Viruses and RNAi share an intricate relationship at many levels. RNAi is an important antiviral defense mechanism in plants and invertebrates, microRNAs – of viral or cellular origin – affect many aspects of virus biology, and replication of many, if not all, mammalian viruses can be suppressed by RNAi. Antiviral RNAi: Concepts, Methods, and Applications provides a collection of protocols for the analysis of viral small RNAs and natural antiviral RNAi responses as well as for the development and optimization of RNAi-based antiviral drugs. As RNAi is a central regulatory mechanism in the cell, the methods in this volume can also be applied out of the context of a virus infection. Divided into five convenient parts, this detailed volume reviews important basic concepts in the field of antiviral RNAi, provides experimental and bio-informatic tools for the analysis of small silencing RNAs, covers methods to biochemically dissect RNAi-based antiviral defense and viral counter-defense mechanisms, describes methods for the design, expression, and delivery of therapeutic antiviral siRNAs, and finally presents genome-wide RNAi approaches for the identification of factors involved in virus replication. Written in the highly successful Methods in Molecular BiologyTM series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, Antiviral RNAi: Concepts, Methods, and Applications serves as an ideal guide for both novice and experienced researchers alike striving to dissect the role of RNAi in the viral life cycle or to further boost the development of novel therapeutics and experimental tools based on RNAi technology.

Gene Therapy for Viral Infections provides a comprehensive review of the broader field of nucleic acid and its use in treating viral infections.

Viral respiratory tract infections are important and common causes of morbidity and mortality worldwide. In the past two decades, several novel viral respiratory infections have emerged with epidemic potential that threaten global health security. This Monograph aims to provide an up-to-date and comprehensive overview of severe acute respiratory syndrome, Middle East respiratory syndrome and other viral respiratory infections, including seasonal influenza, avian influenza, respiratory syncytial virus and human rhinovirus, through six chapters written by authoritative experts from around the globe.

RNA interference (RNAi) is the most recent discovery to revolutionize the study of biology. In this book, leaders in the field contribute state-of-the-art, easy to follow methods and bench protocols designed for practical, everyday use of RNAi in biological research. Cutting edge and clearly written, this book enables a researcher with standard molecular biological training to perform major RNAi-related experiments and contribute to this revolutionary, growing field.

A crucial issue for antiviral therapy is the fact that all antiviral substances rapidly select for resistance; thus, monitoring and overcoming resistance has become a most important clinical paradigm of antiviral therapy. This calls for cautious use of antiviral drugs and implementation of combination therapies. In parallel, efforts in drug discovery have to be continued to develop compounds with novel mode-of-action and activity against resistant strains. This book reviews the current status of antiviral therapy, from the roads to development of new compounds to their clinical use and cost effectiveness. Individual chapters address in more detail all available drug classes and outline new approaches currently under development.

RNAi technology is used for large-scale screens that systematically shut down each gene in the cell, which can help identify the components necessary for a particular cellular process or an event such as cell division. Exploitation of the pathway is also a promising tool in biotechnology and medicine. Introducing new technology in the study of RNA

The enormous potential of siRNA as a therapeutic has led to an explosion of interest from the scientific community. There has been intense interest from Big Pharma to capitalise on this new technology but the fact remains that delivery is a key determinant in realizing the full clinical potential of RNA interference. There is an urgent need for better delivery methods to take this technology forward. This book addresses the role of different RNAi molecules in cellular processes as rational for diagnostic and therapeutic approaches. This book will cover RNAi therapeutic design to optimize siRNA potency and reduce off-target effects and current delivery technologies to overcome both intracellular and extracellular barriers. The reader will gain an insight into RNA interference from the cellular mechanisms to screening to siRNA design right through to diagnostic and therapeutic applications.
