MME and COVID-19: This idea is further supported by substantially decreased expression of peptidase neprilysin, otherwise known as neutral endopeptidase in the same COVID‐19 patient samples (Garvin et al., 2020), since this peptidase also degrades and inactivates bradykinin and substance P (Scholzen & Luger, 2004; Skidgel & Erdos, 2004).
