The paper was published in Proceedings of the National Academy of Sciences. In that study, researchers showed that a calcium triggered chloride channel is quite significant in cutting down two biological processes which contribute to the asperity of asthma. These channels influence airway secretions as well as smooth muscle contraction that are two important factors which might lead to asthma.
Jason Rock, the senior author told that if they could inhibit both these processes by barring this one channel, then they might affect the 2 asthma symptoms. He added that people who suffer from asthma shows a superabundance of mucus with hyper contractility of smooth muscle that makes it tough to move in air and out. A whole lot of people compare that with breathing with a straw.
