Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive account of the human herpesviruses provides an encyclopedic overview of their basic virology and clinical manifestations. This group of viruses includes human simplex type 1 and 2, Epstein–Barr virus, Kaposi's Sarcoma-associated herpesvirus, cytomegalovirus, HHV6A, 6B and 7, and varicella-zoster virus. The viral diseases and cancers they cause are significant and often recurrent. Their prevalence in the developed world accounts for a major burden of disease, and as a result there is a great deal of research into the pathophysiology of infection and immunobiology. Another important area covered within this volume concerns antiviral therapy and the development of vaccines. All these aspects are covered in depth, both scientifically and in terms of clinical guidelines for patient care. The text is illustrated generously throughout and is fully referenced to the latest research and developments.

Book excerpt: Herpes simplex virus type 1 (HSV-1) replicates in the nucleus and buds through the nuclear membrane to access the cytosol and complete the maturation process. The HSV-1 protein pUL31, along with its binding partner, pUL34, has been previously shown to be required for nucleocapsids to successfully bud through the nuclear membrane. pUL31 is also required for efficient viral DNA synthesis and packaging. After the HSV-1 exits the nucleus, the capsid acquires several accessory proteins (tegument) and finally a mature envelope by budding into vesicles of the trans-Golgi network (TGN). These virion-laden vesicles traffic toward the cell periphery and through cortical actin until ultimately the virion is secreted upon fusion of the TGN vesicle with the plasma membrane. The data presented here reveals new roles for pUL31, as cells infected with a UL31-null virus were delayed for viral gene expression as well as activation of NF[kappa]B and c-Jun N-terminal kinase (JNK) in multiple cell lines. At least one representative from each kinetic class of viral genes was examined at various times post infection. The protein expression defects were not caused by a failure to enter cells, was not rescued by ICP27 expressed in trans and correlated with NF[kappa]B activation. The data shows that these defects were not observed in the absence of the pUL31 binding partner, pUL34, and that while most pUL31 is expressed at late times post infection, low levels are detectable as early as 2 hours post infection. Data presented in this work also demonstrates a role for the actin motor myosin Va in the secretion of HSV-1 virions. Expression of two isoforms of dominant negative myosin Va (DN-myoVa) decreased virion secretion by 5075% as well as significantly decreased surface expression of viral glycoproteins B, M and D. DN-myoVa colocalized with TGN markers and the conformation of native myosin Va in infected cells was altered by 4 hours post infection. These data suggest that myosin Va is involved in the egress of virion-laden TGN vesicles as they transit through cortical actin toward the plasma membrane.

Download or read book The Epstein Barr Virus written by M. A. Epstein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Epstein-Barr virus was discovered 15 years ago. Since that time an immense body of information has been accumu lated on this agent which has come to assume great signifi cance in many different fields of biological science. Thus, the virus has very special relevance in human medicine and oncology, in tumor virology, in immunology, and in mole cular virology, since it is the cause of infectious mononu cleosis and also the first human cancer virus, etiologically related to endemic Burkitt's lymphoma and probably to nasopharyngeal carcinoma. In addition, continuous human lymphoid cell lines initiated and maintained by the transform ing function of the virus genome provide a laboratory tool with wide and ever-growing applications. Innumerable papers on the Epstein-Barr virus have ap peared over recent years and reports of work with this agent now constitute a veritable flood. The present book provides the first and only comprehensive, authoritative over-view of all aspects of the virus by authors who have been the original and major contributors in their particular disciplines. A complete and up-to-date survey of this unique and important agent is thus provided which should be of great interest to experts, teachers, and students engaged in cancer research, virology, immunology, molecular biology, epide miology, and cell culture. Where topics have been dealt with from more than one of these viewpoints, some inevitable overlap and duplication has resulted; although this has been kept to a minimum, it has been retained in some places because of positive usefulness.

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 Human Herpesviruses written by Yasushi Kawaguchi and published by Springer. This book was released on 2018-06-12 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces and reviews several topics for each human herpesvirus. One of the most important features of the book is that it covers aspects of both basic research and clinical medicine. Herpesviridae, a family of double-strand DNA viruses, has unique biological features by which these viruses establish latency after primary infection and reactivate in later life. Nine human herpesviruses are known so far, and each of them causes a variety of diseases in both primary infection and reactivation. Since the discovery of each human herpesvirus, an abundance of findings related to them has accumulated in basic research and clinical medicine. However, the vast majority of biological features is still masked in mystery. Furthermore, a strategy of treatment and prevention has not yet been established for most human herpesviruses. A wide range of readers will be interested in this volume with its treatment of problematic points and latest findings in the field.
Download or read book The Role of Tegument Proteins and the Dynamic Interplay They Have with One Another Throughout the Course of Herpes Simplex Virus Type 1 Infections written by Ekaette Francis Mbong and published by . This book was released on 2012 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herpes simplex virus type 1 (HSV-1) is a neurotropic virus affecting up to 98% of the adult population. Central to this report is the proteinaceous layer termed the tegument found within the HSV-1 virion. The tegument is composed of>20 different viral proteins of varying stoichiometries. Tegument proteins are delivered to the host cell upon infection, providing this virus an advantage early in its replication cycle. Tegument proteins also function at late times in infection when they are synthesized at high levels. One of the most abundant tegument proteins is VP22, encoded by the U_L 49 gene, with over 2000 copies per virion. The studies described herein provided much insight into how VP22 promotes the HSV-1 replication cycle. We found the absence of VP22 during infection resulted in decreased mRNA levels at early times and decreased protein synthesis at late times. These results were distinct and separable with respect to both the genes affected and the timing during infection. Because U_L 49^- infections often result in secondary, compensatory mutations in the gene encoding vhs, we examined the effects of one such mutation as well as the role of vhs's RNase activity on protein synthesis in the presence and absence of VP22. Our results indicated secondary mutations that decreased vhs's RNase activity compensated for the lack of VP22 during HSV-1 infections. Further analyses indicated the absence of VP22 resulted in decreased translation efficiency independent of mRNA abundance, the result of cleavage of the 5' UTRs of viral mRNAs. In separate studies we focused on the tegument protein encoded by the U_L21 gene. Although much is known about the role of this protein at late times in infection, very little was known about its role at early times in HSV-1 infections. We found the absence of pUL21 resulted in decreased levels of several immediate early mRNAs, and their corresponding proteins, at early times in infection. Although HSV-1 establishes a persistent infection, and is therefore incurable, we have made several novel findings that contribute important knowledge to the herpesvirus field and will hopefully aid in the development of new therapeutics.

Download or read book Characterization of the Role of Herpes Simplex Virus Protein VP16 in Viral Gene Expression Through Interactions with the Virion Host Shutoff Protein VHS and HCF 1 microform written by Jozo Knez and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2003 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herpes Simplex Virus 1 (HSV1) VP16 transcriptionally activates viral immediate-early (IE) genes, through the formation of a multi-protein structure termed the VP16-induced complex (VIC). VIC is comprised of cellular transcription factors Oct-1 and HCF-1. In addition, VP16 is a pre-formed, structural protein that has a critical role in virion assembly. At least one aspect of its role at late times post-infection includes the downregulation of the virion host shutoff protein (vhs); which functions to indiscriminately degrade mRNA.
