Rheumatoid arthritis is a chronic (long-lasting) inflammatory disease that causes pain, stiffness, warmth, redness and swelling in joints. Over time, the affected joints may become misshapen, misaligned and damaged.
Researchers are working to understand what causes rheumatoid arthritis. Rheumatoid arthritis (RA) is a complex disease in which the patientâs immune system attacks its own tissue causing swelling and inflammation in the joints and damage of tissues and other organs.uch of the rheumatoid arthritis research being conducted focuses on immune mechanisms involved. Many of these mechanisms are shared with other autoimmune diseases that attack different organs, such as lupus (kidneys), multiple sclerosis (brain) and Type I diabetes (pancreas).
