Collagen-induced platelet activation.

Author information

Department of Biochemistry, University of Cambridge, UK.


Platelet collagen receptors, such as Gp VI, are attractive targets for antithrombotic therapy. In this paper, I discuss the current knowledge regarding collagen-platelet interactions, including the role of platelet receptors, the recognition of collagen by platelets, the effect of the interaction on platelet activation and thrombosis and the effect of collagen structure on the platelet interaction, and highlight the areas in which additional information is required to pursue the goal of antithrombotic therapy, using the collagen-platelet interaction as the site of intervention. Understanding the detail of the receptor recognition motifs within collagen not only may reveal new antithrombotic targets within collagen, but will almost certainly lead to the development of defined reagents that can be used in vitro and ex vivo to explore thrombus formation further.
