Book Synopsis Virus Receptors by : K. Longberg-Holm
Download or read book Virus Receptors written by K. Longberg-Holm and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is hardly necessary to define the concept of receptors to readers of this series, but it should be borne in mind that in several instances receptors are undefined entities, whose molecular details remain to be established. On the other hand the ligand, which recognizes the receptors, has been identified and characterized in most cases. The current interest in the structure and function of biological membranes gives great expectations that we may understand in the near future the details of ligand-receptor interaction. This interaction involves two defined steps: the first, usually referred to as recognition, is followed by the second step, transduction, in which the ligand-receptor interaction is translated by the cell into a biochemical action. The present two volumes which cover prokaryotic and eukaryotic virus receptors, have been published together in order to illustrate the specificity of virus receptor recognition which appears to be a guiding principle for both bacteria and higher cells. The identification and characterization of the receptors for phages of gram-negative bacteria has to a large extent relied on the genetic tech niques available for these organisms. In a similar way the availability of genetic systems has also clarified the interrelationship between animal retrovirus receptors even if the molecular structure remains to be determined. The paucity of defined genetic systems may therefore explain part of our ignorance concerning the mole cular details of virus receptors on human cells and possibly also on gram-positive bacteria.

Book Synopsis The Molecular Biology of Poliovirus by : F. Koch
Download or read book The Molecular Biology of Poliovirus written by F. Koch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: Years ago when we were asked to write a book on the present-day knowledge of the molecular biology of poliovirus, we did not expect that such an apparently simple task could involve so much time and effort. Our writing was hampered by the fact that both of us are full time "workers", so that this monograph is mainly a spare time expedience. The main attention of this book focuses on a detailed review of the molecular biology of poliovirus and especially on the advances of the last decade; medical and environmental aspects are only briefly mentioned. Observations from older studies are considered in view of more recent information. Some of the older ob servations provided fundamental insights and paved the way for present day research; too often such data has been neglected or independently rediscovered. Today, poliovirus research has again attracted considerable interest. High points gained within the last few years were the elucidation of the complete nucleotide sequences of the RNAs of the three poliovinls serotypes and the corresponding vaccine strains, the demonstration of genome evolution during transmission of poliovirus in an epidemic, further characterization of the antigenic sites on the virus particle and of the antigenic drift, characterization of alternate conforma tional states of the virion capsid, the development of monoclonal antibodies against some of the virus proteins, observations on the role of the plasma membrane, cytoskeleton, and cytoplasmic membranes as mediators in the virus induced redirection of the synthetic machinery of the host cell, and characteriza
Book Synopsis Neurotransmitter Receptors by : Sam J. Enna
Download or read book Neurotransmitter Receptors written by Sam J. Enna and published by Springer Science & Business Media. This book was released on 2013-12-12 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery that neuronal transmission can be chemically mediated, a large number of compounds have been found in the mammalian central nervous system which appear to function as neurotransmitter agents. Recently, electro physiological and biochemical methods have been developed which have enabled neuroscientists to classify better the myriad of neurotransmitter receptor sites in brain and to study their properties in finer detail. As a result of these investigations, a significant number of new discoveries have been made about the mechanisms involved in neurotransmitter receptor interactions, the role neurotransmitters play in the actions of pharmacological agents and in the pathogenesis of various neuropsychiatric disorders. The present two volume text was compiled to summarize the information relating to the physiological, biochemical, pharmacological and functional characteristics of neurotransmitter receptor sites. While emphasis is placed on neurotransmitter receptors in the mammalian central nervous system, the characteristics of these receptors in other species, both vertebrate and invertebrate, are also discussed where appropriate. While these books cover the major classes of putative neurotransmitters - amino acids, peptides and biogenic amines - and are therefore broad in scope, each is discussed in a concise fashion to highlight the major points of historical and contemporary interest. In addition to outlining data, each chapter addresses current theories relating to the various aspects of receptor properties and function in an attempt to reveal the directions of future research and as a stimulus for other workers in the field.
Book Synopsis Concepts in Viral Pathogenesis by : A. L. Notkins
Download or read book Concepts in Viral Pathogenesis written by A. L. Notkins and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current proliferation of scientific information makes it difficult for even the most diligent reader to keep up with the latest developments in his/her own field, let alone other areas of interest. Review articles are one solution, but they too have become so voluminous and detailed that they often defeat the purpose for which they were intended. We have attempted to ease this problem by using a different format. In this volume on Concepts in Viral Pathogenesis, we have assembled a series of mini-reviews/editorials, 1,000 to 2,000 words in length. Each is a pithy distil lation of the state-of-the-art with emphasis on current thinking and unifying concepts rather than a compendium of the literature. The 53 articles, all written by active workers in their respective fields, are organized systemati cally so that the book will provide busy investigators, teachers and students of up-to-date information in a very brief and easily read a conceptual core able form. In addition, the authors have attempted to identify unresolved problems and point to future directions.
