Angiotensin Converting Enzyme 2 (ACE2)
ACE2 is one of the key receptors for SARS-CoV invasion of the human body [32]. Researchers found that SARS-CoV-infected or recombinant wild-type SARS-spike protein-treated mice displayed significantly reduced ACE2 expression in the lung. It has also been shown that the latest outbreak of coronavirus pneumonia (2019-nCoV, SARS-CoV-2) is invading human alveolar epithelial cells and is therefore, could be screened against 2019-nCoV, suggesting further studies [33].
