## **Molecular Mechanism and Rationale** The senescence-associated myelin lipid remodeling hypothesis centers on the aberrant activation of phospholipase A2 (PLA2) enzymes, specifically PLA2G6 and PLA2G4A, within p21+ senescent oligodendrocytes. Under physiological conditions, myelin membranes maintain their structural integrity through a precise lipid composition rich in galactosylceramide, sulfatide, and phosphatidylcholine, which creates the optimal dielectric properties necessary for saltat...
