WebIntroduction. Ferroptosis is a newly identified type of iron-dependent programmed cell death that was first reported by Dixon et al in 2012. 1 As a new type of programmed cell death, ferroptosis is different from apoptosis, autophagy, necrosis, pyrolysis and other forms of cell death in terms of morphology and biochemistry.
