The Endothelium by Michel Félétou Pdf

The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

Vascular Endothelium by John D. Catravas,Allan D. Callow,C. Norman Gillis,Una S. Ryan Pdf

This monograph contains the proceedings from the Advanced Study Institute on "Vascular Endothelium: Physiological Basis of Clinical Problems" which took place in Corfu, Greece in June 1990. The meeting consisted of twenty-eight lectures, most of them adapted as full length papers in this volume, as well as numerous short oral and poster communications which are abstracted and also included in alphabetical order (pages 239-302). There were ninety-six participants from ten NATO and four other European countries. The meeting was the second in as many years dealing with a specific subject in Endothelial Cell biology. Following the 1988 discussion on "Receptors and Transduction Mechanisms", the present ASI recognized and tried to deal with the increasing overlap in interest between basic scientists studying endothelial cell functions and clinicians facing problems of known or suspected endothelial pathological involvement. As with any similar effort, we opted to be selective, rather than fail by trying to be inclusive, in the subjects covered. We chose to discuss diseases, such as atherosclerosis, sepsis, ARDS and stroke, based on their relevance to endothelial cell function and urgent need for new insights into their pathogenesis and treatment. Similarly, we examined endothelial cell functions by considering their relevance to disease and their potential for elucidating important pathologies. Obviously, some areas were covered superficially or not at all; this should not distract from their importance, but rather reflect on the constraints of time and -not at all negligibly -the bias of the organizing committee.

Regulation of Endothelial Barrier Function by Sarah Y. Yuan,Robert R. Rigor Pdf

The vascular endothelium lining the inner surface of blood vessels serves as the first interface for circulating blood components to interact with cells of the vascular wall and surrounding extravascular tissues. In addition to regulating blood delivery and perfusion, a major function of vascular endothelia, especially those in exchange microvessels (capillaries and postcapillary venules), is to provide a semipermeable barrier that controls blood–tissue exchange of fluids, nutrients, and metabolic wastes while preventing pathogens or harmful materials in the circulation from entering into tissues. During host defense against infection or tissue injury, endothelial barrier dysfunction occurs as a consequence as well as cause of inflammatory responses. Plasma leakage disturbs fluid homeostasis and impairs tissue oxygenation, a pathophysiological process contributing to multiple organ dysfunction associated with trauma, infection, metabolic disorder, and other forms of disease. In this book, we provide an updated overview of microvascular endothelial barrier structure and function in health and disease. The discussion is initiated with the basic physiological principles of fluid and solute transport across microvascular endothelium, followed by detailed information on endothelial cell–cell and cell–matrix interactions and the experimental techniques that are employed to measure endothelial permeability. Further discussion focuses on the signaling and molecular mechanisms of endothelial barrier responses to various stimulations or drugs, as well as their relevance to several common clinical conditions. Taken together, this book provides a comprehensive analysis of microvascular endothelial cell and molecular pathophysiology. Such information will assist scientists and clinicians in advanced basic and clinical research for improved health care.

Vascular Endothelium by John D. Catravas,Allan D. Callow,Una S. Ryan Pdf

This book is a compilation of the lectures and oral and poster communications presented at the Advanced Study. Institute on "Vascular Endothelium: Physiological Basis of Clinical Problems II," which took place between June 20 and 30, 1992 in Rhodes, Greece. This third in a series of ASIs on vascular endothelium continued on the theme of the first (1988) ASI on "Receptors and Transduction Mechanisms" and particularly expanded that of the 1990 conference on ''Physiological Basis of Clinical Problems. " We continued the successful practice of bringing together clinicians and scientists: this was reflected equally well in the composition of the organizing committee as in the background of the particiJ?ants. Endothelial cell functions and dysfunctions present as many challenges to the mvestigator as they do to the curious clinical practitioner. As these problems are necessarily different, this unique ten-day co-habitation of these individuals continued to offer fresh outlooks to each, stimulated potential collaborative efforts and, most importantly, advanced --ever so slightly--our knowledge of vascular biology. This year's conference was further enriched by the presence of several of our colleagues from Eastern Europe whom we are delighted to welcome as officially sponsored participants to this and future NATO-supported meetings. It is never superfluous to remind readers and participants that those signing at the bottom of this page, while responsible for many of the ASI's and the book's deficiencies, are but three of the many contributors to the successes.

