CU School Of Medicine researchers offer new target for treating asthma

Researchers have found a potential new for treating , according to a study led by researchers at the University of Colorado School of Medicine at the Anschutz Medical Campus and published in the journal .

About 10 million Americans and more than 300 million people worldwide have asthma. The most common therapies now used with address airway muscle contractions triggered by inflammation, but those treatment results are often temporary or incomplete.

In the article in Nature Communications, , PhD, associate professor of medicine at the , and his co-authors propose targeting other factors related to the overproduction of mucus, an often overlooked factor that causes breathing problems associated with asthma.

Specifically, Evans and his colleagues found that the protein Mucin 5AC (Muc5ac) plays a critical role in airway hyperreactivity, a characteristic feature of asthma that makes it difficult to breathe. In experiments with mice, the scientists found that genetic removal of Muc5ac eliminated airway hyperreactivity.

“The role of mucus as a cause of asthma has been misunderstood and largely overlooked,” Evans said. “We found that it is a potential target for reducing obstruction in asthma.”
