摘要
Microtubule-associated protein tau undergoes several post-translational modifications and aggregates into paired helical filaments (PHFs) in Alzheimer's disease (AD) and other tauopathies. These modifications of tau include hyperphosphorylation, glycosylation, ubiquitination, glycation, polyamination, nitration, and proteolysis. Hyperphosphorylation and glycosylation are crucial to the molecular pathogenesis of neurofibrillary degeneration of AD. The others appear to represent failed mechanisms for neurons to remove damaged, misfolded, and aggregated proteins. This review summarizes the abnormal posttranslational modifications of tau and discusses the pathophysiological relevance of hyperphosphorylation and glycosylation of tau. Total tau and phosphorylated tau levels in cerebrospinal fluid as a diagnostic biomarkers are also reviewed. Analyses of the current advances in tau modifications suggest that intervention addressing these abnormalities may offer promising therapeutic opportunities to prevent and treat neurofibrillary degeneration of AD and other tauopathies.
