This hypothesis proposes that CYP2J2-derived DHA epoxides primarily function by promoting microglial M2 polarization rather than directly protecting synaptic membranes from Aβ-induced rigidification. Microglia are the primary phagocytic cells responsible for Aβ clearance, and their dysfunction contributes significantly to Alzheimer's disease pathogenesis. Evidence suggests that DHA epoxides, particularly 19,20-EpDPE, activate PPAR-γ signaling pathways that promote anti-inflammatory M2 microglial

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
