## Mechanistic Overview ACSL4 (acyl-CoA synthetase long-chain family member 4) catalyzes the esterification of arachidonic acid (AA, C20:4) and adrenic acid (AdA, C22:4) into membrane phospholipids, specifically phosphatidylethanolamines (PE-AA and PE-AdA) [PMID:27842070]. These PUFA-containing phospholipids serve as the primary substrates for iron-catalyzed lipid peroxidation—the biochemical hallmark of ferroptosis [PMID:27842070]. In disease-associated microglia (DAM), ACSL4 upregulation dram
