Expression of Toll-like Receptor 2/4 on Alveolar Macrophage in the Model of Total Hepatic Ischemia/Reperfusion Injury in Mice

客观：在鼠标在全部的肝的局部缺血的进程期间在牙槽的巨噬细胞探索像使用费的受体 2/4 的表达式和意思。方法：BALB/c 老鼠在全部的肝的 ischemia/reperfusion 的一个模型被使用。牙槽的巨噬细胞被 bronchoalveolar 洗室年龄(BAL ) 的工具在 1h， 6h 和 12h 的时间点收集，并且它的 TLR2/4 mRNA 和蛋白质与流动血细胞计数和实时 PCR 被检测。在 BAL 液体的 TNF 的水平我们 remeasured。军邮局的集中，比率湿 / 干燥并且肺组织学的分数被用来估计肺损害的度。结果：在肝的 ischemiareperfusion 的三个次点， TLR2/4 蛋白质和 mRNA 的表示是起来调整的并且在上升的 TLR2was 的水平不断地。TLR4 在 6 h 的时候到达了山峰价值(P 【 0.01 ) 。在 BAL 液体的水平 ofTNF-2 在 6 h 的时候到达了最高的点(P 【 0.01 ) 。wet/dryrose 的比率不断地在肝的局部缺血灌注期间。在 1 h 以后，军邮局的水平很快增加了。然后，它在 6 h 的时期期间到达了山峰价值到 12 h。结论：牙槽的巨噬细胞的老鼠上的 TLR2/4 在肝的 ischemia/reperfusion 的过程被激活并且在肺的损害包含了。

Objective： To explore the expression and meaning of Toll-like receptor 2/4 in alveolar macrophage during the process of total hepatic ischemia in mice. Methods： BALB/c mice were used in a model of total hepatic ischemia/reperfusion. Alveolar Macrophage were collected at the time point of lh, 6h and 12h by the means of bronchoalveolar lavage （BAL）, and its TLR2/4 mRNA and protein were detected with Flow Cytometry and Real-time PCR. The level of TNF in BAL fluid were measured. The concentration of MPO, the ratio of wet/dry and lung histological scores were used to assess the degrees of lung injuries. Results： At the three time points of hepatic ischemia reperfusion, the expression of TLR2/4 protein of and mRNA were up-regulated and the level of TLR2 was on the rise continually. TLR4 at the time of 6 h reached the peak value （P〈0.01）. The level of TNF-2 in BAL fluid reached the highest point at the time of 6 h （P〈0.01）. The ratio of wet/dry rose continually during hepatic ischemia reperfusion. After 1 h, the level of MPO increased rapidly. Then it reached the peak value during the period of 6 h to 12 h. Conclusion： TLR2/4 on the mice of alveolar macrophage were activated in the process of hepatic ischemia/reperfusion and involved in the injury of lung.
