World Trade Center firefighters: Lung injury resistance biomarkers

Date: Sep 11, 2019

Author: Steve Down

Some New York firefighters who attended the World Trade Center collapse in 2001 have a known resistance to lung injury and their serum metabolome has been studied by US scientists to try and identify the components responsible, which could be valid therapeutic targets.
