【摘要】目的觀察供肝轉染IL-10后基因表達情況。
方法應用改良“二袖套法”行Lewis到BN大鼠肝移植11例,然后分為對照組3例; 空載體轉染組4例,術中供肝冷保存期門靜脈注射Lipofectamine 2000-pCR3.1空載體質粒復合物,保存45 min后行肝移植; 重組IL-10(rIL-10)轉染組4例,術中供肝冷保存期門靜脈注射Lipofectamine 2000-pCR3.1 rIL-10復合物,保存45 min后行肝移植。術后第6天處死全部大鼠,取血清檢測IL-10水平,另取肝組織行免疫組化染色和RT-PCR檢測肝細胞IL-10表達水平。
結果rIL-10轉染組血清IL-10水平明顯升高,肝上下腔靜脈IL-10水平可達(639.27±67.11) pg/ml,是肝下下腔靜脈IL-10水平的近1.4倍(P=0.024); 免疫組化染色結果示肝細胞胞槳呈棕黃色或深棕色,而其他兩組肝細胞著色輕微或不明顯。肝組織RT-PCR顯示,IL-10 mRNA的表達在rIL-10轉染組明顯處于高水平(P=0.000)。
結論脂質體介導,體外冷保存期經門靜脈途徑進行供肝轉染IL-10,可以使IL-10在肝臟獲得較高水平的表達。
