& Veesler, D. Structural insights into coronavirus entry. We demonstrate that this strategy is applicable to other β-coronaviruses, such as SARS-CoV and MERS-CoV, and might become an important tool for structural biology, serology, vaccine design and immunology studies.In the past two decades, three zoonotic coronaviruses crossed the species barrier to cause severe pneumonia in humans: (1) severe acute respiratory syndrome coronavirus (SARS-CoV), which was associated with an epidemic in 2002–2003 and a few additional cases in 2004 (refs. Finally, we observed comparable dose-dependent binding of the S309 neutralizing antibody to SARS-CoV 2P DS S and SARS-CoV 2P S, validating retention of antigenicity of the designed construct (Fig. Xiong, X. et al.
