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 classical pathway is activated by an antibody binding to a target antigen, forming a complex. IgM has the greatest ability to activate complement among all immunoglobulins. C- reactive protein can also activate the classical pathway.
