A novel betacoronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which caused a large respiratory outbreak in Wuhan, China in December 2019, is currently spreading across many countries globally. Here, we show that a TMPRSS2-expressing VeroE6 cell line is highly susceptible to SARS-CoV-2 infection, making it useful for isolating and propagating SARS-CoV-2. Our results reveal that, in common with SARS- and Middle East respiratory syndrome-CoV, SARS-CoV-2 infection is enhanced by TMPRSS2.
一种新型的β冠状病毒，即严重急性呼吸综合征冠状病毒 2（SARS-CoV-2），于 2019 年 12 月在中国武汉引发了大规模呼吸道疫情，目前正在全球许多国家蔓延。在这里，我们表明，表达 TMPRSS2 的 VeroE6 细胞系对 SARS-CoV-2 感染高度敏感，使其可用于分离和繁殖 SARS-CoV-2。我们的结果表明，与 SARS-CoV 和中东呼吸综合征-CoV 一样，SARS-CoV-2 感染可被 TMPRSS2 增强。
