title: Modulation of monocyte complement synthesis by interferons.
abstract: Recombinant Escherichia coli-derived gamma-interferon has been shown to stimulate synthesis of the second component of complement (C2), factor B and C1 inhibitor, but to inhibit synthesis of the third component (C3). alpha- and beta-interferons stimulate synthesis of factor B and C3 inhibitor, inhibit C5 synthesis but do not alter synthesis of C2. alpha- and beta-interferons act synergistically with gamma-interferon to enhance both factor B and C1-inhibitor synthesis.
