Asthma sufferers have trouble breathing because of the narrowing of the airways in their lungs, an example of which is shown in the upper left. In chronic asthma (lower left), repeated cycles of inflammation, damage, and repair lead to airway remodeling and fibrosis, the buildup of collagen and other materials. A signaling molecule known as NF-κB can significantly reduce chronic asthma (lower right). Image credit: National Institute of Allergy and Infectious Diseases.
