Endothelial Signalling In Vascular Dysfunction And Disease

Endothelial Signaling in Vascular Dysfunction and Disease: From Bench to Bedside provides a detailed understanding of the endothelium, its activation and their link to some common clinical disorders. In addition, the book covers earlier discoveries, including those from the last and 19th centuries. It is split into five sections that cover the vascular tree as an integrative structure, the endothelium in inflammation, endothelial signaling, activation and toxicity with chemotherapy, radiation induced endothelial dysfunction and vascular disease, and therapies in combating vascular diseases. Each section is discussed with a translational approach in order to make the content truly applicable. This book is a valuable source for basic researchers, clinicians in the fields of Oncology, Cardiovascular Medicine and Radiology, and members of the biomedical field who are conducting studies related to the endothelium and vascular disease. Discusses the most relevant discoveries in endothelial biology and their link to manifestations of clinical disease Presents history and diagrams in each section to highlight the original biological discovery and its link of clinical manifestations of vascular disease Includes recent findings on the relationship between endothelial signaling, chemotherapy and radiation induced endothelial dysfunction

This book surveys healthy and diseased vascular systems in a multitude of model organisms and systems. It explores a plethora of functions, characteristics, and pathologies of the vascular system such as angiogenesis, fibroblast growth factor signaling, lymphangiogenesis, junctional signaling, the extracellular matrix, vascular permeability, leukocyte extravasation, axon guidance factors, the angiopoietin system, and chronic obstructive lung disease. Following a preface from leading researcher Dr. Holger Gerhardt, the text is divided into three sections- the first examining the development of the vascular system in a variety of contexts, the second delving into its homeostatic characteristics, and the third discussing its pathophysiologies. The sixteen chapters, which represent international clinical and research perspectives, highlight the importance of molecular and signaling pathways for translational basic science and clinical medicine. Additionally, the text explores new and exciting fields in vascular biology research. Comprehensive in both content and approach, Vascular Signaling in Health and Disease is ideal for graduate students, researchers, and clinicians interested in vascular biology, pneumology, and molecular biology.

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.

The endothelium enables communication between blood and tissues and is actively involved in cardiovascular homeostasis. Endothelial dysfunction has been recognized as an early step in the development of cardiovascular diseases: respectively, endothelium represents a potential therapeutic niche with multiple targets. The purpose of the book is to point out some recent findings of endothelial physiology and pathophysiology emphasizing various aspects of endothelial dysfunction connected to the body's internal and external environment. While basic features of the endothelium are presented in an introductory chapter, the authors of the following 17 chapters have provided extensive insight into some selected topics of endothelial (dys)function. The book would hopefully be useful for anyone interested in recapitulating endothelial (patho)physiology and expanding knowledge of molecular mechanisms involved in endothelial dysfunction, relevant also for further clinical investigations.

New updated edition first published with Cambridge University Press. This new edition includes 29 chapters on topics as diverse as pathophysiology of atherosclerosis, vascular haemodynamics, haemostasis, thrombophilia and post-amputation pain syndromes.

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.

Endothelial dysfunction is broadly defined as a disruption of the balance between vasoactive mediators and a propensity towards an inflammatory state. This volume provides an overview of the fields of endothelial dysfunction and inflammation through the discussion of topics ranging from the molecular biology of activated endothelial cells to the endothelium in inflammatory disease and therapeutic approaches targeting endothelial dysfunction. Topics include: Heterogeneity of the endothelium during inflammation, oxidative stress and endothelial dysfunction, biology and regulation of nitric oxide in inflammatory pathologies, endothelial dysfunction in inflammatory diseases, such as diabetes and atherosclerosis and Clinical methods used to assess endothelial function. This book brings together basic and clinical research to assist the reader in bridging connections from bench-to-bedside. Written by expert researchers in the fields of endothelial biology, inflammation research and clinical science, it serves as a useful reference for academic and industrial researchers, clinicians, and trainees in the medical profession.
