WebThe lectin pathway or lectin complement pathway is a type of cascade reaction in the complement system, similar in structure to the classical complement pathway, [1] in that, after activation, it proceeds through the action of C4 and C2 to produce activated complement proteins further down the cascade. 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.
