Inhibition of collagen-induced platelet aggregation by antibodies to distinct types of collagens
Abstract
Aggregation of platelets by fibrils formed from collagens type I, II and III could be inhibited by coating the fibrils with anti-collagen antibodies or Fab fragments. Similar results were obtained in a clot-retraction assay. Inhibition was achieved with stoichiometric amounts of antibodies and was specific for each type of collagen. Aggregation caused by a mixture of type-I and -III collagens could only be inhibited by a mixture of antibodies against both collagens. The data show that each interstitial collagen is capable of interacting with platelets and do not support the concept of an outstanding activity of type-III collagen.
