"Herbal compound and biodegradable polymer system show promise in treating rheumatoid arthritis"
Researchers from Osaka University have identified a protein complex, COMMD3/8, that promotes the progression of rheumatoid arthritis and found that celastrol, an extract from the root of a medicinal plant, is a potent inhibitor of the COMMD3/8 complex. Celastrol impairs the antibody response and blocks the progression of rheumatoid arthritis in a mouse model. The COMMD3/8 complex is central to the pathogenesis of rheumatoid arthritis and autoimmune conditions, making it a promising therapeutic target for autoimmune diseases.
