**Molecular Mechanism and Rationale**
The neurexin-neuroligin trans-synaptic adhesion system represents a critical molecular bridge that maintains synaptic integrity while potentially facilitating pathological tau propagation in neurodegenerative diseases. Neuroligin-1 (NLGN1), the primary target of this therapeutic approach, is a postsynaptic cell adhesion molecule that forms heterotypic interactions with presynaptic neurexins (NRXN1, NRXN2, NRXN3). This interaction occurs through the extracel
## 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
