Immunobiology of the Macrophage presents an account of the state of knowledge of the immunobiology of the macrophage. The book's contributors—immunologists of diverse scientific and geographic backgrounds—have been encouraged to give personal accounts of developments in their special fields of interest as well as critical surveys of the backgrounds leading to these developments. The book begins with a study on the functions of macrophages in the initiation and regulation of antibody responses in vitro. This is followed by separate chapters on topics such as the role of macrophages in making antigen more immunogenic and less tolerogenic; functional distinctions between macrophages at different sites; and the role of the macrophage in antigen recognition by T lymphocytes. Subsequent chapters examine interactions between macrophages and lymphocytes in the production of interferon and other mediators of cellular immunity; macrophage cell lines and their uses in immunobiology; and cytotoxic macrophages in allograft rejection.

Macrophages are core components of the innate immune system. Once activated, they may have either pro- or anti-inflammatory effects that include pathogen killing, safe disposal of apoptotic cells or tissue renewal. The activation state of macrophages is conceptualized by the so-called M1/M2 model of polarization. M2 macrophages are not simply antagonists of M1 macrophages; rather, they represent a network of tissue resident macrophages with roles in tissue development and organ homeostasis. M2 macrophages govern functions at the interfaces of immunity, tissue development and turnover, metabolism, and endocrine signaling. Dysfunction in M2 macrophages can ruin the healthy interplay between the immune system and metabolic processes, and lead to diseases such as insulin resistance, metabolic syndrome, and type 1 and 2 diabetes mellitus. Furthermore, M2 macrophages are essential for healthy tissue development and immunological self-tolerance. Worryingly, these functions of M2 macrophages can also be disrupted, resulting in tumor growth and autoimmunity. This book comprehensively discusses the biology of M2 macrophages, summarizes the current state of knowledge, and highlights key questions that remain unanswered.

The Macrophage, second edition provides a unique, comprehensive review of the current scientific knowledge of the multifaceted role of this important and intriguing cell in health and disease. In 16 chapters, written by experts in the field, it covers the basic biology and diverse functions of macrophages in specific diseases and the complex interactions between macrophages and other cells. Ranging from their role in the defence against pathogens, their role as hosts for pathogens (including HIV), their complex roles in diseases such as arthritis and cancer, and their potential for use in novel gene therapy approaches to disease treatment, the book gives an up to the minute account of active macrophage research.

The second edition of Avian Immunology provides an up-to-date overview of the current knowledge of avian immunology. From the ontogeny of the avian immune system to practical application in vaccinology, the book encompasses all aspects of innate and adaptive immunity in chickens. In addition, chapters are devoted to the immunology of other commercially important species such as turkeys and ducks, and to ecoimmunology summarizing the knowledge of immune responses in free-living birds often in relation to reproductive success. The book contains a detailed description of the avian innate immune system, encompassing the mucosal, enteric, respiratory and reproductive systems. The diseases and disorders it covers include immunodepressive diseases and immune evasion, autoimmune diseases, and tumors of the immune system. Practical aspects of vaccination are examined as well. Extensive appendices summarize resources for scientists including cell lines, inbred chicken lines, cytokines, chemokines, and monoclonal antibodies. The world-wide importance of poultry protein for the human diet, as well as the threat of avian influenza pandemics like H5N1 and heavy reliance on vaccination to protect commercial flocks makes this book a vital resource. This book provides crucial information not only for poultry health professionals and avian biologists, but also for comparative and veterinary immunologists, graduate students and veterinary students with an interest in avian immunology. - With contributions from 33 of the foremost international experts in the field, this book provides the most up-to-date review of avian immunology so far - Contains a detailed description of the avian innate immune system reviewing constitutive barriers, chemical and cellular responses; it includes a comprehensive review of avian Toll-like receptors - Contains a wide-ranging review of the "ecoimmunology" of free-living avian species, as applied to studies of population dynamics, and reviews methods and resources available for carrying out such research

