背景资料:The C3c component is central in both complement activation pathways, with different specific proteolytic systems cleaving it to form C3 convertase. Cleavage of C3 releases C3a and the C3b fragment which is part of the alternative C3 convertase. C3 levels can be low because of decreased synthesis or due to consumption. High C3 levels are seen in highly acute or chronic inflammation, hepatic cholestasis and during the third trimester of pregnancy.Unwanted complement activation is a major cause of tissue damage in various pathological conditions and contributes to quite a few immune complex diseases.Compstatin is an effective inhibitor of the activation of complement component C3 and thus blocks a central and essential step in the complement cascade. The specific binding site on C3, the configuration in the bound form, and the exact mode of action of compstatin are unknown. The crystal structure of compstatin in complex with C3c reveals that the compstatin-binding site is formed by the macroglobulin (MG) domains 4 and 5. This binding site is part of the structurally stable MG-ring created by domains MG1–6 and is distant from any other known binding site on C3. Compstatin does not modify the conformation of C3c, while compstatin itself undergoes a large conformational alteration upon binding.

文献和实验C3是补体二条激活途径的关键分子,C3活化后裂解为C3a、C3b两个片段,C3a很快被血清羧肽酶N裂解为C3adesarg,C3b被H、I因子灭活为C3bi,经蛋白酶水解为C3c、C3d、C3dg等,检测这些裂解产物即可反映C3的活化程度。C3a的定量检测采用竞争性抑制放射免疫法。其原理为用“I标记C3(I-C3)”与待测样本、兔抗人C3a多克隆抗体一起孵育,待测样本中的C3a(未标记抗原)能竞争性地与抗C3a结合,使C3a复合物(B)增多,而“I-C3”游离出来(F),根据B%来判断待测样本
