摘要(Abstract)：

目的探讨柔嫩艾美耳球虫(E.tenella)诱导鸡巨噬细胞Toll样受体(Toll-like receptors,TLRs)m RNA转录水平的变化。方法用有病毒和无病毒E.tenella分别刺激鸡巨噬细胞,于刺激后0、1、2、4、6、8 h收集鸡巨噬细胞,Trizol试剂提取总RNA,经q RT-PCR法检测鸡Toll样受体(chicken TLRs,Ch TLRs)表达的动态变化。结果有病毒E.tenella刺激鸡巨噬细胞的Ch TLR1和Ch TLR21 m RNA的转录水平于刺激4 h时达最高,Ch TLR4、Ch TLR7、Ch TLR15 m RNA的转录水平于刺激2 h时达最高,Ch TLR2、Ch TLR3、Ch TLR5 m RNA转录水平于刺激4 h后显著下调,与对照组比较,差异均有统计学意义(P<0.05)。无病毒E.tenella刺激鸡巨噬细胞各时间点的Ch TLR1、Ch TLR4、Ch TLR21 m RNA的转录水平与对照组差异均无统计学意义(P>0.05);Ch TLR15 m RNA的转录水平于刺激2 h时达最高,Ch TLR2、Ch TLR3、Ch TLR5、Ch TLR7 m RNA转录水平于刺激4 h后显著下调,与对照组比较,差异均有统计学意义(P<0.05)。结论 Ch TLR7和Ch TLR21可能与鸡的抗E.tenella病毒的先天性免疫应答有关,为E.tenella感染的天然免疫机制的研究及鸡E.tenella病的防控奠定了基础。
