Other studies have also shown that genetic mutations in certain complement pathways increase the risk of macular degeneration. (hcplive.com)
Activation of these circulating complement proteins in response to an injurious or infectious challenge results in a self-amplifying cascade of proteolytic reactions through any one of four major identified pathways (Figure 1 ). (biomedcentral.com)

Anaphylatoxin4
Little is known about the role of C3a, beyond the fact that is an anaphylatoxin," Fernandez-Godino said. (hcplive.com)
Targeting the complement system in bacterial meningitis has the goal to decrease complications deriving from the uncontrolled, massive inflammatory response in the CNS, mainly driven by anaphylatoxin C5a production. (medscape.com)
2014). C4a does not share the inflammatory activities of C3a and C5a, and therefore should not be considered as an anaphylatoxin (Barnum, 2015). (medscape.com)
Targeting the amplification loop or C3 has the benefit of reducing complement amplification and concurrent massive anaphylatoxin production irrespective of the initiation pathway, but was not found to be beneficial in experimental meningitis models ( Table 3 ). (medscape.com)
C3aR1
Notably, XFBD attenuated C3a and C5a generation, inhibited the expression of C3aR and C5aR and suppressed the activation of JAK2/STAT3/SOCS3 and NF-κB signaling pathway in lung tissues and macrophages induced by IgG-IC. (bvsalud.org)
Macrophages2
In vitro, alveolar macrophagesinflammation models induced by IgG-IC were performed and treated with different dosage of XFBD-containing serum to investigate the protective role and molecular mechanisms of XFBD. (bvsalud.org)
Moreover, in vitro experiments, we verified that Colivelin TFA (CAF, STAT3 activator) and C5a treatment markedly elevated the IgG-IC-triggered inflammatory responses in macrophages and XFBD weakened the effects of CAF or C5a. (bvsalud.org)
