Fig. 3From: Salidroside reduces tau hyperphosphorylation via up-regulating GSK-3β phosphorylation in a tau transgenic Drosophila model of Alzheimer’s diseaseEffect of salidroside on tau-induced neurotoxicity in vivo. Treatment of Sal and Donepezil rescued the neurodegeneration in TAU flies. Hematoxylin and eosin staining of a TAU fly brain (a). Hematoxylin and eosin staining of the brain of a TAU fly without any treatment (b), TAU fly treated with Sal (c), and TAU fly treated with Donepezil (d). Arrowheads indicate neurodegeneration.
