The classical pathway is activated by C1q-mediated recognition of the target. Further activation of this pathway causes C4b and its cleavage product iC4b to accumulate in the tissues. C4b binds to C2 ...
The complement system consists of a number of small proteins found in the blood, in general synthesized by the liver, and normally circulating as inactive precursors (pro-proteins). When stimulated by ...
The complement system is known to play critical roles in pathogen identification, initiation of innate immune responses and facilitation of adaptive immune responses. Several studies have suggested ...
