Mechanistic description

OPCs show failure to differentiate due to elevated PDGFRA oscillation and hypomethylation of maturation genes. OPCs in AD brains show sustained PDGFRA expression, reduced MBP and PLP1, and epigenetic silencing of myelin genes, reflecting maturation arrest contributing to demyelination independent of primary oligodendrocyte loss.

Mechanism / pathway

  1. PDGFRA
  2. neurodegeneration

Evidence for (3)

Evidence against (2)

  • PDGFRA oscillation is normal OPC proliferation feature

    PMID:unavailable

  • OPCs in aged brain already maturation-arrested independent of neurodegeneration
