Oligodendrocytes are a type of glial cell, non-neuronal cells in the central nervous system.They arise during development from oligodendrocyte precursor cells (OPCs), [8] which can be identified by their expression of a number of antigens, including the ganglioside GD3, [9] [10] [11] the NG2 chondroitin sulfate proteoglycan, and the platelet-derived growth factor-alpha receptor subunit (PDGF ...
Neoplastic glial cells stained with an antibody against GFAP (brown), from a brain biopsy. While glial cells in the PNS frequently assist in regeneration of lost neural functioning, loss of neurons in the CNS does not result in a similar reaction from neuroglia. [18] In the CNS, regrowth will only happen if the trauma was mild, and not severe. [40]
“Identifying oligodendrocytes as significant contributors to beta-amyloid production should open up new avenues for therapeutic development that could target these glial cells alongside neurons ...
Oligodendrocyte progenitor cells (OPCs), also known as oligodendrocyte precursor cells, NG2-glia, O2A cells, or polydendrocytes, are a subtype of glia in the central nervous system named for their essential role as precursors to oligodendrocytes and myelin. [1] They are typically identified in the human by co-expression of PDGFRA and CSPG4.
The myelin sheath that surrounds and protects nerve cells is made by cells called oligodendrocytes. In a person with MS, these cells are lost, so damaged myelin sheaths cannot be repaired.
Gliosis is a nonspecific reactive change of glial cells in response to damage to the central nervous system (CNS). In most cases, gliosis involves the proliferation or hypertrophy of several different types of glial cells, including astrocytes, microglia, and oligodendrocytes.

Similarly derived, oligodendrocytes produce myelin, which insulates axons to facilitate electric signal transduction. Finally, microglial cells are derived from glial precursors and carry out macrophage-like properties to remove cellular and foreign debris within the central nervous system ref. Functions of glial-derived cell lineages are ...
