Concentration–response analysis of budesonide and formoterol attenuation of Poly I:C-induced cytokines responses in human airway epithelial cells. Concentration–response analysis measuring (A) IL-6 and (B) IL-8 was conducted for cells exposed to Poly I:C (1 µg/mL) treated with fixed concentration of budesonide (10 nM) with increasing log concentrations of formoterol (0.0001, 0.001, 0.01, 0.1, and 1 nM). Concentration–response analysis measuring (C) IL-6 and (D) IL-8 for cells exposed to Poly I:C (1 µg/mL) treated with fixed concentration of formoterol (0.01 nM) with increasing log concentrations of budesonide (0.1, 1, 10, 100, and 1000 nM). Results are shown as mean + SEM. The standard error of means is represented by the error bars attached to each point. n = 4
