Vero E6 细胞通常用于严重急性呼吸综合征相关冠状病毒 (SARS-CoV) 的体外研究和抗病毒评估目的。更好地了解 Vero E6 细胞中 SARS-CoV 的生长动力学对于帮助阐明选择性抗病毒药物的抗病毒活性机制至关重要。在这项研究中,通过定量感染后不同时间点的细胞内和细胞外病毒RNA载量以及细胞外病毒产量,研究了Vero E6细胞中SARS-CoV的生长动力学。感染后12小时,细胞内病毒RNA载量比感染时高3×102倍,细胞外病毒RNA载量增加2×103倍。感染后6小时,细胞内病毒RNA水平开始上升。一小时后(感染后 7 小时),细胞外 SARS-CoV RNA 的水平也开始上升。感染后 6 至 7 小时内,感染性后代 SARS-CoV 也首次出现在上清液中,这一事实证实了这一点。感染后 12 小时,上清液中的 SARS-CoV 滴度达到 5.2 × 103 CCID50/ml。
Vero E6 cells are commonly used for in vitro studies of the severe acute respiratory syndrome-associated coronavirus (SARS-CoV) and for antiviral evaluation purposes. A better understanding of the SARS-CoV growth kinetics in Vero E6 cells is crucial to help elucidate the mechanism of antiviral activity of selective antiviral agents. In this study, the growth kinetics of SARS-CoV in Vero E6 cells were studied by quantitation of intra- and extracellular viral RNA load as well as extracellular virus yield at different time points post-infection. At 12 h post-infection, the intracellular viral RNA load was 3 × 102-fold higher than at the time of infection, and the extracellular viral RNA load was increased with a factor of 2 × 103. Intracellular viral RNA levels started to rise at 6 h post-infection. One hour later (at 7 h post-infection), the levels of extracellular SARS-CoV RNA also began to rise. This was corroborated by the fact that infectious progeny SARS-CoV also first appeared in the supernatant between 6 and 7 h post-infection. At 12 h post-infection, SARS-CoV reached titers in the supernatant of 5.2 × 103 CCID50/ml.
