Abstract Background Asthma is a chronic airway inflammatory disease characterized by an imbalance in both Thl and Th2 cytokines. Exhaled nitric oxide NO is elevated in asthma and is a potentially useful non-invasive marker of airway inflammation. However the origin and underlying mechanisms of intersubject variability of exhaled NO are not yet fully understood. We have previously described NO gas phase release from normal human bronchial epithelial cells NHBEs tracheal origin . However smaller airways are the major site of morbidity in asthma. We hypothesized that IL-13 or cytomix IL-lp TNF-a and IFN-y stimulation of differentiated small airway epithelial cells SAECs generation l0 l2 and A549 cells model cell line of alveolar type II cells in culture would enhance NO gas phase release. Methods Confluent monolayers of SAECs and A549 cells were cultured in Transwell plates and SAECs were allowed to .
