ACE2 and infection: Cells in ENC conditions showed significant reductions in SARS-CoV-2 pv infection compared to control infected cells (cells + SARS-CoV-2 pv): 1.37 ± 0.28% (p = 0.007), 1.43 ± 0.26% (p = 0.024) and 0.79 ± 0.17% (p = 0.002) infected cells for cells + (ENC + SARS-CoV-2 pv), cells + (ENC + ACE2 + SARS-CoV-2 pv) and cells + (ENC + IgG + SARS-CoV-2 pv) conditions respectively.
