Myelination by oligodendrocytes

WebAlpha-synuclein (aSyn) aggregation within mature oligodendrocytes is the characteristic neuropathological feature of multiple system atrophy (MSA). In fact, dysfunction of oligodendrocytes is considered as a primary event in MSA pathogenesis leading to myelin loss and, ultimately, reduced axonal integrity and neuronal cell loss. WebDescription.
