What Is a Lung Receptor?

Lung bitterness receptors are receptors that resemble tongue taste buds in the human lung, but can only sense bitterness. Based on this finding, scientists believe that this holds promise for treating diseases such as asthma. Using bitter stimuli to stimulate lung receptors can more fully open the constricted lung airways than existing drugs. New research by American scientists has shown that the human lung can "identify" bitterness in a manner similar to how tongue taste buds distinguish tastes. The taste receptors in the lungs are similar to the tongue, but they do not exist in clusters and do not send any signals to the brain.
