Preface
Blood Cell Biochemistry was initially conceived as part of the Plenum series Subcellular Biochemistry, from which it has developed into a separate series. The present volume is devoted primarily to contributions on megakaryocytes and platelets and, to a lesser extent, to macrophages and eosinophils. The book does not attempt a rigorous or total coverage of the particular topics; it represents the areas of current scientific activity and interest that were selected by the editor at the commencement of this project. In general, the approach has been similar to that adopted for Volume 1 of the series (Erythroid Cells); the same approach will be followed subsequently in Volume 3 (Lymphocytes and Granulocytes).
This book opens with a developmentally oriented chapter by Janine Breton-Gorius on megakaryocyte maturation and platelet release in normal conditions, which serves to set the scene ultrastructurally for much of the data that follow. The biosynthesis and processing of platelet glycoproteins in megakaryocytes is dealt with by Alain Duperray and his colleagues, and thereby provides an in-depth biochemical survey of the megakaryocyte. The applications and strengths of crossed immunoelectrophoresis for the study of platelet membrane proteins is then covered by Simon Karpatkin, and a detailed account of the heredity disorders of platelet function is provided by Francine Rendu and Evelyne Dupuy. An impressive ultrastructural presentation, by James G. White, on the cytoskeleton of human blood platelets is appropriately complemented by the chapter by J. Michael Wilkinson, which describes immunological studies on the platelet cytoskeleton. The two following chapters, on macrophages, deal with the effect of lipoproteins and platelets on macrophage cholesterol metabolism (by Michael Aviram) and on macrophage membrane and macrophage structure and function (by Yasuko Shibata and his colleagues). The final chapter (by Ann M. Dvorak and her colleagues) is a detailed ultrastructural presentation on the morphology and function of human eosinophils.
The combination of biochemical and ultrastructural data included within this book, as in the first volume of the series, indicates the strength of this methodological combination as a means for providing an overall view to assist our understanding of blood cell structure and function. Although it must be acknowledged that some relevant topics are not included (due either to their absence in the initial list or to authors backing out during production), it is expected that future volumes of the series will rectify such omissions.

is hoped that this volume will be of use to hematologists, biochemists, and cell biologists whose areas of research fall within the sphere of the topics covered and, in a broader context, to all those interested in blood cells.
