Fig. 5. Inhibition of PM10-induced IL-6 by LL-EA and oleanolic acid in keratinocytes. HaCaT was pre-treated with different concentrations of LL-EA (2.5, 5, 10 μg/mL) or oleanolic acid (2.5, 5, 10 μg/mL) for 6 h, and after that PM10 (50 μg/mL) was treated for 24 h. Supernatants were used to analyze Enzyme linked immunosorbent assay (ELISA). Values are presented as the mean ± SD of three determinations (n=3). *p<0.05, **p<0.01 versus PM10 treatment group; ##p<0.01 versus control group.
