Le transport de Na+ par ENaC et de Cl- par CFTR, dans l’épithélium des voies aériennes (VA), contrôle la clairance mucociliaire en modulant le volume du liquide de surface (ASL). L’expression et la fonction de ces canaux peuvent être modifiées au cours des maladies inflammatoires chroniques des VA. Dans un modèle de culture primaire de cellules épithéliales nasales humaines (CENH), nous avons démontré l’existence, au cours de la polypose nasosinusienne, d’une chute de la sécrétion de Cl- par CFTR dont l’expression est diminuée par le TGFß1, cytokine de l’inflammation. Nous avons ensuite étudié l’effet de l’élastase, et de son inhibiteur l’EPIhNE4 sur la fonction d’ENaC dans des CENH de patients atteints ou non de mucoviscidose (CF) où l’hyp...
