Effects of SL on STAT6 phosphorylation in DNP-IgE/HSA-sensitized RBL-2H3 mast cell. RBL-2H3 cells were treated with anti-DNP-IgE (110 ng/ml) for 1 h, followed by stimulation with SL (5%) for 1 h, and then with DNP-HSA antigen (25 ng/ml). A STAT6 and p-STAT6 levels were detected by western blotting. B The graphs show STAT6 protein expression relative to no phosphorylation. Data are presented as the mean ± SEM (n = 3). Different letters on each column indicate statistical significance
