Complement activation by the alternative pathway and macrophage enzyme secretion in the pathogenesis of chronic inflammation.

Immunology, 1977
A number of stimuli known to induce acid hydrolase secretion from cultured macrophages were examined for their ability to activate C3 via the alternative pathway of the complement system. Loss of haemolytically active C3 was checked in normal and C4-deficient guinea-pig serum.

Reduced activity of DAF on complement enzymes bound to alternative pathway activators. Similarity with Factor H.

Immunology, 1991
Attachment of C3b to activators of the alternative pathway of complement results in a decrease in regulatory activity expressed by Factor H. Decay-accelerating factor (DAF) and Factor H were found to exhibit quantitatively similar decreases in regulatory activity toward the C3 convertase (C3b,Bb) bound to activators, such as zymosan (Zym) and rabbit ...
