Ferroptosis is a form of regulated cell death that relies on the accumulation of intracellular iron and subsequent oxidative stress. Ferroptotic cell death is characterized by uncontrolled lipid peroxidation, which leads to plasma membrane damage and rupture. The loss of plasma membrane integrity results in the release of intracellular components, including damage-associated molecular patterns, and can propagate death between cells in a synchronized manner. Understanding the mechanisms of ferroptotic membrane damage is crucial to comprehending this form of cell death. This chapter provides a summary of techniques for detecting plasma membrane integrity in ferroptosis, including transmission electron microscopy analysis, flow cytometry analysis, and assessments of oxidoreductase-mediated membrane damage.
铁死亡是一种程序性细胞死亡形式,它依赖于细胞内铁的积累以及随后的氧化应激。铁死亡性细胞死亡的特征是不受控制的脂质过氧化,这会导致质膜损伤和破裂。质膜完整性的丧失会导致细胞内成分的释放,包括损伤相关分子模式,并能以同步方式在细胞间传播死亡信号。了解铁死亡性膜损伤的机制对于理解这种细胞死亡形式至关重要。本章总结了检测铁死亡中质膜完整性的技术,包括透射电子显微镜分析、流式细胞术分析以及对氧化还原酶介导的膜损伤的评估。
