摘要: 为了探讨红豆杉多糖(TP)抗鸡传染性法氏囊病毒(IBDV)的活性及其作用机制,试验在体外成纤维细胞培养体系上,通过直接灭活、抑制和阻滞三种作用方式评价TP对IBDV B87株感染DF-1细胞的影响。采用细胞病变抑制法和CCK-8对红豆杉多糖进行抗病毒活性检测。结果表明:红豆杉多糖的最大安全浓度为125 μg/mL,在此浓度下,红豆杉多糖对B87株具有一定的直接灭杀作用,预处理1 h的抗病毒效果最佳,但不能有效阻止病毒吸附。说明,红豆杉多糖可通过直接灭活或者阻滞病毒侵入细胞发挥抗病毒作用。

Abstract: In order to investigate the activity of taxus polysaccharides(TP)against chicken infectious bursal disease virus(IBDV)and its mechanism of action, experiments were carried out to evaluate the effect of TP on the infection of DF-1 cells with IBDV B87 strain on an in vitro fibroblast cell culture system by three modes of action: direct inactivation, inhibition, and blockade. The antiviral activity of the taxus polysaccharides was detected by using cytopathic inhibition assay and CCK-8. The results showed that the maximum safe concentration of taxus polysaccharide was 125 μg/mL, at this concentration, taxus polysaccharides had a certain direct inactivation effect on B87 strain, and the best antiviral effect was achieved by pretreatment for 1 h. However, it could not effectively prevent the virus adsorption. This suggests that the taxus polysaccharide can play an antiviral role by directly inactivating or blocking the virus from invading the cells.

Key words: TP, IBDV, immunosuppression, immune regulation
