Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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

Book Description
The microcirculation is highly responsive to, and a vital participant in, the inflammatory response. All segments of the microvasculature (arterioles, capillaries, and venules) exhibit characteristic phenotypic changes during inflammation that appear to be directed toward enhancing the delivery of inflammatory cells to the injured/infected tissue, isolating the region from healthy tissue and the systemic circulation, and setting the stage for tissue repair and regeneration. The best characterized responses of the microcirculation to inflammation include impaired vasomotor function, reduced capillary perfusion, adhesion of leukocytes and platelets, activation of the coagulation cascade, and enhanced thrombosis, increased vascular permeability, and an increase in the rate of proliferation of blood and lymphatic vessels. A variety of cells that normally circulate in blood (leukocytes, platelets) or reside within the vessel wall (endothelial cells, pericytes) or in the perivascular space (mast cells, macrophages) are activated in response to inflammation. The activation products and chemical mediators released from these cells act through different well-characterized signaling pathways to induce the phenotypic changes in microvessel function that accompany inflammation. Drugs that target a specific microvascular response to inflammation, such as leukocyte-endothelial cell adhesion or angiogenesis, have shown promise in both the preclinical and clinical studies of inflammatory disease. Future research efforts in this area will likely identify new avenues for therapeutic intervention in inflammation.

Book Description
A vast literature has been concerned with arteriosclerosis and yet, many aspects of pathogenesis and of the mechanism of development of the arteriosclerotic vascular lesion remain only poorly understood. In recent years, our knowledge of the earliest stages of arteriosclerosis have greatly improved. By now, we have learned to relate morphologic changes to disturbances in function. It has been of particular impor tance that components of the arterial wall could be analyzed in regard to dysfunction, for example, in the endothelium or the vascular smooth muscle. The interaction of the different morphological components of the vascular wall could thus be much bet ter understood. Likewise, the interaction between the arterial wall and the flowing blood could be much better described, including the intimate relationship between platelets and the endothelium, the coagulation system and the endothelium, the granulocytes and the endothelial cell layer, as well as processes of migration of blood cells into the subendothelial space. The recognition of functional and morphological disturbance has attained clinical significance not only because the arteriosclerotic diseases have quantitatively reached the dimensions of an epidemic, that is, of a magnitude never been witnessed. It is also because of the development of new drugs that interfere with the atherogenic process and thereby prevent the development of the disease or halt its progression. It is also becoming increasingly possible to inhibit the occurrence of complications in existing arteriosclerotic lesions in manifest disease, i. e.
