چکیده

Type II collagen (CII) is the major protein in articular cartilage. Autoantibodies to native and denatured CII (anti-CII) have been reported in rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA). The real meaning of the anti-CII antibodies appearance is still an open question. Anti-CII antibodies may occur more commonly very early in the disease course, suggesting that these autoantibodies could be associated with the pathophysiology of RA and JIA. This finding is supported by the fact that in collagen antibody-induced arthritis (CAIA) mouse model, immunization with anti-CII antibodies directed towards several epitopes on CII in joint cartilage can induce polyarthritis that shares several pathological features with RA. This review focuses on the inflammatory events that may be associated with anti-CII production and also the clinical application of these antibodies in RA and JIA.

Autoimmunity to citrullinated type II collagen in rheumatoid arthritis

The production of autoantibodies to citrullinated type II collagen and the citrullination of type II collagen were analyzed in rheumatoid arthritis. Autoantibodies to citrullinated type II collagen were detected in 78.5% of serum samples from 130 rheumatoid arthritis patients. Autoantibodies to native noncitrullinated type II collagen were detected in 14.6% of serum samples, all of which were p...
