Dig Dis Sci:丙型肝炎病毒进入巨噬细胞/单核细胞主要取决于巨噬细胞的吞噬作用

2019-06-10 不详 MedSci原创

丙型肝炎病毒(HCV)是一种嗜肝性病原体病毒,肝细胞是HCV感染的靶细胞。越来越多的研究表明,一些非肝细胞也支持HCV进入和复制,比如巨噬细胞。目前,HCV进入巨噬细胞的机制尚不清楚。本研究旨在探究HCV进入巨噬细胞的机制。

背景
丙型肝炎病毒(HCV)是一种嗜肝性病原体病毒,肝细胞是HCV感染的靶细胞。越来越多的研究表明,一些非肝细胞也支持HCV进入和复制,比如巨噬细胞。目前,HCV进入巨噬细胞的机制尚不清楚。本研究旨在探究HCV进入巨噬细胞的机制。

方法
研究人员使用HCV RNA转染的Huh7细胞制备感染性HCV颗粒(HCVcc)。通过siRNA转染获得CD81敲除细胞。通过RT-qPCR测定HCV RNA水平。流式细胞术分析用于确定CD11b,CD68和CD81的细胞表达水平。进行ELISA和蛋白质印迹以定量IL-1β,IL-6和TNF-α的蛋白质水平。通过中性红摄取测定法测定吞噬能力。

结果
CD81敲除不能抑制HCVcc进入巨噬细胞。来自慢性丙型肝炎患者血清的合并IgG不能阻止HCV进入巨噬细胞。源自THP-1细胞的巨噬细胞显示出更强的吞噬能力,其吞噬更多的HCV RNA。用内吞抑制剂甲基-β-环糊精处理巨噬细胞减少了HCV的内化。巨噬细胞对HCV的摄取与F-肌动蛋白细胞骨架的重组和PI3Ks活化有关。HCV感染显着增加巨噬细胞中IL1β和IL6的表达,促进巨噬细胞的凋亡。

结论
HCV进入巨噬细胞主要取决于巨噬细胞的吞噬作用。
