The S protein from coronavirus can bind to the receptors of the host to facilitate viral entry into target cells31,32. Although there are four amino acid variations of S protein between 2019-nCoV and SARS-CoV, 2019-nCoV can also bind to the human angiotensin-converting enzyme 2 (ACE2), the same host receptor for SARS-CoV, as 2019-nCoV can bind to the ACE2 receptor from the cells from human, bat, civet cat, and pig, but it cannot bind to the cells without ACE211,33–35. A recombinant ACE2-Ig antibody, a SARS-CoV-specific human monoclonal antibody, and the serum from a convalescent SARS-CoV-infected patient, which can neutralize 2019-nCoV, confirmed ACE2 as the host receptor for 2019-nCoV36–39. The high affinity between ACE2 and 2019-nCoV S protein also suggested that the population with higher expression of ACE2 might be more susceptible to 2019-nCoV40,41. The cellular serine protease TMPRSS2 also contributed to the S-protein priming of 2019-nCoV, indicating that the TMPRSS2 inhibitor might constitute a treatment option36."}
