**Molecular Mechanism and Rationale** The valosin-containing protein (VCP), also known as p97, represents a critical hexameric AAA+ ATPase that orchestrates multiple cellular quality control pathways, including autophagy, endoplasmic reticulum-associated degradation (ERAD), and proteasomal degradation. In the context of tauopathies, VCP functions as a key regulatory hub for tau aggregate clearance through its essential role in autophagosome maturation and lysosomal fusion. The molecular mechani

## 1. Molecular Mechanism and Rationale 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). These polyunsaturated fatty acid (PUFA)-containing phospholipids serve as the primary substrates for iron-catalyzed lipid peroxidation—the biochemical hallmark of ferroptosis. In disease-associated microglia (DAM), ACSL4 upre
