Macroautophagy (hereafter referred to as autophagy) is an evolutionarily conserved cellular process capable of degrading various biological molecules (e.g., protein, glycogen, lipids, DNA, and RNA) and organelles (e.g., mitochondria, endoplasmic reticulum [ER] ribosomes, lysosomes, and micronuclei) via the lysosomal pathway. Ferroptosis is a type of oxidative stress-dependent regulated cell death associated with iron accumulation and lipid peroxidation. The recently discovered role of autophagy, especially selective types of autophagy (e.g., ferritinophagy, lipophagy, clockophagy, and chaperone-mediated autophagy), in driving cells toward ferroptotic death motivated us to explore the functional interactions between metabolism, immunity, and cell death. Here, we describe types of selective autophagy and discuss the regulatory mechanisms and signaling pathways of autophagy-dependent ferroptosis. We also summarize chemical modulators that are currently available for triggering or blocking autophagy-dependent ferroptosis and that may be developed for therapeutic interventions in human diseases.
自噬(以下简称自噬)是一种进化上保守的细胞过程,能够通过溶酶体途径降解各种生物分子(如蛋白质、糖原、脂质、DNA 和 RNA)和细胞器(如线粒体、内质网[ER]核糖体、溶酶体和微核)。铁死亡是一种与铁积累和脂质过氧化相关的氧化应激依赖性调节细胞死亡。最近发现的自噬作用,特别是选择性自噬(如铁蛋白自噬、脂自噬、生物钟自噬和伴侣介导的自噬)在驱动细胞走向铁死亡的作用,促使我们探索代谢、免疫和细胞死亡之间的功能相互作用。在这里,我们描述了选择性自噬的类型,并讨论了自噬依赖性铁死亡的调节机制和信号通路。我们还总结了目前可用于触发或阻断自噬依赖性铁死亡的化学调节剂,这些调节剂可能会被开发用于人类疾病的治疗干预。
