Inhibition of FcγR-mediated phagocytosis by IVIg is independent of IgG-Fc sialylation and FcγRIIb in human macrophages.
In immune thrombocytopenia and warm autoimmune hemolytic anemia, circulating immunoglobulin G (IgG)-opsonized blood cells are cleared from the circulation by macrophages. Administration of intravenous immunoglobulin (IVIg) can prevent uptake, but the exact working mechanism is not known. The prevailing theory from murine studies, which states that Fc-sialylated IgG alters the balance between ac...
متن کاملInhibition of Fc g Receptor - Mediated Phagocytosis by a Nonphagocytic Fc g Receptor
There are three major classes of human Fcg receptors (FcgRI, FcgRII, and FcgRIII) and various isoforms of each class are capable of mediating phagocytosis. FcgRIIA is an unusual Fcg receptor in that it transmits a phagocytic signal in the absence of an additional receptor subunit. The cytoplasmic domain of FcgRIIA contains a conserved motif containing two copies of the sequence YXXL. The tyrosi...
متن کاملRespiratory Syncytial Virus Persistence in Macrophages Upregulates Fcgamma Receptors Expression
Viruses can persist in differentiated cells (i.e., macrophages) over long periods of time, altering host cells functions but not inducing their death. We had previously reported that, in early passages (14-40) of a murine macrophage-like cell line persistently infected with respiratory syncytial virus (RSV) (MfP), FcgR-mediated phagocytosis and expression of FcgRIIB/RIII on the cell membrane we...
متن کاملHyposialylated IgG activates endothelial IgG receptor FcgRIIB to promote obesity-induced insulin resistance
Type 2 diabetes mellitus (T2DM) is a common complication of obesity. Here, we have shown that activation of the IgG receptor FcgRIIB in endothelium by hyposialylated IgG plays an important role in obesity-induced insulin resistance. Despite becoming obese on a high-fat diet (HFD), mice lacking FcgRIIB globally or selectively in endothelium were protected from insulin resistance as a result of t...
متن کاملA Regulatory Role for Src Homology 2 Domain–Containing Inositol 5′-Phosphatase (Ship) in Phagocytosis Mediated by Fcγ Receptors and Complement Receptor 3 (αMβ2; Cd11b/Cd18)
The Src homology 2 domain-containing inositol 5'-phosphatase (SHIP) is recruited to immunoreceptor tyrosine-based inhibition motif (ITIM)-containing proteins, thereby suppressing phosphatidylinositol 3-kinase (PI 3-kinase)-dependent pathways. The role of SHIP in phagocytosis, a PI 3-kinase-dependent pathway, is unknown. Overexpression of SHIP in macrophages led to an inhibition of phagocytosis ...
