This Volume presents key microscopy and imaging methods for revealing the structure and ultrastructure of environmental and experimental samples, of microbial communities and cultures, and of individual cells. Method adaptations that specifically address problems concerning the hydrophobic components of samples are highlighted and discussed. The methods described range from electron microscopy and light and fluorescence microscopy, to confocal laser-scanning microscopy, and include experimental set-ups for the analysis of interfacial processes like microbial growth and activities at hydrocarbon:water interfaces, biofilms and microbe:mineral interfaces. Three forms of fluorescence in situ hybridization - CARD-FISH, MAR-FISH and Two-pass TSA-FISH - are described for the ecophysiological analysis of functionally active microbes in samples. The methods presented will enable readers to obtain an ultrastructural picture of, and identify the key functional microbes in, samples under investigation. This in turn will constitute a key framework for the interpretation of information from other experimental approaches, such as physicochemical analyses and genomic investigations. Hydrocarbon and Lipid Microbiology ProtocolsThere are tens of thousands of structurally different hydrocarbons, hydrocarbon derivatives and lipids, and a wide array of these molecules are required for cells to function. The global hydrocarbon cycle, which is largely driven by microorganisms, has a major impact on our environment and climate. Microbes are responsible for cleaning up the environmental pollution caused by the exploitation of hydrocarbon reservoirs and will also be pivotal in reducing our reliance on fossil fuels by providing biofuels, plastics and industrial chemicals. Gaining an understanding of the relevant functions of the wide range of microbes that produce, consume and modify hydrocarbons and related compounds will be key to responding to these challenges. This comprehensive collection of current and emerging protocols will facilitate acquisition of this understanding and exploitation of useful activities of such microbes.

Written by specialists in the different fields, this book presents new perspectives and insights into strategies and weapons to fight microbial infections. It also reviews the "state of the art" of alternative treatment approaches and new therapeutic agents to deal with infections caused by multidrug-resistant microorganisms. In an era of accumulated resistance to current antibiotics, it is vital that this is undertaken without further delay. Aspects discussed include the control of RNA synthesis, the use of bacteriocins or enzybiotics (bacteriophages or purified lysins), the specific control of pathogenic clostridia, the design of new drugs affecting DNA synthesis in bacteria, the use of fecal-matter transplant strategies, the specific control of quorum sensing responses in bacteria, the use of new peptides as antibiotics and new ways to control bacteria that cause cancer, such as Helicobacter pylori cancers.

This volume brings together recent developments in quasispecies theory extended to variable environments and practical applications in elucidating viral dynamics and treatment designs. In particular, the existence of an error threshold in rugged fitness landscapes has opened the way to a new antiviral strategy termed lethal mutagenesis, which is now under intensive theoretical, experimental and clinical investigation. As such the book explains how an understanding of quasispecies dynamics within infected organisms has increased our knowledge of viral disease events. From a clinical perspective, population dynamics highlights important problems for viral disease control, such as the selection of drug-resistant mutants that often accompanies treatment failures, and suggests means of increasing the effectiveness of antiviral treatments. The book is intended for students and scientists interested in basic and applied aspects of biophysics, chemistry, biology, evolution and medical virology.

