Download or read book Membrane Trafficking in Viral Replication written by Mark Marsh and published by Springer Science & Business Media. This book was released on 2005-10-25 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viruses are major pathogens in humans, and in the organisms with which we share this planet. The massive health and economic burden these agents impose has spurred a huge research effort to understand their most intimate details. One outcome of this effort has been the production, in many but certainly not all cases, of effective vaccines and therapies. - other consequence has been the realization that we can exploit viruses and put them to work on our behalf. Viruses are still seen to have the most - tential as vehicles for gene delivery and other therapeutic applications. However, their ability to exploit cellular functions to their own ends makes viruses not only highly effective pathogens but also exquisite experimental tools. Work with viruses underpins much of our current understanding of molecular cell biology and related fields. For membrane traffic in parti- lar, viruses have been crucial in providing insights into key cellular fu- tions and the molecular mechanisms underlying these events.

Download or read book Fusion of Biological Membranes and Related Problems written by Herwig J. Hilderson and published by Springer Science & Business Media. This book was released on 2005-11-19 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Membrane fusion and targeting processes are tightly regulated and coordinated. Dozens of proteins, originating from both the cytoplasm and membranes are involved. The discovery of homologous proteins from yeast to neurons validates a unified view. Although much is known about the interfering proteins, the events occurring when two lipid bilayers actually fuse are less clear. It should be remembered that lipid bilayers behave like soap-bubbles fusing when meeting each other. In this respect interfering proteins should be considered as preventing undesirable and unnecessary fusion and eventually directing the biological membrane fusion process (when, where, how, and overcoming the activation energy). In this latest volume in the renowned Subcellular Biochemistry series, some aspects of fusion of biological membranes as well as related problems are presented. Although not complete, there is a lot of recent information including on virus-induced membrane fusion. The contributors of the chapters are all among the researchers who performed many of the pioneering studies in the field.

Download or read book Viral Molecular Machines written by Michael G. Rossmann and published by Springer Science & Business Media. This book was released on 2012-02-02 with total page 685 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will contain a series of solicited chapters that concern with the molecular machines required by viruses to perform various essential functions of virus life cycle. The first three chapters (Introduction, Molecular Machines and Virus Architecture) introduce the reader to the best known molecular machines and to the structure of viruses. The remainder of the book will examine in detail various stages of the viral life cycle. Beginning with the viral entry into a host cell, the book takes the reader through replication of the genome, synthesis and assembly of viral structural components, genome packaging and maturation into an infectious virion. Each chapter will describe the components of the respective machine in molecular or atomic detail, genetic and biochemical analyses, and mechanism. Topics are carefully selected so that the reader is exposed to systems where there is a substantial infusion of new knowledge in recent years, which greatly elevated the fundamental mechanistic understanding of the respective molecular machine. The authors will be encouraged to simplify the detailed knowledge to basic concepts, include provocative new ideas, as well as design colorful graphics, thus making the cutting-edge information accessible to broad audience.
Download or read book Structure and Physics of Viruses written by Mauricio G. Mateu and published by Springer Science & Business Media. This book was released on 2013-06-04 with total page 734 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contemplates the structure, dynamics and physics of virus particles: From the moment they come into existence by self-assembly from viral components produced in the infected cell, through their extracellular stage, until they recognise and infect a new host cell and cease to exist by losing their physical integrity to start a new infectious cycle. (Bio)physical techniques used to study the structure of virus particles and components, and some applications of structure-based studies of viruses are also contemplated. This book is aimed first at M.Sc. students, Ph.D. students and postdoctoral researchers with a university degree in biology, chemistry, physics or related scientific disciplines who share an interest or are actually working on viruses. We have aimed also at providing an updated account of many important concepts, techniques, studies and applications in structural and physical virology for established scientists working on viruses, irrespective of their physical, chemical or biological background and their field of expertise. We have not attempted to provide a collection of for-experts-only reviews focused mainly on the latest research in specific topics; we have not generally assumed that the reader knows all of the jargon and all but the most recent and advanced results in each topic dealt with in this book. In short, we have attempted to write a book basic enough to be useful to M.Sc and Ph.D. students, as well as advanced and current enough to be useful to senior scientists with an interest in Structural and/or Physical Virology.
Download or read book Structural Mechanics of Class 1 Viral Membrane Fusion Proteins written by Mark Alexander Benhaim and published by . This book was released on 2020 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein-mediated membrane fusion is a highly regulated biological process essential for cellular and organismal functions and infection by enveloped viruses. During viral entry, the membrane fusion reaction is catalyzed by specialized protein machinery on the viral surface. These viral fusion proteins undergo a series of dramatic structural changes during membrane fusion where they engage, remodel, and ultimately fuse with the host membrane. The structural and dynamic nature of these conformational changes and their impact on the membranes have long-eluded characterization. Furthermore, the native pre-fusion structural and conformational dynamics of these fusion machines remains unclear as the conventional structural approaches employed by structural biologists are not well suited for studying these dynamic protein machines on the viral surface. The objective of this dissertation is to characterize the complete mechanism of Influenza virus hemagglutinin (HA) fusion activation and membrane fusion, and to profile and characterize the structural and conformational dynamics of the HIV-1 Env fusion glycoprotein on the viral surface. In chapter 2 I use continuous labeling HDX-MS to characterize the structural dynamics and conformational homogeneity of the HIV-1 Env fusion glycoprotein on the surface of two distinct engineered and authentic viral vaccine platforms. By HDX-MS we observed significant amounts of non-native Env present in one vaccine platform, whereas all Env present in the other resembled trimeric Env in the closed conformation. In chapter 3, I use pulse labeling HDX-MS to characterize the mechanism of HA fusion activation and HA mediated membrane fusion in situ using whole infectious virions. Our data reveal how concurrent reorganizations at the HA1 receptor binding domain interface and HA2 fusion subunit produce a dynamic fusion intermediate ensemble in full-length HA. In contrast, the soluble HA ectodomain transitions directly to the post-fusion state with no observable intermediate. These data provide unprecedented insight into the structural mechanics of HA which has served as the prototypical class 1 viral fusion protein and informed our understanding about how all class 1 viral fusion proteins function. In chapter 4 I present developments and improvements on the HDX-MS workflows that will enable more complete characterizations of HA's mechanism and the structural and conformational dynamics of other class 1 viral fusion proteins. Together these works have dramatically furthered our understanding of the structural mechanics of class 1 fusion proteins and lay the foundation for future studies on influenza virus and other enveloped viruses and their membrane fusion machinery.

