Cystic fibrosis (CF) is a genetic disease characterized by overproduction of mucus, a consequence of CFTR channel dysfunction. All mucosal surfaces of the human body are affected; however, one of the most damaged organs is the airway. A layer of thick and sticky mucus plugs the airway ducts, resulting in respiratory difficulties and eventually pulmonary failure.
