This book explains how the immune system functions, namely, how individual cells of the immune system make the decision to respond or not to respond to foreign microbes and molecules, and how the critical molecules function to trigger the cellular reactions in an all-or-none (quantal) manner. To date, there has not been a complete description of the immune system and its cells and molecules, primarily because most of the information has accumulated only in the last 40 years and our understanding has been expanding rapidly only in the last 20 years. It is now clear that the cells have evolved a way to ?count? the number of foreign antigenic molecular ?hits?, and they only react when a critical number of events have accumulated. Subsequently, control over the reaction is transferred to a systemic lymphocytotrophic hormone system that determines the tempo, magnitude and duration of the immune reaction. This book explains in detail how the immune system, cells and molecules work for the first time. With this understanding as a basis, the pathogenesis of autoimmunity can now be understood as a mutational usurpation of the genes encoding molecules that participate in a sensitive feedback regulatory control of the immune reaction. By comparison, malignant transformation is understood as a mutational usurpation of the genes encoding the molecules that control the quantal decision to proliferate, so that normal ligand/receptor cell growth control is circumvented. This molecular understanding of the immune system is especially important for the design of successful vaccines, and also explains why vaccines fail.

In the highly competitive world of biomedical science, often the rush to publish and to be recognized as "first" with a new discovery, concept or method, is lost in the hurly-burly of the moment, as "the maddening crowd" moves on to the next "new thing". One of the great things about immunology today is that it has only become mature as a science within the last half-century, and especially within the past 35 years as a consequence of the revolution of molecular immunology, which has taken place only since 1980. Consequently, most of those who have contributed to our new understanding of how the immune system functions are still alive and well, and still contributing. Thus, "A Living History of Immunology" collates many stories from the investigators who actually performed the experiments that have established the frontiers of immunology. Accordingly, this volume combats "revisionist science", by those who want to alter history by telling the stories a different way than actually happened. In this regard, one of the good things about science vs. other disciplines is that we have the written record of what was done, when it was done and by whom. Even so, we do not have the complete story or narrative of how and why experiments were done, and what made the differences that led to success. This volume captures and chronicles some of these stories from the past fifty years in immunology.

'Research on immunity has dramatically expanded in recent six decades, yielding exciting new information concerning the molecules and cells that initiate the multi-faceted processes combined under the term 'Molecular Immunity'. These processes are crucial for protection against invaders, but are also responsible for certain pathogenic conditions. Prof. Kendall Smith, a prominent contributor to this field, provides in this book, for the first time, the detailed history of thoughts and consequent achievements in the field of cellular immunology.'Dr Igal GeryScientist EmeritusNational Eye Institute, NIHThis book covers a scientific history of the discoveries in immunology of the past 60-years, i.e. what was discovered, who made the advances and how they accomplished them, and why others did not.All molecular advances occurred in the last 60 years, and no one has described them.

The immune system is a natural component, regulator and direct participant in the physiological activities in a healthy body. A considerable number of immune functions, including those related to antimicrobial defense, derive from autoclearance as well as construction and support of multicellularity. Various pathological processes in any organ are usually accompanied by different patterns of cell death and, thus, by increased exposure and presentation of self antigens. These events induce the secondary rise in production of autoantibodies with appropriate specificity (opsonins), which provides augmentation of clearance by facilitating the efficacy of macrophage-dependent consumption of debris in the affected organ. Secondary changes in production and serum content of autoantibodies can be considered the universal and earliest detectable marker of any chronic disease. Experimental and clinical production antibodies reveal antibodies against nuclear antigens, which penetrate into living cell nuclei and alter nuclear acid synthesis, cell proliferation and function. Autoantibodies can thus be regarded as hormone-like bioregulators of gene expression. The immune system is apparently able to reproduce complementary regulators for various cell receptors, including nuclear ones. The book focuses on physiological autoimmunity models and delves into the relation between autoimmunity and autoallergy in the context of disease prevention and prediction. The E-book is a unique and comprehensive monograph and includes a history and contemporary research on natural autoimmunity - a fundamental concept essential for many branches of medicine and pathology. The concepts described in this e-book also have broad practical implications for the healthcare sector, because it establishes effective method of early prediction for many different diseases and creates a basis for prophylaxis. The reference gives medical and clinical professionals a chance to revisit old dogmas and acquire fruitful perspectives for theoretical reasoning and research planning.

This book is a collection of excellent reviews and perspectives contributed by experts in the multidisciplinary field of basic science, clinical studies and treatment options for a wide range of acute and chronic inflammatory diseases or cancer. The goal has been to demonstrate that persistent or chronic (unresolved or subclinical) inflammation is a common denominator in the genesis, progression and manifestation of many illnesses and/or cancers, particularly during the aging process. Understanding the fundamental basis of shared and interrelated immunological features of unresolved inflammation in initiation and progression of chronic diseases or cancer are expected to hold real promises when the designs of cost-effective strategies are considered for diagnosis, prevention or treatment of a number of age-associated illnesses such as autoimmune and neurodegenerative diseases as well as many cancers.

Ever since Regulatory T cells (T-Regs) were first defined as peripheral CD4+ T cells that express the interleukin-2 (IL-2) receptor alpha chain (IL-2Ra), there have been intensive efforts to determine the molecular mechanisms whereby this minor subset of CD4+ T cells (~ 5-10%) nonspecifically suppresses all potential effector T cells, whether reactive to self or non-self antigens. Multiple possible molecular mechanisms have been implicated, including the scavenging of IL-2 via the expression of high densities of IL-2Rs, the inhibition of antigen presentation via CTLA-4 molecules leading to decreased IL-2 production, the activation of intracellular cAMP thereby suppressing both IL-2 production and action, and the production of suppressive cytokines such as IL-10 and Tumor Growth Factor-beta, to list a few. However, the field has thus far failed to come to a consensus, such that some investigators have now asserted that many molecular mechanisms may be operative, in fact that perhaps all of the described mechanisms may account for the suppressive effects of these cells, acting either simultaneously or sequentially. Thus, this Research Topic is focused on articles that can shed some new light on the molecular mechanisms responsible for T-Reg immunosuppression.

This book adds to a intensively investigated question of immunological research. How do regulatory T cells mediate their function to ensure tolerance against self-antigen? The author analyzes the interaction via the cytokine interleukin 2 between T helper cells, which mediate immune responses, and regulatory T cells. Since both cell types depend on interleukin 2 to mediate their functions, competition for interleukin 2 is likely. A mathematical model is developed to describe the interaction. This model focuses on the interleukin 2 receptor dynamics on helper and regulatory T cells and the extracellular interleukin 2 diffusion. The interleukin 2 receptor dynamics is governed mainly by an autocrine positive feedback loop on both cell types. However, its differential regulation results in a switch-like up-regulation of the receptors on T helper cells and a gradual adaptation of the receptor levels to extracellular interleukin 2 supply on regulatory T cells. This difference enables regulatory T cells to efficiently compete for interleukin 2 and deprive T helper cells of their growth factor. Cell culture experiments verify these findings. It can be shown that the antigen stimulus and the intercellular distance are relevant control parameters for competition. Other mechanisms are described for suppression of T helper cell action by regulatory T cells; competition for interleukin 2 may act in concert with them.
