| − | ROS production was totally abolished with 100 M NADPH oxidase inhibitor diphenyleneiodonium chloride (DPI). ROS production steeply increased and peaked at 30 min. In macrophages the extracellular ROS production was weaker but persisted compared to monocytes. Data will be the mean of at least three independent experiments.

ROS production was absolutely abolished with 100 M NADPH oxidase inhibitor DPI. Quantification of the extracellular ROS generated by macrophages following PMA treatment. Inhibitor DPI decreased ROS production below manage level.

Monocytes were treated with five mM Nacetyl cysteine (NAC) for 1 h prior remedy. Then, cells had been stained with ten M CMH2DCFDA straight away prior to remedy with 1, 10, one hundred or 1000 ng/ml PMA. Mean fluorescence was measured by way of flow cytometry. Data was normalised to the untreated dye control. The ROS formation was at highest level at 100 ng/ml PMA. ROS scavenger NAC decreased the intracellular ROS burden.
