In 2012, while investigating the mechanism of Erastin-induced cell death, Dixon and colleagues formally coined the term ferroptosis to describe this iron-dependent, lipid peroxidation-mediated form of regulated cell death ( Compared with other forms of cell death, such as autophagy, apoptosis, and pyroptosis, ferroptosis exhibits distinct morphological, biochemical, and immunological characteristics (Xia et al., 2025)
In the decades since, researchers have repeatedly returned to it as an open question in neurochemistry, with one influential review aptly describing it as a "still unresolved riddle" (Kovalzon et al., 2006)
