota. In this study, we found that OMT can alleviate collagen-induced arthritis in mice and reconstruct the immune balance of Th1/Th2, Treg/Th17, and Tfr/Tfh cells. Colon transcriptome gene enrichment analysis indicated that oxymatrine may alleviate collagen induced arthritis in mice through immune system process pathway. Furthermore, OMT significantly altered the gut microbiota variety, changed the composition of microbial colonies, and reshaped the gut microbiota of collagen-induced arthritis (CIA) mice, which may participate in the regulation of the balance of Th1/Th2, Treg/Th17, and Tfr/Tfh cells to alleviate collagen-induced arthritis in mice.
