Phagocyte Fc receptors for IgG

1998
This chapter focuses on the Fc receptors for IgG (FcγR) on phagocytic cells, e.g. polymorphonuclear neutrophils (PMNs), monocytes and macrophages. Eosinophils and basophils/mast cells which also have phagocytic properties are not discussed. PMNs and monocytes circulate in the bloodstream and are derived from pluripotent haematopoietic stem cells in the

IgG Fc Receptors: Evolutionary Considerations

2019
Immunoglobulins (Ig), a critical component of the adaptive immune system, are present in all jawed vertebrates and through sophisticated diversification mechanisms are able to recognize antigens of almost infinite diversity. During mammalian evolution, IgG has emerged as the predominant Ig isotype that is elicited upon antigenic challenge, representing

Cytotoxicity mediated by human Fc receptors for IgG

Immunology Today, 1989
The Fc receptors for IgG(Fc gamma R) play a major role in the removal of antibody-coated infectious agents and may be important molecules for triggering cytotoxicity of tumor cells; they may also serve as an entry for infection of Fc gamma R-bearing cells by viral (including HIV and Dengue), and perhaps other infectious agents.

IgG receptors on foetal chick yolk sac

Journal of Cell Science, 1978
ABSTRACT In the chicken, maternal IgG is deposited in the oocyte yolk and subsequently transported intact by the foetal chick yolk sac into the chick circulation. Such transport appears to require a specific membrane-localized IgG receptor.

Studies on the chicken lymphocyte receptor for aggregated IGG

Developmental & Comparative Immunology, 1982
Chicken lymphocytes isolated from different lymphoid organs were analyzed for Fc IgG receptor by binding of heat aggregated IgG (agg IgG) in the indirect immunofluorescence test. The binding of agg IgG was shown to be specific for Fc IgG receptor, since IgM and F(ab')2 fractions were bound to the lymphocytes in a much less degree. The highest frequency

[Significance of Fc receptors for IgG].

Allergie und Immunologie, 1987
Fc gamma R are glycoproteins or phospholipoproteins respectively. Their molecular weight depends on type and origin of the Fc gamma R-coated cell and was determined between 40 and 115 KD. Fc gamma R can be estimated by means of rosetting assay or binding experiments with isotopic or fluorescein labeled immune complexes or aggregated IgG respectively ...

Placental Fc receptors and the transfer of maternal IgG

Transfusion Medicine Reviews, 2000
HE TRANSMISSION of specific immunity from mother to young was first described by Paul Ehrlich in 1892, who observed that the young mice from dams made resistant to toxins were also immune to the same toxins. ~ This immunity was limited in extent and time, and appeared to originate from the selective transfer of maternal antibody.
