Figure 2

The level of (a) IL-6 and (b) IL-8 in A549 cells treated with FCBD and CBD. Cells were treated with 300 ng/mL TNFα, 4.1 μg/mL FCBD (FCBD) and CBD at different concentrations for 4 h. Dexamethasone (Dex; 4 μg/mL) served as a positive control. Control (0.6% v/v methanol) treatment served as the solvent (vehicle) control; TNFα is TNFα+ solvent control treatment. Error bars indicate ± sem (n = 3). Bars labeled with different letters are significantly different from all combinations of pairs according to the Tukey–Kramer HSD test (P ≤ 0.05).
