Researchers from Boston University School of Medicine (BUSM) have pinpointed a genetic signature for chronic obstructive pulmonary disease (COPD) from airway cells harvested utilizing a minimally invasive procedure. The findings provide a novel way to study COPD and could lead to new treatments and ways to monitor patient's response to those treatments. The study is published online in the American Journal of Respiratory and Critical Care Medicine. Chronic obstructive pulmonary disease (COPD) is a progressive lung disease that leads to the loss of lung function primarily caused by cigarette smoking. It causes coughing, wheezing, shortness of breath, chest tightness and other symptoms that make it difficult to breathe. While there are treatments and lifestyle changes that can help people cope with COPD, there currently is no cure and there are no effective therapies to reduce the rate of lung function decline. According to the National Institutes of Health's National Heart, Lung, and Blood Institute (NHLBI), which partially funded the study, COPD is the third leading cause of death in the United States, resulting in approximately 135,000 deaths each year.
