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.

Book excerpt: Antibody Fc is the first single text to synthesize the literature on the mechanisms underlying the dramatic variability of antibodies to influence the immune response. The book demonstrates the importance of the Fc domain, including protective mechanisms, effector cell types, genetic data, and variability in Fc domain function. This volume is a critical single-source reference for researchers in vaccine discovery, immunologists, microbiologists, oncologists and protein engineers as well as graduate students in immunology and vaccinology. Antibodies represent the correlate of protection for numerous vaccines and are the most rapidly growing class of drugs, with applications ranging from cancer and infectious disease to autoimmunity. Researchers have long understood the variable domain of antibodies, which are responsible for antigen recognition, and can provide protection by blocking the function of their target antigen. However, recent developments in our understanding of the protection mediated by antibodies have highlighted the critical nature of the antibody constant, or Fc domain, in the biological activity of antibodies. The Fc domain allows antibodies to link the adaptive and innate immune systems, providing specificity to a wide range of innate effector cells. In addition, they provide a feedback loop to regulate the character of the immune response via interactions with B cells and antigen-presenting cells. - Clarifies the different mechanisms of IgG activity at the level of the different model systems used, including human genetic, mouse, and in vitro - Covers the role of antibodies in cancer, infectious disease, and autoimmunity and in the setting of monoclonal antibody therapy as well as naturally raised antibodies - Color illustrations enhance explanations of the immune system

Available in PDF, EPUB and Kindle. Book excerpt: IgG antibodies are highly potent molecules, with the unique ability to link foreign particles to innate immune cells. IgG antibodies recognize antigens with high affinity and bind cellular Fc receptors with low affinity individually. These interactions occur in the form of immune complexes, resulting in high-avidity interactions. In fact, the effector functions triggered by IgG antibodies are highly dependent on the type of Fc receptor that is bound; however, many aspects can influence Fc receptor binding by IgG antibodies, including the IgG isotype and the composition of the glycan on the IgG antibody. Further, FcγR expression is not stagnant but instead is affected by the inflammatory milieu. These considerations, and others that affect targeting of IgG Fcs to specific FcγRs to elicit desired effector functions, are discussed herein.

This book was released on 2023-09-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fc receptor is a protein which is present on the surface of cells such as macrophages, B lymphocytes, mast cells, neutrophils, basophils and human platelets. Fc receptors allow the cells to connect with antibodies which are attached to the microbe's surface, and help the cells in identifying and eliminating the pathogens. Antibodies (Ab) protect against infectious agents by binding to pathogens and preventing their entry into target cells. They also facilitate the recruitment of Fc-receptor bearing cells that can eliminate pathogens or infected cells by mediating phagocytosis or cytotoxic activity known as Fc-mediated functions. Antibodies can be classified as neutralizing (nAb) antibodies and non-neutralizing (non-nAb) antibodies. Neutralizing (nAb) antibodies can mediate both functions and non-neutralizing (non-nAb) antibodies are limited to Fc-mediated functions. Non-nAb plays an important role in providing protection against a variety of viral infections, including smallpox, sindbis, yellow fever, ebola, and influenza. It also provides protection from non-viral infections such as tuberculosis and malaria. This book provides comprehensive insights on Fc receptors and their antibodies, as well as their role in disease and immunotherapy. It will serve as a reference to a broad spectrum of readers.

Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes recent advances in antibody glycosylation research. Covering major topics relevant for immunoglobulin glycosylation - analytical methods, biosynthesis and regulation, modulation of effector functions - it provides new perspectives for research and development in the field of therapeutic antibodies, biomarkers, vaccinations, and immunotherapy. Glycans attached to both variable and constant regions of antibodies are known to affect the antibody conformation, stability, and effector functions. Although it focuses on immunoglobulin G (IgG), the most explored antibody in this context, and unravels the natural phenomena resulting from the mixture of IgG glycovariants present in the human body, the book also discusses other classes of human immunoglobulins, as well as immunoglobulins produced in other species and production systems. Further, it reviews the glycoanalytical methods applied to antibodies and addresses a range of less commonly explored topics, such as automatization and bioinformatics aspects of high-throughput antibody glycosylation analysis. Lastly, the book highlights application areas ranging from the ones already benefitting from antibody glycoengineering (such as monoclonal antibody production), to those still in the research stages (such as exploration of antibody glycosylation as a clinical or biological age biomarker), and the potential use of antibody glycosylation in the optimization of vaccine production and immunization protocols. Summarizing the current knowledge on the broad topic of antibody glycosylation and its therapeutic and biomarker potential, this book will appeal to a wide biomedical readership in academia and industry alike.

Available in PDF, EPUB and Kindle. Book excerpt: Fc receptors provide an interface between humoral immunity and cellular immunity by binding to the Fc portion of immunoglobulin and mediating effector functions. Cells expressing Fc receptors play a major role in immune complex clearance via phagocytosis, leading to a context dependent pro- or anti-inflammatory environment. Signaling by multi-chain Fc receptor complexes, including Fc[gamma]RI, Fc[gamma]RIII, Fc[epsilon]RI and Fc[alpha]RI is mediated by the ITAM-containing common Fc[epsilon]RI[gamma] ([gamma]-chain) subunit. However, despite the use of a common [gamma]-chain, different Fc receptor complexes elicit specific cellular programs, suggesting additional layers of regulation of tyrosine based signaling by [alpha]-chain. We hypothesized that the unique [alpha]-chain cytoplasmic domains differentially modulate Fc receptor complex functions. In order to test our hypothesis, we established P388D1 and RBL-2H3 cell lines stably expressing either WT or Tail minus (TL) mutant Fc[gamma]RI [alpha]-chains. Data from these systems suggest that [alpha]-chain cytoplasmic domain (CY) indeed influences certain Fc receptor signaling pathways such as phagocytosis, degranulation and IL-6 production, but not others such as TNF-[alpha] and IL-1[beta] production. Furthermore, serine and threonine residues in the [gamma]-chain are reportedly phosphorylated after Fc receptor stimulation. We hypothesized that putative phosphorylation of serine/threonine sites fine-tune Fc receptor signaling, and provide the additional layer of regulation. To test this hypothesis, we stably transfected WT human [gamma]-chain or mutants carrying serine/threonine to alanine changes into RBL-2H3 cells lacking the endogenous [gamma]-chain expression. Using these cells, we observed that serine/threonine residues in the [gamma]-chain ITAM influence [gamma]-chain signaling pathways such as IL-4 production and intracellular calcium flux. Additionally, using mass spectrometry, we observed that Serine 51 in the ITAM is phosphorylated in stimulated samples. Studies with Serine 51 to Alanine and Aspartic Acid mutants suggest an inhibitory role for Serine 51 phosphorylation in [gamma]-chain signaling. Taken together, our data identified two layers of regulation of signaling by Fc receptors that utilizethe common [gamma]-chain. Identification of these regulators and, more importantly, identification of their interacting proteins, will provide attractive therapeutic targets for pharmacological interventions in Fc receptor mediated diseases.

Available in PDF, EPUB and Kindle. Book excerpt: It has only been a short time since the existence of suppressor cells was demonstrated, yet in this period of time a great deal of information has been compiled concerning their basic science and their functions or disordered functions in human disease. This volume is an tempt to clarify the immune mechanisms through which these cells act, their normal functions, and how their functions are disordered in certain disease states. In this volume some rational approaches are proposed to therapy of diseases perceived at least partially due to disordered immune regulation. Particular focus is on the recently emerging field of soluble suppressor factors as a means of providing adoptive immunotherapy in certain situations. I hope that future work in this field will justify the confidence in this approach.
