Book excerpt: The most important communication mechanism between cardiac cells is electrical transmission via low resistance pathways, the so-called gap junction channels. These gap junctions play a vital role in the physiological activation pattern and in pathophysiological cardiac conditions. This book provides a comprehensive overview of what is currently known about cardiac gap junctions, a relatively young field of research. An introduction into the various aspects of activation propagation and coupling in the heart is followed by a detailed description of the structure and diversity of gap junctions, including amino acid sequences and species variability. Subsequent chapters discuss their distribution, physiology and functions, and the regulation of expression. The author then goes on to put these basic findings into a clinical context: The changes of gap junction distribution in the course of cardiac disease and their implications receive special attention. A further chapter presents pharmacological approaches to the modulation of gap junction channel conductivity and outlines possible new therapeutic strategies. The final part of the book, especially written for scientists who intend to enter the field of cardiovascular research, describes methods of investigation including double cell voltage clamp, immunohistochemistry, isolation procedures for gap junctions and dye coupling assays. Authoritative and up-to-date, this book successfully bridges the gap between basic and clinical research. It provides an excellent introduction for newcomers to the field and will also be a valuable source of information for basic researchers, cardiologists, physiologists and pharmacologists.

Available in PDF, EPUB and Kindle. Book excerpt: Cardiac cell biology has come of age. Recognition of activated or modified signaling molecules by specific antibodies, new selective inhibitors, and fluorescent fusion tags are but a few of the tools used to dissect signaling pathways and cross-talk mechanisms that may eventually allow rational drug design. Understanding the regulation of cardiac hypertrophy in all its complexity remains a fundamental goal of cardiac research. Since the advancement of adenovirally mediated gene transfer, transfection efficiency is no longer a limiting factor in the study of cardiomyocytes. A limiting factor in considering cell transplantion as a strategy to repair the damaged heart is cell availability at the right time. Cardiac gap junctions, intercellular communication channels that allow electrical and metabolic coupling and play an important role in arrhythmogenesis are now understood to be exquisite sensors of cardiac change. The reports in this volume incLude elegant studies that made use of cutting edge technological advances and many specialized reagents to address these issues.

Download or read book Gap Junctions in Development and Disease written by Elke Winterhager and published by Springer Science & Business Media. This book was released on 2005-11-04 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Communication between cells via intercellular channels – gap junctions – appears essential to certain developmental processes and appropriate organ function. Gap Junctions in Development and Disease aims to describe the molecular events underlying impaired development and disease. Beginning with a comprehensive review of various mouse and human genes encoding the channel-forming connexins, later chapters describe several connexin mutations associated with human diseases such as hereditary deafness and female infertility. Erroneous signaling mediated by the interaction of mutant connexins with other proteins, thought to be responsible for dysfunction of organs such as heart, muscle, brain, skin, lens, placenta, and endocrine tissue in both mice and men, is also addressed. Although the question of why some mutations in gap-junction proteins lead to specific phenotypes remains to be answered, the reviews in this book provide an intriguing insight into the future direction of this research field.

Download or read book Gap Junction Mediated Intercellular Signalling in Health and Disease written by Gail Cardew and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gap junctions are key elements in communication between cells in multicellular organisms. It is clear that their activity is essential for normal embryonic development and normal function in adult organs, although the individual roles of the proteins that form the channels (connexins) are not yet fully understood. The last few years have seen considerable progress in this field and exciting new issues concerning gap junctional intercellular communication are being raised. Perturbed gap junction activity is beginning to be linked to certain pathologies, e.g. mutations in the major connexin of the heart have been found in human patients suffering from visceroatrial heterotaxia syndrome and mutations in the gene encoding another connexin have been found in patients with Charcot-Marie-Tooth disease. This book is the first to highlight the recent progress in understanding gap junction structure and to discuss the specific roles of individual connexins. It features contributions from an interdisciplinary group of experts who review the role of gap junctions in the heart, the retina and lens, the auditory system, the reproductive system, and in cell proliferation and cancer. The book will appeal to people interested in cell and molecular biology, embryonic development, neurobiology, cardiology, gynaecology and oncology.
Download or read book Gap Junctions Molecular Basis of Cell Communication in Health and Disease written by and published by Academic Press. This book was released on 1999-12-22 with total page 681 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first gap junction protein (connexin) was cloned over a decade ago, more than a dozen connexin genes have been cloned. Consequently, a wealth of information on the molecular basis of gap junctional communication has been accumulated. This book pays tribute to this exciting era in the history of cell communication research by documenting the great strides made in this field as a result of the merging of biophysics and molecular biology, two of the most powerful approaches to studying the molecular basis of membrane channel behavior. Twenty-eight comprehensive chapters, authored by internationally recognized leaders in the field, discuss the biophysical, physiological, and molecular characteristics of cell-to-cell communication via gap junctions. Key aspects of molecular structure, formation, gating, conductance, and permeability of vertebrate and invertebrate gap junction channels are highlighted. In addition, a number of chapters focus on recent discoveries that implicate connexin mutations and alterations of gap junctional communication in the pathogenesis of several diseases, including the X-linked Charcot Marie Tooth demyelinating disease, some forms of inherited sensorineural deafness, malignant transformation, cardiac malformations and arrhythmia, eye lens cataract, and Chagas' disease.
Download or read book Heart Cell Communication in Health and Disease written by Walmor C. de Mello and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Heart Cell Communication in Health and Disease an extensive review of different aspects of heart cell communication is presented. The book starts with the fundamental concept that cardiac cells are communicated, and then proceeds to the role of gap junctions in heart development, the molecular biology of gap junctions, the biophysics of the intercellular channels, the control of junctional conductance and the influence of gap junctions on impulse propagation. This is the first time that a single volume has described cell communication in the normal heart and under different pathological conditions such as heart failure, coronary disease, myocardial ischemia and cardiac arrhythmias. In this way the process of cell communication is analyzed at different levels of complexity, providing the reader with a wide view of this field and its relevance to cardiology.
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 Tissue Oxygenation Second Edition written by Roland N. Pittman and published by Biota Publishing. This book was released on 2016-08-18 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
