Collagen Type Vii

We investigated the distribution of basement membrane zone (BMZ) components collagen type IV, collagen type VII, and fibronectin in human middle ear cholesteatoma, auditory meatal skin, and middle ear mucosa using both immunohistochemical and ultrastructural methods. Collagen type IV inununoreactivity of skin and middle ear mucosa is continuous in the BMZ, whereas cholesteatoma frequently showed absent immunoreactivity or focal discontinuities. Collagen type VII inununoreactivity is detected similarly within the BMZ of cholesteatoma and skin. Fibronectin immunoreactivity is observed within the dermoepithelial junction of skin and middle ear mucosa. In cholesteatoma, however, fibronectin immunoreactivity is markedly increased within the extrinsic BMZ and the subepithelial connective tissue. The ultrastructural arrangement of the BMZ of cholesteatoma is like that of skin; however, it exhibits distinct alterations of the lamina fibroreticularis and lamina densa. Our results outline cholesteatoma as a disease with disturbed cell matrix interactions analogous to those of wound reepithelialization.

The collagen component of the vessel intima consists of collagen type I, III and basement membrane collagens. For type III a particularly potent platelet aggregation activity was found earlier.Three different basement membrane collagens were isolated from call placenta. Occurence of type IV and V(A/B collagen) in the intimal and medial layer of vessel walls has been shown by chemical and immunhistological means(1). The third basement membrane collagen is probably isentical with the 55000 molecular weight component described by CHUNG et al. (2).Platelets from normal subjects were tested for aggregation and spreading on Zaponlack with type IV, V, the separated A and B chains of type V and the short chain collagen. Complete aggregation was obtained only with native type V collagen. Spreading of platelets was induced only by collagen type IV, the A chain of type V and the short chain collagen.The data indicate that all basement membrane collagens activate platelets but in different respects.1.
