Zika Virus and Host Interactions


Book Description

Zika virus (ZIKV), one of the flavivirus family members transmitted by mosquitos, was declared a Public Health Emergency of International Concern by the WHO in February 2016 because of clusters of newborn microcephaly cases and other neurological disorders in Brazil. Most ZIKV infections result in a self-limited flu-like febrile disease, however, if contracted during pregnancy, the virus can also infect fetuses and cause a spectrum of birth defects known as congenital Zika syndrome. To date, no vaccines or antiviral drugs are licensed for ZIKV, and the virus has spread and become endemic to many tropical and sub-tropical countries. Included in this book are thirteen reports addressing diverse aspects of ZIKV–host interactions. These studies range from basic science to clinical research. It is expected that findings from these studies will contribute to a better understanding of the host cells interacting with ZIKV, and may serve as the basis for new diagnostics, antiviral therapies, and vaccine design.




Japanese Encephalitis and West Nile Viruses


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.




New Advances on Zika Virus Research


Book Description

Zika virus (ZIKV) is a mosquito-borne member of the Flaviviridae family that historically has been associated with mild febrile illness. However, the recent outbreaks in Brazil in 2015 and its rapid spread throughout South and Central America and the Caribbean, together with its association with severe neurological disorders—including fetal microcephaly and Guillain-Barré syndrome in adults—have changed the historic perspective of ZIKV. Currently, ZIKV is considered an important public health concern that has the potential to affect millions of people worldwide. The significance of ZIKV in human health and the lack of approved vaccines and/or antiviral drugs to combat ZIKV infection have triggered a global effort to develop effective countermeasures to prevent and/or treat ZIKV infection. In this Special Issue of Viruses, we have assembled a collection of 32 research and review articles that cover the more recent advances on ZIKV molecular biology, replication and transmission, virus–host interactions, pathogenesis, epidemiology, vaccine development, antivirals, and viral diagnosis.




Membrane Fusion


Book Description

Featuring sections on the general properties of membranes and applications of membrane fusion techniques, this sourcebook outl







Dengue and Zika: Control and Antiviral Treatment Strategies


Book Description

This contributed volume contains 25 chapters from leading international scientists working on dengue and Zika viruses, who came together in Praia do Tofo in Mozambique to discuss the latest developments in the fields of epidemiology, pathogenesis, structural virology, immunology, antiviral drug discovery and development, vaccine efficacy, and mosquito control programs. The meeting venue offered an opportunity to discuss current research on these flaviviruses in an idyllic setting, and also to develop first-hand appreciation of the issues in infectious diseases facing developing countries and of the research gaps in Africa. For readers, who should include basic and clinical researchers in the field and public health professionals, the chapters are organized to provide a comprehensive overview of the various topics in current dengue and Zika virus research. A unique feature of the proceedings of this meeting is the inclusion of the discussions that took place following presentations. These have been transcribed and appended to the end of the relevant chapters, and they form the “salt in the soup” of this book.




Advanced Concepts in Human Immunology: Prospects for Disease Control


Book Description

This book highlights information derived primarily from clinical samples, with particular reference to theoretical and scientific aspects of the human immune system. This text will focus on topics that range from host-pathogen interactions in infectious disease to host immune response in cancer, allergic diseases, neuroinflammatory diseases, and autoimmune disorders. The reader will also have a well-rounded understanding of the behavior of the immune system with particular emphasis on the role of immunoproteomics in immunotherapy, neuroprotective immunity for neurodegenerative and neuroinfectious disease, leukemia-associated dendritic cell induction of adaptive immunity dysregulation, and the role of immune checkpoint inhibitors in cancer, infection, as well as neuroinflammation. Taken together, the contents of this book are intended for both clinicians and researchers in academia and industry.




Guideline: infant feeding in areas of Zika virus transmission


Book Description

The objective of this guideline is to provide global, science-informed recommendations on infant feeding in areas of Zika virus transmission. The primary audience of this guideline is health professionals responsible for developing national and local health protocols, especially those related to infant feeding in infancy and early childhood. The primary audience also includes those directly providing care to infants, such as nurses, general medical practitioners, paediatricians, managers of maternal, newborn and child health programmes and relevant personnel in health ministries, in all settings. Lastly, this guideline is also of interest to pregnant or breastfeeding women living or travelling to areas where Zika virus transmission continues. This guideline aims to help WHO Member States and their partners to make science-informed decisions on the appropriate actions in their efforts to achieve the Sustainable Development Goals, the resolutions of the World Health Assembly on infant and young child feeding and the global targets put forward in the comprehensive implementation plan on maternal, infant and young child nutrition, the global strategy for infant and young child feeding and the Zika Strategic Response Plan.




Virus as Populations


Book Description

Virus as Composition, Complexity, Quasispecies, Dynamics, and Biological Implications, Second Edition, explains the fundamental concepts surrounding viruses as complex populations during replication in infected hosts. Fundamental phenomena in virus behavior, such as adaptation to changing environments, capacity to produce disease, and the probability to be transmitted or respond to treatment all depend on virus population numbers. Concepts such as quasispecies dynamics, mutations rates, viral fitness, the effect of bottleneck events, population numbers in virus transmission and disease emergence, and new antiviral strategies are included. The book's main concepts are framed by recent observations on general virus diversity derived from metagenomic studies and current views on the origin and role of viruses in the evolution of the biosphere. - Features current views on key steps in the origin of life and origins of viruses - Includes examples relating ancestral features of viruses with their current adaptive capacity - Explains complex phenomena in an organized and coherent fashion that is easy to comprehend and enjoyable to read - Considers quasispecies as a framework to understand virus adaptability and disease processes




RNA Worlds


Book Description

This volume reviews our understanding of two RNA worlds: the primordial RNA world before DNA, in which RNA was both information store and biocatalyst; and the contemporary RNA world, in which mRNA, tRNA, rRNA, siRNA, miRNA, and a host of other RNAs operate.
