This book sheds new light on the physiology, molecular biology and pathophysiology of epithelial ion channels and transporters. It combines the basic cellular models and functions by means of a compelling clinical perspective, addressing aspects from the laboratory bench to the bedside. The individual chapters, written by leading scientists and clinicians, explore specific ion channels and transporters located in the epithelial tissues of the kidney, intestine, pancreas and respiratory tract, all of which play a crucial part in maintaining homeostasis. Further topics include the fundamentals of epithelial transport; mathematical modeling of ion transport; cell volume regulation; membrane protein folding and trafficking; transepithelial transport functions; and lastly, a discussion of transport proteins as potential pharmacological targets with a focus on the pharmacology of potassium channels.

Since the first TRP ion channel was discovered in Drosophila melanogaster in 1989, the progress made in this area of signaling research has yielded findings that offer the potential to dramatically impact human health and wellness. Involved in gateway activity for all five of our senses, TRP channels have been shown to respond to a wide range of st

Lung Epithelial Biology in the Pathogenesis of Pulmonary Disease provides a one-stop resource capturing developments in lung epithelial biology related to basic physiology, pathophysiology, and links to human disease.

Medical and graduate students, postdoctoral and clinical fellows, as well as clinicians interested in the mechanistic basis for lung disease will benefit from the books examination of principles of lung epithelium functions in physiological condition. - Provides a single source of information on lung epithelial junctions and transporters - Discusses of the role of the epithelium in lung homeostasis and disease - Includes capsule summaries of main conclusions as well as highlights of future directions in the field - Covers the mechanistic basis for lung disease for a range of audiences

This book discusses unique ion channels and transporters that are located within epithelial tissues of various organs including the kidney, intestine, pancreas and respiratory tract. The authors will show, that each of these channels and transporters play crucial roles in transepithelial ion and fluid transport across epithelia and their responsibility in maintaining homeostasis. The reader gains an understanding of the fundamentals of epithelial ion transport, in terms of function, modelling, regulation, trafficking, structure and pharmacology. This is the third of three volumes highlighting the importance of epithelial ion channels and transporters in basic physiology and pathophysiology of human diseases. The focus of this volume lies with different ion channel and transporter families. Additionally, this volume benefits from pharmaceutical contributors and their insights into recent pre-clinical drug discovery efforts and results from clinical trials. Overall, these chapters offer a more thorough coverage of individual epithelial ion channels and transporters from the 1st Edition, along with eleven new chapters. That makes Volume 3 an insightful contribution for physiology students, scientists and clinicians.

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.

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

This book discusses unique ion channels and transporters that are located within epithelial tissues of various organs including the kidney, intestine, pancreas and respiratory tract. As the authors show, these channels and transporters play crucial roles in transepithelial ion and fluid transport across epithelia and their contribution to maintaining homeostasis. Readers will be introduced to the fundamentals of ion transport in terms of function, modelling, regulation, structure and pharmacology. This is the first of three volumes highlighting the importance of epithelial ion channels and transporters in basic physiology and pathophysiology of human diseases. This volume focuses on basic fundamentals of epithelial transport physiology. There is a range of chapters dedicated to specific aspects of epithelial ion transport and cell function. Accordingly, the authors discuss techniques used to determine epithelial function, principles of epithelia transport, polarization of epithelial cells, mathematical modelling of epithelial ion transport, protein folding of ion channels, degradation epithelial ion channels, fundamentals of epithelial sodium, potassium and chloride transport, fundamentals of bicarbonate secretion, volume regulation, and microRNA regulation of epithelial channels and transporters. Given its scope, Volume 1 offers a valuable resource for physiology students, scientists and clinicians alike.
