Mechanistic description
Oligodendrocyte Precursor Cell Activation to Restore Structural Connectome Integrity
Mechanism / pathway
- Oligodendrocyte Precursor Cell
- connectomics
Evidence for (5)
Myelin breakdown is an early, underrecognized feature of AD pathophysiology
Hub regions connected by long-range white matter tracts that are particularly vulnerable
Clemastine promotes OPC differentiation and remyelination in cuprizone and EAE models
Siponimod (Mayzent) FDA-approved for secondary progressive MS
Network-level changes include reduced white matter integrity measurable by diffusion MRI
Evidence against (5)
Myelin changes in AD may be secondary to axonal degeneration - primary vs secondary unresolved
White matter hyperintensities correlate with vascular pathology, not primary OPC dysfunction
Clemastine not advanced to AD clinical trials - off-target antihistamine effects
Siponimod failed in secondary progressive MS - S1P modulation insufficient for established myelin pathology
Aged human OPCs have substantially reduced differentiation capacity vs young animals
