The Viral Evasion Of Antiviral Innate Immunity

This Research Topic is the second volume of the “Community Series in Antiviral Innate Immune Sensing, Regulation, and Viral Immune Evasion”. Please see the first volume here. The innate immune system is crucial to defend against viruses or other pathogenic microbes in the early phases of infection. The response starts with detecting evolutionarily conserved structures, termed pathogen-associated molecular patterns (PAMPs), by a set of germline-encoded pattern-recognition receptors (PRRs). Following the detection of specific viral PAMPs, PRRs trigger the activation of intracellular signaling cascades, ultimately leading to the induction of type I interferons (IFNs), pro-inflammatory cytokines, and antiviral genes through the activation of interferon regulatory factor 3 (IRF3) and IRF7. Antiviral pathways need to be tightly regulated to ensure successful antiviral defenses and avoid aberrant or dysregulation of host immune signaling. We believe that the Research Topic will give updated insights into the dynamic fields of PAMPs sensing in antiviral innate immunity and viral immune evasion. We hope it will serve the purpose of encouraging new research. This Research Topic will provide an overall picture of antiviral innate immune sensing signal pathways, regulation, and viral immune evasion. We welcome the submission of Original Research, Review, Mini-Review, Hypothesis and Theory, and Perspective articles that cover, but are not limited to, the following subtopics:

The discovery of Toll-like receptors (TLRs) in the late 1990s ushered in a new age of discovery for innate immunity. The importance of TLRs for immunology and biomedical research was recognized with the Nobel Prize for Medicine or Physiology in 2011. The prize was shared by three scientists: Ralph Steinman (for the discovery of dendritic cells, whi

This book explores methods to study the complex and evolving interplay between a virus and its host that range from model systems to the detection of chemical molecules. The collection starts with the application of humanized mice and zebrafish as model organisms to study virus-host interactions and induction of innate immune responses. Subsequent chapters outline diverse methods to detect small interfering RNAs, microRNAs, and virus-derived dsRNA from a variety of cells, tissues, and organisms, as well as to interrogating the cytosolic RNA and DNA sensing pathways, including using RNA PAMPs as molecular tools, purification of cGAMP from virus particles and infected cells, and mechanisms to visualize the subcellular localization and activation of the adaptor proteins MAVS and STING. Cutting-edge methods, including high-throughput and genome-wide CRISPR/Cas9 screens, chromosome conformation capture, and whole-exome sequencing, are described to identify novel mediators, pathways, and variants underlying host susceptibility. Given the importance of studying these pathways and players under physiologic conditions, methods describing the isolation of primary mouse sensory neurons and group 2 innate lymphoid cells are also provided. Finally, this collection comes full circle back to the whole organism level and concludes with epidemiological methods to investigate virus-host interactions and the induction of innate immunity. Written for the Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Innate Antiviral Immunity: Methods and Protocols spans a diverse array of approaches to study and elucidate the intricacies of this vital area of study. The chapter 'Morphological Separation of Clustered Nuclei in Histological Images' is published open access under a CC BY 4.0 license at link.springer.com.

Based on the highly successful reference work Viral Pathogenesis published in 1997, this concise, economical version can be used both as an introductory text or for self-education by medical students and biologists alike. This latest edition provides a completely revised overview of the subject with new chapters on innate immunity, emerging viral diseases, and antiviral therapy in a format that is easy to understand without continually referring to additional information. Used by the author in his graduate classes at the University of Pennsylvania, it sets forth the essential principles and discusses the details of how the immune system responds to viral invasion including the treatment and prevention of infection. Illustrated by pertinent examples it is one of the only books devoted exclusively to this topic. * Offers almost a 20% expansion over the first edition * Focuses specifically on viral pathogenesis unlike other texts where only a few chapters are devoted to the topic * Neal Nathanson is one of the primary authorities in the field and has authored chapters on viral pathogenesis in two of the most well known virology and microbiology titles Field's Virology and Topley and Wilson's Microbiology * Now in four color throughout!
