Dry airways may not only play a central role in the development of the inherited lung disease cystic fibrosis, but also in much more common acquired chronic lung diseases such as asthma and smoker’s lung, the cigarette smoke-induced chronic obstructive pulmonary disease (COPD). This is the conclusion reached by scientists at Heidelberg University Hospital under the direction of Assistant Professor Dr. Marcus Mall from the Department of Pediatrics at Heidelberg University Hospital and Professor Dr. Richard Boucher of the University of North Carolina at Chapel Hill. In animal studies, they found that insufficient hydration of the airway surfaces leads to pathologies typical of chronic obstructive lung diseases in humans.

Thus, these findings point to a new approach for the treatment of these diseases
