在这项研究中,我们使用 EBOV Makona 在黑腹果蝇 Schneider 2 (S2) 细胞中生成了针对丝状病毒科、埃博拉病毒属、扎伊尔埃博拉病毒种、Makona 株 (EBOV) 的重组病毒样颗粒 (VLP)。 S2 细胞与编码 EBOV Makona 蛋白的四种病毒质粒共转染,并通过免疫印迹分析蛋白表达。我们证实 EBOV Makona 蛋白在 S2 细胞中成功表达。此外,我们进一步通过电子显微镜检查了细胞内和细胞外VLP的形成。通过蔗糖梯度超速离心转染 EBOV Makona 基因的 S2 细胞产生 eVLP,并通过免疫印迹分析证实 VLP 的产生。总的来说,我们的研究结果表明,S2 细胞系统可能是有效生产 eVLP 的有前途的工具。
In this study, we generated recombinant virus-like particles (VLPs) against family Filoviridae, genus Ebolavirus, species Zaire ebolavirus, strain Makona (EBOV) in Drosophila melanogaster Schneider 2 (S2) cells using the EBOV Makona. S2 cells were cotransfected with four viral plasmids encoding EBOV Makona proteins and protein expression was analyzed by immunoblotting. We confirmed that EBOV Makona proteins were successfully expressed in S2 cells. Additionally, we further examined the formation of intracellular and extracellular VLPs by electron microscopy. eVLPs were produced by sucrose gradient ultracentrifugation of S2 cells transfected with EBOV Makona genes, and production of VLPs was confirmed by immunoblot analysis. Collectively, our findings showed that the S2 cell system could be a promising tool for efficient production of eVLPs.
