Drugs limiting excess mucus could save lives

Respiratory conditions that restrict breathing such as asthma and chronic obstructive pulmonary disease (COPD) are common killers worldwide. But no effective treatments exist to address the major cause of death in these conditions — excess mucus production. Now, Washington University researchers have described the molecular pathway responsible for excess mucus in airway cells and have used that information to design a series of new drugs that inhibit that pathway.
