A significant lowering of pro-inflammatory, C3 (86.9%) and microglial activation markers, MCP-1 (87.5%) and YKL-40 (72.7%), was evident. PubMed:22791904
NF-κB directly regulates the transcription of a multitude of proteins of the complement pathway that are involved in antigen presenting such as C3 (complement component 3) [241], Bf (complement factor B) [242], and CR2 (complement receptor 2) [243] as well as acute phase proteins such as C4 (complement factor 4) [244] and C4BPA (complement factor 4 binding protein) PubMed:28745240
Furthermore, the incubation of serum or whole blood with heme induces deposition of activation fragments (C3b, iC3b, C3dg) of complement component 3 (C3) at the surface of erythrocytes [77]. PubMed:26875449
Molecular docking predicted the interaction of heme in close proximity to a thioester bond, known to be important for the activation of C3. PubMed:26875449
However, in contrast to its effect on C3, exposure of C1q to heme was demonstrated to inhibit its functions in vitro [89,90] (Figure 3B). PubMed:26875449
