Spinal Cord Oligodendrocytes is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Spinal cord oligodendrocytes are the myelin-forming cells of the central nervous system that ensheath axons with multilamellar myelin sheaths, enabling rapid saltatory conduction. They are essential for motor and sensory function and are affected in multiple sclerosis and ALS.
Oligodendrocytes are found throughout spinal cord white and gray matter. Each oligodendrocyte can myelinate multiple axons (up to 50) through formation of multiple myelin segments. In the ventral horn, they associate with motor neuron axons.
Produce compact myelin sheaths around axons.
Closely associated with neuronal cell bodies, thought to provide metabolic support.
Major structural protein of myelin sheath.
Surface protein specific to oligodendrocytes.
Transcription factor essential for oligodendrocyte lineage specification.
Proteoglycan expressed on oligodendrocyte progenitors.
