摘要：

We compared the chemical and immunological properties of cuticular collagens from four species of filarial nematodes, Onchocerca volvulus, O. gutturosa, Brugia malayi, and Dirofilaria immitis. The electrophoretic mobility of the major polypeptides extracted from adult worms is characteristic for each species studied. Cuticular collagens from adult worms and infective larvae differ in their susceptibility to proteases that cleave vertebrate collagens and to collagenases prepared from different developmental stages of filarial parasites. The overall amino acid composition of filarial collagens resembles that of vertebrate interstitial collagens and differs from that reported for collagens from free-living or intestinal nematodes. However, cuticular proteins of the four filarial species studied significantly differed in amino acid composition and in their reactivity with antisera to interstitial and basement membrane collagens of vertebrates. © 1991.
