Hence, in order to treat ACE-2-mediated COVID-19, there are two primary approaches suggested to restore ACE/ACE2 balance in the literature: (i) ACE inhibitors/increasing ACE2 or Ang (1–7) levels, and/or (ii) seeking new molecules targeting the S protein or ACE2 receptor to prevent infection by SARS-CoV-2 [40,41,42]. The gene discussed is ACE2; the disease is COVID-19.
