An unexpected discovery of taste receptors in lungs may provide asthma sufferers with more effective ways to restore free breathing during attacks, researchers at the University of Maryland School of Medicine reported Sunday.

Experiments with mice and human tissues revealed that the receptors, like those found on the tongue, respond to bitter substances by signaling constricted muscles in the lungs to relax, reopening tight airways in seconds.
