Research underscores the importance of autoantibodies as disease drivers in rheumatoid arthritis

RA is a destructive autoimmune disease in which the body’s immune system attacks its own joints. Ongoing research aims to determine the vital role of pathogenic autoantibodies specific to RA, such as rheumatoid factors (RF) and anti-citrullinated protein antibodies (ACPA). These biomarkers can be important diagnostic and prognostic factors for guiding treatment decisions during the course of the disease. A new initiative — Rheumatoid Arthritis, Redefined — offers information and resources for physicians. Learn more.
