Oligodendrocyte

CNS myelin-forming glia; one cell myelinates 15–40 axon segments, boosting conduction from ~0.5 to ≥70 m/s via saltatory conduction. OPCs (NG2+PDGFRα+) persist as adult progenitors. MCT1-derived lactate provides metabolic support to axons independent of insulation.

Also known as: OL, myelinating glia, CNS myelin-forming cell, OPC, oligodendrocyte precursor cell
