Infection with the human immunodeficiency virus is characterized by the destruction of the host immune system as also reflected by a progressive loss of CD4-positive T-cells. This finally results in the host's incapacity to deal with opportunistic infections and the immune surveillance of tumors, a clinical status known as the Acquired Immunodeficiency Syndrome (AIDS). The book AIDS Pathogenesis provides the reader with a complete overview of the clinical course of HIV-1 infection. It describes the clinical aspects of primary infection, the different clinical outcomes of HIV-1 infection, and strategies for anti-viral treatment. In addition, more fundamental aspects of HIV-1 infection are reviewed. These include the biology of the virus and the novel insights in AIDS pathogenesis. Not only is the significance of an HIV-specific cellular and humoral immune response discussed, but also the possible incapacity of the adult human host to deal with T-cell destruction. Finally, the book discusses the currently used laboratory markers that allow for monitoring of the clinical course of infection.
“About 25 years ago, Mosmann & Coffman introduced the TH1 / TH2 paradigm of T helper cell differentiation which helped explain many aspects of adaptive immunity from eliminating intracellular versus extracellular pathogens to induction of different types of tissue inflammation. However, TH1 / TH2 paradigm could not adequately explain development of certain inflammatory responses which provided impetus for the discovery of a new subset of T cells called TH17 cells. After the discovery of differentiation and transcription factors for TH17 cells, it was clear that TH17 cells represent an independent subset of T cells with specific functions in eliminating certain extracellular pathogens, presumably not adequately handled by TH1 or TH2 cells. The major role of TH17 cells has been described in inducing auto-immune tissue inflammation. The discovery of TH17 cells has expanded the TH1 / TH2 paradigm, and the integration of TH17 cells with TH1 and TH2 effector T cells is beginning to explain the underlying mechanisms of tissue inflammation in a number of infections and auto-immune disease settings.” - From Chapter One by Vijay K. Kuchroo, Harvard University, USA “The recently identified Interleukin 17 (IL-17) cytokine family contributes to immunity to infectious diseases and chronic inflammatory diseases. Further studies on the regulation and function of this important cytokine family may provide better understanding on the roles of the IL-17 family in immune-mediated diseases; such knowledge may lead to the development of immunotherapeutic strategies for treatment of several inflammatory diseases.” - From Chapter Two by Chen Dong, University of Texas and MD Anderson Cancer Center, USA
Methods in Toxicology, Volume 2: Mitochondrial Dysfunction provides a source of methods, techniques, and experimental approaches for studying the role of abnormal mitochondrial function in cell injury. The book discusses the methods for the preparation and basic functional assessment of mitochondria from liver, kidney, muscle, and brain; the methods for assessing mitochondrial dysfunction in vivo and in intact organs; and the structural aspects of mitochondrial dysfunction are addressed. The text also describes chemical detoxification and metabolism as well as specific metabolic reactions that are especially important targets or indicators of damage. The methods for measurement of alterations in fatty acid and phospholipid metabolism and for the analysis and manipulation of oxidative injury and antioxidant systems are also considered. The book further tackles additional methods on mitochondrial energetics and transport processes; approaches for assessing impaired function of mitochondria; and genetic and developmental aspects of mitochondrial disease and toxicology. The text also looks into mitochondrial DNA synthesis, covalent binding to mitochondrial DNA, DNA repair, and mitochondrial dysfunction in the context of developing individuals and cellular differentiation. Microbiologists, toxicologists, biochemists, and molecular pharmacologists will find the book invaluable.

It then moves on to discuss the immunobiology mechanisms that influence graft-versus-host disease (GVHD), graft-versus-leukemia effect, and transplantation success. Using illustrative figures, highlighting key issues, describing recent successes, and discussing unanswered questions, this book sums up the current state of HSCT to enhance the prospects for the future. The second edition is fully revised and includes new chapters on microbiome, metabolism, kinase targets, micro-RNA and mRNA regulatory mechanisms, signaling pathways in GVHD, innate lymphoid system development, recovery and function in GVHD, genetically engineered T-cell therapies, immune system engagers for GVHD and graft-versus-tumor, and hematopoietic cell transplant for tolerance induction in solid organ grafts. - Brings together perspectives from leading laboratories and clinical research groups to highlight advances from bench to the bedside - Guides readers through the caveats that must be considered when drawing conclusions from studies with animal models before correlating to clinical allogeneic hematopoietic stem cell transplantation (HSCT) scenarios - Categorizes the published advances in various aspects of immune biology of allogeneic HSCT to illustrate opportunities for clinical applications
The Mosaic of Autoimmunity: The Novel Factors of Autoimmune Diseases describes the multifactorial origin and diversity of expression of autoimmune diseases in humans. The term implies that different combinations of factors in autoimmunity produce varying and unique clinical pictures in a wide spectrum of autoimmune diseases. Most of the factors involved in autoimmunity can be categorized into four groups: genetic, immune defects, hormonal and environmental factors. In this book, the environmental factors are reviewed, including infectious agents, vaccines as triggers of autoimmunity, smoking and its relationship with rheumatoid arthritis, systemic lupus erythematosus, thyroid disease, multiple sclerosis and inflammatory bowel diseases. An entirely new syndrome, the autoimmune/inflammatory syndrome induced by adjuvants (ASIA), is also included, along with other diseases that are now recognized as having an autoimmune etiopathogenesis.
