From the authors: “The data presented here document that elevated [fraction of inspired oxygen] increased expression of TMPRSS2 and TMPRSS11D, which are required for efficient viral entry of SARS-CoV-2.” 

This study is highlighted as one of November’s "best of the best" as part of the American Physiological Society's APSselect program.
