Clarithromycin inhibits IL-13–stimulated STAT6 phosphorylation. MRC5 cells were stimulated by exposure to 50 ng/mL IL-13 in the presence or absence of clarithromycin. Phosphorylated STAT6 in the cell lysates of MRC5 cells was analyzed by Western blot. Bars are depicted as mean ± SD. The same experiments were performed three times; a representative result of three individual experiments is shown. **; P < 0.001 compared with control, ^#; P < 0.05, ^##; P < 0.001 compared with no clarithromycin, NS; not significant
