Collagenase at Sites of Cartilage Erosion in the Rheumatoid Joint

Arthritis Rheum. Jul-Aug 1977;20(6):1231-9. doi: 10.1002/art.1780200612.

Abstract

Immunolocalization studies of rheumatoid tissues employing specific synovial collagenase antibody have demonstrated immunoreactive enzyme at the cartilage/pannus junction. Collagenase was not detected in chondrocytes or the cartilage matrix remote from the resorbing front, and relatively little enzyme was observed in the hypertrophied synovial membrane itself. These observations directly support the idea that synovial collagenase participates in cartilage erosion in rheumatoid arthritis.
