Human PBMC was stimulated with 0.17 ng/ml ABH for 16 h. IL-12 production was quantified by flow cytometry (right panels). The flow cytometric data in the right panels represent three gated populations of CD14-positive and negative cells. Results of ABH stimulated and unstimulated samples shown as open and closed histograms respectively. The region indicated by the bar represents IL-12-producing cells (shown in left panels). Data shown are representative of three independent experiments.
