Induction of PLD activity by CRP or cross-linked IgG1 in IFN-γ treated U937 cells. IFN-γ-treated U937 cells were incubated with medium (basal), CRP (20 μg/ml) or IgG1 (40 μg/ml followed by F(ab)′₂ anti-IgG). Following the addition of [³H]butanol, incorporation of phosphatidylbutanol was measured and expressed as a percentage of total [³H]palmitate incorporation. The bars represent the mean ±SEM of four independent experiments.
