Book Description
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.

Book Description
Japanese encephalitis and West Nile viruses are members of the Japanese encephalitis serological group of the genus Flavivirus and therefore closely related genetically and antigenically. They share a number of properties, including the use of birds as their major wildlife maintenance host and Culicine mosquitoes for transmission, and they are both associated with severe human disease, as well as fatal infections in horses. The emergence of these two viruses, and their well-established propensity to colonise new areas, make it timely to re-examine their ecology, biology, molecular structure, replication and epidemiology, and these therefore provide the focus of this volume.

Book Description
Viral Pathogenesis: From Basics to Systems Biology, Third Edition, has been thoroughly updated to cover topical advances in the evolving field of viral pathogenesis, while also providing the requisite classic foundational information for which it is recognized. The book provides key coverage of the newfound ability to profile molecular events on a system-wide scale, which has led to a deeper understanding of virus-host interactions, host signaling and molecular-interaction networks, and the role of host genetics in determining disease outcome. In addition, the content has been augmented with short chapters on seminal breakthroughs and profiles of their progenitors, as well as short commentaries on important or controversial issues in the field. Thus, the reader will be given a view of virology research with perspectives on issues such as biomedical ethics, public health policy, and human health. In summary, the third edition will give the student a sense of the exciting new perspectives on viral pathogenesis that have been provided by recent developments in genomics, computation, modeling, and systems biology. - Covers all aspects of viral infection, including viral entry, replication, and release, as well as innate and adaptive immunity and viral pathogenesis - Provides a fresh perspective on the approaches used to understand how viruses cause disease - Features molecular profiling techniques, whole genome sequencing, and innovative computational methods - Highlights the use of contemporary approaches and the insights they provide to the field

Book Description
[Truncate abstract] Flaviviruses are small, positive-stranded RNA viruses belonging to the family Flaviviridae. Flavivirus infection in humans could cause diseases ranging from febrile illnesses to fatal encephalitis. Mice provide a useful small animal model to study flavivirus-induced encephalitis in humans since mice also develop encephalitis during flavivirus infection. Some strains of mice have been shown to be resistant to flavivirus challenge and this resistance is conferred by a single autosomal dominant gene, designated as Flvr. Recently, OAS1b gene has been identified to be a gene candidate for Flvr. Several congenic resistant mouse strains have been developed by introducing resistance genes from outbred or wild mice onto the genetic background of susceptible C3H mice. These new resistant strains that carry different allelic variants at the Flv locus include C3H/PRI-Flvr (RV), C3H.MOLD-Flvmr (MOLD) and C3H.M.domesticus-Flvr-like (DUB), the latter two being developed in the same laboratory in which the work described in this thesis was accomplished. Preliminary studies in this laboratory found that flavivirus resistant mice are vulnerable to certain flavivirus infections, particularly when challenged by intracerebral (i.c.) route. Intracerebral (i.c.) challenge with flaviviruses such as West Nile virus (WNV) Sarafend strain and Kunjin virus (KUNV) MRM16 strain were found to induce high mortality in flavivirus resistant mice while infection with Murray Valley encephalitis virus (MVEV) OR2 strain did not cause any apparent disease in the same mice. ... Thus, it can be concluded that CD8+ T cells exerted harmful effect to resistant DUB mice during KUNV i.c. infection by producing excessive IFN[gamma] that could be toxic, causing functional loss of the CNS cells. It was shown from in vitro studies that WNV had the highest tropism for macrophages and dendritic cells, followed by KUNV. MVEV however did not replicate well in these cells. This combined with the data from the in vivo studies indicates that macrophages might be involved in the pathogenesis of intraperitoneal (i.p.) infection of WNV but not KUNV and MVEV. The reason for this could be that the production of KUNV in macrophages may not be high enough to induce viraemia and subsequent fatal encephalitis in mice. In contrast, MVEV appears to use different mechanism or cells for virus dissemination. Although macrophages may not be involved in KUNV pathogenesis after i.p. infection, the fact that macrophages support KUNV replication in vitro may indicate the possibility that blood-borne macrophages were recruited to the brain where they can get infected with KUNV during i.c. infection and therefore could participate in KUNV pathogenesis in DUB mice. This study provides evidence for the first time on the detrimental effect of host antiviral immunity and inflammatory mediators during flavivirus i.c. infection in resistant mice. However, it also launches a new question on the selective cell tropism of KUNV versus MVEV responsible for inducing different pattern of immune responses and consequently leading to different outcomes of infection in resistant mice.

Book Description
Flaviviruses are a diverse group of small RNA enveloped viruses, many of which are important human and animal pathogens. The best known include dengue virus, yellow fever virus, Japanese encephalitis virus, and West Nile virus. These viruses are endemic in many tropical and sub-tropical regions of the world. Dengue virus alone infects over 100 million people annually. In recent years, research on flaviviruses has progressed at a remarkable rate, leading to significant advances in our understanding of virus biology. This should ultimately lead to the development of better vaccine and antiviral strategies. This up-to-date and cutting-edge anthology contains contributions from the leading experts in the flavivirus field. Chapters are balanced by contributions from established investigators who have dedicated their careers to flavivirus research with those from newcomers who have recently made significant contributions to the flavivirus field. The book is divided into two sections: Molecular Virology and Virus Prevention. The first section on Molecular Virology covers: virion structure * virus replication * the NS1 glycoprotein * the NS3 protein * the NS5 protein * innate immunity and flavivirus infection * host responses to flavivirus infection * flavivirus fitness and transmission. The Virus Prevention section includes: vaccines * antibody therapy * small molecule antiviral development * flavivirus diagnostics * vector-virus interactions * vector control. The book represents an important update of flavivirus research and will serve as a reference to flavivirus researchers at the graduate level and beyond. It is a recommended text for all virology libraries.
