Area of Science:

  • Neuroscience
  • Cell Biology
  • Biochemistry

Background:

  • Phosphorylated tau filamentous inclusions are a hallmark of Alzheimer's disease (AD).
  • Tau accumulation correlates with cognitive decline in AD and related tauopathies.
  • Targeting early tau aggregation is a potential therapeutic strategy for neurodegenerative diseases.

Purpose of the Study:

  • To establish cellular models for studying tau aggregation.
  • To facilitate cost-effective screening of compounds that inhibit tau filament assembly.
  • To investigate the early stages of pathological tau formation.

Main Methods:

  • Generation of conditional transfectants from human neuroglioma (H4) and neuronal (BE(2)-M17D) cells.
  • Inducible expression systems to control transgenic wild-type or mutant tau expression.
