| 摘 要： | 利用ST细胞研究了甘草酸对猪呼吸道冠状病毒(PRCV)体外复制过程中的抑制作用。通过RT-PCR和Western blot检测发现甘草酸能有效抑制PRCV的体外复制而对ST细胞不引起明显细胞毒作用。抑制效果与甘草酸的剂量成正比关系。PRCV病毒核衣壳蛋白的表达无论在mRNA水平还是在蛋白质水平均随着甘草酸添加量的增加而降低,提示甘草酸是一种有效的抗PRCV药物。

| Abstract: | The inhibitory effect of glycyrrhizin (GL) on porcine respiratory coronavirus (PRCV) replication was investigated in vitro in ST cells using RT-PCR and Western blot techniques.GL effectively suppressed PRCV replication without causing apparent cell cytotoxicity in ST cells.The inhibitory effect of GL on PRCV was in a dose-dependent manner.The expression levels of both mRNA and protein of the PRCV nucleocapsid protein in ST cells were impeded by the increasing addition of GL,suggesting it is a potential effective antiviral component against PRCV in vitro. |
