Download or read book NaCl Transport in Epithelia written by R. Greger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the pioneering studies by Ussing and co-workers, studies of epithelial Nael transport have come a long way. The first phase of the phenomenological description of the cell as a black box has been follow ed by studies of cellular mechanisms, the interplay of the different trans port components, and the mechanisms of regulation. A broad spectrum of methods has been applied to many epithelia in a variety of species. For the individual epithelia transport schemes have been proposed, and, at this point I think it is appropriate to take a pause and search for elements common to several epithelia. This aspect triggered the publica tion of this book, and in fact the various chapters emphasize that the funetional eomponents, expressed in the various epithelia, are not in finite in number, but they occur in epithelia which are separated in evolu tion by several hundred million years. The authors come both from the field of veterinary and human physiology as weIl as from biology. In my opinion, the close contacts and eollaborations between physiologists and biologists have been essential for the progress in this field. I wish to thank all authors for their con tributions, and I hope that the reader will appreciate this collection of up to date reviews on epithelia in nonvertebrates and vertebrates.
Book Synopsis Computational Modelling of Fluid and Ion Transport in the Epithelial Cell by : Shelley Fong
Download or read book Computational Modelling of Fluid and Ion Transport in the Epithelial Cell written by Shelley Fong and published by . This book was released on 2018 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Secretory epithelia line organs in the human body, and exquisitely control fluid and solute transport between interior and external cavities. Dysregulation results in abnormal fluid secretion rates, leading to disease. We developed a mathematical model of a generic epithelial cell to simulate these transport processes. This system can be adapted to model transport across different epithelia - here, it was used to obtain insight into normal and pathological conditions in salivary and alveolar epithelia. Regarding saliva secretion, clinical trials have shown that irradiated parotid glands with low salivary output saw a partial restoration following transfection of aquaporin, contradicting the traditional view which predicted that fluid be absorbed out of saliva instead. To help explain this, several units of the single cell were combined into a model of the parotid duct. Model results were most aligned to experimental data when a subgroup of water permeable cells were introduced to the proximal duct, and received the majority of the transfected aquaporin. Coupled with alterations in channel expression, these changes led to increased secretion, and predicted higher bicarbonate content in the final saliva. We also fitted the generic model with characteristics of an alveolar epithelial cell, and compared against experimental observations. At baseline, it was found that the cell was absorptive, where transcellular sodium flux dominated; chloride flux was 200 times smaller. It was found that blocking the cystic fibrosis transmembrane regulator had limited impact at baseline, but was the key to the transport of fluid in both normal and edematous states. Nucleotide signalling was also incorporated into the alveolar cell model, where mechanical forces increased the rate of nucleotide secretion. We found that periodic stretch increased apical liquid volume, which led to flooding at prolonged straining beyond the range of tidal breathing. Desensitisation of purinoceptors helped prevent flooding if there were high adenosine triphosphate levels. Functional apical chloride transport was necessary for fluid secretion into the lumen. Our generic model shows that regulation of fluid transport is complex. By reproducing trends that were observed experimentally, the model could be used to highlight pathways to be exploited in the treatment of diseases induced by defective transport.
Book Synopsis Epithelial Secretion of Water and Electrolytes by : John A. Young
Download or read book Epithelial Secretion of Water and Electrolytes written by John A. Young and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume aims to give a comprehensive overview of the cellular mechanisms underlying the process of secretion in vertebrate, particularly mammalian, exocrine glands. The subject matter is divided into two sections. The first section deals with general aspects of secretion, including chapters on the roles of ion channels in secretion. Signal transduction is also covered, and several chapters deal with recently developed investigative techniques that offer promise as tools for the further investigation of exocrine secretory processes. The second section deals with secretion in a selection of exocrine organs: salivary glands, lacrimal glands, the pancreas, gastric mucosa, liver, epididymis, and vertebrate salt glands. A final chapter deals with cystic fibrosis, the common, fatal, inherited disease, which affects exocrine glands particularly severely.
Book Synopsis Water Relations in Membrane Transport in Plants and Animals by : Arthur M. Jungreis
Download or read book Water Relations in Membrane Transport in Plants and Animals written by Arthur M. Jungreis and published by Elsevier. This book was released on 2013-10-22 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Relations in Membrane Transport in Plants and Animals contains the presentations in a symposium dealing with Water Relations in Membranes in Plants and Animals, during the 27th Annual Fall Meeting of the American Physiological Society held at The University of Pennsylvania, 17-19 August 1976. The purpose of the symposium was to explore the common modes of water regulation in plants and animals. In these proceedings, the mechanisms employed to restrict water flow across plant and metazoan animal cells are described. Putative differences in mechanisms of water regulation retained by plant versus animal cells become inconsequential in the light of the numerous similarities: dependence upon bioelectric potentials maintained across cell membranes, energy dependence of uphill water movement, and solute coupling during water transport. The presentations can be organized into four. The first takes up specific mechanisms of water transport in plants. The second and third parts deal with specific mechanisms in invertebrates and vertebrates, respectively. The fourth part covers generalized mechanisms common to plants and animals.

Book Synopsis Transporting Epithelia by : Michael Berridge
Download or read book Transporting Epithelia written by Michael Berridge and published by Elsevier. This book was released on 2012-12-02 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transporting Epithelia summarizes the progress that has been made in understanding a wide range of epithelial transport systems. This book discusses the epithelia involved in osmotic and ionic regulation from protonephridia to the mammalian kidney. It also explains the digestive and absorptive epithelia, as well as the epithelia that produce special secretions, such as milk, endolymph, aqueous humor, cerebrospinal fluid, sweat, and tears. Furthermore, this book describes the role of the epithelium in the physiology of the animal and the structure of the epithelium. Then, the structure of the epithelium is correlated with its physiological properties. This book will be valuable both for teaching and as a reference for research workers interested in comparative aspects of transport phenomena.

Available in PDF, EPUB and Kindle. Book excerpt: Epithelial cells probably constitute the most diverse group of cells found in the body. In addition to serving as interfaces between external and internal environments, their functions include ion and fluid secretion and reabsorp tion, protein exocytosis, hormone secretion, recognition, surface protection and the control of ciliary movement. By their very exposure on the surfaces of the body, epithelial cells are subjected to wide-ranging assault, by micro organisms and by chemical and physical forces. They are the targets for abrasion, infection and malignant transformation. Some epithelial cells show altered behaviour in inherited syndromes, such as cystic fibrosis, characterized by serious pancreatic and pulmonary disease. In view of the importance of epithelia and the fact that their function can be altered by environmental and inherited factors, they are the subject of intensive research, particularly so in the case of cancer where most tumours are of epithelial origin. The use of animal tissues in epithelial research continues to provide important advances and this, coupled with the need to focus more on human tissues, has prompted a greater research emphasis on accessible human epithelia and on the establishment of cell cultures from animal and human sources. For primary cell cultures and cell lines to be of value, they need to express properties appropriate to their progenitors and relevant to the study in progress.
Book Synopsis Intestinal Water and Electrolyte Transport in Health and Disease by : Mrinalin Rao
Download or read book Intestinal Water and Electrolyte Transport in Health and Disease written by Mrinalin Rao and published by Biota Publishing. This book was released on 2012-01-12 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unique architecture and physiology of the mammalian intestine, together with a tightly coordinated regulatory system, allows for the handling and absorption of as much as 9 L of fluid a day with 98% or greater efficiency. Advances in the past 40 years have made inroads into revealing the intricacies and interplay of numerous ion transporters and their modulators that are responsible for intestinal electrolyte and water transport. Studies of two devastating diseases, the virulent infectious disease cholera and the autosomal recessive disease cystic fibrosis, were largely responsible for this information explosion. These advances have been critical in the development of new therapeutic strategies to combat life-threatening diseases of varying etiologies ranging from enteric infections to cystic fibrosis and inflammatory bowel diseases. Yet, the story is far from complete, and progress needs to continue on translating information gained from reductionistic cell and tissue culture models, in vivo models, and ultimately human studies and on improving therapeutic approaches. This book reviews the current status of our knowledge of fluid transport across the intestine, including the complexities of transcellular and paracellular ion transport down the length of the intestine and how aberrations of normal physiological processes lead to disease.

Download or read book Epithelial Transport Physiology written by George A. Gerencser and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological cell membranes regulate the transfer of matter and information between the intracellular and extracellular compartments as basic survival and maintenance functions for an organism. This volume contains a series of reviews that are c- cerned with how epithelial plasma membranes regulate the transport of solutes between the intracellular and extracellular compartments of a cell. This book is also an attempt to analyze the molecular basis for the movement of various solutes across an epithelial cell membrane. This volume is devoted to a diversity of epithelial transport mechanisms in rep- sentative cell membranes of a variety of living things. The ?rst section of the book (Chapters 1–6) focuses on mechanisms of solute transport in epithelia of inver- brates. The last section which comprises ten chapters (Chapters 7–16) deals with solute transporters in epithelial cell membranes of vertebrates. It is hoped that with this particular ordering the reader can glean a telescopic view of the evolutionary history of the various epithelial solute transporters.
