oligodendrocyte

(ol?i-go-den'tro-sit) [? + ? + kytos, cell]
A glial cell found most commonly in axon tracts; it myelinates axons in the central nervous system just as Schwann cells myelinate axons in the peripheral nervous system. Oligodendrocytes are neuroectodermal cells that originate from different precursors in the neural tube than astrocytes; later, stem cells in the subependymal layer can continue to generate new oligodendrocytes. Mature oligodendrocytes wrap neighboring axons in myelin, and some oligodendrocytes can simultaneously wrap many axons. However, not all oligodendrocytes myelinate axons.

The cells that need iron during this critical period of development are called oligodendrocytes, which produce myelin and wrap it around axons.
In the CNS, neuroinflammation is the typical consequence of the interchange among different cell types, particularly neurons, astrocytes, oligodendrocytes and microglia, of a variety of cues as neurotransmitters, cytokines, chemokines, toxic metabolites that condition the final protein/mRNA pro files of cells, their activation states and functional outcomes [2, 3].
