Study finds inhibitor for COPD lung destruction

Newly published observations in patients and experiments in mice provide evidence that cigarette smoke reduces expression of the protein NLRX1 in the lung, taking the restraints off a destructive immune response that results in COPD. The researchers hope that pinpointing the protein’s role could lead to improved COPD risk assessment, diagnostics, and treatment. ... Full story
