Area of Science:

  • Neuroscience
  • Genetics
  • Cell Biology

Background:

  • Human tauopathies, including Alzheimer's disease, are complex neurodegenerative disorders.
  • The fruit fly, Drosophila melanogaster, serves as a valuable model organism for studying these conditions due to its genetic tractability and conserved biological pathways.

Purpose of the Study:

  • To introduce Drosophila melanogaster as a model system for investigating human tauopathies.
  • To describe established protocols for analyzing human tau protein expression and its effects in flies.

Main Methods:

  • Utilizing light and scanning electron microscopy to visualize tau protein in the fly eye.
  • Employing confocal microscopy for detailed analysis of tau in primary neuronal cultures.
  • Preparing tissue homogenates for sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and Western blotting to detect and quantify tau protein.
