ic3b造句

• It binds to iC3b ( inactive derivative of C3b ), C3dg, or C3d.
• This protein is also a receptor for the complement component 3 fragments C3b and iC3b.
• Next, C3b is broken down progressively to first iC3b, then C3c + C3dg, and then finally C3d.
• CR3 has also been shown to mediate phagocytosis of the Lyme disease causing bacterium, " Borrelia burgdorferi ", in the absence of iC3b opsonization.
• CD21 ( also called C3d receptor, CR2, Epstein Barr virus receptor or EBV-R ) is the receptor for EBV and for C3d, C3dg and iC3b.
• Because primate erythrocytes express complement receptor 1 ( CR1 ) on their surface and having binding specificity to C4b, C3b, or iC3b, erythrocytes accumulate on the microbe via CR1-complement binding.
• The CR2-CD19-CD81 complex is often called the B cell coreceptor complex, because CR2 binds to antigens through attached C3d ( or iC3b or C3dg ) when the membrane IgM binds to the antigen.
• The cascade begins to work from C1 to C3b through C4b, C3b being further transformed to iC3b ( inactive derivative of C3b ), all of which, C4b and thereafter, remain to bind to the surface of the microbe.
• Host cells don't accumulate cell surface C3b ( and the proteolytic fragment of C3b called iC3b ) because this is prevented by the complement regulatory proteins, while foreign cells, pathogens and abnormal surfaces may be heavily decorated with C3b and iC3b.
• Host cells don't accumulate cell surface C3b ( and the proteolytic fragment of C3b called iC3b ) because this is prevented by the complement regulatory proteins, while foreign cells, pathogens and abnormal surfaces may be heavily decorated with C3b and iC3b.
• After C3b is degraded into a fragment iC3b ( inactive derivative of C3b ), then cleaved to C3dg, and finally to C3d, which continue to bind to microbal surface, B cells express complement receptor CR2 ( CD21 ) to bind to iC3b, C3dg, or C3d.
• After C3b is degraded into a fragment iC3b ( inactive derivative of C3b ), then cleaved to C3dg, and finally to C3d, which continue to bind to microbal surface, B cells express complement receptor CR2 ( CD21 ) to bind to iC3b, C3dg, or C3d.
