Abstract

Ferroptosis is an iron-dependent form of programmed cell death defined by the lethal accumulation of lipid peroxides. Accumulating evidence indicates that ferroptosis plays a critical role in a wide range of pathological processes, including tumor progression, ischemia-reperfusion injury, and neurodegenerative diseases. The key determinants of cellular susceptibility to ferroptosis are the homeostasis of iron and lipid metabolism, whose maintenance relies heavily on the precise regulation of inter-organelle communication networks. In this review, we focus on the spatial biology of ferroptosis regulation. From three core dimensions, iron homeostasis modulation, lipid metabolism remodeling, and redox balance maintenance, we systematically dissect the mechanisms by which signal crosstalk and functional coordination among multiple organelles (lysosomes, endoplasmic reticulum, mitochondria, plasma membrane, nucleus, lipid droplets, Golgi apparatus and peroxisome) govern ferroptosis initiation, signal amplification, and cellular defense responses. Comprehensive elucidation of this multi-organellar coordinated regulatory network will not only advance our fundamental understanding of ferroptosis execution but also provide a holistic perspective for the development of organelle-targeted therapeutic strategies against human diseases.
