C4b astrocytes
WebC4b binds to CR1, and immune adherence to erythrocytes can be mediated by a CR1–C4b interaction, rather than by CR1–C3b. During normal complement activation, much more C3b is fixed than C4b, and it is unlikely that C4b has an important role in receptor-mediated adhesion or ingestion mechanisms. WebOct 26, 1998 · Complement C4 is the product of two closely related genes, C4A and C4B, that are located in the class III region of the major histocompatibility complex (MHC) [2]. The protein is produced as a single polypeptide of approximately 210 kDa and is cleaved after synthesis into three polypeptide chains, the α, β, and γ chains. ... Human astrocytes ...
