ACE2 and COVID-19: Although several studies have already shown that protease inhibitors such as polyphenolic compounds can be very effective in controlling virus‐induced infections (Liu et al., 2008, 2020; Mohammadi & Shaghaghi, 2020; Shaghaghi, 2020; Yang et al., 2020b), so far, there is not enough evidence from in vivo studies reporting the associations between polyphenols and downregulation of ACE2 expression related to COVID‐19.
