Comparing 2 hypotheses side-by-side
**Molecular Mechanism and Rationale** The molecular foundation of this therapeutic approach centers on restoring the biosynthetic capacity for lipoxin A4 (LXA4), a specialized pro-resolving mediator (SPM), specifically within reactive astrocytes through targeted ALOX15 gene delivery. ALOX15 (15-lipoxygenase) serves as the rate-limiting enzyme in the biosynthetic pathway that converts arachidonic acid to 15-HETE, which is subsequently converted to LXA4 through a transcellular mechanism involving
## Molecular Mechanism and Rationale ALOX15 (15-lipoxygenase) catalyzes the stereospecific oxygenation of polyunsaturated fatty acids (PUFAs) esterified to phosphatidylethanolamine (PE) at the sn-2 position, generating 15-hydroperoxyeicosatetraenoic acid-PE (15-HpETE-PE) and other lipid hydroperoxides that serve as initiating signals for ferroptosis. In oligodendrocytes, which maintain exceptionally high PUFA-PE content due to myelin membrane biosynthetic requirements, ALOX15 activity is amplif
