Iron associated lipid peroxidation in Alzheimers disease is increased in lipid rafts with decreased ferroptosis suppressors, tested by chelation in mice.

Iron-mediated cell death (ferroptosis) is a proposed mechanism of Alzheimers disease (AD) pathology. While iron is essential for basic biological functions, its reactivity generates oxidants which contribute to cell damage and death. To further resolve mechanisms of iron-mediated toxicity in AD, we analyzed postmortem human brain and ApoEFAD mice.
