细胞连接蛋白在肝星状细胞活化中的作用
发布时间:2021-09-23 14:48
[背景]肝硬化是进展性肝纤维化的终末期,如果不加以预防,可能发展为肝硬化,甚至肝癌和肝衰竭。在肝纤维化的进展过程中起着核心作用的是肝星状细胞(hepatic stellate cell,HSC)的活化。当前的研究主要集中在细胞因子促活化的作用上,已经阐明诸多因子的分子机制,但是对细胞因子活化途径的干预,对于抗纤维化的治疗效果无法达到预期。而细胞间接触和连接是活化后的HSC的重要表现,本课题组之前的研究也发现细胞接触与非接触共培养,HSC会表现出不同的活化状态,因此,肝硬化发病新的机制的探索将有助于肝纤维化的治疗取得突破。[目的]通过将静止的肝星状细胞与活化的肝星状细胞进行接触培养与非接触共培养进行对照,观察细胞间连接蛋白CX-43表达及阻断后对肝星状细胞活化的影响,从而揭示其对HSC活化的作用。[方法]1.通过蛋白酶,胶原酶,后分散液序贯灌注的方法灌注雄性S-D大鼠的肝脏,分散肝脏细胞并使之消化,再通过密度梯度离心,和细胞的贴壁时间的差异性,得到分离的肝星状细胞,并且量子点标记。将分离得到的大鼠的的原代HSC(静止表型),与HSC-T6细胞株(活化表型)依照一定的比值接种在提前用Mat...
