Ferroptosis becomes immunogenic: implications for anticancer treatments.

Ferroptosis is an iron-dependent form of non-apoptotic cell death that has recently been attributed with antitumor immune effects. Thus, early ferroptotic cells underwent immunogenic cell death that was accompanied by the emission of damage-associated molecular patterns (DAMPs) and triggered dendritic cell maturation in vitro. Furthermore, ferroptotic cells were able to vaccinate against a rechallenge with fibrosarcoma in preclinical models.
