The hypothesis proposes that ω-3 docosahexaenoic acid (DHA) is metabolized by CYP2J2 to generate protective epoxides that shield synaptic membranes from amyloid-beta (Aβ)-induced rigidification. Evidence from planar lipid bilayer experiments demonstrates that CYP2J2-derived epoxides mitigate Aβ-induced membrane rigidity (pmid:31243156). Aβ oligomers are known to increase membrane cholesterol content by approximately 40% and expand raft domain size in cortical neurons (pmid:24503041). Supporting
LXRβ-selective agonism represents a targeted strategy to simultaneously enhance APOE lipidation and reduce microglial cholesterol accumulation, addressing two interrelated pathogenic mechanisms in APOE4-associated neurodegeneration. The approach exploits the predominant CNS expression of LXRβ (NR1H2) to achieve therapeutic effects while potentially avoiding the hepatic lipogenic effects mediated by LXRα. Supporting this rationale, LXRβ-deficient mice develop age-dependent neurodegeneration with
