C3b itself is produced by all three pathways of complement (Law, S.K.A. and Reid, K.B.M. (1995)) when native C3 is cleaved releasing C3a. C3d is prepared at CompTech from purified human C3. The C3 is converted to C3b by treatment with the natural human C3 convertase and this C3b is converted to iC3b by treatment with complement factors H and I.

Molekyler som finns på ytan hos en del B-lymfocyter och makrofager och som känner igen och binder till komplementkomponenterna C3b, C3d, C1q och C4b. C3b is essential to the function of all 3complement pathways. Initiation of each pathway generates proteolytic enzyme complexes (C3 convertases) which binds the target surface. These enzymes cleave a peptide bond in C3 releasing the anaphylatoxin C3a and activating C3b. Most of the C3b created during complement activation. Complement component 3 (C3) plays a central role in the activation of the complement system.

2017-01-01 Classical Pathway. This pathway involves complement components C1, C2 and C4.The pathway is triggered by antibody-antigen complexes binding to C1, which itself has three subcomponents C1q, C1r and C1s.The pathway forms a C3 convertase, C4b2a, which splits C3 into two fragments; the large fragment, C3b, can covalently attach to the surface of microbial pathogens and opsonise them; the … 2009-06-07 C3b Last updated October 11, 2020 The classical and alternative complement pathways.. C3b is the larger of two elements formed by the cleavage of complement component 3, and is considered an important part of the innate immune system.C3b is potent in opsonization: tagging pathogens, immune complexes (antigen-antibody), and apoptotic cells for phagocytosis. 2018-08-23 C3b is generated by proteolysis of C3 on complement activation. It recruits factor B (FB), which is subsequently cleaved into Bb, and thus the alternative pathway (AP) C3 convertase C3bBb is formed, and a positive feedback amplification loop leads to further convertase assembly.

2004-05-01 C3 plays a central role in the activation of the complement system. Its processing by C3 convertase is the central reaction in both classical and alternative complement pathways. After activation C3b can bind covalently, via its reactive thioester, to cell surface carbohydrates or immune aggregates.

doi: 10.4049/jimmunol.169.12.6935. Only a C3b molecule combines with C4bC2b to form the final proteolytic complex complement pathway. The complex of C4bC2bC3b forms an opsonic macromolecular coat on the target cells and makes it susceptible to immune adherence by the C3b receptor on the phagocytic cells.