This book focuses on the function of antibodies in vivo. Recent years have seen an exponential growth in knowledge about the molecular and cellular mechanisms of antibody activity. These new results dramatically changed our view of how antibodies function in vivo. The importance of this class of molecules is demonstrated by the heightened susceptibility to infections of humans and mice with an altered capacity to generate pathogen specific antibody responses. Thus, the majority of our currently available vaccines, such as vaccines against influenza, measles and hepatitis focus on the generation of long lasting antibody responses. Recent evidence from a variety of in vivo model systems and from human patient cohorts has highlighted the exclusive role of cellular Fc-receptors for certain immunoglobulin isotypes and subclasses. With the recent discovery of a human Fc-receptor for IgM all different human immunoglobulin isotypes now have a cellular receptor, providing a feedback mechanism and link between antibodies and the cellular components of the immune system. Moreover it has become clear the complement and Fc-receptor system are tightly connected and regulate each other to ensure a well balanced immune response. Among the immunoglobulin isotypes IgG plays a very important protective role against microbial infections and also as a therapeutic agent to kill tumor cells or autoantibody producing B cells in autoimmune disease. Transfer of our knowledge about the crucial function of Fc-receptors has led to the production of a second generation of therapeutic antibodies with enhanced binding to this class of receptors. Binding of antibodies to Fc-receptors leads to the recruitment of the potent pro-inflammatory effector functions of cells from the innate immune system. Hence, Fc-receptors link the innate and adaptive immune system, emphasizing the importance of both arms of the immune system and their crosstalk during anti-microbial immune responses. Besides this pro-inflammatory activity immunoglobulin G (IgG) molecules are long known to also have an anti-inflammatory function. This is demonstrated by the use of high dose intravenous immunoglobulins as a therapeutic agent in many human autoimmune diseases. During the past five years several new insights into the molecular and cellular pathways of this anti-inflammatory activity were gained radically changing our view of IgG function in vivo. Several lines of evidence suggest that the sugar moiety attached to the IgG molecule is responsible for these opposing activities and may be seen as a molecular switch enabling the immune system to change IgG function from a pro- to an anti-inflammatory activity. There is convincing evidence in mice and humans that aberrant IgG glycosylation could be an important new pathway for understanding the impaired antibody activity during autoimmune disease. Besides this tremendous increase in basic knowledge about factors influencing immunoglobulin activity the book will also provide insights into how these new insights might help to generate novel therapeutic approaches to enhance IgG activity for tumor therapy on the one hand, and how to block the self-destructive activity of IgG autoantibodies during autoimmune disease on the other hand.

This volume details our current understanding of the architecture and signaling capabilities of known canonical and non-canonical inflammasome complexes and highlights their action, in particular in response to infection with important bacterial model organisms and the corresponding disease pathologies. The first chapters review new insights into the assembly and structures of inflammasome components and emphasize general strategies of up- and downstream signaling events. In addition, the authors specifically discuss the composition and activity of inflammasomes during infection with various gut pathogens (Salmonella, Shigella, Yersinia, Listeria and Helicobacter), respiratory pathogens (Mycobacterium, Legionella, Burkholderia and Streptococcus) as well as skin and soft tissue pathogens (Francisella and Staphylococcus). The discoveries presented provide a better understanding of the cellular and molecular biology of inflammasomes, which will pinpoint important new therapeutic targets for the treatment and prevention of multiple infectious diseases in the future. It is a valuable resource for students, scientists and clinicians, providing up-to-date information on this emerging research topic.

This book describes the molecular biology, pathogenesis, epidemiology, and potential strategies for control of chikungunya virus (CHIKV) infection. It offers insight into the structure and functions of CHIKV proteins as they relate to host response, interaction with the arthropod vector, and vaccination. A detailed account of both the epidemiological outlook and the clinical syndrome of CHIKV infection is provided. The complex host-virus interaction and the signaling pathways that mediate such interactions are also covered. Throughout the book, graphics and charts are used to provide stimulating discussion on important findings in the field of chikungunyalogy. The chapters are written with a global perspective by experts of CHIKV from around the world. This project is especially significant given that CHIKV is a pathogen of worldwide public health concern. Although the presence of CHIKV infection is not global yet, worldwide dissemination is predicted in the future due largely to the lack of effective treatment/therapy, efficient control of transmission, and knowledge about mechanisms of pathogenesis. Additionally, globalization of CHIKV is predicated on its mode of dissemination (mosquito vector) and cross border travel and migration.

How does it feel to confront a pandemic from the inside, one patient at a time? To bridge the gulf between a perilously unwell patient in quarantine and their distraught family outside? To be uncertain whether the protective equipment you wear fits the science or the size of the government stockpile? To strive your utmost to maintain your humanity even while barricaded behind visors and masks? Rachel is a palliative care doctor who looked after the most gravely unwell patients on the Covid-19 wards of her hospital. Amid the tensions, fatigue and rising death toll, she witnessed the courage of patients and NHS staff alike in conditions of unprecedented adversity. For all the bleakness and fear, she found that moments that could stop you in your tracks abounded. People who rose to their best, upon facing the worst, as a microbe laid waste to the population. Her new book, Breathtaking, is an unflinching insider's account of medicine in the time of coronavirus. Drawing on testimony from nursing, acute and intensive care colleagues - as well as, crucially, her patients - Clarke argue that this age of contagion has inspired a profound attentiveness to - and gratitude for - what matters most in life.

