bp(GO:"complement activation, classical pathway")
The inhibitory effect of heme on the classical pathway is in agreement with in vitro functional assays showing that heme is capable of activating only the alternative pathway in human sera. PubMed:26875449
In contrast to its overactivating effects on the alternative pathway, heme inhibits the classical pathway. It binds to C1q, alters its electrostatic properties, and hampers the recognition of target molecules. This results in a reduction of classical pathway C3 convertase formation and C3b deposition.
