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.

The adhesion molecules used by monocytes for migration across endothelium include Complement receptor (CR) 1, 3, and 4 function as opsonins which stimulate phagocytosis, whereas CR2 is expressed only on B cells as a co-receptor. Red blood cells (RBCs) also express CR1, which enables RBCs to carry complement-bound antigen-antibody complexes to the liver and spleen for degradation. a. ^ B: B cell. 3 Department of Molecular Biology and Genetics—Structural Biology, Aarhus University, Aarhus, Denmark Complement receptors (CR) 3 and 4 belong to the family of beta-2 (CD18) integrins. CR3 and CR4 are often co-expressed in the myeloid subsets of leukocytes, but they are also found in NK cells and activated T and B lymphocytes.

Upon fibrinogen extravasation across leaky vessels (i.e., break down of the blood-brain barrier), fibrinogen is converted by thrombin to insoluble fibrin. Based on published studies, this signaling pathway highlights fibrin as a CD11b/CD18 (complement receptor; CR3) integrin receptor ligand that regulates innate immunity.

Red blood cells (RBCs) also express CR1, which enables RBCs to carry complement-bound antigen-antibody complexes to the liver and spleen for degradation. In addition, complement fragments associated with immune complexes also activate cells such as macrophages and dendritic cells through specific complement receptors (e.g., Mac-1, complement receptor 3, CR3 and CD11c, CR4). 2012-01-18 2013-10-08 Complement receptor-3 negatively regulates the phagocytosis of degenerated myelin through tyrosine kinase Syk and cofilin SmadarHadas 1, MayaSpira 1,2, Uwe-KarstenHanisch 3, FannyReichert 1 and ShlomoRotshenker 1* Abstract Background: Intact myelin, which normally surrounds axons, breaks down in Wallerian degeneration following Complement component C3 is central to opsonization. Its first cleavage product, C3b, forms the multisubunit enzyme, C3bBb, which proteolytically cleaves additional C3 molecules on the pathogen surface.

3 Mar 2020 The terminal galactose is critical for initial contact with the human cervical mucosa via an interaction with the I-domain of complement receptor 3 (

The most well‐characterized host cell receptors for Leishmania recognition are CR3, FcγRs, MR, scavenger receptor, and some TLRs [3, 4]. However, it is not clear whether engagement of specific macrophage surface receptors by Leishmania influences phagosome maturation and whether this event correlates with parasite survival.

Complement receptor 3 (CR3) is a heterodimer of α (CD11b) and β (CD18) transmembrane glycoproteins. While the α-chain is unique to CR3, the β subunit is shared by LFA1, CR4, and αdβ2, all belonging to the β2 integrin leukocyte receptor family.

Integrins are heterodimeric proteins consisting of an α-chain-subunit that is noncovalently associated with one or more β-chains. In this study, we uncovered a novel role for the microglial complement receptor 3 (CR3) in the regulation of soluble β-amyloid (Aβ) clearance independent of phagocytosis. Unexpectedly, ablation of CR3 in human amyloid precursor protein-transgenic mice results in decreased, rather than increased, Aβ accumulation.
