摘要: 采用实时定量反转录多聚酶链反应方法,检测健康对照组及类圆环病毒因子P1感染组的猪外周血单个核细胞中TLRs mRNA的表达。结果表明,病毒感染后3 d,除TLR2和TLR10外,其余TLRs mRNA表达皆下调。此后不同时相感染组的TLRs mRNA表达水平基本都处于恢复、上调地位。具有明显变化的表现为感染后第24天和第40天,TLR2 mRNA的表达显著上调(P<0.05);此外,感染后第31天和第40天的TLR9 mRNA表达也呈现上调趋势(P<0.1)。结果提示,TLR2和TLR9介导的炎性反应可能在P1识别及其致病机制中起重要作用。

Abstract: The transcriptional levels of Toll-like receptors(TLRs)in peripheral blood mononuclear cells(PB-MCs)from piglets were detected by real-time RT·PCR.The results showed that mRNA levels of most TLRs, except TLR2 and TLRl0, were down·regulated at 3 days post-inoculation(DPI).Whereas the expression levels of TLR2 at 24 and 40 DPI were significantly higher in piglets with P1 infection than that in healthy controls(P<0.05);TLR9 mRNA expression at 3 1 and 40 DPI showed an upward trend(P<0.1).These results suggest that the inflammation reac·tion mediated by TLR2 and TLR9 might play an important role in recognizing P1 and participating in the pathogenesis of P1.
