“…According to new findings, the SARS-CoV-2 spike (S) glycoprotein of SARS-CoV-2 interacts with angiotensin-converting enzyme-2 (ACE2) and cellular protease transmembrane protease serine-2 (TMPRSS-2) as internalization receptors to enter host cells during the infection cycle. Downregulation of ACE2 by SARS-CoV-2 causes a reduction in ACE2 products such as Ang- [1] , [2] , [3] , [4] , [5] , [6] , [7] , Ang [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , apelin [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , and accumulation of substrates such as apelin [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] and Ang II [82] . ACE2 downregulation correlates with systemic RAS imbalance and facilitates the development of multiorgan damage from SARS-CoV-2 infections [83] .…”
