Apoptosis in oligodendrocytes is associated with axonal degeneration in P301L tau mice.

Abstract excerpt

Transgenic mice overexpressing human tau with the P301L mutation develop neurofibrillary tangles, extensive gliosis, adult-onset motor abnormalities, and neuronal loss in affected brain regions. We investigated the mechanism of neuronal cell death in this model of tauopathy. There was no evidence of neuronal apoptosis at any age; however, a population of oligodendorocytes was immunopositive for TUNEL and...
