Download or read book Gap Junction Channels and Hemichannels written by Taylor & Francis Group and published by CRC Press. This book was released on 2021-03-30 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gap junction channels are a group of intercellular channels expressed in tissues and organs to synchronize many physiological processes. A gap junction channel is formed by the docking of two hemichannels, and each hemichannel is a hexamer of connexins. The field of gap junction channel and hemichannel research has recently exploded and became one of the most active areas of cell biology. Numerous novel approaches and techniques have been developed, but there is no single book dedicated to the unique techniques and protocols employed for the research on these large pore channels. This book fills the gap and focuses on protocols, approaches and reviews of gap junction channels and connexin hemichannels. It will be a useful reference for graduate students, postdoctoral fellows and researchers. Anyone with an interest in gap junction channels and hemichannels will need this summary of state-of-the-art techniques and protocols.

Download or read book Enteric Glia written by Brian D. Gulbransen and published by Biota Publishing. This book was released on 2014-07-01 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The enteric nervous system (ENS) is a complex neural network embedded in the gut wall that orchestrates the reflex behaviors of the intestine. The ENS is often referred to as the “little brain” in the gut because the ENS is more similar in size, complexity and autonomy to the central nervous system (CNS) than other components of the autonomic nervous system. Like the brain, the ENS is composed of neurons that are surrounded by glial cells. Enteric glia are a unique type of peripheral glia that are similar to astrocytes of the CNS. Yet enteric glial cells also differ from astrocytes in many important ways. The roles of enteric glial cell populations in the gut are beginning to come to light and recent evidence implicates enteric glia in almost every aspect of gastrointestinal physiology and pathophysiology. However, elucidating the exact mechanisms by which enteric glia influence gastrointestinal physiology and identifying how those roles are altered during gastrointestinal pathophysiology remain areas of intense research. The purpose of this e-book is to provide an introduction to enteric glial cells and to act as a resource for ongoing studies on this fascinating population of glia. Table of Contents: Introduction / A Historical Perspective on Enteric Glia / Enteric Glia: The Astroglia of the Gut / Molecular Composition of Enteric Glia / Development of Enteric Glia / Functional Roles of Enteric Glia / Enteric Glia and Disease Processes in the Gut / Concluding Remarks / References / Author Biography
Download or read book Gap Junctions Molecular Basis of Cell Communication in Health and Disease written by Dale J. Benos and published by Gulf Professional Publishing. This book was released on 1999-12-14 with total page 692 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 Intercellular Communication in Cancer written by Mustapha Kandouz and published by Springer. This book was released on 2015-11-20 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cells are by nature compelled to live in groups. They develop dependence over signaling cues received from their microenvironment, in particular from other cells, whether of their own “kind” or of a different type. Therefore, communicating with these cells is a critical aspect of their behavior and fate, as they live and die normally or as they undergo disease-related pathological changes, with dramatic repercussions. In this book, we have asked expert researchers in the field of Intercellular Communication in Cancer to provide chapters on different aspects of interaction between neighboring cells, in the context of cancer diseases. We have specifically focused our efforts on membrane-to-membrane contact-based rather than growth factors-mediated modes of intercellular communications. The contributing authors provide an extensive overview of their respective area of specialization, with an in-depth discussion of the molecular mechanisms of cell-cell interactions, the impact on tumor progression and response to therapies, as well as the cancer diagnostic value of this scientific information. This book aims to introduce essential aspects of the normal and pathological cellular fate and homeostasis to both scientists and clinicians, and also to provide established researchers with an update on the novelties and future directions this expanding field is witnessing.
