    Snippet: Studies of SARS coronavirus (SARS-CoV)—the causative agent of severe acute respiratory syndrome (SARS)—have been hampered by its high transmission rate and the pathogenicity of this virus. To permit analysis of the host range and entry mechanism of SARS-CoV, we incorporated the humanized SARS-CoV spike (S) glycoprotein into HIV particles to generate a highly infectious SARS-CoV pseudotyped virus. The infection on Vero E6—a permissive cell line to SARS-CoV—could be neutralized by sera fro
    Document: Studies of SARS coronavirus (SARS-CoV)—the causative agent of severe acute respiratory syndrome (SARS)—have been hampered by its high transmission rate and the pathogenicity of this virus. To permit analysis of the host range and entry mechanism of SARS-CoV, we incorporated the humanized SARS-CoV spike (S) glycoprotein into HIV particles to generate a highly infectious SARS-CoV pseudotyped virus. The infection on Vero E6—a permissive cell line to SARS-CoV—could be neutralized by sera from convalescent SARS patients, and the entry was a pH-dependent process. With these highly infectious SARS-CoV pseudotypes, several cell lines derived from various tissues were revealed as susceptible to SARS-CoV, which were highly corresponding to the expression pattern of virus’s receptor angiotensin-converting enzyme 2 (ACE2). In addition, we also demonstrated angiotensin 1 converting enzyme (ACE)—the homologue of ACE2 could not function as a receptor for SARS-CoV.
