内容説明

It was just about ten years ago that platelet membrane glycoproteins were first charac- terized and their abnormalities in congenital bleeding disorders first recognized. Dur- ing this decade there has been a remarkable growth in our understanding of the structure and membrane organization of the platelet surface glycoproteins, their in- teractions with external ligands during the process of hemostasis, and their defects causing hemorrhagic disease. These studies have advanced the knowledge of platelet involvement in hemostasis from a cellular to a molecular level, and they have provided a model for contact interactions among other cell types. This seemed a proper time to ask those who contributed major observations and insights during these past years to review their progress and to assess the state of our present knowledge. We have planned this volume to begin with the biochemistry of platelet membrane glycoproteins themselves and proceed through their involvement in platelet function to the final considerations of the platelet's role in maintaining the integrity of the vascular system. Our aim was an integrated presentation on the blood platelet from the perspective of its highly specialized and reactive cell surface. James N. George Alan T. Nurden David R. Phillips vii Contents I.
