Available in PDF, EPUB and Kindle. Book excerpt: Viral Polymerases: Structures, Functions and Roles as Antiviral Drug Targets presents in-depth study information on the structure and functions of polymerases and their roles in the lifecycle of viruses, and as drug targets. Viral polymerases constitute a vital component in the lifecycle of many viruses, such as human immunodeficiency virus (HIV), hepatitis viruses, influenza virus, and several others. They are essentially required for the replication of viruses. Thus, the polymerases that can be found in viruses (called viral polymerases) represent favorable targets for the design and development of antiviral drugs. Provides comprehensive, state-of-the-art coverage on virus infections, the virus lifecycle, and mechanisms of polymerase inhibition Analyzes the structure-activity relationships of inhibitors of each viral polymerase Presents a consistent and comprehensive coverage of all aspects of viral polymerases, including structure, function and their role as antiviral drug targets

Download or read book Nucleic Acid Polymerases written by Katsuhiko S. Murakami and published by Springer Science & Business Media. This book was released on 2013-10-22 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a review of the multitude of nucleic acid polymerases, including DNA and RNA polymerases from Archea, Bacteria and Eukaryota, mitochondrial and viral polymerases, and other specialized polymerases such as telomerase, template-independent terminal nucleotidyl transferase and RNA self-replication ribozyme. Although many books cover several different types of polymerases, no book so far has attempted to catalog all nucleic acid polymerases. The goal of this book is to be the top reference work for postgraduate students, postdocs, and principle investigators who study polymerases of all varieties. In other words, this book is for polymerase fans by polymerase fans. Nucleic acid polymerases play a fundamental role in genome replication, maintenance, gene expression and regulation. Throughout evolution these enzymes have been pivotal in transforming life towards RNA self-replicating systems as well as into more stable DNA genomes. These enzymes are generally extremely efficient and accurate in RNA transcription and DNA replication and share common kinetic and structural features. How catalysis can be so amazingly fast without loss of specificity is a question that has intrigued researchers for over 60 years. Certain specialized polymerases that play a critical role in cellular metabolism are used for diverse biotechnological applications and are therefore an essential tool for research.

Download or read book Influenza Virus written by Yoshihiro Kawaoka and published by Humana Press. This book was released on 2016-08-23 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reports of influenza-like illnesses date back to the Middle Ages, and outbreaks of influenza likely afflicted humans long before that. Over the last half century, influenza virus research has led to the development of two classes of antivirals – ion channel and neuraminidase inhibitors. Recently, a method of the artificial generation of an influenza virus was established. This system has been instrumental in the development of novel influenza vaccines and in the understanding of viral pathogenicity and the functions of viral proteins. Influenza Virus: Methods and Protocols summarizes the current techniques that have made this progress possible, ranging from protocols for virus isolation, growth, and subtyping to procedures for the efficient generation of any influenza virus. Written in the successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Influenza Virus: Methods and Protocols seeks to serve both professionals and novices with the techniques used in numerous laboratories around the world that are, thus, the building blocks that underpin almost all influenza virus research.

Available in PDF, EPUB and Kindle. Book excerpt: Since the identification of the first cases of the coronavirus in December 2019, there has been a significant amount of confusion regarding the origin and spread of the so-called 'coronavirus', SARS-CoV-2, and the cause of the disease COVID-19. Conflicting messages from the media and officials across different countries and organizations, the abundance of disparate sources of information, unfounded conspiracy theories on the origins of the virus, unproven therapies, and inconsistent public health measures, have all served to increase anxiety in the population. Where did the virus come from? How is it transmitted? How does it cause disease? Is it like flu? What is a pandemic? In this concise and accessible introduction, a leading expert provides answers to these commonly asked questions. This revised and updated edition now also covers how the virus mutates, how important these mutations are, how vaccines work, and what we can expect in the near and long-term future.

