C8 alpha-gamma induces the polymerization of 10-16 molecules of C9 into a pore-forming structure known as the membrane attack complex.[1]. Similar hydrophobic sites on C8 and C9 molecules are exposed when they bind to the complex, so they can also insert into the bilayer. These cells can, therefore, be lysed by MAC. All three pathways of the complement system (classical, lectin and alternative pathways) initiate the formation of MAC. It involves deficiencies of C5, C6, C7, and C8.
