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.

Complement C3b/C3d and cell surface polyanions are recognized by overlapping binding sites on the most carboxyl-terminal domain of complement factor H J Immunol . 2002 Dec 15;169(12):6935-44. 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. C4b C2b C3b acts as a C5 convertase and cleaves C5 into C5a and C5b. C3b itself is produced by all three pathways of complement (Law, S.K.A.

Complement is mainly. Complement System The complement system, specifically through the actions of proteins C3a and C3b, destroys microbes. – Comprises inactive proteins that  17 Jan 2016 What is Complement C3 Blood Test?

Complement C3 ( C3 ) in human serum. Complement is mainly. Complement System The complement system, specifically through the actions of proteins C3a and C3b, destroys microbes. – Comprises inactive proteins that  17 Jan 2016 What is Complement C3 Blood Test? (Background Information).

Inhibits these pathways by cleaving three peptide bonds in the alpha-chain of C3b and two bonds in the alpha-chain of C4b thereby inactivating these proteins. Deposition of nascent C3b on cell surfaces during complement (C) activation can opsonize cells for destruction.1-4 Cancer cells can activate the alternative or classical C pathway, which results in the covalent attachment of C3b molecules, thus perpetuating C activation and promoting cell lysis.5-8 Cell-bound C3b can be degraded to inactive forms, iC3b and then C3dg, by C control proteins on Synonyms.

Complement component 3 (C3) plays a central role in the activation of the complement system. C3 cleavage by C3-convertase produces C3b and iC3b. C3b leads to an inflamatory response and also covalently binds to microbial cell surfaces aiding in opsonization of the microbe. From the laboratory of Ronald P. Taylor, PhD, University of Virginia.

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. complement protein C3, C3b and iC3b, were present on the bacterial surface after incubation in human serum. In the present studies, C3b and iC3b were found on several serotype 5 and 8 S. aureus strains after incubation in human serum.
