Effects of CARB and FP on ROS production in nasal and airway epithelial cells. Nasal epithelial cells (RPMI 2650) (a) and airway epithelial cells (H292, n = 2) (b) cells were cultured in the presence and absence of CSE (10 %), CARB (10⁻⁴ M) and FP (10⁻⁸ M) for 18 h and then were used for assessing ROS production using flow cytometry (see “Materials and methods” for details). Representative histogram plots are shown
