摘要 目的:探讨可溶性Jagged-1/Fc嵌合蛋白对小鼠淋巴细胞产生细胞因子的影响。方法:不同时间和不同浓度Jagged-1/Fc处理小鼠淋巴细胞,ELISA检测其培养上清中细胞因子的水平,并用Westernblot分析相关蛋白NICD和Del-tex的表达。结果:低浓度Jagged-1/Fc对淋巴细胞生成IL-17无明显影响,但高浓度Jagged-1/Fc(500μg/L)组IL-17的表达量是对照组的64.75倍,并且随着时间的增加而减少;IFN-γ随着Jagged-1/Fc浓度的增加而减少。Westernblot分析显示Jagged-1/Fc处理组的NICD和Deltex的表达明显高于对照组和Anti-Jagged-1组。结论:高浓度Jagged-1/Fc能够诱导淋巴细胞表达IL-17,可能在指导初始T细胞向Th17细胞偏离中发挥作用。
