Epigenetic modifiers has been showed to rescue F508del-CFTR channel to apical membrane of epithelial cell lines. In this study, the investigators evaluate epigenetic modifiers effects firstly on CFTR rescue, then on secretion and synthesis of inflammatory factors (IL-8, LXA4 and SCGB1A1) and mucines (MUC5AC and MUC5B) in a dynamic epithelium model using an air-liquide interface culture of nasals cells from CF patients or controls.