Download or read book The Paramyxoviruses written by David W. Kingsbury and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: What justifies the size of this compendium of reviews on the paramyxoviruses? As intracellular parasites that reproduce with almost complete indifference to nuclear activities, paramyxoviruses have not been providing insights about genes that regulate cellular activities and development, topics that account for much of the excitement in modem biology. For contributions of virus research to those topics, we must look to the retroviruses, which have the propensity to steal developmentally important genes and subvert them to malignant pur poses, and to the nuclear DNA viruses, whose gene expression depends heavily upon cellular transcription machinery, making them exceptionally useful tools for identifying and characterizing components of that machinery. From this perspective, it may appear that purely lytic viruses like the paramyxoviruses are sitting on the sidelines of contemporary biology. But there is plenty of action on the sidelines. Paramyxoviruses remain unconquered, devastating agents of disease. Human deaths attributable to paramyxoviruses worldwide, especially in children, are numbered in the mil lions annually. There are many pathogenic paramyxoviruses and too few effec tive vaccines, and those vaccines (against measles and mumps) are affordable only by relatively affluent nations. Moreover, the paramyxoviruses are intrin sically interesting organisms, presenting the challenge of understanding the self-replication of RNA and many other challenges peculiar to the structures and functions of their proteins, not only as individual entities, but also as they act in concert during virus reproduction and interact with vital functions of the cells they infect and often (but not always) destroy.
Download or read book Cell Biology of Herpes Viruses written by Klaus Osterrieder and published by Springer. This book was released on 2017-05-20 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herpes viruses are widely distributed in nature, causing disease in organisms as diverse as bivalves and primates, including humans. Each virus appears to have established a long-standing relationship with its host, and the viruses have the ability to manipulate and control the metabolism of host cells, as well as innate and adaptive antiviral immune responses. Herpes viruses maintain themselves within hosts in a latent state resulting in virus persistence for years – usually for the life span of the hosts. Herpes viruses comprise a large number of pathogens with diverse cellular targets and biological consequences of infection. What they have in common is their structure and the fact that they establish a dormant (latent) infection in their hosts that usually persists for life. The reviews here will highlight the general principles of herpes virus infection, with equal attention to overall principle and important difference. Also, the cell type- and life-style dependent differences in the establishment and maintenance of virus persistence will be covered.
Download or read book The Togaviridae and Flaviviridae written by Sondra Schlesinger and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The publication of this volume of The Viruses entitled The Togaviridae and Flaviviridae comes at an appropriate time. The structure and rep lication strategies of these viruses are now known to be sufficiently di verse to warrant the removal of flaviviruses from the Togaviridae family and establish them as an independent family. Flaviviridae have a special place in the history of virology. The prototype virus-yellow fever virus was the first virus to be identified as the cause of a human disease. Some of the history of this discovery is described in Chapter 1 of this volume; in Chapter 10 the complete sequence of the RNA genome of the virus is presented. This sequence not only defines the primary structure of the viral proteins, it also clarifies the mechanism of translation of the fla vivirus genome. Knowledge of the sequence of the structural proteins of these viruses represents an important step in the potential goal of using purified flavivirus glycoproteins as vaccines. Many of the chapters in this volume focus on the structure and replication of the Togaviridae. These viruses have provided valuable models for studies in cell biology, partic ularly with regard to the cotranslational and posttranslational steps re quired for the synthesis and localization of membrane glycoproteins. Fur thermore, Togaviridae have been pivotal in our growing understanding of how enveloped viruses enter and exit from cells. The broad outlines of the structure and gene expression of Togavir idae and Flaviviridae are known, but important questions remain.
