Download or read book Calcium Entry Channels in Non Excitable Cells written by Juliusz Ashot Kozak and published by CRC Press. This book was released on 2017-07-14 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Endothelium written by Michel Félétou and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Vascular Ion Channels in Physiology and Disease written by Irena Levitan, PhD and published by Springer. This book was released on 2016-07-06 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion channels are the major class of membrane proteins responsible for rapid and regulated transport of ions across biological membranes and for the generation and propagation of electrical signals in the brain, heart, and skeletal and vascular tissues. Ion channels are also known to play critical roles in regulation of cell proliferation, insulin secretion and intracellular signaling in a variety of cell types. This book focuses on the roles of ion channels in vascular tissues under normal and pathological conditions. Vascular abnormalities are known to underlie a plethora of severe pathological conditions, such as atherosclerosis, systemic and pulmonary hypertension, coronary or cerebral vasospasm, and diabetes. In addition, misregulated angiogenesis is one of the major contributors to the development of tumors. Therefore, it is clearly imperative to obtain a better understanding of the molecular mechanisms that contribute to vascular disorders. This book will be the first comprehensive assembly of assays to present the studies that have been done during the last decade to elucidate the roles of ion channels in different vascular diseases.
Download or read book Regulation of Vascular Smooth Muscle Function written by Raouf A. Khalil and published by Biota Publishing. This book was released on 2010-05-01 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vascular smooth muscle (VSM) constitutes most of the tunica media in blood vessels and plays an important role in the control of vascular tone. Ca2+ is a major regulator of VSM contraction and is strictly regulated by an intricate system of Ca2+ mobilization and Ca2+ homeostatic mechanisms. The interaction of a physiological agonist with its plasma membrane receptor stimulates the hydrolysis of membrane phospholipids and increases the generation of inositol 1,4,5-trisphosphate (IP3) and diacylglycerol (DAG). IP3 stimulates Ca2+ release from the intracellular stores in the sarcoplasmic reticulum. Agonists also stimulate Ca2+ influx from the extracellular space via voltage-gated, receptor-operated, and store-operated channels. Ca2+ homeostatic mechanisms tend to decrease the intracellular free Ca2+ concentration ([Ca2+]i) by activating Ca2+ extrusion via the plasmalemmal Ca2+ pump and the Na+/Ca2+ exchanger and the uptake of excess Ca2+ by the sarcoplasmic reticulum and possibly the mitochondria. A threshold increase in [Ca2+]i activates Ca2+-dependent myosin light chain (MLC) phosphorylation, stimulates actin–myosin interaction, and initiates VSM contraction. The agonist-induced maintained increase in DAG also activates specific protein kinase C (PKC) isoforms, which in turn cause phosphorylation of cytoplasmic substrates that increase the contractile myofilaments force sensitivity to Ca2+ and thereby enhance VSM contraction. Agonists could also activate Rho kinase (ROCK), leading to inhibition of MLC phosphatase and further enhancement of the myofilaments force sensitivity to Ca2+. The combined increases in [Ca2+]i, PKC and ROCK activity cause significant vasoconstriction and could also stimulate VSM hypertrophy and hyperplasia. The protracted and progressive activation of these processes could lead to pathological vascular remodeling and vascular disease.

This book was released on 2002-08-02 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smooth muscle contraction is a vital component of the functioning of blood vessels, the uterus, airways and the bladder. Its malfunction can lead to serious pathological conditions, such as hypertension and pre-term labour. The calcium ion plays a central role in smooth muscle function, increasing in concentration for contraction and decreasing for relaxation. Calcium entry into the cell is facilitated by the sarcoplasmic reticulum (SR). This book explores the latest research on the role of the sarcoplasmic reticulum (SR) in smooth muscle function. It examines the control and modulation of the SR and how this may vary among smooth muscle types. Potential therapeutic implications are also discussed. Discusses new and exciting work in this area and identifies promising new research directions. Considers the advances in this relatively unexplored field, offering new insights into the role of the SR muscle. Brings together contributions from key workers, both in basic and clinical science, whose studies range from physiological to pathological and molecular to whole animal.

Download or read book Calcium and Contractility written by A. K. Grover and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: In organizing the present volume, we had two intentions. The first was to present the best current understanding of the mechanisms of calcium mobilization during excitation contraction coupling of smooth muscle at a level suited to the needs of professionals interested in smooth muscle pharmacology and pathophysiology, while remaining appreciable by graduate and medical students. The second intention was to provide in sight into present-day controversies, as well as the latest ad vances achieved by researchers in this field. Thus, we have thor oughly discussed both the techniques and the concepts derived from their application. An attempt has also been made here to answer a number of profoundly important questions: What are the mechanisms and agents responsible for the control of contractility? What are the accompanying changes in the state of intracellular calcium ions and the mechanisms responsible for them? How does the regula tion of contractility occur directly at the level of the actomyosin activity? What role do gap junctions play in cell-to-cell coupling? What are the roles of cholinergic, adrenergic, peptidergic, and nonadrenergic noncholinergic interactions in calcium mobiliza tion in smooth muscle? What changes occur in hypertension? The impact of these recent techniques on future research is also reflected upon.
