The Platelet Amine Storage Granule presents a comprehensive examination of the dense granule of human platelets and the development of dense granule precursors in megakaryocytes. Fundamental aspects addressed in the book include a description of the amine-nucleotide storage complex, the process of granule secretion (with focus on inositol phosphate metabolism), modulation of secretion by epinephrine, and a description of platelet storage pool disease. The book's broad coverage of the topic makes it a valuable resource to hematologists, cell biologists, platelet biologists, medical and veterinary geneticists, neurobiologists, endocrinologists, physiologists, and pharmacologists.
