Cigarette Smoking Linked to Mucus Overproduction in Chronic Bronchitis

March 2011
Pulmonary Reviews;Mar2011, Vol. 16 Issue 3, p14
The article reports on the link of cigarette smoking to the overproduction of mucus in patients with chronic bronchitis. Based on a study, a protein called Bik that naturally kills mucus-producing airway cells in bronchitis patients is being suppressed by cigarette smoke. The study may reportedly lead to the development of therapies that would restore expression of Bik and reduce mucus-producing cells.
