摘要

To determine whether matrix metalloproteinase-1 (MMP-1) or MMP-3 is involved in cartilage collagen degradation, polyclonal antibodies were separately raised against MMP-1 and MMP-3 and their effects on collagen degradation were assessed in rabbit cartilage explant culture. We found that anti-MMP-1 antibodies completely inhibited collagen degradation induced by the combination of interleukin-1 (IL-1) and plasminogen. Anti-MMP3 antibodies showed 40% inhibition at maximum concentration. These results indicate that MMP-1, and possibly MMP-3, are involved in collagen degradation in cartilage explant culture.
