PROTEIN LEAK DISCOVERY MAY ENHANCE TREATMENT FOR LUNG DISEASES
The researchers discovered that people with asthma and chronic obstructive pulmonary disease (COPD) have a protein in their lungs that leaks a small molecule into their bloodstream that restricts their breathing instead of relaxing their airways. The findings will help clinicians diagnose and determine the severity of chronic lung diseases and make bronchodilators more effective....
