We investigated the cell types with greatest enrichment for ACE2 and TMPRSS2 in non-infected controls and individuals with influenza A and B. Strikingly, ACE2 was most upregulated in samples from influenza-virus-infected individuals within bystander goblet or squamous cells not directly infected by virus (Figures 6F and 6G). The gene discussed is ACE2; the disease is influenza.
