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. C3b is further degraded to iC3b, C3c and C3dg, products that serve as ligands for selective complement receptors on leukocytes.

This prevents further progression of the complement pathway, providing another mechanism by which the complement pathway may be regulated. iC3b is thought to play a role in inducing tolerance, binding complement receptor type 3 on antigen presenting cells and stimulating them to produce transforming growth factor beta2 and interleukin-10.

Upon stimulation, however, expression of CD11b was up‐regulated also on CD4+cells. Complement receptor 3 (CR3; CR3, CD11b/CD18, and Mac-1) is one of the major phagocytic receptors expressed on microglia (Ehlers, 2000) and is a dimeric receptor comprised of CD18 and its unique subunit CD11b (Ivashkiv, 2009; Linnartz and Neumann, 2013). Here, we revealed the critical role of complement receptor 3 (CR3), a microglia-specific pattern recognition receptor, in Nox2 activation and subsequent dopaminergic neurodegeneration by using paraquat and maneb-induced PD model. 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.

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 (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 [].

We studied how tyrosine kinase Syk (spleen tyrosine kinase) and cofilin control phagocytosis of degenerated myelin by CR3 in microglia and macrophages. Syk is a non-receptor tyrosine kinase that CR3 recruits to convey cellular functions.

All of The C3a receptor also known as complement component 3a receptor 1 (C3AR1) is a G protein-coupled receptor protein involved in the complement system. of complement component 3; the other is C3b. C3a is a 77 residue anaphylatoxin that binds to the C3a receptor (C3aR), a class A G protein-coupled receptor.
