Effects of PM-a and PM-b on the biological characteristics of MLE 12 cells. A Intracellular reactive oxygen species are measured by flow cytometry. MLE 12 cells were treated with PM-a (100 μg/ml) or PM-b (100 μg/ml) for 30 min. Con-a and con-b indicate the control groups of PM-a and PM-b, respectively. B Protein expressions related to inflammatory signals and autophagy pathway were detected by Western blotting. MLE 12 cells were treated with PM-b (100 μg/ml) for the indicated hours