Macrophages have unique and diverse functions necessary for survival. And, in humans (and other species), they are the most abundant leukocytes in tissues. The Innate functions of macrophages that are best known are their unusual ability to either “Kill” or “Repair”. Since killing is a destructive process and repair is a constructive process, it was stupefying how one cell could exhibit these 2 polar – opposite functions. However, in the late 1980’s, it was shown that macrophages have a unique ability to enzymatically metabolize Arginine to Nitric Oxide (NO, a gaseous non – specific killer molecule) or to Ornithine (a precursor of polyamines and collagen for repair). The dual Arginine metabolic capacity of macrophages provided a functional explanation for their ability to kill or repair. Macrophages predominantly producing NO are called M1 and those producing Ornithine are called M2. M1 and M2 – dominant responses occur in lower vertebrates, and in T cell deficient vertebrates being directly driven by Damage and Pathogen Associated Molecular Patterns (DAMP and PAMP). Thus, M1 and M2 are Innate responses that protect the host without Adaptive Immunity. In turn, M1/M2 is supplanting previous models in which T cells were necessary to “activate” or “alternatively activate” macrophages (the Th1/Th2 paradigm). M1 and M2 macrophages were named such because of the additional key findings that these macrophages stimulate Th1 and Th2 – like responses, respectively. So, in addition to their unique ability to kill or repair, macrophages also govern Adaptive Immunity. All of the foregoing would be less important if M1 or M2 – dominant responses were not observed in disease. But, they are. The best example to date is the predominance of M2 macrophages in human tumors where they act like wound repair macrophages and actively promote growth. More generally, humans have become M2 – dominant because sanitation, antibiotics and vaccines have lessened M1 responses. And, M2 dominance seems the cause of ever - increasing allergies in developed countries. Obesity represents a new and different circumstance. Surfeit energy (e.g., lipoproteins) causes monocytes to become M1 dominant in the vessel walls causing plaques. Because M1 or M2 dominant responses are clearly causative in many modern diseases, there is great potential in developing the means to selectively stimulate (or inhibit) either M1 or M2 responses to kill or repair, or to stimulate Th1 or Th2 responses, depending on the circumstance. The contributions here are meant to describe diseases of M1 or M2 dominance, and promising new methodologies to modulate the fungible metabolic machinery of macrophages for better health.

Immune Rebalancing: The Future of Immunosuppression summarizes the most promising perspectives of immunopharmacology, in particular in the area of immunosuppression by considering molecular pathways, personalized medicine, microbiome and nanomedicine. Modulation of immune responses for therapeutic purposes is a particularly relevant area, given the central role of anomalous immunity in diseases. These diseases vary from the most typically immune-related syndromes (autoimmune diseases, allergy and asthma, immunodeficiencies) to those in which altered immunity and inflammation define the pathological outcomes (chronic infections, tumours, chronic inflammatory and degenerative diseases, metabolic disorders, etc. - Visits immunosuppression from a modern point of view of signalling mechanisms at the light of the current knowledge of signalling mechanisms and regulatory networks allows the reader to formulate new ideas and concepts on how to use immunosuppression the therapeutic purposes - Encourages researchers to engage into exploring the field of pharmacological modulation of immune responses in depth, and with the new knowledge and tools available, designs more effective therapeutic strategies to autoimmune and inflammatory diseases, cancer, degenerative diseases and infections - Examines the link between molecular pathways associated to immune-suppression and the new immunopharmacology approaches - Provides information on the new strategies for drug development in this field - Considers the role of microbes in the development of the mammalian immune system and immune responses, which will widen the reader's strategy for addressing therapeutic immune modulations

During the past decade, the rapid growth of molecular and cellular knowledge of macrophages, as a specialized host defense and homeostatic system, has begun to offer attractive targets for therapeutic intervention. Macrophages play a central role in a wide range of disease processes, from genetically determined lysosomal storage diseases, to acute sepsis, chronic inflammation and repair, tissue injury and cell death. Under- or overactivity of macrophage clearance, immune effector functions and responses to metabolic abnormalities contribute to common disorders such as autoimmunity, atherosclerosis, Alzheimer’s disease and major infections including AIDS and Tuberculosis. Whilst the goals of therapeutic intervention based on improved understanding of macrophage functions and their contribution to pathogenesis may seem self evident, there are considerable difficulties in producing useful new agents. The present volume covers a range of subjects and provides opportunities for a more focused macrophage-targeted approach. The individual chapters review selected topics briefly, to place cellular processes and molecular targets in perspective. Overall, the volume should provide a broad sample of the state of the art. Useful reviews and references in the literature are cited within individual chapters.
