We studied underlying pathomechanisms in tauopathies using pR5 mice that express the P301L tau mutation found in familial forms of frontotemporal dementia. In a longitudinal study we investigated the functional status of glycogen synthase kinase-3 and correlated it with the appearance of distinct tau phospho-epitopes. Neurons displaying increases in(More)
Histopathological studies on the brains of tauopathy cases including cases with Alzheimer's disease (AD) demonstrate that neurons with hyperphosphorylated protein tau display granulovacuolar degeneration (GVD), as evidenced by vacuolar lesions harboring a central granule, together with markers of the activated unfolded protein response (UPR).
