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 Inflammation and Atherosclerosis written by Georg Wick and published by Springer Science & Business Media. This book was released on 2011-12-03 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been known for over 150 years that hallmarks of inflammation can be observed in the wall of atherosclerotic vessels. It was, however, not clear if this inflammation is the cause or the consequence of atherogenesis. More recently, it has become evident that inflammation mediated both by innate and adaptive immunity is instrumental even in the earliest stages of the development of atherosclerotic lesions, i.e., that it plays an important pathogenetic role. In this volume, international experts in the field discuss the pathogenetic, diagnostic, preventive and possible therapeutic relevance of inflammation in atherogenesis. This book is intended for researchers and physicians in the fields of vascular biology, immunology and atherosclerosis.

Download or read book Molecular and Cellular Mechanisms of Antibody Activity written by Falk Nimmerjahn and published by Springer Science & Business Media. This book was released on 2013-05-22 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the function of antibodies in vivo. Recent years have seen an exponential growth in knowledge about the molecular and cellular mechanisms of antibody activity. These new results dramatically changed our view of how antibodies function in vivo. The importance of this class of molecules is demonstrated by the heightened susceptibility to infections of humans and mice with an altered capacity to generate pathogen specific antibody responses. Thus, the majority of our currently available vaccines, such as vaccines against influenza, measles and hepatitis focus on the generation of long lasting antibody responses. Recent evidence from a variety of in vivo model systems and from human patient cohorts has highlighted the exclusive role of cellular Fc-receptors for certain immunoglobulin isotypes and subclasses. With the recent discovery of a human Fc-receptor for IgM all different human immunoglobulin isotypes now have a cellular receptor, providing a feedback mechanism and link between antibodies and the cellular components of the immune system. Moreover it has become clear the complement and Fc-receptor system are tightly connected and regulate each other to ensure a well balanced immune response. Among the immunoglobulin isotypes IgG plays a very important protective role against microbial infections and also as a therapeutic agent to kill tumor cells or autoantibody producing B cells in autoimmune disease. Transfer of our knowledge about the crucial function of Fc-receptors has led to the production of a second generation of therapeutic antibodies with enhanced binding to this class of receptors. Binding of antibodies to Fc-receptors leads to the recruitment of the potent pro-inflammatory effector functions of cells from the innate immune system. Hence, Fc-receptors link the innate and adaptive immune system, emphasizing the importance of both arms of the immune system and their crosstalk during anti-microbial immune responses. Besides this pro-inflammatory activity immunoglobulin G (IgG) molecules are long known to also have an anti-inflammatory function. This is demonstrated by the use of high dose intravenous immunoglobulins as a therapeutic agent in many human autoimmune diseases. During the past five years several new insights into the molecular and cellular pathways of this anti-inflammatory activity were gained radically changing our view of IgG function in vivo. Several lines of evidence suggest that the sugar moiety attached to the IgG molecule is responsible for these opposing activities and may be seen as a molecular switch enabling the immune system to change IgG function from a pro- to an anti-inflammatory activity. There is convincing evidence in mice and humans that aberrant IgG glycosylation could be an important new pathway for understanding the impaired antibody activity during autoimmune disease. Besides this tremendous increase in basic knowledge about factors influencing immunoglobulin activity the book will also provide insights into how these new insights might help to generate novel therapeutic approaches to enhance IgG activity for tumor therapy on the one hand, and how to block the self-destructive activity of IgG autoantibodies during autoimmune disease on the other hand.

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 Current Challenges in Complement Diagnostics written by Erik J.M. Toonen and published by Frontiers Media SA. This book was released on 2023-12-14 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complement system is an important innate immune surveillance network that has a key role in protecting our bodies against pathogens and other threats. It is a highly complex system consisting of approximately 50 soluble and cell surface-bound proteins that interact to eliminate danger signals. These signals include factors such as invading microorganisms, necrotic cells, and immune complexes. Furthermore, complement can link innate and adaptive immune responses by regulating T cell and B cell responses. The complement system is tightly regulated to avoid uncontrolled activation. Dysregulation of the complement system has been linked to numerous diseases, both rare and common. Uncontrolled or exaggerated activation can lead to life-threatening conditions such as dysregulation of coagulation, fibrinolysis, systemic inflammation and shock, and possible failure of a variety of organs such as the eyes, kidneys, skin, brain, and vascular system. In recent years, the complement system has gained increased interest, especially as a promising candidate for therapeutic intervention. Eculizumab, the first approved complement inhibitor, is highly effective for treating atypical hemolytic uremic syndrome (aHUS) and paroxysmal nocturnal hemoglobinuria (PNH). Many more drug candidates are currently evaluated in ongoing clinical trials.

Download or read book Damage Associated Molecular Patterns in Human Diseases written by Walter Gottlieb Land and published by Springer. This book was released on 2018-10-09 with total page 893 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents current understanding of the importance of modern immunology in the etiopathogenesis of human diseases and explores how this understanding is impacting on diagnosis, prognosis, treatment, and prophylaxis. As the core of modern immunology, the “danger/injury model” is introduced and addressed throughout the book. Volume I of the book describes the network of damage-associated molecular pattern molecules (DAMPs) and examines the central role of DAMPs in cellular stress responses and associated regulated cell death, the promotion and resolution of inflammation, the activation of innate lymphoid cells and unconventional T cells, the stimulation of adaptive immunity, and tissue repair. The significance of DAMPs in a wide range of human diseases will then be explored in Volume II of the book, with discussion of the implications of injury-induced innate immunity for present and future treatments. This book is written for professionals from all medical and paramedical disciplines who are interested in the introduction of innovative data from immunity and inflammation research into clinical practice. The readership will include practitioners and clinicians such as hematologists, rheumatologists, traumatologists, oncologists, intensive care anesthetists, endocrinologists such as diabetologists, psychiatrists, neurologists, pharmacists, and transplantologists.

This Special Issue provides new insights into how MAPK signaling contributes to specific pathological processes across a range of conditions, including disorders of lung development, type 2 diabetes, proliferative skin diseases, cardiovascular diseases, and neurological diseases.

Download or read book The Evolution and Development of the Antibody Repertoire written by Harry W. Schroeder Jr. and published by Frontiers Media SA. This book was released on 2015-05-26 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although at first glance mechanisms used to create the variable domains of immunoglobulin appear to be designed to generate diversity at random, closer inspection reveals striking evolutionary constraints on the sequence and structure of these antigen receptors, suggesting that natural selection is operating to create a repertoire that anticipates or is biased towards recognition of specific antigenic properties. This Research Topics issue will be devoted to an examination of the evolution of antigen receptor sequence at the germline level, an evaluation of the repertoire in B cells from fish, pigs and human, an introduction into bioinformatics approaches to the evaluation and analysis of the repertoire as ascertained by high throughput sequencing, and a discussion of how study of the normal repertoire informs the construction or selection of in vitro antibodies for applied purposes.
