Book Description
Human cytomegalovirus (HCMV) infection in newborns and immunocompromised individuals with immature or deficient immune systems can cause life-threatening diseases. The clinical and subsequent economical burden of HCMV infection led the US Institute of Medicine designating a vaccine for HCMV as the highest level of priority. Complex virus-host interactions have developed over millions of years of co-evolution, making the understanding of the pathogenesis of HCMV disease particularly challenging. Consequently, a crucial factor in aiding the development of effective vaccinations and therapies to significantly reduce morbidity and mortality associated with HCMV infection is elucidating what immune mechanisms contribute to/impede protection against infection. For example, is the induction of immunomodulatory agents such as cytokines beneficial or harmful to the host during infection? Given the known immunosuppressive properties of one such cytokine, interleukin-10 (IL-10), in conjunction with the evolutionary acquisition by HCMV of its own IL-10 homologue, I hypothesised that mammalian- and viral-IL-10 suppress protective immunity during acute CMV infection. Utilising a mouse model of CMV infection, I revealed a surprising antiviral role for IL-10 during acute infection in vivo, which was achieved via limitation of activation-induced death of NK cells. The IL-10-related cytokine interleukin-22 (IL-22) provides critical protection against certain infectious agents and I therefore hypothesised that IL-22 provides protective immunity during acute CMV infection. Utilising the murine infection model once more, I discovered a tissue-specific antiviral role for IL-22 during acute infection in vivo and made the surprising finding that neutrophils play a protective role during infection. I also demonstrated that neutrophils can directly inhibit viral replication in vitro. Thus, novel insights into cytokine biology in the context of viral infections in vivo revealed by these studies highlighted important considerations for future research into herpesvirus infections, and has major implications for the treatment of this important infectious disease.

Book Description
This comprehensive account of the human herpesviruses provides an encyclopedic overview of their basic virology and clinical manifestations. This group of viruses includes human simplex type 1 and 2, Epstein–Barr virus, Kaposi's Sarcoma-associated herpesvirus, cytomegalovirus, HHV6A, 6B and 7, and varicella-zoster virus. The viral diseases and cancers they cause are significant and often recurrent. Their prevalence in the developed world accounts for a major burden of disease, and as a result there is a great deal of research into the pathophysiology of infection and immunobiology. Another important area covered within this volume concerns antiviral therapy and the development of vaccines. All these aspects are covered in depth, both scientifically and in terms of clinical guidelines for patient care. The text is illustrated generously throughout and is fully referenced to the latest research and developments.

Book Description
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.

Book Description
Overall recent research on TLRs has led to tremendous increase in our understanding of early steps in pathogen recognition and will presumably lead to potent TLR targeting therapeutics in the future. This book reviews and highlights our recent understanding on the function and ligands of TLRs as well as their role in autoimmunity, dendritic cell activation and target structures for therapeutic intervention.

Book Description
The study of antiviral drug resistance has provided important insights into the structure of virus enzymes, the functions of certain genes, mechanisms of action of antiviral drugs, the design of new antiviral compounds and the pathogenesis of viral diseases. The emergence of resistant strains must be explored at all stages of drug development: during the preclinical evaluation of candidate compounds; during the early clinical evaluation of new drugs; and as part of epidemiological surveillance for the prevalence of resistance during use of approved treatments. Accumulating understanding of antiviral drug resistance thus reflects progress in the chemotherapy of viral infection. Antiviral Drug Resistance provides state-of-the-art coverage of the basic and clinical aspects of this subject. It deals with the basic science, including the mechanisms of drug resistance and drug action, genetics of drug resistance, cross resistance, and X-ray crystallographic structural aspects of resistance, as well as the clinical aspects, including issues of assay of susceptibility of clinical isolates, descriptive aspects of emergence of reduced susceptibility, and clinical significance and impact of resistance. As such this unique volume will be essential to basic researchers in drug discovery and viral pathogenesis, as well as clinicians involved in antiviral chemotherapy.

Book Description
This book provides researchers the opportunity to investigate type-2-associated diseases in their laboratories. Beginning with chapters describing various models of type-2 immunity, the volume then continues by detailing cellular protocols designed to identify, characterize, and assess the function of key adaptive and innate immune cells involved in type-2 inflammation; approaches to isolate and evaluate specific cellular subsets at the genetic, epigenetic, and molecular level; protocols to assess type-2 immunity and its relationship to organismal and metabolic systems (ex. Microbiome). This book concludes with a section that explores the use of primary human cells in evaluating relevance to the clinic. Written in the highly successful Methods in Molecular Biology series format, 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. Vital and authoritative, Type 2 Immunity: Methods and Protocols aims to provide a broad network of methods that can be used to develop a hypothesis and investigate its potential from bench to beside.
