Gene deficiency in activating Fcγ receptors influences the macrophage phenotypic balance and reduces atherosclerosis in mice [PDF]
Immunity contributes to arterial inflammation during atherosclerosis. Oxidized low-density lipoproteins induce an autoimmune response characterized by specific antibodies and immune complexes in atherosclerotic patients.

Protein kinase C controls Fcγ receptor-mediated endocytosis in human neutrophils [PDF]
The aim of this study is to clarify which signaling mechanism operates in Fcγ receptor-mediated endocytosis in human neutrophils. Endocytosis of immune complexes was inhibited by antibodies directed to cell membrane phospholipase C (PLC) and A2 (PLA2 ...

The Solution Structures of Two Human IgG1 Antibodies Show Conformational Stability and Accommodate Their C1q and FcγR Ligands. [PDF]
The human IgG1 antibody subclass shows distinct properties compared with the IgG2, IgG3, and IgG4 subclasses and is the most exploited subclass in therapeutic antibodies. It is the most abundant subclass, has a half-life as long as that of IgG2 and IgG4,

Characterization of Monoclonal Antibodies, TAG1,TAG2 and TAG3 for Neutrophil Fcγ receptor IIIb [PDF]
免疫機序による好中球減少症において, 好中球Fcγ receptor IIIb(Fcγ RIIIb)上の抗原であるNA系抗原やFcγ RIIIを標的とする抗体がしばしば検出される。抗体検出に用いられるパネル好中球と患者好中球のNA系抗原の表現型の同定にはモノクローナル抗体(mAb)または血清抗体が用いられてきた。このたび, NA1抗原認識mAb, TAG1,NA2抗原認識mAb, TAG2,Fcγ RIII認識mAb, TAG3の3つのmAbを作製した。TAG1,TAG2 ...

Influence of Fcγ receptor distribution on mannose receptor mediated phagocytosis [PDF]
In this study the recognition maps obtained by the simultaneous topography and recognition (TREC) imaging revealed that Fcγ receptors are distributed in micro-domains of sizes 4nm to 200nm.

Fcγ receptor II stimulated formation of inositol phosphates in human platelets is blocked by tyrosine kinase inhibitors and associated with tyrosine phosphorylation of the receptor [PDF]
We report that activation of phospholipase C (PLC) by cross-linking of the platelet low-affinity Fcγ receptor II (Fcγ RII) is inhibited by two structurally distinct tyrosine kinase inhibitors, staurosporine and ST271.

The CD47–SIRPα axis has emerged as a critical innate immune checkpoint that suppresses macrophage‐mediated phagocytosis through a canonical “don't eat me” signal and enables tumor immune evasion. We comprehensively summarize the structural and biological features of CD47 and the molecular mechanisms underlying CD47‐mediated regulation of phagocytosis ...
