Autophagic cell death can be conveniently studied in Dictyostelium discoideum, an exceptionally favorable model not only because of its well-known genetic and experimental advantages but also because in Dictyostelium there is no apoptosis machinery that could interfere with nonapoptotic cell death. Moreover, autophagic cell death in Dictyostelium can be dissociated into a starvation-induced sensitization stage, during which autophagy is induced, and a death induction stage. We show here how to demonstrate, assess and analyze this autophagic cell death. This can be studied in vivo during the development of Dictyostelium, and in vitro, using modifications of the monolayer technique of Rob Kay et al. Methods to follow this autophagic cell death qualitatively and quantitatively are reported.
自噬性细胞死亡可以在盘基网柄菌中方便地进行研究,盘基网柄菌是一个非常理想的模型,不仅因为其众所周知的遗传和实验优势,还因为在盘基网柄菌中不存在可能干扰非凋亡性细胞死亡的凋亡机制。此外,盘基网柄菌中的自噬性细胞死亡可分为饥饿诱导的致敏阶段(在此阶段诱导自噬)和死亡诱导阶段。我们在此展示如何证明、评估和分析这种自噬性细胞死亡。这可以在盘基网柄菌发育过程中进行体内研究,也可以在体外使用罗布·凯等人的单层技术的改良方法进行研究。本文报道了定性和定量追踪这种自噬性细胞死亡的方法。
