摘要
研究人工培植冬虫夏草水提物对人类巨细胞病毒(HCMV)的抑制作用,并对其抑制机制进行初步研究。通过细胞病变法(CPE)检测虫草水提物的细胞毒性及抗病毒活性,同时采用免疫印迹实验(Western Blot-ting)初步探究虫草水提物抗HCMV的作用靶点。结果表明虫草水提物浓度在0.3 g.L-1以上时能有效抑制HCMV在宿主细胞中的复制,用虫草水提物处理感染的宿主细胞,HCMV的早期立即蛋白IE1、IE2及早期蛋白UL84的表达均明显受到抑制。虫草水提物可作为潜在的抗HCMV药物。
The anti-HCMV effect and its potential mechanism of the water extract from Cordyceps sinensis is investigated.Cytopathic effect (CPE) method is utilized to examine its toxicity to human fore-skin fibroblasts(HFFs) and the anti-HCMV effect in vitro of the water extract.Moreover,westernbolt is used to investigate the mechanism of anti-HCMV effect of the water extract.The results show that the water extract can inhibit HCMV replication effectively at the concentration of 0.3 g·L-1.In HCMV-infected cells,the expression of immediate-early protein IE1、IE2 and early protein UL84 can be inhibited to a large degree when treating with the water extract.
