Complement receptor-mediated signal transduction in human

Complement receptors are membrane proteins expressed on the surface of immune cells. They interact specifically with complement factors leading to the removal of antigen from the circulation. In addition to promoting microorganism destruction by memebrane attack complex (MAC) , the complement system exerts a wide-ranging influence on the activities of cells involved in the immune response. 2012-07-09 Complement receptor 3 (CR3) and CD36 have been suggested to be important in this process, although the mechanism by which this modulation occurs is still unclear.

Complement receptor (CR) 3 is a bona fide phagocytic receptor for Borrelia burgdorferi, the causative agent of Lyme borreliosis [1, 2].CR3 is also the receptor for the opsonin iC3b, a final degradation product of the complement component C3 [3, 4].The transit of B. burgdorferi through the blood during the dissemination phase exposes the spirochete to serum components, including complement [].

Complement-Opsonized Nano-Carriers Are Bound by Dendritic Cells (DC) via Complement Receptor (CR)3, and by B Cell Subpopulations via CR-1/2, and Affect the Activation of DC and B-1 Cells. 2012-01-01 2018-05-16 2020-05-04 The adhesion of neutrophils to endothelial cells is a central event leading to diapedesis and involves the binding of the I-domain of β 2 integrins (CD11/CD18) to endothelial ICAMs. In addition to the I-domain, the β 2 integrin complement receptor 3 (CR3) (CD11b/CD18) contains a lectin-like domain (LLD) that can alter leukocyte functions such as chemotaxis and cytotoxicity.

This prevents further progression of the complement pathway, providing another mechanism by which the complement pathway may be regulated.

Complement Receptor 3-Mediated Inhibition of Inflammasome Priming by Ras GTPase-Activating Protein During Francisella tularensis Phagocytosis by Human Mononuclear Phagocytes. Hoang KV(1), Rajaram MVS(1), Curry HM(1), Gavrilin MA(2), Wewers MD(2), Schlesinger LS(1)(3). 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, 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.
