Washington: Chronic Obstructive Pulmonary Disease (COPD) caused by excessive smoking is characterized by blockage or narrowing of airways in the lungs.Researchers identified the protein SAA as playing a key role in chronic inflammation and lung damage in COPD and also in inhibiting the natural effort of the lung to repair itself after smoking has stopped.Gary Anderson, professor at the University of Melbourne, said the discovery could help improve lung function at any stage of COPD."It has the potential to dramatically improve the lives of many people suffering these conditions and reduce the huge burden of health and hospital costs associated with their treatment," he said.
