Book Synopsis Voltage Gated Sodium Channels by : Peter C. Ruben
Download or read book Voltage Gated Sodium Channels written by Peter C. Ruben and published by Springer Science & Business Media. This book was released on 2014-04-15 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of techniques to study ion channels have been developed since the electrical basis of excitability was first discovered. Ion channel biophysicists have at their disposal a rich and ever-growing array of instruments and reagents to explore the biophysical and structural basis of sodium channel behavior. Armed with these tools, researchers have made increasingly dramatic discoveries about sodium channels, culminating most recently in crystal structures of voltage-gated sodium channels from bacteria. These structures, along with those from other channels, give unprecedented insight into the structural basis of sodium channel function. This volume of the Handbook of Experimental Pharmacology will explore sodium channels from the perspectives of their biophysical behavior, their structure, the drugs and toxins with which they are known to interact, acquired and inherited diseases that affect sodium channels and the techniques with which their biophysical and structural properties are studied.

Book Synopsis Cell Type Specific Spatial and Functional Coupling Between Mammalian Brain Kv2.1 K+ Channels and Ryanodine Receptors by : Danielle Nicole Mandikian
Download or read book Cell Type Specific Spatial and Functional Coupling Between Mammalian Brain Kv2.1 K+ Channels and Ryanodine Receptors written by Danielle Nicole Mandikian and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Communication between neurons is a result of complex signaling networks. At the heart of this vast network is an intricate repertoire of ion channels whose activity give rise to directed cellular function. In order for these signaling events to occur, ion channels must be trafficked to the correct subcellular domains and function properly once there. A major mechanism to regulate this is through dynamic post translational modifications and the formation of multi protein complexes that regulate the microenvironments in which these proteins function. Voltage gated potassium channels (Kv channels) are crucial molecules that control electrical signaling by establishing membrane resting potential, frequency and duration of action potentials as well as control the release of neurotransmitters. The diversity observed in these channels are attributable to the subunits expressed as well as post-translational modifications and signaling complexes which characteristically modulate function. One broadly expressed subunit, Kv2.1, has been found to be expressed in many neuron classes throughout the brain. Kv2.1 has been shown to play a key role in homeostatic regulation of neuronal intrinsic excitability in multiple neuron classes. Phosphorylation at more than 30 sites on the c-terminus of Kv2.1 have been shown to regulate localization as well as activation of the channel. Recently Kv2.1 has also been shown to be SUMOylated, resulting in similar functional consequence as phosphorylation. To date, little is known about the complete network of Kv2.1 modifications in terms of cross talk, as well as molecular complexes that form with Kv2.1 throughout the brain which might regulate this. In Chapter 1, I introduce Kv2.1 and what is known about mechanisms which regulate its activity, In Chapter 2, I review the role of phosphorylation and SUMOylation in the regulation of Kv2.1 activity. In Chapter 3, I present unpublished work detailing the spatial and functional coupling between mammalian brain Kv2.1 and Ryanodine Receptors in a cell type specific manner. In Chapter 4, I discuss questions that arise about the nature and functional consequences of the association between Kv2.1 and RyR.
Book Synopsis Calcium Entry Channels in Non-Excitable Cells by : Juliusz Ashot Kozak
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.
Book Synopsis Ion Channels from Mammalian Brain and Heart, Incorporated Into Planar Lipid Bilayers: Regulation by Membrane Potential, Calcium, and Neurotoxins by :
Download or read book Ion Channels from Mammalian Brain and Heart, Incorporated Into Planar Lipid Bilayers: Regulation by Membrane Potential, Calcium, and Neurotoxins written by and published by . This book was released on 1983 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sodium channels and calcium channels from rat brain membranes, have been incorporated into planar phospholipid bilayer membranes and characterized electrophysiologically. Currents through many channels (macroscopic currents) and those through single channel molecules (single channel currents) were studied. The sodium channels were activated by the neurotoxin batrachotoxin, and were selective for sodium over potassium, cesium, and chloride. They opened as the membrane was depolarized, and were blocked by nanomolar concentrations of the neurotoxins saxitoxin (STX) and tetrodotoxin (TTX). The single channel conductance was 30 pS in symmetrical 0.5 M NaCl, 0.1 mM CaCl2. Block of single sodium channels by STX was found to be dependent on the membrane potential with depolarizing potentials reducing the potency of STX block by as much as 50-fold. Both blocking and unblocking rate constants were affected by the membrane potential: depolarization decreased the rate (probability) of channel block by STX and increased the rate (probability) of unblock. These sodium channels are responsible for depolarizing phase of the action potential in nerve and muscle cells and appear to be constitute the sole site of action of STX and TTX. Originator furnished keywords include: Membranes, ion channels, single channel, sodium, calcium, electrophysiology, saxitoxin, tetrodotoxin, batrachotoxin, neurotoxins, Gonyalux.
Download or read book Ion Channels written by James N. C. Kew and published by . This book was released on 2010 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion channels are intimately involved in the everyday physiological functions that enable us to live a full and varied life. When disease strikes, malfunction of ion channels or their dependent is often involved, either as the cause or the effect of the illness. Thus, billions of dollars have been, and still are being, invested in research to understand the physiological and pathophysiological functions of ion channels in an attempt to develop novel therapeutic treatments for a wide range of diseases. This book provides a comprehensive overview of ion channel structure and function. It comprises two major parts. Part one is an introductory overview of the ion channel superfamily and the generic aspects of ion channel function. This part also reviews the methodologies by which ion channel function can be studied from the perspective of performing detailed biophysical characterization through to the deployment of high throughput approaches for identifying novel ion channel ligands. Part two of the book provides an in-depth review of the individual ion channel subfamilies and, as such, is subdivided into four broad sections: Voltage-Gated Ion Channels, Extracellular Ligand-Gated Ion Channels, Intracellular Ligand-Gated Ion Channels, and Polymodal-Gated Ion Channels, with each chapter focused on specific family members. These chapters have been written by world leading experts and provide a detailed overview of the structure, biophysics, localization, pharmacology, physiology, and disease relevance of each particular ion channel subfamily. Reviewing both the basic principles of ion channel function and providing a detailed up-to-date review of the phsyiological and pharmacological aspects of individual ion channel sub-families, this book constitutes both an excellent introduction to the field for non-specialists, as well as a highly valuable reference text for experienced researchers already working in the ion channel area.
