The complement system, which is made up of more than 30 serum and cell surface components, works with the innate and acquired immune systems to recognize and get rid of pathogens. Following the activation of the complement system, a series of events involving proteolysis and assembly lead to the cleavage of the third complement component (C3). The activation pathway refers to the cascade that leads to C3 cleavage. The classical, lectin, and alternative pathways are the three types of activation.
The complement cascade is a double-edged sword that causes phagocytosis and inflammation while also providing defense against viral and bacterial invasion. If complement is not properly controlled, it can cause significant pathological damage to erythrocytes (hemolysis), kidney basement membrane and attached endothelial and epithelial cells (nephritis), joint synovium (arthritis), and blood vessels (vasculitis).
