The development of membranoproliferative glomerulonephritis (MPGN) is associated with uncontrolled activation of the complement alternative pathway. This dysregulation is related either to C3 nephritic factor (C3NeF), an auto-antibody directed against the alternative C3 convertase, or to homozygous loss-of-function mutation of

The complement regulatory enzyme, C3b inactivator (C3bINA), has been purified from human serum by affinity chromatography on an anti-C3bINA Sepharose column. Subsequent chromatography on DEAE-cellulose and removal of IgG with anti-IgG Sepharose resulted in a product which was found to

Tetartohedral crystal twinning is discussed as a particular case of (pseudo)merohedral twinning when the number of twinned domains is four. Tetartohedrally twinned crystals often possess pseudosymmetry, with the rotational part of the pseudosymmetry operators coinciding with the twinning operators. Tetartohedrally

Factor I (FI) is a crucial inhibitor controlling all complement pathways due to its ability to degrade activated complement proteins C3b and C4b in the presence of cofactors such as factor H, C4b-binding protein, complement receptor 1 or CD46. Complete
