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. Table of Contents: Introduction / Multiple Functions of the Endothelial Cells / Calcium Signaling in Vascular Cells and Cell-to-Cell Communications / Endothelium-Dependent Regulation of Vascular Tone / Conclusion / References

Book Description
Since the publication of my previous monograph in 1974, important progress has been made in the broad area of calcium research, partic ularly as it pertains to secretory phenomena. The significant advance in methodology, while widening the scope of our knowledge, has caused research in this particular area to become more and more specialized. It has, therefore, become increasingly difficult for researchers to consider and evaluate work outside their own areas of specialization and to com prehend the field from a broad perspective. While many valuable re views on the importance of calcium in cellular function are being pro duced, they have not attempted to pull together all of the existing knowledge into a more general narrative. This volume brings together experimental data and theories from diverse sources, and attempts to synthesize into a broad conceptual framework the massive amount of specialized information that presently exists in the general area of cal cium metabolism and the secretory process. It is impossible in a book of this length to discuss specific references in detail and still maintain readability, so generalizations must be made.

Book Description
Calcium Entry Channels in Non-Excitable Cells focuses on methods of investigating the structure and function of non-voltage gated calcium channels. Each chapter presents important discoveries in calcium entry pathways, specifically dealing with the molecular identification of store-operated calcium channels which were reviewed by earlier volumes in the Methods in Signal Transduction series. Crystallographic and pharmacological approaches to the study of calcium channels of epithelial cells are also discussed. Calcium ion is a messenger in most cell types. Whereas voltage gated calcium channels have been studied extensively, the non-voltage gated calcium entry channel genes have only been identified relatively recently. The book will fill this important niche.

Book Description
The definitive text on the key component for cell functions—intracellular calcium This comprehensive book reveals the evidence for intracellular calcium as a universal switch in all animal, plant, fungal and microbial cells. It shows how the components required for calcium signaling are named and classified; covers the technology that has been developed to study intracellular calcium; describes how calcium is regulated inside cells and how it works to trigger an event; explains the role of intracellular calcium in disease, cell injury, and cell death; reveals how many drugs work through the calcium signaling system; and demonstrates how intracellular calcium is involved in the action of many natural toxins. The book also illustrates how the intracellular calcium signaling system has evolved over millions of years, showing why it was crucial to the origin of life. Additionally, the book promotes the importance of the molecular variation upon which the intracellular calcium signalling system depends. Featuring more than 100 figures (including detailed chemical structures as well as pictures of key pioneers in the field), a bibliography of some 1000 references, and a detailed subject index, this definitive work provides a unique source of scholarship for teachers and researchers in the biomedical sciences and beyond. Emphasizes two key scientific principles—the first to show how intracellular Ca2+ acts as a switch, to activate a wide range of cellular events, and the second demonstrating how an analogue mechanism can be superimposed on such a process Written by an internationally recognized expert in the field Filled with images and references to facilitate learning Fundamentals of Intracellular Calcium is an all-important text for post-graduate students and researchers working in biomedicine and biochemistry. It is also essential for undergraduate lecturers and their students in physiology, medicine, pharmacy, and the biosciences.

Book Description
The crucial role played by calcium as a cellular messenger has become increasingly evident, as has the recognition that cells spend much energy in maintaining the cytosolic concentration of this cation both constant and low. It is thought they do this to avoid precipitating phosphate, needed as a source of bond energy and to modulate protein structure. Moreover, since calcium that does enter the cell must be disposed with, processes that utilize calcium have evolved, e.g. secretion, contraction, signaling, to name just some. New knowledge concerning the processes of cellular calcium entry, extrusion and the fate of intracellular calcium has accumulated in recent years. Much has also been learned about calcium transport by and across epithelial cells. It seems logical to think that the processes of calcium entry, extrusion and intracellular handling are similar in all cells. We have therefore assembled in one volume overviews and research reports of transport and cellular calcium regulation so as to explore similarities and differences between cells that utilize calcium for metabolic purposes and those whose primary function is transport.

Book Description
Volume 30 examines the prominent role of calcium as an intracellular second messenger. Leading investigators review a wide variety of studies on how calcium enters and moves through cells, how it interacts with its many binding proteins, and how calcium and its intracellular receptor, calmodulin, control vital cellular processes. Coverage includes a detailed analysis of the mechanisms by which calcium bound to calmodulin regulates contractile proteins in smooth muscle cells. Close attention is given to the roles of calcium and calmodulin-dependent protein kinases and phosphatases in synaptic signal transduction, protein synthesis, gene expression, programmed cell death, activation of T-lymphocytes, and control of cell division cycles. Other chapters discuss studies using genetically manipulable nonmammalian organisms to further proble the functions of calcium and calmodulin.
