Human IgG Fc receptors

Clinical Immunology and Immunopathology, 1989
Considerable recent progress has been made in our understanding of how IgG immune complexes interact with plasma membrane Fc receptors (FcR) to mediate a diversity of biological responses in man. These responses include endocytosis of antibody complexes; stimulation of the secretion of various inflammatory mediators such as enzymes, oxygen products ...

The Unique Inhibitory IgG Receptor--FcγRIIb

Protein & Peptide Letters, 2018
FcγRIIb is the only inhibitory IgG receptor, which is divided into three subtypes of FcγRIIb1, FcγRIIb2 and FcγRIIb3. It is mainly responsible for the immune balance in vivo by cross-linking with the activated receptor to intracellular transduction inhibitory signals, and it plays an important biological role in the negative regulation of innate ...

Human Fc Receptors for IgG

International Reviews of Immunology, 1989
Human lymphocytes bear at least three different classes of Fc gamma R, which are different in cellular distribution, structure, and function. This review deals with recent advances in understanding the complexity of huFc gamma R. In particular, studies demonstrating the presence of alternate phosphatidyl inositol glycan-anchored and transmembrane ...

Human Lymphocytes with Receptors for IgG

International Archives of Allergy and Applied Immunology, 2009
Human lymphocytes with receptors for IgG (EA-RFC) were detected in peripheral blood by their ability to form rosettes with human erythrocytes sensitized with human (Ripley anti-CD) or rabbit IgG. EA-RFC were shown to be different from T-lymphocytes forming rosettes with sheep erythrocytes (E-RFC), both by direct studies of mixed rosette suspensions and

Fc receptor for IgG (FcR) on rat microglia

Journal of Neuroimmunology, 1994
Receptor for IgG (FcR) was demonstrated on rat microglia in vivo and in vitro by immunohistochemical staining with immune complexes of horseradish peroxidase (HRP) and rabbit IgG anti-HRP. Astrocytes, oligodendrocytes and neurons did not express FcR.

Demonstration of Cells with IgG Receptor in Human Placenta

Biology of the Neonate, 2009
The presence of two types of cells with IgG surface receptors was demonstrated in mature and immature human placentas. One type corresponded morphologically to the Hofbauer cells and the second to the blood monocytes. Transitional forms between monocytes and Hofbauer cells were also observed.

Structure and Function of Human and Murine Receptors for IgG

Annual Review of Immunology, 1988
The basic mechanisms by which phagocytes recognize foreign organisms have been known for more than 80 years. In 1903, Wright & Douglas (1) showed that human serum contains heat-stabile and heat-labile factors that bind to the bacteria and thus dramatically enhance the ability of blood phagocytes to ingest Staphylococcus.

Effect of Levamisole on the Human Monocyte IgG Receptor

The Journal of Immunology, 1977
Abstract Levamisole, an isomer of tetrahydro phenylimidazo thiazole, is a synthetic anti-helminthic which may have immunostimulating properties both in vivo and in vitro (1). Its mode of action is incompletely understood. There is evidence in murine systems that levamisole can increase the phagocytosis of heterologous cells by ...

IgG receptor polymorphisms: risk factors for disease

Immunogenetics, 1998
Two groups of receptors for immunoglobulin G (FcgammaR) can be distinguished. Endothelial cells and placental syncytiotrophoblasts express an MHC class I-like FcgammaR important for regulation of IgG half-life and IgG transport, respectively. FcgammaR expressed on leukocytes constitute a heterogeneous family of membrane bound and soluble proteins.
