This book discusses recent advances in our understanding of the role of oxidants in microbial pathophysiology, providing valuable insights into the complex role of reactive oxygen species (ROS) in host-microbial interactions. The various chapters take readers through the function of ROS in infections ranging from viral to bacterial, and describe how microorganisms have developed complex strategies to not only avoid contact with phagocyte-derived oxidants, but also protect themselves from injury when oxidants are encountered. Featuring the latest research in the field of microbial diseases, this timely book is a ready reference for scientists looking to develop new anti-microbial drugs.

Epstein-Barr virus (EBV) is a human gamma herpes virus that is best known for being the causative agent of infectious mononucleosis in man. A fascinating feature of this virus is its ability to persist in the host, and it is estimated that more than 95% of adults are carriers of the virus. Importantly, EBV can transform latently infected primary cells from healthy individuals into cancerous ones, thereby causing important human cancers such as B-cell neoplasms (e.g. Burkitt's lymphoma and Post-transplant lymphomas), certain forms of T-cell lymphoma, and some epithelial tumors (e.g. gastric carcinomas). Understanding viral latency, what triggers viral reactivation and the mechanism of transformation of normal host cells into malignant cells are critical for the development of strategies for the prevention and control of this intriguing virus and related cancers. In this book, expert EBV virologists comprehensively review this important subject from a genetic, biochemical, immunological, and cell biological perspective. Topics include: latent infections, EBV leader protein, EBNA-1 in viral DNA replication and persistence, EBNA-2 in transcription activation of viral and cellular genes, the nuclear antigen family 3 in regulation of cellular processes, molecular profiles of EBV latently infected cells, latent membrane protein 1 oncoprotein, regulation of latency by LMP2A, role of noncoding RNAs in EBV-induced cell growth and transformation, and the regulation of EBV latency by viral lytic proteins. This book is essential reading for all EBV virologists, as well as clinical and basic scientists working on oncogenic viruses.

The topic of this book, Collectins, is a family of proteins whose major function is in innate immunity, where Collectins act as pattern recognition receptors (PRRs). In general they recognize targets such as microbial surfaces and apoptotic cells, and once bound to a target, Collectins promote the clearance of microorganisms and damaged host tissue. New cell-surface proteins and glycoproteins, which act as Collectin receptors, are currently being identified. Some Collectins, particularly MBL, activate the complement system, which enhances the ability of antibodies to fight pathogens, via three MBL-associated proteases, the MASPs. Additionally, recent research has begun to show wider-ranging activities of Collectins, such as: * Their role in metabolism, and therefore their involvement in lifestyle diseases such as obesity and cardiovascular disease. * Their ability to modulate the adaptive immune response, as well as to recognize and trigger apoptosis of cancer cells, which makes them effective in the annihilation of cancer cells with multiple mutations. * The regulation of their expression by gonadal steroid hormones implicates them with critical roles in both male and female fertility. * Altered levels of Collectins have been associated with various autoimmune diseases. This book brings together current knowledge of the structure, functions and biological activities of Collectins, to describe their integral role in human health.

Childhood acute leukemias are one of the main causes of death in children aged 1 to 14 years in some countries; and unfortunately, we have been unable to prevent it. Certainly, a good parcel of it is due to the poor understanding about its etiology. This book aims to describe the most important theories and hypothesis regarding childhood acute leukemia. Written by the most outstanding researchers in the field, this book intends to contribute to a greater understanding of the etiology of this disease. It goes beyond the simple and common analysis of risk factors, which hardly allows us to draw definite conclusions. By addressing the etiology of the disease, discussing from molecular biology until epidemiology and clinical manifestations, this book will guide present and future approaches, contributing for a better clinical management of leukemia in children. The knowledge regarding etiology is a crucial step for a better evaluation, prevention and treatment of a disease. Thus, this book finally intends to provide such knowledge, allowing physicians and practitioners to a better manage of childhood acute leukemias.

