摘要
目的 用基因微矩阵技术研究胸腺肽α1作用于人外周血淋巴细胞后 ,细胞内与抗感染相关的信号转导分子的基因表达谱变化。方法 取正常外周血 6 0 0ml分离淋巴细胞 ,实验组加Tα1(0 .1μg/ml)刺激 ,对照组不加Tα1。培养 4 8h后 ,收获细胞、抽提细胞总RNA并纯化mRNA。逆转录反应将对照组和实验组的cDNA分别标记上荧光分子Cy3和Cy5 ,与信号转导表达谱基因微矩阵杂交后激光扫描、图像分析。结果 筛选出 6 1种Cy5 /Cy3比值大于 2或小于 0 .5的差异表达基因 ,其中与感染相关的有CAML ,PI3 K ,TSP2 ,HM 74 ,PIAS ,PTP ,PSTP等 7种基因表达上调 ,MEK2 ,MAP3K ,Lok等 3种基因表达发生下调。结论 Tα1的直接抗感染作用与这些信号转导分子的基因表达变化有关。
