Natural Autoantibodies provides an in-depth analysis of all aspects of natural antibodies. The book examines the advantages and pitfalls of every type of technique that is widely used for detecting autoantibodies. It also covers the sequencing of human autoantibody genes, discussing how sequencing is undertaken and the genetic clues available to elucidate the genetic origins of autoimmunity. Animal models of autoimmunity are also covered, and the up-to-date account provided in this book explains how natural autoantibodies have important regulatory functions and also occasionally serve as templates for autoimmunity. Other topics examined in Natural Autoantibodies: Their Physiological Role and Regulatory Significance include idiotypes of natural autoantibodies; the pathogenic role of natural autoantibodies; and methods to measure the effects of genetic and sex hormones, as well as aging, on natural autoantibodies. The book will be an excellent research tool and reference for immunologists, rheumatologists, and others interested in the topic.

This volume illustrates the functional properties of NAbs. Authors from pioneering groups report in their chapters on the tissue homeostatic, tissue regenerating and regulatory properties of NAbs and NAbs in pooled human IgG. Scientists interested in the regulation and modulation of components of the immune system found a whole variety of NAbs to cytokines with regulatory and protective functions and NAbs that modulate, e.g., dendritic cells, regulatory T cells, B cells and granulocytes. Considering the large plasma pools and initial difficulties in preparing IVIG that does not induce adverse effects upon infusion into recipients, this volume ends with a historical chapter on how pooled human plasma was fractionated and the IgG component pretreated for a safe intravenous application.

The Janeway's Immunobiology CD-ROM, Immunobiology Interactive, is included with each book, and can be purchased separately. It contains animations and videos with voiceover narration, as well as the figures from the text for presentation purposes.

Natural antibodies (NAbs) are found in normal individuals in the absence of exogenous antigenic stimulation. Natural antibodies rapidly recognize and protect against pathogens that have not been previously encountered. NAbs also cross-react with several self-antigens, which, besides their role as a first line of defense against pathogens, affords them the ability to perform important housekeeping functions in healthy organisms. Such housekeeping functions include the clearance of oxidized damaged structures and/or apoptotic cells, which prevents the induction of pro-inflammatory effects. In addition, NAbs play a role in preventing the expansion of specific auto-reactive clones, thereby behaving as regulatory elements in acute or chronic inflammation. To maintain the non-pathogenic balance between the dual pathogen/self-antigen cross-reactivities of NAbs, a strict regulation in NAb secretion and function is necessary to avoid autoimmune disease. Actually, some of the NAbs related auto-reactivities, such as anti-DNA and anti-MOG, have been associated with autoimmunity. Furthermore, NAbs have been shown to bind to ‘neo-self’ carbohydrate antigens on glycolipids and glycoproteins found on malignant but not normal cells, which suggests NAbs may take part in tumor immunosurveillance. Many aspects regarding NAbs have yet to be studied in more detail: the reactivity and function of NAbs in health and disease, the behavior of the NAb repertoire with increasing age, the regulation of natural antibody production and auto-reactivity, the ways to specifically activate NAbs producing cells with desired specificities, the characteristics of human NAbs, among others. This special topics eBook consists of a number of articles exploring the cells that produce NAbs as well as the characteristics, function, specificity, and/or the role of natural antibodies in health and disease.

Autoantibodies that are directed against self antigens are called autoantibodies. Not all autoantibodies are harmful. Autoantibodies can be useful in the removal of cell debris during inflammation. Some autoantibodies may be the actual pathogenic agents of autoimmune disease, the secondary consequences of tissue damage, or the harmless footprints of an etiologic agent. In this book, the authors present current research in the detection, pathogenicity and health implications of autoantibodies. Topics include the implicated autoantibodies in kidney disease and Alzheimer's disease; autoimmunity in cardiovascular disease; detection and analysis of natural autoantibodies; and B Cells and autoantibodies in multiple sclerosis.

Autoantibodies was published and presented in November 2006 at the International Congress of Autoimmunity in Sorrento, a small town in Campania, Italy. The Congress also celebrated the 100th anniversary of the first routine test for autoantibodies. An autoantibody is a type of antibody that is produced by the immune system and that fights one or more of a person’s own proteins. These autoantibodies cause autoimmune diseases such as lupus erythematosus. The authors and editors of this book provide a critical review of autoantibodies and their primary functions. They cite a number of major developments in the field of autoantibodies, including the detection of autoantibodies in which a healthy person is a carrier; the discovery that autoantibodies can be both pathogenic and protective in some cases; and the development of a device that will help monitor and detect a specific autoantibody using a small amount of serum and proteomic arrays. Aside from the pathogenic and protective autoantibodies, the book also discusses irrelevant autoantibodies, as these may be relevant for future research. It also addresses the importance of the autoantibodies in a person’s body. Clinical physicians, as well as scientists interested in the significance of autoantibodies in the human body, will find this book relevant. It will also be of interest to those who suffer from an autoimmune disease. * Incudes and exhaustive list of autoantibodies not covered by other publications * Short reviews can easily be checked for quick reference information * Both basic and clinical aspects are covered

Seventeen contributions address various topics that encompass facets of the blurred area where physiologic and autoimmunopathologic processes lose distinction. These processes remain intact during health but go haywire for multifactorial reasons, leading to the development of systemic autoimmune d