Download or read book Ion Channel Diseases written by and published by Academic Press. This book was released on 2011-09-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion channel dysfunction in humans leads to impairment of the excitable processes necessary for the normal function of several tissues, such as muscle and brain. It follows that an increasing number of human diseases have been associated with malfunctioning ion channels, many of which have a genetic component. This volume of Advances in Genetics presents a broad and comprehensive overview of the inherited channelopathies in humans, including clinical, genetic and molecular aspects of these conditions. Keeping true to the scope of the serial, novel genomic and modeling research approaches and a review of potential therapeutic approaches for each of these conditions are also incorporated.
Book Synopsis Neuroscience in the 21st Century by : Donald W. Pfaff
Download or read book Neuroscience in the 21st Century written by Donald W. Pfaff and published by Springer. This book was released on 2016-10-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edited and authored by a wealth of international experts in neuroscience and related disciplines, this key new resource aims to offer medical students and graduate researchers around the world a comprehensive introduction and overview of modern neuroscience. Neuroscience research is certain to prove a vital element in combating mental illness in its various incarnations, a strategic battleground in the future of medicine, as the prevalence of mental disorders is becoming better understood each year. Hundreds of millions of people worldwide are affected by mental, behavioral, neurological and substance use disorders. The World Health Organization estimated in 2002 that 154 million people globally suffer from depression and 25 million people from schizophrenia; 91 million people are affected by alcohol use disorders and 15 million by drug use disorders. A more recent WHO report shows that 50 million people suffer from epilepsy and 24 million from Alzheimer’s and other dementias. Because neuroscience takes the etiology of disease—the complex interplay between biological, psychological, and sociocultural factors—as its object of inquiry, it is increasingly valuable in understanding an array of medical conditions. A recent report by the United States’ Surgeon General cites several such diseases: schizophrenia, bipolar disorder, early-onset depression, autism, attention deficit/ hyperactivity disorder, anorexia nervosa, and panic disorder, among many others. Not only is this volume a boon to those wishing to understand the future of neuroscience, it also aims to encourage the initiation of neuroscience programs in developing countries, featuring as it does an appendix full of advice on how to develop such programs. With broad coverage of both basic science and clinical issues, comprising around 150 chapters from a diversity of international authors and including complementary video components, Neuroscience in the 21st Century in its second edition serves as a comprehensive resource to students and researchers alike.
Book Synopsis Ion Channel Localization by : Anatoli Lopatin
Download or read book Ion Channel Localization written by Anatoli Lopatin and published by Springer Science & Business Media. This book was released on 2008-02-06 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the pioneering discoveries of Hodgkin, Huxley, and Katz, it has been clear that specific ion conductance pathways underlie electrical act- ity. Over the ensuing 50 years, there has been ever increasing, and occasi- ally explosive, changes in the scope of efforts to understand ion channel behavior. The introduction of patch clamp technology by Erwin Neher and Bert Sakmann about 20 years ago led to the realization of the great variety of novel ion channel species, and the subsequent revolution in cl- ing has revealed an even greater diversity of the underlying molecular entities. Today, advances in the study of ion channel structure and function c- tinue at a high pace, from angstrom resolution imaging of crystallized ch- nels to their genetic manipulations in animals. In this regard, the field is a balanced one that inquires not only what ion channel entities are there, or how they operate, but also where are these molecular electronic switches? However, this balance is not particularly well presented to the general sci- tific audience or to specialists in the field. There are plenty of wonderful and useful books and monographs, as well as conferences and meetings on v- tually every aspect of ion channel structure and function. However, we are unaware that the channel localization theme has been considered in a u- fied forum.

Book Synopsis Ion Channels and Disease by : Frances M. Ashcroft
Download or read book Ion Channels and Disease written by Frances M. Ashcroft and published by Academic Press. This book was released on 1999-10-20 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion channels are membrane proteins that act as gated pathways for the movement of ions across cell membranes. They play essential roles in the physiology of all cells. In recent years, an ever-increasing number of human and animal diseases have been found to result from defects in ion channel function. Most of these diseases arise from mutations in the genes encoding ion channel proteins, and they are now referred to as the channelopathies. Ion Channels and Disease provides an informative and up-to-date account of our present understanding of ion channels and the molecular basis of ion channel diseases. It includes a basic introduction to the relevant aspects of molecular biology and biophysics and a brief description of the principal methods used to study channelopathies. For each channel, the relationship between its molecular structure and its functional properties is discussed and ways in which genetic mutations produce the disease phenotype are considered. This book is intended for research workers and clinicians, as well as graduates and advanced undergraduates. The text is clear and lively and assumes little knowledge, yet it takes the reader to frontiers of what is currently known about this most exciting and medically important area of physiology. Introduces the relevant aspects of molecular biology and biophysics Describes the principal methods used to study channelopathies Considers single classes of ion channels with summaries of the physiological role, subunit composition, molecular structure and chromosomal location, plus the relationship between channel structure and function Looks at those diseases associated with defective channel structures and regulation, including mutations affecting channel function and to what extent this change in channel function can account for the clinical phenotype
