Myelinating oligodendrocytes are the mature, myelin-producing cells of the central nervous system (CNS). Each oligodendrocyte can myelinate up to 60 axonal segments, forming the essential electrical insulation that enables rapid saltatory conduction of action potentials[@baumann2001][@nave2014].

Myelinating oligodendrocytes are the mature, myelin-producing cells of the central nervous system (CNS). Each oligodendrocyte can myelinate up to 60 axonal segments, forming the essential electrical insulation that enables rapid saltatory conduction of action potentials[@baumann2001][@nave2014].
Myelinating Oligodendrocytes are a specialized cell type classified within the Glia > Oligodendrocyte > Myelinating pathway. These cells are primarily found in White Matter, gray matter, and subcortical regions, characterized by expression of marker genes including MBP, PLP1, MOG, CNP, and MAG. They are selectively vulnerable or involved in multiple sclerosis, Alzheimer's disease, Parkinson's disease, ALS, and Huntington's disease["@simons2015"].

Myelinating oligodendrocytes possess distinct morphological features:
The myelin sheath is composed of lipids and proteins:
| Component | Percentage | Function |
|-----------|-------------|----------|
| Lipids | 70-85% | Insulation, membrane structure |
| Proteins | 15-30% | Myelin stability, adhesion |
| MBP | 30% of protein | Myelin compaction |
| PLP1 | 50% of protein | Myelin integrity |
| MOG | 0.1% of protein | Surface recognition |
Myelinating oligodendrocytes enable rapid nerve impulse transmission:
Oligodendrocytes provide metabolic support to axons:
Myelination provides structural and functional protection:
In MS, myelin loss is the hallmark pathological feature:
Alzheimer's disease involves white matter abnormalities:
Parkinson's disease shows:
Amyotrophic lateral sclerosis features:
