Download or read book Blood Brain Barrier written by Sukriti Nag and published by Springer Science & Business Media. This book was released on 2008-02-01 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blood–brain barrier (BBB) breakdown leading to cerebral edema occurs in many brain diseases—such as trauma, stroke, inflammation, infection, and tumors—and is an important factor in the mortality arising from these con- tions. Despite the importance of the BBB in the pathogenesis of these diseases, the molecular mechanisms occurring at the BBB are not completely und- stood. In the last decade a number of molecules have been identified not only in endothelial cells, but also in astrocytes, pericytes, and the perivascular cells that interact with endothelium to maintain cerebral homeostasis. However, the precise cellular interactions at a molecular level in steady states and d- eases have still to be determined. The introduction of new research techniques during the last decade or so provide an opportunity to study the molecular mec- nisms occurring at the BBB in diseases. The Blood–Brain Barrier: Biology and Research Protocols provides the reader with details of selected morphologic, permeability, transport, in vitro, and molecular techniques for BBB studies, all written by experts in the field. Each part is preceded by a review that emphasizes the advantages and pitfalls of particular techniques, as well as offering much relevant current information. The techniques provided will be helpful to both beginners in BBB research and those more experienced investigators who wish to add a specific technique to those already available in their laboratories.

Download or read book GPI Membrane Anchors written by M Almeida and published by Academic Press. This book was released on 2012-12-02 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: GPI Membrane Anchors reviews major advances in our understanding of glycosylphosphatidylinositol (GPI) membrane anchors. The book examines the GPI structure and its originality as an anchoring device, its ubiquitous distribution, the main steps of its biosynthetic pathway, and the elegant means by which a protein signals for GPI attachment. It also presents evidence for the uniqueness of GPI as a tag in intracellular traffic and as a mediator of transmembrane signaling. This volume is organized into 20 chapters and begins with a discussion of the structural requirements of a nascent protein for processing to a PI-G anchored form, with emphasis on experiments on intact cells and cell-free systems. It then turns to the mechanisms underlying signal transduction by GPI-anchored membrane proteins, the LY-6 superfamily of GPI-anchored molecules, and glycosylated-phosphatidylinositols as virulence factors in Leishmania. The reader is also introduced to the molecular biology of GPI-anchored border hydrolases, the role of GPIs and their inositolglycan derivatives in the mediation of insulin and growth factor function, and biosynthesis and cellular localization of GPI-modified glycoproteins in Saccharomyces cerevisiae. An account of electrospray mass spectrometry of a C-terminal peptide purified from the scrapie isoform of the scrapie prion protein is also given. The book concludes with a chapter on GPI-anchored recognition molecules that function in axonal fasciculation, growth, and guidance in the nervous system. This book is a valuable resource for students and researchers in the fields of cell biology and biochemistry.

Download or read book Membrane Permeability 100 Years Since Ernest Overton written by and published by Academic Press. This book was released on 1999-05-21 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane permeability is fundamental to all cell biology and subcellular biology. The cell exists as a closed unit. Import and export depend upon a number of sophisticated mechanisms, such as active transport, endocytosis, exocytosis, and passive diffusion. These systems are critical for the normal housekeeping physiological functions. However, access to the cell is also taken advantage of by toxic microbes (such as cholera or ptomaine) and when designing drugs. Ernest Overton, one of the pioneers in lipid membrane research, put forward the first comprehensive theory of lipid membrane structure. His most quoted paper on the osmotic properties of cells laid the foundation for the modern concepts of membrane function, most notably important in anesthesia. This book is designed to celebrate the centennial anniversary (in the first chapter) of Overton's work. Subsequent chapters present readers with up-to-date concepts of membrane structure and function and the challenge they pose for new explorations. - Provides an historical perspective of Overton's contributions to the theory of narcosis - Presents an overview of each permeability mechanism, including active transport, endocytosis, exocytosis, and passive diffusion

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.

Download or read book The Tight Junction and Its Proteins More Than Just a Barrier written by Michael Fromm and published by MDPI. This book was released on 2020-11-20 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: For a long time, the tight junction (TJ) was known to form and regulate the paracellular barrier between epithelia and endothelial cell sheets. Starting shortly after the discovery of the proteins forming the TJ—mainly the two families of claudins and TAMPs—several other functions have been discovered, a striking one being the surprising finding that some claudins form paracellular channels for small ions and/or water. This Special Issue includes 43 articles covering numerous dedicated topics including pathogens affecting the TJ barrier, TJ regulation via immune cells, the TJ as a therapeutic target, TJ and cell polarity, function and regulation by proteins of the tricellular TJ, TJ as a regulator of cellular processes, organ- and tissue-specific functions, TJ as sensors and reacting to environmental conditions, and last but not least, TJ proteins and cancer.

Available in PDF, EPUB and Kindle. Book excerpt: The explosion of the field of genetics over the last decade, with the new technologies that have stimulated research, suggests that a new sort of reference work is needed to keep pace with such a fast-moving and interdisciplinary field. Brenner's Encyclopedia of Genetics, Second Edition, Seven Volume Set, builds on the foundation of the first edition by addressing many of the key subfields of genetics that were just in their infancy when the first edition was published. The currency and accessibility of this foundational content will be unrivalled, making this work useful for scientists and non-scientists alike. Featuring relatively short entries on genetics topics written by experts in that topic, Brenner's Encyclopedia of Genetics, Second Edition, Seven Volume Set provides an effective way to quickly learn about any aspect of genetics, from Abortive Transduction to Zygotes. Adding to its utility, the work provides short entries that briefly define key terms, and a guide to additional reading and relevant websites for further study. Many of the entries include figures to explain difficult concepts. Key terms in related areas such as biochemistry, cell, and molecular biology are also included, and there are entries that describe historical figures in genetics, providing insights into their careers and discoveries. This 7-volume set represents a 25% expansion from the first edition, with over 1600 articles encompassing this burgeoning field Thoroughly up-to-date, with many new topics and subfields covered that were in their infancy or not inexistence at the time of the first edition. Timely coverage of emergent areas such as epigenetics, personalized genomic medicine, pharmacogenetics, and genetic enhancement technologies Interdisciplinary and global in its outlook, as befits the field of genetics Brief articles, written by experts in the field, which not only discuss, define, and explain key elements of the field, but also provide definition of key terms, suggestions for further reading, and biographical sketches of the key people in the history of genetics

Download or read book Cell Membrane Transport written by Arnost Kotyk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: TO THE SECOND EDITION When preparing the manuscript for the original edition of this book we were only partly aware of the pace at which the field of membrane transport was developing and at which new ideas as well as new techniques would be applied to it. The fact is that some of the chapters are now outdated (e. g. , the one on the molecular aspects of transport) and many others require revision in the light of new information that has appeared in the past five years. However, it is also true that we overemphasized in the first edition certain points that now appear less important and underestimated the impact of certain others that have since assumed a position among the most forcefully discussed topics of membrane research. In making amends, it was thus thought useful to include the discussion of these latter problems both in the theoretical and in the comparative sections and, on the other hand, to omit some of the less topical subjects. There was a different reason for rewriting the section on kidney and for dropping the section on mito chondria. The help of an expert nephrologist was enlisted for improving chapter 24, while it was decided that mitochondria represent a special field both conceptually (being only subcellular particles) and methodologically (more indirect estimation techniques being involved than with whole cells or tissues) and that more adequate information can be found in treatises specializing in work with mitochondria.

Download or read book Regulation of Endothelial Barrier Function written by Sarah Y. Yuan and published by Biota Publishing. This book was released on 2011-02-01 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vascular endothelium lining the inner surface of blood vessels serves as the first interface for circulating blood components to interact with cells of the vascular wall and surrounding extravascular tissues. In addition to regulating blood delivery and perfusion, a major function of vascular endothelia, especially those in exchange microvessels (capillaries and postcapillary venules), is to provide a semipermeable barrier that controls blood–tissue exchange of fluids, nutrients, and metabolic wastes while preventing pathogens or harmful materials in the circulation from entering into tissues. During host defense against infection or tissue injury, endothelial barrier dysfunction occurs as a consequence as well as cause of inflammatory responses. Plasma leakage disturbs fluid homeostasis and impairs tissue oxygenation, a pathophysiological process contributing to multiple organ dysfunction associated with trauma, infection, metabolic disorder, and other forms of disease. In this book, we provide an updated overview of microvascular endothelial barrier structure and function in health and disease. The discussion is initiated with the basic physiological principles of fluid and solute transport across microvascular endothelium, followed by detailed information on endothelial cell–cell and cell–matrix interactions and the experimental techniques that are employed to measure endothelial permeability. Further discussion focuses on the signaling and molecular mechanisms of endothelial barrier responses to various stimulations or drugs, as well as their relevance to several common clinical conditions. Taken together, this book provides a comprehensive analysis of microvascular endothelial cell and molecular pathophysiology. Such information will assist scientists and clinicians in advanced basic and clinical research for improved health care.
