目的:研究自身免疫调节因子(Aire)对巨噬细胞极化的影响。方法:分别用LPS、IL-4以及LPS联合免疫复合物刺激小鼠单核巨噬细胞系RAW264.7细胞、稳定表达GFP-Aire的RAW264.7细胞(A33-3)细胞和稳定表达GFP的RAW264.7细胞(C1-6),使其向M1(LPS)、M2a(IL-4)和M2b(LPS联合免疫复合物)型巨噬细胞极化。通过Real-time PCR检测各组细胞中M1型巨噬细胞特征分子IL-1α、i NOS和IL-6,M2a型特征分子Arg-1和M2b型特征分子IL-10的表达水平,研究Aire对各种类型巨噬细胞极化的影响。结果:LPS在0.5μg/ml浓度时,RAW264.7细胞中M1型巨噬细胞产物IL-1α、i NOS和IL-6基因表达量最高;而IL-4以及LPS联合免疫复合物的刺激作用有显著的剂量依赖性,都在浓度最高时RAW264.7细胞中Arg1(M2a)和IL-10(M2b)基因表达量最高。LPS刺激后,A33-3细胞中IL-1α和i NOS表达水平明显高于C1-6细胞,IL-6则相反;IL-4及LPS联合免疫复合物刺激后,A33-3细胞中Arg1和IL-10的表达水平明显低于C1-6细胞。结论:Aire可能促进巨噬细胞向M1极化,同时抑制其向M2a和M2b极化。