Biology of Endothelial Cells by Eric A. Jaffe Pdf

The participation of endothelial cells in various physiologic and pathologic processes has been hypothesized since before the turn of the century. However, until recently, direct evidence for endothelial involvement in these processes has been extremely difficult to obtain due to the inability to study endothelial cell function in vitro. Though the possibility of using cultured endothelial cells to study endothelial cell function in vitro was recognized many years ago, the inability to culture unambiguously identifiable endothelial cells limited investigators in their studies of endothelial function. As a result, the field of endothelial cell biology lay relatively fallow for many years. The development in the early 1970's of routine and easily implemented methods for culturing human endothelial cells and the demonstration that cultured endothelial cells synthesized a physiologically relevant protein, Factor VIII/von Willebrand Factor, quickly changed this state of affairs. Over the following decade the scope of endothelial cell research rapidly widened, spreading in a number of directions. First, methods were developed to culture endothelial cells from a variety of species. Second, methods were developed to culture endothelial cells from different organs and types of blood vessels (arteries, veins, and capillaries) within a single species. Third, and most important, investigators began using cultured endothelial cells as tools to study the potential involvement of endothelial cells in a wide assortment of biologically interesting processes. The net result has been a tremendous increase in our understanding of endothelial cell function.

Vascular Endothelium in Health and Disease by Shu Chien Pdf

In recent years there has been rapid progress in research on vascular endothelium. This has led to significant advances in our understanding of the structure and function of vascular endothelium in health and disease, including such aspects as the permeability of endothelium in relation to its ultrastructural correlates, theoretical basis, regulatory factors, and role in atherogenesis; the interaction between endothelium and blood cells; the endothelial release and processing of a number of important physiological agents, such as eicosanoids, hemostatic factors, and histamine; the cell biology of endothelium with respect to the cytoskeletal apparatus, cell activation, and cell locomotion; and the role of endothelium in microcirculatory regulation in normal and pathophysiological circumstances. A Symposium on "Vascular Endothelium in Health and Disease" was held on August 5-6, 1987, at the Institute of Biomedical Sciences, Academia Sinica, Taipei, Taiwan, Republic of China, following the 4th World Congress for Microcirculation in Japan. Experts working on various aspects of vascular endothelium came from allover the world to participate in this two-day Symposium and gave excellent presentations. This volume, embodying the proceedings of that Symposium, is a collection of the papers given by the speakers with, in many cases, further updating and new information added subsequent to the Symposium. The Institute of Biomedical Sciences (IBMS), the site of this Symposium, is a newlJl established research institution, which has vascular endothelium as one of its areas of research emphasis.

Vascular Endothelium by J. Catravas Pdf

Beyond their obvious role of a barrier between blood and tissue, vascular endothelial cells are now firmly established as active and essential participants in a host of crucial physiological and pathophysiological functions. Probably the two most important factors responsible for promoting the current knowledge of endothelial functions are 1) observations in the late sixties-early seventies that many non-ventilatory properties of the lung could be attributed to the pulmonary endothelium and 2) the establishment, in the early and mid-seventies of procedures for routine culture of vascular endothelial cells. Many of these endothelial functions require the presence of receptors on the surface of the plasma membrane. There is now evidence for the existence among others of muscarinic, a-and /3-adrenergic, purine, insulin, histamine, bradykinin, lipoprotein, thrombin, paf, fibronectin, vitronectin, interleukin and albumin receptors. For some of these ligands, there is evidence only for the existence of endothelial binding sites. Traditionally, agonist binding must elicit a response for the binding site to be considered a receptor and, in some cases, the nature of the response resulting from the interaction of a substance with the endothelium remains unclear. It is beyond the scope of this introduction to even enumerate the various endothelial homeostatic processes. This monograph contains the proceedings of the Advanced Studies Institute on "Vascular Endothelium: Receptors and Transduction Mechanisms" held in Porto Carras, Greece from June 18-29, 1988.

The Radiation Biology of the Vascular Endothelium by David B. Rubin Pdf

Endothelial cells are early targets of radiation injury. Because these cells are tissues easily damaged by radiation, if we can understand the causes of radiation injury, then normal cells can be well protected and tumors can be destroyed. The Radiation Biology of the Vascular Endothelium brings together expert reviews on the biology and radiobiology of the vasculature, with emphasis on the endothelial cell component of blood vessels. The book covers both the basic aspects of endothelial cell biology and the practical consequences of this for the oncologist, with special reference to the radiation oncologist. After reading The Radiation Biology of the Vascular Endothelium, no clinical or experimental oncologist should be able to ignore the intimate relationship between tumor and normal tissue cells and endothelial cells that form the barrier to, and are the bearers of, essential nutrient supplies.