A translational overview of neuroimmune diseases for neuroscientists and clinicians that clarifies the pathological mechanisms underlying neuroimmune diseases and builds a comprehensive bridge between the latest research findings and their clinical implications in daily practice. The material is presented in two steps. The first section comprises a review of the pathogenic actions of immune cells in brain diseases. Here the authors discuss the mechanisms through which immune cells disrupt the functions of nerve cells. The second section explores the ways in which the brain becomes dysfunctional due to impaired nerve cell function. Based on pathogenesis, diagnostic and therapeutic strategies are discussed for each clinical category. The book will be invaluable for use in clinical practice of neuroimmune diseases
“Infogest” (Improving Health Properties of Food by Sharing our Knowledge on the Digestive Process) is an EU COST action/network in the domain of Food and Agriculture that will last for 4 years from April 4, 2011. Infogest aims at building an open international network of institutes undertaking multidisciplinary basic research on food digestion gathering scientists from different origins (food scientists, gut physiologists, nutritionists...). The network gathers 70 partners from academia, corresponding to a total of 29 countries. The three main scientific goals are: Identify the beneficial food components released in the gut during digestion; Support the effect of beneficial food components on human health; Promote harmonization of currently used digestion models Infogest meetings highlighted the need for a publication that would provide researchers with an insight into the advantages and disadvantages associated with the use of respective in vitro and ex vivo assays to evaluate the effects of foods and food bioactives on health. Such assays are particularly important in situations where a large number of foods/bioactives need to be screened rapidly and in a cost effective manner in order to ultimately identify lead foods/bioactives that can be the subject of in vivo assays. The book is an asset to researchers wishing to study the health benefits of their foods and food bioactives of interest and highlights which in vitro/ex vivo assays are of greatest relevance to their goals, what sort of outputs/data can be generated and, as noted above, highlight the strengths and weaknesses of the various assays. It is also an important resource for undergraduate students in the ‘food and health’ arena.
A comprehensive text providing much of the currently available knowledge in the field of cytokines.

Part III (Diagnosis and Treatment) covers the histologic, muscle enzyme histochemical, electron microscopic, and resin histology features of PM/DM along with those electromyographic features that could help make a more accurate diagnosis. Part IV (Overview) summarizes the issues that may not have been clear and highlights differing and unsettled views or present available data. This text is directed to clinicians in private practice or in academic institutions concerned with PM/DM patients, including neurologists, rheumatologists, pediatricians, dermatologists, physiatrists, and neuromuscular investigators. This book is intended as well for neuromuscular pathologists who interpret muscle biopsy specimens and electromyographers who perform EMG studies to help determine the clinical diagnosis. Researchers in immunology and immunopathology of neuromuscular diseases will find discussions in this book invaluable.
The structure, functions, and interactions of myeloid cells have long been the focus of research and therapeutics development. Yet, much more remains to be discovered about the complex web of relationships that makes up the immune systems of animals. Scientists today are applying genome-wide analyses, single-cell methods, gene editing, and modern imaging techniques to reveal new subclasses of differentiated myeloid cells, new receptors and cytokines, and important interactions among immune cells. In Myeloid Cells in Health and Disease: A Synthesis, Editor Siamon Gordon has assembled an international team of esteemed scientists to provide their perspectives of myeloid cells during innate and adaptive immunity. The book begins by presenting the foundational research of Paul Ehrlich, Elie Metchnikoff, and Donald Metcalf. The following chapters discuss evolution and the life cycles of myeloid cells; specific types of differentiated myeloid cells, including macrophage differentiation; and antigen processing and presentation. The rest of the book is organized by broad topics in immunology, including the recruitment of myeloid and other immune cells following microbial infection the role of myeloid cells in the inflammation process and the repair of damaged tissue the vast arsenal of myeloid cell secretory molecules, including metalloproteinases, tumor necrosis factor, histamine, and perforin receptors and downstream signaling pathways that are activated following ligand-receptor binding roles of myeloid cells during microbial and parasite infections contributions of myeloid cells in atherosclerosis myeloid-derived suppressor cells in tumor development and cancer Myeloid Cells in Health and Disease: A Synthesis will benefit graduate students and researchers in immunology, hematology, microbial pathogenesis, infectious disease, pathology, and pharmacology.
