What specific molecular mechanisms link APOE4 to cholesterol dysregulation in oligodendrocytes?

PARTIALLY ADDRESSED

The abstract identifies APOE4's primary effect on oligodendrocyte cholesterol metabolism but doesn't explain the mechanistic pathway. Understanding this mechanism is critical for developing targeted therapeutics that address the root cause rather than downstream effects. Gap type: unexplained_observation Source paper: APOE4 impairs myelination via cholesterol dysregulation in oligodendrocytes (2022, Nature, PMID:34788101)
