Effects of CARB and FP on ROS production in bronchial epithelial cells. 16-HBE (n = 6) 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). Data are expressed as the percentage of ROS-positive cells ± SD. Representative histogram plots are also shown