Book Synopsis Membrane Receptors by : P. Cuatrecasas
Download or read book Membrane Receptors written by P. Cuatrecasas and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardly a decade ago, membrane receptors were an attractive but largely unproven concept. Since that time enormous progress has been made, and we are now able to consider receptors much more concretely. Their existence has been established, their binding properties have been determined, and in some cases, they have been highly purified and their physical-chemical properties studied. It is now even possible to visualize microscopically some receptors. This progress has resulted largely from the development of highly powerful methods. These methods are the subject of this volume. Although considerably diverse, different receptors share certain common pro perties, and common problems are encountered in their study. Consequently, a small number of techniques are particularly useful in studying different types of receptors. Thus, it makes sense to speak about membrane receptor methodology. A very apparent problem in the study of membrane receptors is their presence in exceedingly small quantities and in a highly impure state. Therefore, very sensitive and specific techniques are required for their detection, characterization and purification. Such sensitivity and specificity is provided by the ability of receptors to bind certain ligands with very high affmity, and it is not surprising that most of the methods described in this volume depend upon this high affinity binding. The antigen-antibody interaction is of comparable sensitivity and speci ficity. Recently, a number of anti-receptor antibodies have been produced or found to occur spontaneously in auto-immune diseases. Undoubtedly, more will be produced in the future.
Book Synopsis Viral Insecticides for Biological Control by : Karl Maramorosch
Download or read book Viral Insecticides for Biological Control written by Karl Maramorosch and published by Elsevier. This book was released on 2012-12-02 with total page 822 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viral Insecticides for Biological Control focuses on the basic as well as applied aspects of viral insecticides, which have the potential to significantly reduce the current reliance on chemical pesticide technology. This book serves as a guide for the development of means to identify hazardous problems and prevent them. Organized into six parts with a total of 23 chapters, this book describes the taxonomy, nomenclature, identification, physical, biological, as well as chemical characteristics, replication, and pathology of insect viruses. This reference material also explores the dispersal, stability, and utilization of insect viruses as biological control agents. The factors and considerations that must be taken into account when a viral insecticide is sought as a large-scale commercial alternative to other more traditional methods of pest control are also addressed. Because this reference material collates information in this field of interest, it will benefit a wide audience of readers, including researchers, students, and those working directly in crop protection.

Book Synopsis Purinergic Receptors by : G. Burnstock
Download or read book Purinergic Receptors written by G. Burnstock and published by Springer Science & Business Media. This book was released on 2013-03-07 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifty-odd years have elapsed since the first observation of the response of visceral smooth muscle to an adenine nucleotide was reported by Drury and Szent Gyorgi (1929). It is now known that purinergic receptors mediating responses to adenosine and the adenine nucleotides (AMP, ADP and ATP) are present in all types of visceral smooth muscle. Adenine itself and other endogenous purine derivatives appear to have no direct effects, or only minimal effects, on most visceral smooth muscles. Airway smooth muscle is an exception in this regard, and responds to purine bases and non-adenine nucleosides and nucleotides. Knowledge of the distribution of purinergic receptor sites on the plasma membrane of visceral musculature has grown particularly rapidly since Burnstock and his colleagues (1970) proposed that ATP, or a related adenine derivative, is the inhibitory transmitter released from non cholinergic non-adrenergic nerves present in the gut. Much evidence has been presented favoring the view that ATP is the inhibitory transmitter, and evidence to the contrary has also been put forward. The hypothesis remains controversial primarily because specific blockers of the postsynaptic purinergic site, with which the hypothesis might be tested, have not been found. Nevertheless, the numerous studies designed to investigate the purinergic nerve hypothesis have generated much information concerning the nature of the purinergic receptors in visceral smooth muscle.
Book Synopsis Receptor-Mediated Endocytosis by : P. Cuatrecasas
Download or read book Receptor-Mediated Endocytosis written by P. Cuatrecasas and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses exclusively on those endocytic processes that sequester proteins by a selective, receptor-mediated mechanism. In such an endocytic process, cell surface receptors specifically bind protein ligands and localize them to specialized invaginations of the plasma membrane. These regions are coated pits, so named because they are lined on the cytoplasmic face with an ordered array of the protein, clathrin. It is this 'coat' which provides their characteristic electron microscopic image. Subsequently, these regions pinch off to form coated vesicles which rapidly lose their 'coat' and then fuse with other organelles or the plasma membrane. The hallmarks of ,this process are the specific receptors, coated pits, coated vesicles and an ordered sequence of transit events leading to delivery to selected locations. Receptor recognition, specific disposition of the endocytosed ligand and the existence of recep tor-ligand complexes at highest density in coated pits define the process as selective and concentrative. This topic has received ever increasing attention during the past few years. The evolving mechanisms are especially exciting because they come at a time when the conventional views based on thermodynamic arguments suggest that proteins should not be able to cross into the cell. Receptor-mediated endocytosis, however, reconciles the view that biological membranes should be impervious to macromolecules with the evidence that certain mac romolecules do gain entrance into the cell. During the last few years this field has been stimulated by studies on the uptake and processing of low density lipoproteins (LDL) by cells.
