Lung-on-a-Chip Reveals How Asthma Attacks Permanently Change Airways

Researchers have engineered a miniature lung tissue in the laboratory and induced an asthma attack within it—revealing how these attacks cause permanent changes to airways. According to Nautilus, the lung-on-a-chip model demonstrates that asthma's effects extend beyond temporary swelling or inflammation. Instead, attacks appear to structurally remodel the airways themselves. Understanding how asthma causes these lasting changes could help scientists develop treatments that prevent or reverse long-term airway damage.
