In the alternative pathway, C3b binds to Factor B. Factor D releases Factor Ba from Factor B bound to C3b. The complex of C3b (2)Bb is a protease which cleaves C5 into C5b and C5a. C5 convertase is ...

Three pathways have now been described in the complement system — the classic, alternative and lectin. A fourth, lytic pathway is added by some authors for membrane attack complex.

When you have C3 glomerulopathy, your alternative complement system is overactive. When it reaches this state of high alert, it starts to break down proteins in your body called complement 3 (C3 ...

The complement pathway is a part of the innate immune system and C3 activation is required for the classical complement pathway, the alternative complement pathway, and the lectin pathway.

Results from the Phase I and II trials of Ruxoprubart in PNH patients have demonstrated its potential as a highly selective blocker of the alternative pathway (AP). Unlike other complement blockers, ...
