Study sheds new light on asthma, COPD

In cells lining the airway, high levels of certain proteins have long been linked with the overproduction of mucus characteristic of diseases like asthma and COPD. New research from the School of Medicine provides clues to potentially counteract inappropriate mucus production.

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.
