Suprachiasmatic Nucleus Circadian Neurons In Neurodegeneration is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
NG2 cells, also known as NG2 glia or oligodendrocyte precursor cells (OPCs), are a distinct population of glial cells in the central nervous system. They express the NG2 proteoglycan (also known as CSPG4) and platelet-derived growth factor receptor alpha (PDGFRα).
NG2 cells, also known as polydendrocytes or NG2-positive glial progenitor cells, are a distinct population of glial cells in the central nervous system that serve as progenitors for oligodendrocytes. These cells express the NG2 proteoglycan (also known as CSPG4) and are characterized by their unique morphology with multiple branched processes. NG2 cells receive synaptic input from neurons, suggesting they play roles in neuronal-glial communication. In demyelinating diseases and after injury, NG2 cells can proliferate and differentiate into remyelinating oligodendrocytes, making them important therapeutic targets for regenerative medicine.
NG2 cells are distributed throughout gray and white matter of the brain and spinal cord. They represent approximately 5-10% of all glial cells in the adult CNS.
NG2 cells arise from neural progenitor cells during embryonic development. They proliferate and migrate throughout the CNS before differentiating into oligodendrocytes.
NG2 cells are critical in MS:
NG2 cells show alterations in AD:
