Book excerpt: 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.
Download or read book Naturally Occurring Antibodies NAbs written by Hans U. Lutz and published by Springer Science & Business Media. This book was released on 2012-08-19 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Natural Antibodies in Health and Disease written by Ana Maria Hernandez and published by Frontiers Media SA. This book was released on 2018-02-01 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Characterization of Natural Autoantibodies A Case for Functional Significance written by Parvathi Ranganathan and published by . This book was released on 2010 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural autoantibodies are defined as self-reactive antibodies present in healthy individuals in the absence of purposeful immunization or any known antigenic stimulation. While most NAAbs are of the IgM isotype, T cell dependent isotypes such as IgG and IgA NAAbs have been reported. Natural antibodies are conserved through evolution; they have been detected in sharks and humans, the phylogenetic limits of vertebrates capable of producing antibodies. The phylogenetic conservation of NAAbs suggests that they play an important, but overlooked, role in the maintenance of physiological homeostasis of the immune system. My project involved the characterization of two NAAbs. The first part of my dissertation elucidates the production and functional characterization of an anti-T Cell Receptor NAAb, OR3. OR3 is an IgM heterohybridoma made from the peripheral blood B cells of a patient with Rheumatoid Arthritis. The results show that OR3 specifically binds to the Complementarity Determining Region 1 segment of TCRV b8 regions, is specific for a subset of T cells and blocks the antigen activation of these T cells. Importantly, OR3 does not induce apoptosis or necrosis of T cells. My results support our hypothesis that anti-TCR NAAbs are immunomodulatory and indicate that autoantibodies present in humans may have significant functional activity in the regulation of T cell responses. The second part of the dissertation describes the phenomenon of NAAbs to human delta opioid receptor. I affinity purified IgG antibodies to human DOR from intravenous immunoglobulin, a therapeutic blood product that contains purified IgG isolated from the plasma of thousands of healthy donors. The anti-DOR NAAbs bind to DOR protein, and initiate an activating signaling cascade, in a manner similar to a receptor specific agonist. Interestingly, there is a significant difference in the agonistic activity of the autoantibodies compared to the synthetic DOR agonist DPDPE. Unlike DPDPE, these autoantibodies display significant immunomodulatory activity as evinced by changes in CCR5 and CXCR4 chemokine receptor expression. The presence of functional autoantibodies in IVIG shows that they are a part of the normal healthy immune repertoire in humans. This work also presents data supporting the interconnecting network between the neuroendocrine and immune systems.

Download or read book Structure Physiology and Functions of Autoantibodies written by Neval Yurttutan Uyar and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prevalence of autoimmune diseases is increasing. Antibodies are responsible for the humoral type of adaptive immune responses, glycoprotein structure and produced by B lymphocytes. Failure of Immunologic self-tolerance due to environmental and genetic factors may predipose the development of autoimmunity. Self-antigens are either tolerogenic or ignored. Central tolerance occurs at immature T and B lymphocytes in the thymus and bone marrow. Peripheral tolerance occurs at mature lymphocytes encounter self-antigens in peripheral tissues. Negative selection, regulatory T cells, anergy, activation-induced cell death, immune suppression, receptor editing are examples of important steps of immune tolerance. B lymphocytes that produce antibodies which bind self-antigen with medium/low affinity escape from anergy and those antibodies are called as natural autoantibodies but the other ones with high affinity are undergo anergy, The natural antibodies have play critical roles as; discrimination foreign from self, auto-multireactivity, regulate the immunomodulation, maintain tissue homeostasis. Natural autoantibodies work as the templates for the production of pathogenic autoantibodies which has high affinity, switch the class and diverse somatically under proper conditions. Pathogenic autoantibodies can protect or cause diseases via neutralization of self-antigens, opsonization, antibody-dependent cellular cytotoxicity, activation of the complement system, pro-inflammatory and anti-inflammatory effect.
Download or read book Physiologic Autoimmunity and Preventive Medicine written by Alexander B. Poletaev and published by Bentham Science Publishers. This book was released on 2013-06-03 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This issue of Current Topics in Microbiology and Immunology records the proceedings of a Workshop on the Immunology of Sili cones held at the Natcher Conference Center, National Institutes of Health, Bethesda, Maryland, March 13 and 14, 1995. A large num ber of investigators from North America and Europe met to discuss available data on how the immune system responds to silicones and related materials. Some aspects of this field are controversial. Nonetheless, the meeting was marked by a civil and open ex change of scientific information and divergent interpretations, re flecting the traditions of scientific communication. Each invited participant was asked to submit an article sum marizing his/her presentation. Most of the papers are published as submitted, with only editorial changes to conform with the guide lines given to each contributor or revisions to clarify aspects of the paper. The papers should not be regarded as peer-reviewed publi cations. This preface will attempt to outline some of the immu nological areas of investigation relating to silicones.
