Interaction Information:

Comment ACE2 functions as a carboxypeptidase, cleaving a single residue from angiotensin I (AngI), generating Ang1-9, and a single residue from angiotensin II (AngII) to generate Ang1-7. The ACE2 homologue ACE, by contrast, cleaves the decapeptide AngI into the octapeptide AngII. Thus, ACE2 counterbalances the function of ACE and negatively regulates AngII production. To test whether Spike-Fc injections indeed affect the function of the renin-angiotensin system, AngII levels in the lungs of acid- and Spike-Fc–treated mice were analyzed. Acid aspiration increased AngII levels in the lungs of wild-type mice. Notably, the authors observed a further, significant increase in AngII levels in the lung tissue of mice treated with Spike-Fc.
