摘要:

目的:探索4-苯乙烯磺酸马来酸酐共聚物(PSM)对单纯疱疹病毒Ⅱ型(HSV-2)感染细胞或小鼠的抑制作用。方法:建立Vero-ICP10细胞系,通过Luciferase检测不同浓度PSM对HSV-2感染细胞的抑制,并通过In cell western技术检测HSV-2 gD蛋白表达,确定PSM浓度与HSV-2感染间的关系;建立HSV-2阴道感染小鼠模型,观察PSM抑制HSV-2经生殖道感染小鼠。结果:Luciferase实验和In cell western实验结果均表明PSM具抗HSV-2感染细胞的作用;小鼠模型中,5%浓度的PSM能有效防止小鼠感染HSV-2(p<0.001)。结论:PSM在体内和体外模型上均可以抑制HSV-2感染。

Objective: To investigate the antiviral effect of polymer of styrenesulfonic acid and maleic acid, (4-styrenesulfonic acid-co-maleic acid) (PSM) against herpes simplex virus type 2 (HSV-2). Methods: A Vero-ICP10 cell line containing virus-controlled Luciferase as indicator was established for analyzing the effect of different concentrations of PSM on HSV-2 infection. An In cell western assay was also used for detecting intracellular viral protein expression. PSM inhibitory activity was further evaluated in a HSV-2 vaginal challenge murine model. Results: The results of in vitro analyses showed that PSM could protect cell from HSV-2 infection, and the murine model showed that 5% PSM protected 95% of the animals from HSV-2 infection ( P < 0.001). Conclusion: PSM is a potential agent for the prevention of HSV-2 infection through sexual route.
