Taste Buds in Lungs Could Lead to New Asthma Treatments

It turns out that taste buds don’t only reside on your tongue -- they’re also in your lungs. And when you lungs' taste receptors encounter bitter substances, your airways open up and aid in breathing.

This discovery could lead to new treatments for asthma sufferers.

AOL Health reports:

“The researchers performed experiments on mice, barraging their lung receptors with bitter-tasting compounds. The researchers assumed that exposure to bitter substances would cause a tightening of the airways, but, in fact, the opposite proved to be true. The airways responded by opening up, which could ease breathing and potentially help in the treatment of other lung diseases.”

Asthma affects 23 million people in the United States.