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 2005-07-19 with total page 312 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 Hemichannels from the molecule to the function written by Mauricio Antonio Retamal and published by Frontiers Media SA. This book was released on 2015-04-17 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coordinated cell interactions are required to accomplish several complex and dynamic tasks observed in several tissues. Cell function may be coordinated by cell-to-cell communication through gap junctions channels (GJCs). These channels are formed by the serial docking of two hemichannels, which in turn are formed by six protein subunits called connexins (Cxs). It is well known that GJCs are involved in several functions, such as intercellular propagation of calcium waves, spread of electrotonic potentialsand spatial buffering of ions and metabolites. On the other hand, undocked hemichannels, which are not forming GJCs, can also serve other functions as “free hemichannels”. Currently, it is recognized that undocked hemichannels may have functional relevance in cell physiology allowing diffusional exchange of ions and small molecules between intra- and extra-cellular compartments. Additionally, another family of proteins calls pannexins (Panx) also forms functional hemichannels at the plasma membrane. Recently, Panxhemichannels have been involved in both pathological and physiological processes. Controlled hemichannel opening allows the release of small signaling molecules including ATP, glutamate, NAD+, adenosine, cyclic nucleotides, PGE2. They also allow uptake of relevant signaling molecules (e.g., cADPR) and metabolites (e.g., glucose). Additionally, a growing body of evidence shows that hemichannels are involved in important processes, such glucose detection in tanicytes, activation of the inflammasome, memory consolidation in the basolateral amygdala, potentiation of muscle contraction and release of nitric oxide from endothelial cells, among others. However, hemichannels can also play an important role in the homeostatic imbalance observed in diverse chronic diseases. In fact, massive and/or uncontrolled hemichannel opening induces or accelerates cell death in several pathological conditions including Charcot-Marie-Tooth disease, ischemia, oculodentodigital dysplasia, hydrotic ectodermic dysplasia, inflammatory responses, and deafness. Hemichannel-mediated cell death is due mainly to an entry of Ca+2. The latter activates proteases, nucleases and lipases, causing irreversible cell damage. An increasing amount of evidence demonstrates that blockade of uncontrolled hemichannel opening greatly reduces the cellular damage observed in several chronic diseases models. Therefore, Cx and Panx-hemichannels appear as promising drug targets for clinical treatment of human chronic diseases. Therefore, pharmacological tools are urgently needed to further elucidate hemichannels functions and to validate them as drug targets for the development of novel therapies for connexin-based diseases. Thus, understanding the role of Cx and Panx-hemichannels under physiological conditions and recognizing the molecular mechanisms controlling them, may provide us with a better picture of the hemichannels participation in some diseases and of the signals underlying their malfunctioning.
Download or read book Astrocytes and Epilepsy written by Jacqueline A. Hubbard and published by Academic Press. This book was released on 2016-07-05 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epilepsy is a devastating group of neurological disorders characterized by periodic and unpredictable seizure activity in the brain. There is a critical need for new drugs and approaches given than at least one-third of all epilepsy patients are not made free of seizures by existing medications and become "medically refractory". Much of epilepsy research has focused on neuronal therapeutic targets, but current antiepileptic drugs often cause severe cognitive, developmental, and behavioral side effects. Recent findings indicate a critical contribution of astrocytes, star-shaped glial cells in the brain, to neuronal and network excitability and seizure activity. Furthermore, many important cellular and molecular changes occur in astrocytes in epileptic tissue in both humans and animal models of epilepsy. The goal of Astrocytes and Epilepsy is to comprehensively review exciting findings linking changes in astrocytes to functional changes responsible for epilepsy for the first time in book format. These insights into astrocyte contribution to seizure susceptibility indicate that astrocytes may represent an important new therapeutic target in the control of epilepsy. Astrocytes and Epilepsy includes background explanatory text on astrocyte morphology and physiology, epilepsy models and syndromes, and evidence from both human tissue studies and animal models linking functional changes in astrocytes to epilepsy. Beautifully labelled diagrams are presented and relevant figures from the literature are reproduced to elucidate key findings and concepts in this rapidly emerging field. Astrocytes and Epilepsy is written for neuroscientists, epilepsy researchers, astrocyte investigators as well as neurologists and other specialists caring for patients with epilepsy. Presents the first comprehensive book to synthesize historical and recent research on astrocytes and epilepsy into one coherent volume Provides a great resource on the field of astrocyte biology and astrocyte-neuron interactions Details potential therapeutic targets, including chapters on gap junctions, water and potassium channels, glutamate and adenosine metabolism, and inflammation
