摘要

Tau is a neuronal microtubule-associated phosphoprotein that is highly phosphorylated by glycogen synthase kinase 3 (GSK3). Tau phosphorylation by GSK3 regulates tau binding to microtubules, tau degradation and tau aggregation. Tau phosphorylation is important in Alzheimer disease pathology and in other tauopathies. In Alzheimer disease, it has been proposed that the peptide beta amyloid promotes GSK3 activation, resulting in tau phosphorylation. In this work, we review the links between beta amyloid peptide, tau protein and GSK3 that occur in familial Alzheimer disease. We also discuss the possible links between GSK3 and sporadic Alzheimer disease. Finally, we include a brief review of the pathology of animal models overexpressing GSK3.
