Another confounding factor is cigarette smoking, which has been reported to increase ACE-2 expression in both experimental models and humans. 4. Renin-angiotensin-aldosterone system (RAAS)-interfering drugs are likely to affect ACE-2 receptor-SARS-CoV-2 interaction dynamics within lung, heart, vascular, kidney and gut tissues [5, 19] , while it is still not completely elucidated how such interactions are relevant to the clinical course of cardiovascular comorbidities in patients with COVID-19 [29] . Consequently, the up-regulation of human ACE-2 induced by RAAS-antagonists in SARS-CoV-2-infected patients could be clinically useful, due to the cardiovascular protection elicited by the increased activity of angiotensin(1-7), thereby attenuating angiotensin II effects on vasoconstriction and sodium retention [31, 34] . ./cache/cord-264828-6w13xo2a.txt ./txt/cord-264828-6w13xo2a.txt
