Platelet Membrane Glycoproteins

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.

Biochemistry of Platelets is a comprehensive review of the biochemistry of platelets, with emphasis on the molecular basis for the various biological processes in which they participate. Topics range from stimulus-response coupling mechanisms to platelet contractile proteins, platelet membrane glycoproteins, and storage organelles in platelets and megakaryocytes. The expression and function of adhesive proteins on the platelet surface is also discussed. Comprised of 12 chapters, this book begins with a description of the morphological and metabolic responses to agonists, as well as the involvement of certain processes in the coupling of agonist-receptor interactions to platelet responses. The following chapter deals with platelet arachidonate metabolism and platelet-activating factor, focusing on the release of arachidonate from platelet lipid stores; pathways of platelet arachidonate metabolism and effects of arachidonate metabolites; and inhibition of platelet arachidonate metabolism by aspirin. The structure, function, and modification in disease of platelet membrane glycoproteins are then discussed, along with prothrombin activation on platelets and platelet regulation of thrombus formation. Secreted platelet proteins as markers for pathological disorders are also considered. This monograph is intended as a reference for investigators involved in platelet research as well as a source of information for those working in other areas of biological investigation.

This book provides a concise yet comprehensive summary of the current state of knowledge concerning the pathophysiology, differential diagnosis and treatment options that support day-to-day patient management. It reviews a variety of treatments including TOP-R antagonists, along with Syk inhibitor, which has recently proven to be effective, enabling readers to update and broaden their knowledge of the disease. Covering topics ranging from basic science to clinical practice, Autoimmune Thrombocytopenia will appeal to a wide readership, from medical interns and residents to clinicians and hematologists, offering them a thought-provoking, instructive and informative collection of cutting-edge works. Accordingly, readers will gain an overview of the autoimmune and other causes of the disease, and the book will serve as a foundation for new research directions that further our understanding of the pathophysiology and development of diagnosis and treatment options.p>
