Washington: Researchers have found how environmental irritants, such as air pollution and cigarette smoke, trigger coughing.
In a study conducted by experts from Imperial College London and the University of Hull, it was found that irritants activate receptor proteins called TRPA1 on the surface of nerve endings in the lungs.
Subsequently, sensory nerves trigger a cough reflex.
The researchers insisted that blocking TRPA1 receptors could treat coughing.
Professor Maria Belvisi, co-author of the study from the National Heart and Lung Institute at Imperial College London, said, "For some people, chronic coughing can be annoying and uncomfortable, but for others it can be distressing and can have a severe impact on their quality of life.
