Departments of Pathology & Pharmacology Loyola University Medical Center 2 1260 South First Ave. Maywood, IL 60153,USA PREFACE Despite my many years of research and teaching in platelet physiology and pharmacology at the University of Minnesota, I am often confronted with conflicting opinions as to the relevance of nonnucleated platelets in human health and disease. It is fascinating to think that how cells with no apparent nucleus, have such a towering impact on concepts, dealing with often overlapping physiological (i.e. hemostasis, wound healing, etc.) and pathophysiological (i.e. thrombosis, stroke, atherosclerosis, wound healing, diabetes, inflammation and cancer) components. Although the idea of compiling new frontiers of platelet research in the form of a book was quite simple at the beginning, the project turned out to be a major undertaking from my part. At the end, I am elated that the contributors to this book were gracious enough to write chapters in their area of research expertise despite their pressing and highly valuable time. For me, it has been an humbling experience as the chapters that I have compiled, are written by people with incredible recognition for their relentless contributions over the years to strengthen the understanding of platelet physiology and pharmacology. In my opinion, this has added an immense value to the book. I am proud to have been involved in this undertaking despite several unexpected problems and delays during this project. I am confident that this book would be highly useful to the community of scientists, including graduate students, researchers, academicians, physicians and other health care professionals, and pharmaceutical industry scientists. Circulating platelets which lack nucleus neither adhere to the vessel wall nor aggregate unless they encounter a zone of injury. Upon encountering such a zone of injury, they become almost instantly activated, which leads to their adhesion and aggregation, both reactions are of fundamental importance to hemostasis and thrombosis. Because of this reason, platelet research has clearly led the way in the continuing development of new strategies and drugs that can help prevent and treat arterial thrombosis, stroke and atherosclerosis. Unquestionably, platelet research has also impacted concepts dealing with many other diseases. Nevertheless, considerable progress has been made in the development of new antiplatelet agents in recent years. These newer agents are aimed at interrupting specific sites and pathways of platelet activation. Inhibitors of specific platelet agonist-receptor interactions include antithrombins, thromboxane A 2 receptor antagonists, and adenosine diphosphate receptor blockers (i.e. ticlopidine, clopidogrel). In addition, inhibitors of arachidonic acid metabolism and thromboxane A 2 include aspirin, newer COX-2 inhibitors, other NSAIDs, thromboxane A 2 synthase inhibitors and o>-3 fatty acids. Moreover, long awaiting drugs that block ligand binding to the platelet glycoprotein Ilb/IIIa complex (i.e. tirofiban) have now entered the market. In this book, the chapters are organized into six major sections, including Introduction, Receptor Biology, Platelet Biochemistry, Experimental Physiology, Platelet Pathology and Platelet Pharmacology. Authoritative chapters in each section have provided a collective strength to our initial philosophy of accomplishing a comprehensive review of current concepts in each discipline. Although every attempt has been made to provide an interdisciplinary discussion on the subject of platelets in this book, there may still be some gaps and lapses for which readers are urged to consult other articles and reviews. I have deliberately avoided going into any specific comments on reviews in order to let the imagination of the readers flow freely. I believe that the readers are intelligent enough to judge and form their own critical opinion. I must humbly express my deep gratitude to thirty five scientists in the field for their invaluable contributions. I now honestly believe that this publication would not have been possible without their meritorious contributions. I am deeply indebted to my dear friend and close research collaborator, Mahadev Murthy, Ph. D., Director of Research, Division of Endocrinology, Metabolism and Nutrition, Department of Medicine, Hennepin County Medical Center, Minneapolis, MN, USA, for his commitment and contribution to this project. He has spent countless hours during this project in reviewing and preparing camera ready manuscripts for final submission to the Kluwer Academic Publisher. In addition, he has written two excellent chapters for the book. I must confess that this publication would not have been completed without his generous and truly dedicated efforts. I would like to take this opportunity to thank Charles W. Schmieg, Jr., Acquisitions Editor, Kluwer Academic Publishers, 101 Philip Drive, Assinippi Park, Norwell, MA, 02061, USA, for facilitating the publication of this book. I am specially thankful for his cooperation and patience even though this project was delayed by about four months. Finally, I would not be in this field today without my mentor, James G. White, M. D., Regents' Professor & Associate Dean, Academic Health Center, University of Minnesota, Minneapolis, MN, USA. I humbly dedicate this publication to James G. White, M. D., who has been my mentor, teacher, associate and dear friend, during my long career in platelet research. In the end, my academic success and accomplishments over the years, would not have been possible without the support of my wife Yashoda, my daughter Aupama and my son Prashanth. I sincerely acknowledge and appreciate their patience and support throughout my career. Gundu H. R.
