摘要
旨在研究人单纯疱疹病毒2型(HSV-2)潜伏相关转录体(LAT)开放读码框2(ORF2)对体外培养的非洲绿猴肾细胞(Vero)形态和活性的作用。将构建好的带绿色荧光蛋白(EGFP)标签的HSV-2LAT ORF2真核表达载体pEGFP-ORF2,转染vero细胞,荧光显微镜观测细胞形态的改变和MTT法进行活性分析。结果:显示,HSV-2LATORF2诱导细胞形态发生明显变化,绿色荧光蛋白在细胞的定位也发生了改变,细胞活性降低。由此证实,HSV-2LAT ORF2对细胞有损伤作用,为阐明HSV-2LATORF2的功能提供了资料。
It was to explore the effect of HSV-2 LAT ORF2 on cytomorphology and cell activity in vitro. Eukaryotic expressive veetors of EGFP-ORF2 fusion protein named pEGFP-ORF2 was transfected into Vero cells by liposome transfection reagent,morphogenesis were observed by fluorescence microscopy and cell activity were analyzed by MTT. Results that HSV-2 LAT ORF2 had evident change in cytomorphology,the location of fusion protein of EGFP and HSV-2 LAT ORF2 in cells has changed,and MTT analysis revealed the cell activity decreased. Therefore,it proved that HSV-2 LAT ORF2 has impairment on cells, and these results may shed light on the fur ther study of the function of HSV-2.
