This book was released on 2012 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gammaherpesviruses are clinically important human pathogens associated with multiple types of tumors. The life cycle of gammaherpesviruses consists of two distinct phases, latency and lytic replication, both of which are important for the viral-associated pathogenesis. Murine gammaherpesvirus 68 (MHV-68) has been used as a model to study virus-host interactions of human gammaherpesviruses because of its genomic and biological similarities. During the course of MHV-68 lytic infection, the virus is highly dependent on cellular machinery to facilitate its replication. Host cells, on the other hand, develop mechanisms to sense and restrict virus replication. Here, we present an integrative systems approach to elucidate the interactions between MHV-68 and its host. Our previous yeast-two-hybrid analysis and genome-wide expression profiling implicated hundreds of cellular factors mediating virus-host interactions. Among the cellular factors identified, those involved in kinase- and transcription factor- regulated signaling are the most highly enriched. Therefore, high-throughput screens of cellular kinome and transcription factors cDNA and siRNA libraries were carried out, which uncovered 125 MHV-68 dependency factors and 213 restriction factors. We found that many cellular factors affect MHV-68 replication by regulating RTA transcription. Characterization of this subset of genes showed they also play roles in KSHV latency maintenance and reactivation. Furthermore, cellular factors regulating later steps of viral replication, such as viral late gene expression and egress, were also identified and validated. Finally we compared the viral restriction factors to the results of a kinome siRNA screen designed to identify cellular regulators of innate immune response to cytosolic DNA. Remarkably, 23 genes were found among the top 10% of the hits of both screens. The MHV-68 restriction factor RIOK3 was confirmed to play a role in IRF3 activation and type I interferon induction mediated by both cytosolic DNA and RNA. RIOK3 is required for cellular antiviral response to both DNA virus (MHV-68) and RNA virus (Influenza A), suggesting a central role in innate immunity. Further analysis revealed that RIOK3 complexes with TBK1 and IRF3, bridging the activity between the two. Collectively, this multilayered approach unfolded a comprehensive map of gammaherpesvirus-host interactions which will provide basis for developing new anti-viral therapies.

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 Epigenetics of Infectious Diseases written by Walter Doerfler and published by Springer. This book was released on 2017-05-26 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume of Epigenetics and Human Health is devoted to the patho-epigenetics of viral and microbial infections, an exiting new field of disease-related epigenetic research. As recognized during the past years, epigenetic reprogramming of pathogen and host genome functions – the latter frequently induced by pathogens – plays an important role in many infectious processes. Beyond their immediate relevance for pathogen proliferation and obligatorily associated symptoms, such alterations frequently contribute to severe additional complications, such as the development of immunodeficiency, cancer and various chronic disorders. This holds in particular for epigenetic dysregulation of host gene expression induced by latent infections. The present book summarizes current knowledge of the mechanisms underlying epigenetic changes caused by viral, bacterial, fungal and protozoan infections and their impact on human health.
