Pilus Adhesin RrgA Interacts with Complement Receptor 3, Thereby

Unexpectedly, ab … Recent genetic evidence supports a link between microglia and the complement system in Alzheimer's disease (AD). A long-standing hypothesis is that complement receptors (CRs), especially CR3, mediate sinking phagocytosis, but evidence is lacking. Alternatively, CRs have been reported to induce membrane ruffles or phagocytic cups, akin to those induced by Fcγ receptors (FcγRs), but the details of these events a … Yefenof E. (2002) Complement Receptor 3 (CR3): A Public Transducer of Innate Immunity Signals in Macrophages. In: Keisari Y., Ofek I. (eds) The Biology and Pathology of Innate Immunity Mechanisms. Advances in Experimental Medicine and Biology, vol 479. Complement receptor 3 mediates both sinking phagocytosis and phagocytic cup formation via distinct mechanisms The complement receptor 3 (CR3; CD11b/CD18) is present exclusively on leukocytes, particularly on NK cells, monocytes and polymorphonuclear neutrophils.

Complement receptor 3

We showed that in the spleen, complement-opsonized NC preferably targeted splenic B cells [7] by engagement of CR1/2 [14]. 2002-12-01 Here we show that deficiency of complement receptor 3 (CR3), the main receptor for iC3b, enhances the severity of spontaneous renal disease in Cfh –/– mice. This effect was found to be dependent on CR3 expression on bone marrow–derived cells. 2020-04-28 Complement Receptor 3 (CD11b/CD18) Mediates Type I and Type II Phagocytosis During Nonopsonic and Opsonic Phagocytosis, Respectively September 2002 The Journal of Immunology 169(4):2003-9 Complement receptor type 1 (CR1) also known as C3b/C4b receptor or CD35 (cluster of differentiation 35) is a protein that in humans is encoded by the CR1 gene. [3] [4] CR1 The complement receptor CR3 (CD11b/CD18, Mac-1) mediates the phagocytosis of complement protein (C3bi)-coated particles.

Red blood cells (RBCs) also express CR1, which enables RBCs to carry complement-bound antigen-antibody complexes to the liver and spleen for degradation.

CR3 exists as an integrin heterodimer composed of an alpha (α M or CD11b) and a beta (β 2 or CD18) subunit. Aberrant elongated and cylindrical Fcγ receptor–mediated phagocytic cups in Itgb2 −/− (complement receptor 3 [CR3] KO) macrophages. A , ingestion of an IgG-opsonized human red blood cell (hRBC) by a WT macrophage. 3D time-lapse imaging was performed by spinning disk confocal microscopy.
