topicNAC Respiratory Infection Meta-Analysis
claimMuco-obstructive lung diseases, such as chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF), and bronchiectasis, are characterized by the accumulation of highly viscoelastic mucus that compromises mucociliary clearance and fosters infection and inflammation.
