In the case of SARS, apoptosis was observed in patients' lung epithelial cells; thus, SARS-CoV induced apoptosis would certainly have a deleterious pathogenic role, leading to severe tissue damage [26] . This model system allowed us to avoid possible secondary effects resulting from viral replication or infections in vivo and to directly test whether SARS-CoV spike protein might adversely affect acute lung injury through modulation of ACE2. SARS-CoV infection or spike protein treatment can down-regulate the expression of ACE2, and thus aggravate lung injury. Nabel, pH-dependent entry of severe acute respiratory syndrome coronavirus is mediated by the spike glycoprotein and enhanced by dendritic cell transfer through DC-SIGN ./cache/cord-271505-eot38721.txt ./txt/cord-271505-eot38721.txt
