目的  觀察在小鼠內(nèi)源性損傷模型下肝臟Kupffer細(xì)胞(Kupffer cell,KC)和肝竇內(nèi)皮細(xì)胞(sinusoidal endothelial cells,SEC)表面Toll樣受體2(TLR2)蛋白及mRNA表達(dá)。
方法  在肝部分缺血-再灌注損傷模型下,采用原位灌注消化法分離并純化KC和SEC,用大鼠抗小鼠TLR2 IgG和異硫氰酸熒光素(FITC)的二抗進(jìn)行染色,流式細(xì)胞儀(FCM)測(cè)定陽性細(xì)胞數(shù),并用實(shí)時(shí)定量PCR(RealTime RT-PCR)檢測(cè)兩種細(xì)胞中TLR2 mRNA含量。
結(jié)果  損傷組KC TLR2的表達(dá)明顯高于假手術(shù)組,蛋白質(zhì)表達(dá)為(9.19±1.07)% vs (1.52±0.21)%, P<0.01; mRNA表達(dá)為0.54±0.77 vs 2.62±2.19, P<0.05。SEC差異并無顯著性意義。
結(jié)論  在肝缺血-再灌注損傷中,小鼠肝KC TLR2在蛋白質(zhì)和mRNA水平的表達(dá)明顯增高。
