摘要

Oncostatin M in combination with interleukin-1 (IL-1) induced a rapid and reproducible release of collagen from bovine nasal cartilage in culture. This release was accompanied by a high collagenolytic activity and low or absent tissue inhibitor of metalloproteinase-1 activity in the culture medium. Transforming growth factor-beta1 was able to block this release of collagen from the tissue, and reduce the expression and secretion of collagenases whilst maintaining TIMP-1 levels from bovine nasal chondrocytes. This study shows for the first time that TGF-beta1 can protect cartilage collagen from destruction. Copyright 2000 Academic Press.