Traces the history of the study of tumor viruses and its role in driving breakthroughs in cancer research. Worldwide, approximately one-fifth of human cancers are caused by tumor viruses, with hepatitis B virus and HPV being the leading culprits. While the explosive growth in molecular biology in the late twentieth century is well known, the role that the study of tumor viruses has played in driving many of the greatest breakthroughs is not. Without the insights gained by studying tumor viruses, many significant theoretical advancements over the last four decades in cellular and molecular biology would not have been made. More practically, the study of tumor viruses has saved thousands, if not millions, of lives. In Cancer Virus Hunters, Gregory J. Morgan traces the high points in the development of tumor virology, from Peyton Rous's pioneering work on chicken tumors in 1909 to the successful development of an HPV vaccine for cervical cancer in 2006. Morgan offers a novel approach to understanding the interconnectedness of a long series of biomedical breakthroughs, including those that led to seven Nobel prizes. Among other advances, Morgan describes and contextualizes the science that prompted the discoveries of reverse transcriptase, RNA splicing, the tumor suppressor p53, the vaccine for hepatitis B, and the HIV test. He also explores how "cancer virus hunters" have demonstrated the virtue of beginning with a simple system, even when investigating a complex disease like cancer. Based on extensive archival research and over fifty interviews with experts, Cancer Virus Hunters is a tour de force summarizing a century of research to show how discoveries made with tumor viruses came to dominate the contemporary understanding of cancer. By showcasing the scientists themselves, the book makes for an unusually accessible journey through the history of science. It will be of interest to biomedical professionals-especially in oncology, hepatology, and infectious disease-in addition to historians of science and anyone interested in cancer research.

Head and neck squamous cell carcinoma (HNSCC), the sixth most prevalent cancer worldwide, remains a very difficult disease to treat and cure despite intensive investigation into molecular etiologies and tumor progression pathways. Due to public health efforts encouraging smoking cessation, the overall incidence of HNSCC has decreased in recent years in many countries. In contrast, the incidence of oropharyngeal squamous cell carcinoma (OPSCC) has increased significantly, and this subtype of HNSCC is commonly associated with human papillomavirus (HPV) infection. Moreover, individuals with HPV-positive OPSCC are generally younger and are frequently non-smokers, suggesting that HPV-associated OPSCC represents a distinct biologic entity. This volume summarizes the spectrum of current HPV-associated OPSCC research from the fundamental basic science to translational surgery and treatment approaches. Chapters are contributed by authoritative leaders in the fields of research and clinical care. Initial chapters address epidemiology, behavioral correlates of HPV infection, and racial disparities in oropharyngeal cancer. This is followed by chapters detailing HPV virology with focus on viral transformation, viral replication, and host response to viral infection. The molecular biology of HPV-associated OPSCC is investigated in chapters detailing alterations in signaling networks and unique mutational profiles of human tumors. Clinical presentation, surgical perspectives, and treatment paradigms specific to HPV-associated OPSCC conclude the volume. This comprehensive volume provides an up-to-date overview of both scientific discovery and clinical management of this emerging public health problem.

This volume presents a collection of reviews derived from work presented at the Aegean Conference: "5th Crossroads Between Innate and Adaptive Immunity". This meeting was the fifth in a series, and assembled a team of scientists working on mechanisms by which the innate immune system of the host senses pathogens, the cellular and signaling networks that orchestrate the innate response and antigen presentation and adaptive immunity. The importance of the crosstalk between innate immunity and the adaptive immune response has only recently started to be appreciated. Although it is well recognized that dendritic cells, NK cells, NK-T cells and T cells are all critical for the host response to pathogens, the respective fields that study the biology of these immune cells tend to exist in parallel worlds with minimum exchange of information and ideas. This fragmentation hinders the integration of these fields towards a unified theory of host response. The Aegean Conference "Crossroads between Innate and Adaptive Immunity" brought together leading international scientists and experts to address critical areas of Innate and Adaptive Immunity, a necessary step in the development of more efficient scientific exchange and crosspollination between these fields. This conference attracted scientists from all over the world to discuss their latest findings on the various aspects of Innate and Adaptive Immunity, and maximized scientific interchange through lecture presentations, poster sessions and informal discussions.
