This review examines how changes in tau protein, including its turnover, phosphorylation, and aggregation, contribute to neurodegenerative tauopathies like Alzheimer's disease.

Area of Science:

  • Neuroscience
  • Cell Biology
  • Biochemistry

Background:

  • Tau is a microtubule-associated protein crucial for neuronal function.
  • Altered tau metabolism is implicated in neurodegenerative diseases such as Alzheimer's disease.
  • Dysfunctional tau can lead to neuronal disorders known as tauopathies.

Purpose of the Study:

  • To review mechanisms of tau alteration in the onset of tau pathology.
  • To explore tau turnover, phosphorylation, and aggregation in relation to tauopathies.

Main Methods:

  • Literature review of tau protein metabolism and pathology.
  • Analysis of mechanisms driving tau alterations.

Main Results:

  • Alterations in tau amount, mutations, phosphorylation, and aggregation can cause tauopathies.

  • Changes in tau isoforms and expression levels are significant.

    • Conclusions:

    • Understanding tau alterations is key to deciphering tauopathy pathogenesis.
    • Targeting tau turnover, phosphorylation, and aggregation may offer therapeutic strategies.
