【目的】确定蜱传脑炎病毒(Tick-born encephalitis virus,TBEV)对人单核细胞的感染性及对其复制增殖的影响。【方法】用蜱传脑炎病毒感染单核细胞THP-1,观察细胞病变情况。取不同时间点的细胞培养上清,测定病毒滴度,并用Real Time RT-PCR方法检测病毒核酸;用流式细胞法检测细胞感染率,以确定TBEV在THP-1细胞中的复制增殖情况;同时进行细胞活力检测,以确定TBEV感染后THP-1细胞的变化。【结果】TBEV病毒感染THP-1细胞后,可进行复制增殖,流式细胞法可检测到细胞内的病毒,感染病毒后的单核细胞活力显著降低。【结论】TBEV可在单核细胞THP-1中复制增殖,并可造成细胞活力的显著降低,提示单核细胞可能在TBEV感染机体并扩散至各组织器官过程中发挥了重要作用。
