Abstract/OtherAbstract:
Complement component 5a (C5a) is a 74 amino acid glycoprotein and an important proinflammatory mediator that is cleaved enzymatically from its precursor, C5, on activation of the complement cascade. C5a is quickly metabolised by carboxypeptidases, forming the less-potent C5a desArg. C5a and C5a desArg interact with their receptors (C5aR and C5L2), which results in a number of effects which are essential to the immune response. C5a has a broad range of biological effects throughout the human body because the widespread expression of C5a receptors throughout the human organs enables C5a and C5a desArg to elicit a broad range of biological effects. Recently, accumulating evidence in humans and experimental animal models shows that the C5a-C5aR axis is involved in the development of atherosclerosis lesions. The absence or blockade of C5aRs greatly reduces the formation of atherosclerotic lesions or wire-injury-induced neointima formation in atherosclerosis-prone mice. Serum C5a level was related to the major adverse cardiovascular events in patients with advanced atherosclerosis and those with drug-eluting stent implantation. Thus, the C5a-C5aR axis may be a significant pathogenic driver of arteriosclerotic vascular disease, making C5a-C5aR inhibition an attractive therapeutic strategy.
