Available in PDF, EPUB and Kindle. Book excerpt: This book gathers relatively recent and significant topics in the field of ion channel research. Ion channels form the molecular basis for membrane excitability in cells present in the cardiovascular and nervous systems. In many non-excitable cells, ion channels contribute to diverse physiological functions, including the secretion of signaling compounds like hormones and insulin, cell volume regulation, intracellular signaling, especially Ca2+ signaling, etc. Many human diseases have been attributed to abnormal channel functions and defective membrane expression of channel proteins. On the other hand, ion channels are excellent models for studying protein biophysics, especially the allosteric regulation of protein function by miscellaneous stimuli. Therefore, research on ion channels carries significant meaning for the understanding of basic protein biophysics and diverse physiological functions. Such vital information also assists in developing novel and effective treatments for related human diseases. This book provides graduates and scientists in both basic and clinical levels a comprehensive understanding of cutting-edge advances and a useful and stimulating platform for tackling their own questions about ion channels.

Download or read book Ion Channels written by David J. Aidley and published by Cambridge University Press. This book was released on 1996-08-13 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion channels are crucial components of living cells. Situated in the cell's membranes. they allow particular ions to pass from one side of the membrane to the other. In recent years the patch clamp technique has allowed the activity of individual channels to be measured, and recombinant DNA technology has led to fascinating detail on their structure. Together, these technical advances have produced a great flowering of knowledge and understanding about the subject, itself leading to further breakthroughs in science and medicine. Ion Channels provides an introduction to this scientific endeavour. It emphasises the molecular structure of channels as determined by gene cloning technology. This knowledge illuminates discussions of the permeability and selectivity of channels, their gating and modulation, their responses to drugs and toxins and the human diseases caused when they do not function properly.

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 Textbook of Ion Channels Volume III written by Jie Zheng and published by CRC Press. This book was released on 2023-06-28 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Textbook of Ion Channels is a set of three volumes that provides a wide-ranging reference source on ion channels for students, instructors and researchers. Ion channels are mem- brane proteins that control the electrical properties of neurons and cardiac cells; medi- ate the detection and response to sensory stimuli like light, sound, odor, and taste; and regulate the response to physical stimuli like temperature and pressure. In non-excitable tissues, ion channels are instrumental for the regulation of basic salt balance that is critical for homeostasis. Ion channels are located at the surface membrane of cells, giving them the unique ability to communicate with the environment, as well as the membrane of intracellular organelles, allowing them to regulate internal homeostasis. Ion channels are fundamentally important for human health and diseases, and are important targets for pharmaceuticals in mental illness, heart disease, anesthesia, pain and other clinical appli- cations. The modern methods used in their study are powerful and diverse, ranging from single ion-channel measurement techniques to models of ion channel diseases in animals, and human clinical trials for ion channel drugs. Volume III includes coverage of key ion channel regulators and their mechanisms, the role of ion channels working in concert in selected physiological systems, and examples of ion channel mutations and dysfunction in a selection of diseases. Chapters on ion channel regulation include splice variants, calcium–calmodulin regulation, regulation by G pro- teins, and lipids. A selection of ion channels in physiological systems includes ion chan- nels of the heart, ion channels in immune cells and their role in pancreatic beta cells and regulation of insulin secretion, and the role of channels in sperm and eggs. While disease mechanisms are integrated into the chapters of Volume II, Volume III offers special consid- eration of ion channels in epilepsy, cystic fibrosis and pain syndromes. All three volumes give the reader an introduction to fundamental concepts needed to understand the mechanism of ion channels, a guide to the technical aspects of ion channel research, offer a modern guide to the properties of major ion channel families, and includecoverage of key examples of regulatory, physiological, and disease roles for ion channels.

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
Download or read book Ion Channels written by T. Narahashi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wealth of information has been accumulated about the function of ion channels of excitable cells since the extensive and pioneering voltage clamp studies by Hodgkin, Huxley, and Katz 36 years ago. The study of ion chan nels has now reached a stage at which a quantum jump in progress is antici pated. There are many good reasons for this. Patch clamp techniques origi nally developed by Neher and Sakmann 12 years ago have made it possible to study the function of ion channels in a variety of cells. Membrane ionic currents can now be recorded practically from many types of cells using the whole-cell patch clamp technique. The opening and closing of individual ion channels can be analyzed using the single-channel patch clamp method. Techniques have also been developed to incorporate purified ion channels into lipid bilayers to reconstitute an "excitable membrane. " Advanced tech niques developed in molecular biology, genetics, and immunology, such as gene cloning and the use of monoclonal antibodies, are now being applied to the study of ion channels. A variety of drugs have now been found or are suspected to interact with ion channels to exert therapeutic effects. In addition to the classical exam ples, as represented by local anesthetics, many other drugs, including cal cium antagonists, psychoactive drugs, cardiac drugs, and anticonvulsants, shown to alter ion channel function. For certain pesticides such as have been pyrethroids and DDT, sodium channels are clearly the major target site.

Download or read book Ion Channel Reconstitution written by C. Miller and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now over 30 years since the idea of ion-conducting pores burst on the elec trophysiological scene, 15 years since these were generalIy realized to be mem brane-spanning proteins, and 10 years since the first observations of single ion channels from higher organisms were made. During the past 5 years, several integral membrane channel proteins have been purified in a functionalIy competent state: the nicotinic acetylcholine receptor, the Na + channel, mitochondrial "VDAC," and a variety of porins. The stage is thus set to attack ion channels in the same ways that biochemists have been attacking enzymes for decades: isolation folIowed by functional analysis in as simple a system as possible, with a view towards understanding the molecular mechanisms ofthe protein's behavior and how this is related to the underlying molecular structure. This is always a daunting task, alI the more so with ion channels because of our still primitive and scanty understanding of channel structures and because of the difficulty in iso lating functionally active channel proteins. In this volume, which can be considered a biochemically slanted companion to Sakmann and Neher's Single-Channel Recording, I have tried to present a view of the current landscape of ion-channel reconstitution. These chapters illustrate not only the different approaches and techniques of the major practitioners of ion channel reconstitution but, as importantly, the varied motivations for doing this kind of work.

Download or read book Nonselective Cation Channels written by Siemen and published by Birkhäuser. This book was released on 2013-03-08 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: It can be argued that nonselective cation channels were the first sort of ion channel to be described, though the word channel was not used at the time. Their existence was implied by Fatt and Katz in 1952, when they described the action of acetylcholine at the muscle endplate as producing "a large nonselective increase of ion permeability, i.e. a short circuit". Shortly afterwards, in 1956, Katz referred to "aqueous channels through which small ions can pass ... " (del Castillo and Katz, Prog. Biophysics and Biophys. Chern. 6, 121-170). Now, more than thirty years later, it has become clear that there are far more types of nonselective cation channels than anyone could have imagined a few years ago, and that they are found in a vast range of tissues. One has, of course, become quite accustomed to such diversity in, for example, GABA receptors, but this is not quite the same thing. A In the case of GABAA receptor we are talking about a fairly narrow range of structural diversity (resulting largely from differences in subunit composition) within a single type of channel with more-or-Iess well defined function. In the case of nonselective cation channels the function is often not known, and relatively few have been cloned. It seems certain though, that they encompass a wide range of quite different structural types.