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 volume discusses the interactions between viruses and their host cells, and explores the roles of host and viral genes and non-coding RNAs in the virus replication cycle. During infection, viruses express a variety of genes, encoding proteins and RNAs that serve to subjugate the cell - by redirecting cellular processes to support viral replication and, at the same time, by mitigating the cellular response to infection. In this book, experts discuss these interactions in depth, and elaborate on our current understanding of virus-cell interactions for a diverse range of viruses, including positive and negative sense RNA viruses, DNA viruses, and a vector-borne virus. The roles of non-coding RNAs are also discussed. While each class of viruses has distinct replication requirements, this volume reveals unique features and commonalities in viral replication cycles. Accordingly, it represents a valuable source of information for researchers and clinicians alike.

This volume presents a comprehensive overview of the latest developments in symbiosis research. It covers molecular, organellar, cellular, immunologic, genetic and evolutionary aspects of symbiotic interactions in humans and other model systems. The book also highlights new approaches to interdisciplinary research and therapeutic applications. Symbiosis refers to any mutually beneficial interaction between different organisms. The symbiotic origin of cellular organelles and the exchange of genetic material between hosts and their bacterial and viral symbionts have helped shaped the current diversity of life. Recently, symbiosis has gained a new level of recognition, due to the realization that all organisms function as a holobiome and that any kind of interference with the hosts influences their symbionts and vice versa, and can have profound consequences for the survival of both. For example, in humans, the microbiome, i.e., the entirety of all the microorganisms living in association with the intestines, oral cavity, urogenital system and skin, is partially inherited during pregnancy and influences the maturation and functioning of the human immune system, protects against pathogens and regulates metabolism. Symbionts also regulate cancer development, wound healing, tissue regeneration and stem cell function. The medical applications of this new realization are vast and largely uncharted. The composition and robustness of human symbionts could make them a valuable diagnostic tool for predicting impending diseases, and the manipulation of symbionts could yield new strategies for the treatment of incurable diseases.

Translational medicine addresses the gap between research and the clinical application of new discoveries. To efficiently deliver new drugs to care centers, a preclinical evaluation, both in vitro and in vivo, is required to ensure that the most active and least toxic compounds are selected as well as to predict clinical outcome. Antimicrobial nanomedicines have been shown to have higher specificity in their therapeutic targets and the ability to serve as adjuvants, increasing the effectiveness of pre-existing immune compounds. The design and development of new standardized protocols for evaluating antimicrobial nanomedicines is needed for both the industry and clinical laboratory. These protocols must aim to evaluate laboratory activity and present models of pharmacokinetic-pharmacodynamic and toxicokinetic behavior that predict absorption and distribution. Likewise, these protocols must follow a theranostics approach, be able to detect promising formulations, diagnose the infectious disease, and determine the correct treatment to implement a personalized therapeutic behavior. Given the possibilities that nanotechnology offers, not updating to new screening platforms is inadequate as it prevents the correct application of discoveries, increasing the effect of the valley of death between innovations and their use. This book is structured to discuss the fundamentals taken into account for the design of robust, reproducible and automatable evaluation platforms. These vital platforms should enable the discovery of new medicines with which to face antimicrobial resistance (RAM), one of the great problems of our time.

Immunologists, perhaps understandably, most often concentrate on the human immune system, an anthropocentric focus that has resulted in a dearth of information about the immune function of all other species within the animal kingdom. However, knowledge of animal immune function could help not only to better understand human immunology, but perhaps more importantly, it could help to treat and avoid the blights that affect animals, which consequently affect humans. Take for example the mass death of honeybees in recent years - their demise, resulting in much less pollination, poses a serious threat to numerous crops, and thus the food supply. There is a similar disappearance of frogs internationally, signaling ecological problems, among them fungal infections. This book aims to fill this void by describing and discussing what is known about non-human immunology. It covers various major animal phyla, its chapters organized in a progression from the simplest unicellular organisms to the most complex vertebrates, mammals. Chapters are written by experts, covering the latest findings and new research being conducted about each phylum. Edwin L. Cooper is a Distinguished Professor in the Laboratory of Comparative Immunology, Department of Neurobiology at UCLA's David Geffen School of Medicine.