Book excerpt: RNA viruses cause a variety of acute and chronic diseases in humans. In addition to encoding for viral proteins, the genomes of RNA viruses often harbor secondary and tertiary RNA structures that have been associated with functions essential for successful virus replication and propagation. While antiviral research has focused almost exclusively on targeting viral proteins, the importance of RNA structural elements in virus lifecycles suggest these motifs could be promising therapeutic targets. In this thesis, I will dissect the contributions and druggability of RNA structures and complexes in two distinct phases of the viral lifecycle: first, in the virus packaging and production of influenza A virus (IAV), a negative-strand segmented RNA virus responsible for severe, sometimes fatal respiratory disease with pandemic potential; and second, in the replication complex of hepatitis C virus (HCV), a positive-strand RNA virus associated with chronic liver disease and cancer. To characterize the role of RNA secondary structures in IAV virus packaging, I employed the chemical mapping technique, Selective 2′ Hydroxyl Acylation analyzed by Primer Extension (SHAPE), which uses experimental probing data to guide computational modeling of high resolution RNA structure. This method enabled me to determine the RNA secondary structure of the IAV 5′ packaging signal region of virus genome segment PB2, the structures of known mutations in PB2 that disrupt virus packaging, as well as the discovery and characterization of novel mutants. Cutting-edge multidimensional mapping methods, Mutate-and-Map and Mutate-Map-Rescue, built upon this technical base and provided structural validation through discovery of compensatory mutant partners, which later informed both the in vivo exploration of packaging-defective viruses, as well as the design of locked nucleic acids (LNAs) targeting this structure. In vitro and in vivo drug targeting by LNAs of this IAV packaging signal structure exhibited powerful prophylactic and therapeutic efficacy. Combined, this work points to the promise of RNA secondary structures as valid antiviral targets, and sheds new light on IAV genome packaging mechanisms. The second section of my thesis built upon previous research in the lab. SHAPE was again employed to map both the RNA secondary structure of the HCV 5′ internal ribosomal entry site (IRES) and the structural interaction between the virus's 5′ untranslated region (UTR) and the miR-122 complex found to mediate viral replication. As an extension of this investigation, we sought to better parse the interaction of the viral replication complex with the host membrane in real-time. To do so, we employed a supported lipid-bilayer (SLB) platform and coupled it with quartz crystal microbalance with dissipation (QCM-D) to reconstitute and explore how components of the HCV replicase complex affect viral RNA replication and in vitro RNA transcription. The core enzyme of this complex, the NS5B RNA-dependent RNA polymerase, is required for in vivo virus replication and is a prime drug target for current and future HCV antiviral therapies. The reconstitution of full length NS5B in a membranous environment capable of active polymerase function, however, had not been demonstrated. Here, the SLB/QCM-D platform made it possible to reconstruct an in silico biological mimic of the host membrane to quantitatively probe and observe interactions between the membrane, the HCV viral RNA template and its associated viral proteins in real time. Together, these provide strong proof-of-concept for use of this technique in further understanding of the molecular details of HCV genome replication and future drug screening applications.

This book was released on 2011-09-01 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Influenza continues to be an ongoing problem despite the existence of vaccines and drugs. Disease outbreaks can occur relatively quickly as witnessed with the recent emergence of the influenza virus A/H1N1 pandemic. The development of new anti-influenza drugs is thus a major challenge. This volume describes all aspects of the virus structure and function relevant to infection. The focus is on drug discovery of inhibitors to the enzyme sialidase, which plays a key role in the infectious lifecycle of the virus. Following an overview of the influenza virus, the haemagglutinin, the interactions with the cell receptors and the enzymology of virus sialidase, recent results in drug design are presented. These include a full coverage of the design, synthesis and evaluation of carbohydrate as well as non-carbohydrate influenza virus sialidase inhibitors. Further reviews of the clinical experience with influenza virus sialidase inhibitors and of the development of resistance to these inhibitor drugs complement the topic.

Download or read book Measles Virus written by Volker ter Meulen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measles, also called the greatest killer of children in history, still annually affects about 50 million individuals and causes close to a million deaths primarily in developing countries. Before the advent of measles vaccine some 30 years ago, these figures were roughly three times higher. Attenuated measles virus (MV) strains, all quite closely related to the original Edmonston isolate, have a very good record as a safe and highly efficacious vaccine and have brought down the measles toll in industrialized countries to almost negligible levels. However, recent outbreaks in the USA and Europe have again brought the measles problem to public attention. Sadly enough, these outbreaks were more instrumental in inducing activities to drastically reduce and hopefully finally eradicate measles than were the ten thousand times higher number of victims in developing countries. To reach this goal, as detailed in this volume, apparently it is not enough to of the existing vaccine as was the rigorously enforce use case with smallpox eradication: the intricacies of measles disease phenomena, in particular the generalized immune suppression which favors secondary infections, require more basic knowledge of the virus-host interactions and probably the development of new vaccines for special applications such as first immunizations of very young infants in developing countries.

Available in PDF, EPUB and Kindle. Book excerpt: Coronaviruses were recognized as a group of enveloped, RNA viruses in 1968 and accepted by the International Committee on the Taxonomy of Viruses as a separate family, the Coronaviridae, in 1975. By 1978, it had become evident that the coronavirus genomic RNA was infectious (i. e. , positive strand), and by 1983, at least the framework of the coronavirus replication strategy had been per ceived. Subsequently, with the application of recombinant DNA techniques, there have been remarkable advances in our understanding of the molecular biology of coronaviruses, and a mass of structural data concerning coronavirus genomes, mRNAs, and pro teins now exists. More recently, attention has been focused on the role of essential and accessory gene products in the coronavirus replication cyde and a molecular analysis of the structure-function relation ships of coronavirus proteins. Nevertheless, there are still large gaps in our knowledge, for instance, in areas such as the genesis of coronavirus subgenomic mRNAs or the function of the coronavirus RNA-dependent RNA polymerase. The diseases caused by coronaviruses have been known for much longer than the agents themselves. Possibly the first coronavirus-related disease to be recorded was feline infectious peritonitis, as early as 1912. The diseases associ ated with infectious bronchitis virus, transmissible gastroenteritis virus, and murine hepatitis virus were all well known before 1950.
