Phosphatidic acid (PA), a molecule that is rapidly produced by the stimulated turnover of phospholipids in a variety of cells including blood neutrophils, elicited NADPH-dependent superoxide anion (O2-) production in detergent extracts from membranes of resting pig neutrophils. The stimulatory effect of PA was independent of cytosolic factors, differing from arachidonic acid and sodium dodecyl sulfate which, on the contrary, absolutely required the presence of cytosol to elicit the same result. The O2(-)-forming activity of the detergent extract activable by PA, as that by sodium dodecyl sulfate and arachidonic acid plus cytosol, was found in the chromatographic fractions containing cytochrome b558 and presented a chromatographic profile identical to that of the activated NADPH oxidase, which was obtained from neutrophils prestimulated with phorbol 12-myristate 13-acetate. The PA-induced NADPH-dependent O2(-)-forming activity showed kinetic properties and sensitivity to the inhibitors similar to the classical ones of the activated neutrophil NADPH oxidase. The data suggest that, in this cell-free system, PA may stimulate O2- formation by direct interaction with latent NADPH oxidase of neutrophils or with some of its regulatory components.