Download or read book The Receptors written by P. Michael Conn and published by Academic Press. This book was released on 2014-05-10 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Receptors, Volume II deals with receptors for somatostatin, vitamin D, insulin, and animal viruses, as well as for the ?2-adrenergic and Ah systems. The significance of translational modifications of receptor ligands is discussed, along with the mechanisms of receptor-ligand interactions. The role of receptors in development and their regulation by tumors are also considered. Comprised of 12 chapters, this volume begins with a detailed account of the vitamin D receptor, paying particular attention to its biochemical and physical properties as well as its mechanism of action. The discussion then turns to experimental discrimination between alternative mechanistic models for the receptor-mediated stimulation of adenylate cyclase; the role of microaggregation in hormone-receptor-effector interactions; and the biology and biochemistry of the Ah receptor. Subsequent chapters explore the interactions of animal viruses with cell surface receptors; insulin receptors; determination of the size of neurotransmitter receptors by radiation inactivation-target size analysis; and protein glycosylation and receptor-ligand interactions. This book will be a valuable resource for students and practitioners in fields ranging from cell biology and biochemistry to physiology, endocrinology, and pharmacology.

Book Synopsis Coxsackieviruses by : Mauro Bendinelli
Download or read book Coxsackieviruses written by Mauro Bendinelli and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now just 40 years since coxsackieviruses were first isolated by Dalldorf and Sickles in the "eponymous" town of Coxsackie, New York. Yet the overall contribution of coxsackieviruses to clinically evident dis ease of humans is still largely an open problem. Following their discov ery, coxsackieviruses were under intense clinical and laboratory scrutiny for a long time. Because of their relationship to polioviruses, the under standing of their structure, biochemistry, biology, and epidemiology ad vanced rapidly as a result of the formidable efforts that eventually led to the defeat of poliomyelitis. The ability of these viruses to infect mice permitted dissection of their pathogenicity in an experimental host and elucidation of conditions that influence its expression. Coxsackieviruses have been progressively associated with an increasing array of widely diverse human diseases. However, only some of the suggested causal correlations have been substantiated with satisfactory certainty. For others, conclusive evidence has so far resisted investigation. Most impor tant, among the latter are chronic maladies, such as dilated car diomyopathy and juvenile diabetes, that demand consideration. In recent times, there has been a partial eclipse of the subject of coxsackieviruses in the medical literature. In addition to the difficulties encountered in pinpointing their pathogenic potential, possible reasons include the general decline of interest in enteroviruses, which ensued after the conquest of poliomyelitis, and the continuous appearance in the limelight of new, more esoteric, and therefore more "appealing" viruses.

Book excerpt: In calling this series Molecular Plant Virology, I had in mind aspects of plant virology of interest to biochemists, molecular geneticists, biophysicists, genetic engineers, or, collectively,molecular biologists. At the same time, the intention was to provide up-to-date reviews, by expert contributors, on current research topics in plant virology of interest and referential use to virologists and plant biologists. The selected topics are pitched mainly at a research level, but with sufficient introduction and cross-referencing to enable graduate students to enter this fascinating field and, hopefully, not get lost.
Book Synopsis Genetic Analysis of the Cell Surface by : P. Goodfellow
Download or read book Genetic Analysis of the Cell Surface written by P. Goodfellow and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cell surface is the barrier between the cell and its environment which regulates the flow of both simple and complex molecules into and out of the cell; it is also the organelle responsible for communication between the cell and its environment. Each cell expresses receptors for a wide variety of hormones, growth factors, growth substrates and other cells. In multicellular organisms communication between cells is required for controlling development, cellular differentiation, morphogenesis and, in a more general sense, integration of myriad cell types into a single organism. The series Receptors and Recognition has as its overall aim the dissection of the cell surface to correlate structure and function for this complex organelle. In most of the preceding volumes the approach has been biochemical or physiological. In this volume the mammalian cell surface is analysed by a genetic approach. Genetic analysis of the cell surface, especially when combined with immuno logical techniques, has a long history. In 1900 Landsteiner showed that serum from one individual could agglutinate the red cells of another. Besides the practical result of making blood transfusion safe, this was the first demon stration of a human genetic polymorphism and for the next 50 years the red blood cell surface provided most of the genetic markers used to study human populations.
