摘要 目的:比较HSPgp96与LPS对巨噬细胞免疫功能的激活作用。方法:培养小鼠腹腔巨噬细胞,分组用PBS、HSPgp96和LPS诱导后,在不同时间用酶法测定NO生成量。按效靶比10:1加入H22肝癌细胞,24h后靶细胞进行单细胞凝胶电泳,染色观察。在不同时间用激光扫描共聚焦显微镜观测巨噬细胞MHC-Ⅱ和CD86的表达。结果:LPS和HSPgp96促进巨噬细胞NO生成的作用相当,并随作用时间延长而增加。巨噬细胞攻击后的靶细胞呈现DNA损伤后的彗星现象。LPS和HSPgp96均促进巨噬细胞MHC-Ⅱ和CD86的表达,但HSPgp96诱导组表达更快更强。结论:与LPS相比,HSPgp96活化小鼠腹腔巨噬细胞细胞毒活性的作用相当,而诱导抗原提呈功能的作用更强。
