Protein Associated with Allergic Response Causes Airway Changes in Asthma Patients

Changes that occur in the airways of asthma patients are in part caused by the naturally occurring protein interleukin-13 (IL-13) which stimulates invasion of airway cells called fibroblasts, according to a study conducted by researchers at Duke University. The study is the latest effort by researchers to better understand the processes that are involved in airway remodeling that can cause breathing difficulties in patients with asthma.
