Discovery of how limiting damage from an asthma attack could stop disease

Scientists at King's College London discovered that limiting damage from an asthma attack could stop the disease by blocking a process that causes epithelial cell death. The findings suggest that preventing this damage could also prevent long-term inflammation, wound healing, and infections in asthma sufferers.
