Available in PDF, EPUB and Kindle. Book excerpt: In latent infection, HSV-1 undergoes epigenetic silencing as a means to suppress gene expression and persist in neurons. Surprisingly, in this study, we find that ICP0-null viruses accumulate less heterochromatin on lytic gene promoters relative to WT viruses. This suggests that ICP0 may function to promote infection of neurons, or assist in the establishment or maintenance of latent infection.

Available in PDF, EPUB and Kindle. Book excerpt: Primary herpes simplex virus 1 (HSV-1) infections are common in childhood, affecting mainly the oropharyngeal mucosa. The virus is then transported to the neuronal bodies in the trigeminal ganglia, where it establishes lifelong latency. Although latent infections are asymptomatic, HSV-1 reactivates upon a variety of stresses, producing recrudescence of disease and spreading infection. Lytic infections are treated with several drugs, but latency and reactivation cannot be cured or prevented. HSV-1 chromatin and epigenetic regulation during lytic and latent infections have been studied for decades. HSV-1 genomes are regularly chromatinized into inaccessible chromatin during latency but become more accessible during reactivation. Epigenetics thus likely play a major role in the regulation of HSV-1 transcription, replication, and reactivation from latency. Although HSV-1 DNA is non-regularly chromatinized in lytic infections, most current models assume a similar epigenetic regulation for HSV-1 as for cells. To evaluate the chromatinization of HSV-1 genomes during lytic infections, I performed nuclease protection assay coupled with bio-physical fractionation, to separate viral DNA-nucleoprotein complexes by hydrodynamic ratios, followed by deep sequencing (in collaboration with Dr. Depledge) of each fraction. Gene sampling and cluster analyses indicated that chromatin dynamics relate to the transcriptional competency of HSV-1 genomes, not the transcriptional levels of any individual genes or groups of genes. The transcriptionally competent genomes are in highly dynamic, and accessible, chromatin and the incompetent ones in far less dynamic, or accessible, chromatin. Moreover, chromatin insulator elements such as the CCCTC binding factor (CTCF) flank highly transcribed genome regions from mostly non-transcribed ones. My findings indicate that chromatin is a key regulator of HSV-1 transcription during lytic infections in that chromatin provide a first level of regulation, dictating transcriptional competency. I thus uncovered a new level of viral transcription regulation. During reactivation, the HSV-1 chromatin also changes from regular, mostly inaccessible, chromatin to a far more dynamic, and accessible, state. My findings during the lytic infections thus also provide a framework to better understand HSV-1 latency and reactivation.
Download or read book Human Herpesviruses written by Ann Arvin and published by Cambridge University Press. This book was released on 2007-08-16 with total page 1325 pages. 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.
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.

Book excerpt: Psychoneuroimmunology, Second Edition presents reports on the relationship between the nervous and immune systems. The book is divided into four sections. The first section details the role of neural structures and neurotransmitter signals in communication with the immune system. It documents the extensive neural connections with organs of the immune system; the dynamics of noradrenergic sympathetic innervation of spleen and thymus; and the evidence for immune signaling of the CNS. Part II elaborates the role of hormones in the modulation of immune functions; the basis for bidirectional communication between the neuroendocrine and immune systems; and the potential physiological implications of these neuroendocrine-immune system interactions. The third part addresses behavioral influences on immune response; the effects of conditioning, stress and social interactions in modulating immune responses; and the behavioral consequences of experimentally altered or genetically determined immunologic states. The final section presents the effects of psychosocial factors on immune responses and the potential impact of behavioral interventions in modulating immunity in healthy human subjects and in patients with AIDS. Neuroscientists, endocrinologists, and immunologists will find the book interesting.
Download or read book Epstein Barr Virus Volume 1 written by Christian Münz and published by Springer. This book was released on 2015-10-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Epstein Barr virus (EBV) was discovered as the first human tumor virus around 50 years ago. Since its discovery in Burkitt’s lymphoma it has been associated with various other malignancies, infectious mononucleosis and even autoimmune diseases. The two book volumes on EBV summarize the first 50 years of research on this tumor virus, starting with historical perspectives on discovery, oncogenicity and immune control, reviewing the role that the virus plays in the various associated diseases and concluding with a discussion on how the immune system keeps persistent EBV infection under control in healthy EBV carriers and can be used to treat EBV associated diseases. The respective 32 chapters are written by international experts from three continents for health care providers, biomedical researchers and patients that are affected by EBV. The assembled knowledge should help to understand EBV associated diseases better and to develop EBV specific vaccination in the near future.

Download or read book DNA Methylation and Complex Human Disease written by Michel Neidhart and published by Academic Press. This book was released on 2015-08-11 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: DNA Methylation and Complex Human Disease reviews the possibilities of methyl-group-based epigenetic biomarkers of major diseases, tailored epigenetic therapies, and the future uses of high-throughput methylome technologies. This volume includes many pertinent advances in disease-bearing research, including obesity, type II diabetes, schizophrenia, and autoimmunity. DNA methylation is also discussed as a plasma and serum test for non-invasive screening, diagnostic and prognostic tests, as compared to biopsy-driven gene expression analysis, factors which have led to the use of DNA methylation as a potential tool for determining cancer risk, and diagnosis between benign and malignant disease. Therapies are at the heart of this volume and the possibilities of DNA demethylation. In cancer, unlike genetic mutations, DNA methylation and histone modifications are reversible and thus have shown great potential in the race for effective treatments. In addition, the authors present the importance of high-throughput methylome analysis, not only in cancer, but also in non-neoplastic diseases such as rheumatoid arthritis. - Discusses breaking biomarker research in major disease families of current health concern and research interest, including obesity, type II diabetes, schizophrenia, and autoimmunity - Summarizes advances not only relevant to cancer, but also in non-neoplastic disease, currently an emerging field - Describes wholly new concepts, including the linking of metabolic pathways with epigenetics - Provides translational researchers with the knowledge of both basic research and clinic applications of DNA methylation in human diseases
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 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.
