Glycogen synthase kinase-3 is associated with neuronal and glial hyperphosphorylated tau deposits in Alzheimer's disease, Pick's disease, progressive supranuclear palsy and corticobasal degeneration

Tau phosphorylation was examined in Alzheimer's disease (AD), Pick's disease (PiD), progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD) using phospho-specific tau antibodies recognizing the phosphorylated form of Ser202, Ser214 and Ser 396, and antibodies to non-phosphorylated glycogen synthase kinase-3α/β (GSK-3α/β), which regulates phosphorylation at these specific sites on tau and phosphorylated GSK-3βSer9 (GSK-3β-P);...
