Papeis opostos de FcγRIIb e FcγRIII na inflamação articular e no clearance bacteriano na artrite séptica induzida por Staphylococcus aureus
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE BIOQUÍMICA E IMUNOLOGIAPrograma de Pós-Graduação em Bioquímica e ImunologiaUFMG, 2018-07-16)
Septic arthritis is an articular disease caused by a microorganism. Several viruses, fungi and bacteria can cause this disease, but Staphylococcus aureus is the most common cause, due to its numerous virulence factors and ...
CMV-encoded Fcγ receptors: modulators at the interface of innate and adaptive immunity
(2014-10-07)
The constant region of IgG antibodies mediates antiviral activities upon engaging host Fcγ receptors (FcγRs) expressed by a variety of immune cells, such as antibody-dependent cellullar cytotoxcity (ADCC) executed by natural ...

Human Cytomegalovirus Fcγ Binding Proteins gp34 and gp68 Antagonize Fcγ Receptors I, II and III
(2014-05-15)
Human cytomegalovirus (HCMV) establishes lifelong infection with recurrent episodes of virus production and shedding despite the presence of adaptive immunological memory responses including HCMV immune immunoglobulin G ...

A novel assay for detecting virus-specific antibodies triggering activation of Fcγ receptors
(2013-01-31)
IgG responses are crucial in antiviral defence and instrumental for the serodiagnosis of infections. Fcγ receptors (FcγRs), which recognize the Fc-part of IgG, differ regarding their IgG binding affinity, IgG subclass ...

Fcγ Receptor IIa (FCGR2A) Polymorphism Is Associated With Severe Respiratory Syncytial Virus Disease in Argentinian Infants
(Frontiers Media, 2020-12)
Background: Most patients with respiratory syncytial virus (RSV) infection requiring hospitalization have no risk factors for severe disease. Genetic variation in the receptor for the Fc portion of IgG (FcγR) determines ...
Signaling capacity of FcγRII isoforms in B-CLL cells
(Pergamon-Elsevier Science Ltd, 2005-11)
Two main isoforms of Fcγ receptor II (CD32) have been described in humans: activatory FcγRIIA and inhibitory FcγRIIB. We have previously reported that B cells from a subset of chronic lymphocytic leukemia (B-CLL) patients ...
Expression of Fcγ receptors type II (FcγRII) in chronic lymphocytic leukemia B cells [4]
(American Society of Hematology, 2003-10)
We have read with interest the paper from Damle et al analyzing the surface membrane phenotype of B lymphocytes in chronic lymphocytic leukemia (B-CLL). The authors stated that the leukemic cells from all B-CLL patients ...
