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.

Pericytes were originally discovered and named more than hundred years ago as contractile cells around the blood vessel endothelial cells. Due to the lack of exclusive markers, pericytes are now defined by a combination of location, morphology and gene expression. Pericytes are attracting increasing attention as important regulators during development and during normal and disturbed organ function. In recent years, remarkable progress has been made in the identification and characterization of pericytes subpopulations and their amazing functions using state-of-art techniques. These advantages facilitated identification of molecular basis of interaction between these cells with several other more well studied cell types, and revealed key signals derived from pericytes involved in homeostasis, regeneration, and disease regulation. In the last ten years, several unexpected roles of pericytes have been discovered. It has been demonstrated that pericytes from different tissues differ in their properties as well as functions. Even more, pericytes are heterogeneous also within the same organ. This book is will describe the major contributions of pericytes to different organs biology in physiological and pathological conditions. The book will teach the readers about this so special cell type that 10 years ago was almost completely forgotten, and it was associated basically only with vascular stability. Recently, it become a very hot topic to work in. Several articles in Nature, Science and Cell have been and are being currently published about this cell type. These recent works are revealing how important those cells are for before unimaginable biological processes. Thus, this book will update us on what are the most novel functions attributed to these cells. Also, will introduce to the young generation all the history about these cells from when they were discovered in different organs till where we are now in this field. So it will be a great book for both cell biology students as well as researchers that will have an update on these cells biology in different organs.

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.

"This volume is a very valuable and much needed contribution." –Quarterly Review of Biology AT LAST - A comprehensive, accessible textbook on glial neurobiology! Glial cells are the most numerous cells in the human brain but for many years have attracted little scientific attention. Neurophysiologists concentrated their research efforts instead, on neurones and neuronal networks because it was thought that they were the key elements responsible for higher brain function. Recent advances, however, indicate this isn’t exactly the case. Not only are astroglial cells the stem elements from which neurones are born, but they also control the development, functional activity and death of neuronal circuits. These ground-breaking developments have revolutionized our understanding of the human brain and the complex interrelationship of glial and neuronal networks in health and disease. Features of this book: an accessible introduction to glial neurobiology including an overview of glial cell function and its active role in neural processes, brain function and nervous system pathology an exploration of all the major types of glial cells including: the astrocytes, oligodendrocytes and microglia of the ACNS and Schwann cells of the peripheral nervous system; the book also presents a broad overview of glial receptors and ion channels an investigation into the role of glial cells in various types of brain diseases including stroke, neurodegenerative diseases such as Alzheimer's, Parkinson's and Alexander's disease, brain oedema, multiple sclerosis and many more a wealth of illustrations, including unique images from the authors' own libraries of images, describing the main features of glial cells Written by two leading experts in the field, Glial Neurobiology provides a concise, authoritative introduction to glial physiology and pathology for undergraduate/postgraduate neuroscience, biomedical, medical, pharmacy, pharmacology, and neurology, neurosurgery and physiology students. It is also an invaluable resource for researchers in neuroscience, physiology, pharmacology and pharmaceutics.

In the last several years, the development of reagents that recognize smooth muscle-specific proteins has enabled researchers to identify smooth muscle cells (SMC) in tissue undergoing both differentiation and repair. These developments have led to increased research on SMC. The latest volume in the Biology of the Extracellular Matrix Series takes a current and all-encompassing look at this growing area of research. Devoted entirely to the subject of SMC, the book covers a diversity of topics-from SMC architecture and contractility to differentiation and gene expression in development. It also examines the proliferation and replication of SMC and its role in pharmacology and vascular disease. A must for cell, developmental, and molecular biologists, this book also will appeal to cardiologists, pathologists, and biomedical researchers interested in smooth muscle cells. - Presents a molecular, genetic, and developmental perspective of the vas smooth muscle cell - Overview sections highlight key points of chapters, including the clinical relevance of the research and expectations for future study - Appeals to both the basic biologist and to the biomedical researcher of vascular disease
