WebIn vitro, minocycline promoted OPC proliferation and increased the percentage of OPCs in S and G2/M phases. We provided direct evidence that early treatment is critical for minocycline to alleviate white matter and cognitive impairments after chronic cerebral hypoperfusion, which may be due to its robust effects on OPC proliferation and mature … WebOPC proliferation, OL differentiation, and maturation are the critical processes of OL myelination in the CNS. The extracellular signals, intracellular signaling pathways, and transcription factors regulating myelination are increasingly well-established, which shed light on human demyelinating diseases.
