The Endothelium, Part I 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.

The Endothelium, Part II by Michel F. L. Tou,Michel Félétou Pdf

The endothelium controls vascular tone by releasing various vasoactive substances. Additionally, another pathway associated with the hyperpolarization of both endothelial and vascular smooth muscle cells contributes also to endothelium-dependent relaxations (EDHF-mediated responses). These responses involve an increase in the intracellular Ca concentration of the endothelial cells followed by the opening of Ca-activated K channels of small and intermediate conductances (SKCa and IKCa). These channels show a distinct subcellular distribution, suggesting that their activation could be elicited by distinct stimuli. Following KCa activation, the endothelial hyperpolarization can be conducted to the underlying smooth muscle cells by electrical coupling through myo-endothelial gap junctions. In addition, the potassium efflux can lead to the accumulation of potassium ions in the intercellular space and the subsequent activation of smooth muscle Kir2.1 and/or Na/K-ATPase. The hyperpolarization of the smooth muscle cells produces vascular relaxation, predominantly by closing voltage-gated calcium channels, and vasodilatation. EDHFmediated responses are altered in various pathologies or, conversely, act as a compensating mechanism when other endothelial pathways are impaired. A better characterization of EDHF-mediated responses should allow determining whether or not new drugable targets can be identified within this endothelial pathway for the treatment of cardiovascular diseases.

Endothelial Biomedicine by William C. Aird Pdf

The endothelium, the cell layer that forms the inner lining of blood vessels, is a spatially distributed system that extends to all areas of the human body. Clinical and basic research demonstrates that the endothelium plays a crucial role in mediating homeostasis and is involved in virtually every disease, either as a primary determinant of pathophysiology or as a victim of collateral damage. The endothelium has remarkable, though largely untapped, diagnostic and therapeutic potential. This volume bridges the bench-to-bedside gap in endothelial biomedicine, advancing research and development and improving human health. The book is the first to systematically integrate knowledge about the endothelium from different organ-specific disciplines, including neurology, pulmonary, cardiology, gastroenterology, rheumatology, infectious disease, hematology-oncology, nephrology, and dermatology. It's interdisciplinary approach, which draws on expertise from such diverse fields as evolutionary biology, comparative biology, molecular and cell biology, mathematical modeling and complexity theory, translational research, and clinical medicine.

Modern Visualisation of the Endothelium by J M Polak Pdf

There can no longer be any doubt that the endothelium represents a very active tissue and is not, as had previously been thought, merely an inert lining material. On the contrary, the endothelium exerts a powerful influence on its environs through the release of multiple regulatory factors such as nitric oxide, endothelium derived hyperpolarizing factor and endothelin. It is therefore crucial to our understanding of the cardiovascular system that we are able to visualize the endothelial layer at the molecular level. Quantitative morphological studies permit visualization at this level, allowing the assessment of the changes that occur in the disease state. Modern methods of computerized image analysis have been applied to reconstruct the endothelial layer in three-dimensions - detecting even the most subtle of changes. Within these covers, an integrated text has been gathered by experts in each of their fields. They detail the latest technical and conceptual advances in the visualization of endothelium, its production of regulatory molecules and pathological changes.

Endothelial Dysfunction by Helena Lenasi Pdf

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.

Endothelial Luminal Membrane-Glycocalyx by Rafael Rubio,Maureen Knabb Pdf

This book focuses on the structural, biochemical, and diverse functional properties of the endothelial luminal membrane glycocalyx (ELMG), an organelle which constitutes the endothelial cell "membrane." It is intended to provide the newcomer with a broad, basic, and brief perspective of the luminal endothelial vascular membrane, and for the more established investigator, a basic overview and integrated perspective of the "universe" we explore. The endothelium is an assortment of heterogeneous regulatory cells whose cytoplasm and cell membranes are joined, forming functional units. There is a tremendous amount of literature on the endothelial cell, constituting seemingly isolated and distinct fields of encapsulated research. However, the multifunctional properties of some molecules give rise to an overlap of findings, frequently ignored between the different fields. The book is divided into three parts. The first part concentrates on the structure of the ELMG, with emphasis on morphological and biochemical composition. The importance of the chemical composition to the physiological functions of the ELMG, such as sieving properties, pharmacology, and flow sensing, is the focus of the second part of the book. Finally, some of the pathologies associated with ELMG dysfunction are explored in the last section. The aim is to provide basic and well-established knowledge in the various individual fields, identify the current concepts in each area, and discuss their respective strengths and weaknesses (including hidden problems). Finally, the overall goal is to integrate areas where overlap is clearly indicated, bringing them all together to provide the first ever basic, integrative, panoramic bird’s-eye view of the field.
