How Gut Bacteria can be Linked to Rheumatoid Arthritis

The immune cell responses may cause inflammation and progressive damage to the synovial joints in patients with rheumatoid arthritis. Although genetic risk factors were identified, environmental causes may also play a role in the onset of rheumatoid arthritis. A recent study has suggested that rheumatoid arthritis can be linked to the immune responses in gut bacteria. However, how this autoimmunity of intestinal origin plays a role in RA-linked autoimmune responses was found to be unclear.
