Maryland, Oct 25 (THAINDIAN NEWS) A new research by researchers from the University Of Maryland School Of Medicine in Baltimore has revealed that the human lungs and airways also contain bitter receptors.

The research which was published online in the journal Nature Medicine reveals that the receptors relax when they are exposed to bitter tastes and scientists are hopeful this is going to improve the chances of finding a long term treatment for conditions like Asthma and other conditions.

A lung expert, Dr. Stephen B. Liggett indicated that the result of the study was shocking to him because he expected the bitter taste receptors to cause undesirable effects in the body. He said he expected the receptors to cause cough and chest tightness in people and the behavior that was recorded in the new study was not expected by him.

Michael J. Welsh of the University of Iowa reported last year that the cilia contain bitter taste receptors and that led to the current study.

The difference between the taste bud in the mouth and that of the lungs is the way they react to bitter taste. While the taste bud in the mouth sends signals to the brain, the receptors in the airways react to the taste and do not send any signal to the brain.
