A targeted treatment for emphysema?

Emphysema is a progressive, debilitating lung disease in which the lung’s breathing sacs, or alveoli, enlarge, get thinner, and eventually are destroyed as the cells die off. It can be fatal, and there is currently no cure. New research at Boston Children’s Hospital, using lung cells and mouse models of emphysema, offers hope in the form of a small, engineered peptide molecule called PR1P.
