Compelling evidence suggests that BATF is involved in the development of multiple sclerosis (MS), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), experimental autoimmune uveitis (EAU), experimental autoimmune encephalomyelitis (EAE), and inflammatory bowel disease (IBD) [4, 10, 11]. Here, BATF is linked to rheumatoid arthritis.
