Like all viral pathogens, severe acute respiratory syndrome
coronavirus 2, or SARS-CoV 2, requires a cell surface receptor in
order to invade a given host cell. For SARS-CoV 2, this receptor is
actually the enzyme Angiotensin Converting Enzyme 2, or ACE2. ACE2
is responsible for downregulation of the
Renin-Angiotensin-Aldosterone System by deactivation of Angiotensin
II. Explain the RAAS in detail, including the roles played by
kidneys and the lungs, and then explain what effects using
recombinant human ACE2, or rhACE2,...
