应力颗粒剂(SGS)是含有受阻核糖核蛋白颗粒(的RNP),并且在对各种逆境的细胞应答重要的细胞质RNA的颗粒。超导重力仪的动态特性可以遵循的活细胞通过可视化的SG在应激后转染的原代细胞标记一个组件的国产化。

以下实验的总体目标是研究原代细胞中核糖核蛋白颗粒的动力学,尤其是应激颗粒的形成。这是通过首先从感兴趣的动物中培养小鼠、胚胎、成纤维细胞或海马神经元等细胞来实现的。作为第二步,转染应激颗粒的标记组分以允许其可视化。

接下来,对细胞进行应激诱导,并用延时共聚焦显微镜监测。获得的结果显示了 G 三个 BP one 的动力学,其中包含神话或镜像中的应激颗粒以及基于它们的直接可视化的海马神经元。这些方法可以帮助回答有关神经元等细胞中压力反应的关键问题。
