Tau and tauopathies

Tau and tauopathies


Tau proteins are abundant in neurons and function to stabilise microtubules. Microtubules provide both a scaffold for the cell and a means of transporting substances around the cell. They are mainly found in the axon of a neuron and are absent in the dendrites. The tau protein is coded for by a gene on chromosome 17.

Hyperphosphorylation of tau leads to tau clumping together (these clumps are referred to as neurofibrillary tangles) and cells then disintegrate.

Major tauopathies include:-

  • Alzheimer's
  • Pick's (frontotemporal dementia)
  • Progressive supranuclear palsy
  • Cortiocobasal degeneration
