WebThree initiating pathways of complement activation are described: the classical pathway (CP), the lectin pathway (LP), and the alternative pathway (AP) (Figure 1). The CP is triggered by immune complexes and the LP is initiated by the recognition of exposed glycans (mannose residues) on bacterial surface. WebThe complement system in blood plasma is a major mediator of innate immune defence. The function of complement is to recognize, then opsonize or lyse, particulate materials, including bacteria, yeasts and other microrganisms, host cell debris and altered host cells. There are three ways in which the complement system protects against infection.
