This book was released on 2013-10-30 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the role calcium signaling plays in cellular responses in almost all types of cells including airway smooth muscle cells. This universal signaling may result from extracellular calcium influx and/or intracellular calcium release, which are precisely controlled and regulated by ion channels, exchangers and/or transporters on the plasmalemmal or sarcoplasmic reticulum membrane. First, several chapters detail calcium release channels (ryanodine receptors and inositol trisphosphate receptors), voltage-dependent potassium channels, transient receptor potential channels, Orai channels, calcium-activated potassium channels, and calcium-activated chloride channels. Well-characterized sodium-calcium exchangers, voltage-dependent calcium channels, and calcium pumps are described also in depth over many chapters. Ca2+ signaling can be expressed in Ca2+ sparks, waves, oscillations, and global changes in intracellular Ca2+ concentration. Calcium in subcellular compartments (cytosol, sarcoplasmic reticulum, mitochondria, and caveolae) also exhibit dynamic crosstalk. Many molecules including FK506 binding proteins, cyclic adenosine diphosphate ribose, reactive oxygen species, RhoA kinases, caveolin and integrins can modify and induce spatial, temporal and compartmental variations of calcium signaling. In addition, calcium signaling can exhibit sex hormone- and age-dependent changes. A number of chapters are dedicated to covering these diverse formats, spatiotemporal characteristics, multifaceted network and mathematical modeling of Ca2+ signaling. Neurotransmitters, hormones, growth factors, inflammatory cytokines, and other stimuli may lead to multiple cellular responses by inducing Ca2+ signaling in airway smooth muscle cells. Increasing evidence suggests that Ca2+ pumps and canonical transient receptor potential channels are essential for airway smooth muscle remodeling. Accordingly, several chapters summarize recent advances in the studies of the key role of calcium signaling in physiological cellular responses as well as the development of asthma, chronic obstructive pulmonary disease and other respiratory disorders.

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.

Download or read book Calcium in Muscle Activation written by Johann C. Rüegg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comparative and interdisciplinary approach to excitation-contraction-coupling in smooth and striated mus cles, including the myocardium. It is an account of the path ways and mechanisms by which cellular calcium is handled and activates the contractile proteins. It also describes how these mechanisms are adapted in various kinds of muscle to meet specific functional requirements, such as speed or economy. This monograph then presents facts, ideas and theories and the evidence on which they are based, and ifit stimulates others and furthers research, it will have served its purpose. All of the chapters are self-contained and may be read in any order, but readers unfamiliar with muscle are recommended to start with the introductory chapter on excitation and contraction. During all the years of writing this book, I received enormous help from Isolde Berger who corrected, edited and transformed my innumerable notes and drafts into a readable manuscript; she also compiled the list of references and the Subject Index. I owe a great debt of gratitude to her and also to Claudia Zeugner, who prepared the figures with expertise and care. Then I would like to thank the Deutsche F orschungs gemeinschaft and the Fritz-Thyssen-Stiftung for supporting the work of my Department which has been reported in this monograph. A great many people contributed with helpful discussions.

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 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.
