Research in brief

Airway response mechanism in asthma investigated

A mechanism that helps explain how airways respond to constriction in asthma has been identified by Harvard School of Public Health (HSPH) researchers. The discovery strengthens the basic science known about a disease that affects an estimated 17 million Americans, and also introduces a previously unrecognized means by which physical changes outside the cell can affect cell behavior. The finding was described in the May 6 issue of Nature.
