Abstract

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint inflammation, tissue damage, and fibrosis, significantly affecting the quality of life. While there are currently some effective treatments available, they often come with side effects. There is an urgent need to find new treatments that can further improve therapeutic outcomes and reduce side effects. Our study investigates the role of Mesenchymal Stem Cell exosomes (MSC-exo) combined with Ginsenoside Rh2 (Rh2) in the treatment of RA. We specifically focus on how this combined strategy influences macrophage polarization and pyroptosis. This research utilized a collagen-induced rat arthritis model. The study findings reveal that the combination of MSC-exo combined with Rh2 can inhibit the polarization of M1 macrophages, increase the proportion of M2-like macrophages, and suppress M1-like macrophage pyroptosis via the NLRP3/Caspase11/GSDMD-N pathway. In the rat arthritis model, the combination of MSC-exo and Rh2 showed synergistic therapeutic effects. This research contributes to a deeper understanding of RA’s pathogenesis and presents new potential targeted therapeutic interventions. The combined application of MSC-exo and Rh2 offers promising insights for future innovative strategies in RA treatment, paving the way for more effective management of this autoimmune disease.

期刊介绍： Established in 1999, Arthritis Research and Therapy is an international, open access, peer-reviewed journal, publishing original articles in the area of musculoskeletal research and therapy as well as, reviews, commentaries and reports. A major focus of the journal is on the immunologic processes leading to inflammation, damage and repair as they relate to autoimmune rheumatic and musculoskeletal conditions, and which inform the translation of this knowledge into advances in clinical care. Original basic, translational and clinical research is considered for publication along with results of early and late phase therapeutic trials, especially as they pertain to the underpinning science that informs clinical observations in interventional studies.
