Carlotti E, Palumbo GA, Oldani E, et al. FCgammar IIIA and Fcgammar IIA polymorphisms do not predict clinical outcome of follicular non-Hodgkin's lymphoma patients treated with sequential CHOP and rituximab. Haematologica.
Natural killer (NK) cells are granular lymphocytes that play important roles in immunity against viruses and in the immune surveillance of tumors.
This review summarizes the structural findings that formed the basis of modern antibody–Fc receptor biology and recent advances of shared Fc receptor recognition by innate pentraxins.
Immunoglobulins are a group of closely related glycoproteins composed of 82 to 96% protein and 4 to 18% carbohydrate.
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 ...
Diversity of antigen-binding specificity may be considered the hallmark of antibodies; however, the human IgG-Fc region also exhibits binding specificity for multiple ligands.
The antibody Fc region is posttranslationally modified by N-linked glycosylation.
Antibody-dependent cellular cytotoxicity (ADCC), also called antibody-dependent cell-mediated cytotoxicity, is an immune mechanism through which Fc receptor-bearing effector cells can recognize and kill antibody-coated target cells ...
Antibody Fc: Chapter 8. FcγRs Across Species
Deleterious immune reactivity associated with FcR engagement, including immune complex diseases, allergic reactions due to IgE-mediated activation of mast cells and basophils, or facilitation of microbial infectivity, such as antibody ...
The key roles of the complement cascade and cellular Fcγ receptors in the innate and adaptive immune system are well documented.
This review summarizes these data and explains how this information might be used to better understand human autoimmune diseases and to develop novel therapeutic strategies.
This chapter reviews the literature of ADE in relation to the innate immune responses to Fcγ receptor ligation by infectious IgG immune complexes and discusses the research frontiers regarding this harmful antibody activity.
Fcγ receptors (FcγR) mediate many effector functions of antibody and are critical for defense against pathogens, including bacteria, viruses, and parasites.
Monoclonal antibodies (mAbs), including rituximab, are now a mainstay in the therapy of cancer.
Because of the ever-increasing number of pathogenic organisms and their rapid mutation rates, the humoral immune system must have the ability to adapt and change along with evolving pathogens.
This chapter offers an overview of the basic biology of phagocytes, macrophages, dendritic cells, and neutrophils and how it is affected by receptors for the Fc portion of antibodies (FcRs), particularly FcγRs.
Immunoglobulins (Igs, antibodies) are key players in adaptive immunity, and pathways mediated through the effector Fc portion of Ig are instrumental in controlling bacterial infections.
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.
