Lung-damaging molecule identified in higher concentrations in cystic fibrosis patients during symptom flare-ups

A molecule previously linked to lung injuries in factory workers producing microwave popcorn might play an important role in microbial infections of the lung suffered by people with cystic fibrosis (CF), according to a recent study led by San Diego State University postdoctoral researcher Katrine Whiteson. The molecule, known as 2,3-butanedione or diacetyl, can be detected in higher concentrations in CF patients than in healthy ones.
