SARS-CoV-2 RNA levels, IFN-1, ISGs, and NF-κB gene responses within the respiratory tract of mild and severe COVID-19 patients

Researchers characterized the expression of IFN-1 and IFN-2, ISGs, and NF-κB in the upper respiratory tracts of patients with mild and severe COVID-19, to understand innate immune responses to SARS-CoV-2 infections.
