This is the first part of a diaeventontological framing of lipid peroxidative mechanisms for CNS neurodegeneration. Dr Guerra describes recent published research (JLR 2018 .59:312pp.) and develops some of the key elements of the ferroptosis programmed cell death mechanism leading to oligodendrocyte and neuronal degeneration that will participate in a grander understanding of injury-induced and idiotypic age-associated disease in the CNS. 25 March 2019.
