[Biochemistry of collagen and locomotor apparatus. Hereditary diseases of the connective tissue and rheumatic diseases (3)].
In inflammatory granuloma, synovial sclerosis or inflammation and in Dupuytren's contracture, the neocollagen contains chains and/or transverse links that are characteristic of rapidly growing immature tissues. In arthrosis, a conversion of collagen synthesis towards a cutaneous type may occur. The destruction of cartilage in rheumatoid arthritis is brought about by a specific collagenase that originates from the inflamed synovial membrane. Finally, certain forms of osteoporosis may be due to alterations of the osseous collagen which impair the mechanism of calcification.
