摘要：

Tumour necrosis factor-alpha (TNF-alpha) was able to promote collagen breakdown from bovine cartilage in explant culture. This release was dependent upon matrix metalloproteinases (MMPs) and could be prevented by transforming growth factor-beta1 (TGF-beta1) or insulin-like growth factor-1. Both growth factors reduced the expression and secretion of collagenase enzymes, and TGF-beta1 induced tissue inhibitor of metalloproteinase production. This study shows for the first time that these anabolic growth factors can protect cartilage against TNF-alpha -induced destruction. (C) 2001 Academic Press.
