Purpose of the Study:

  • Review current understanding of the amyloid hypothesis in AD.
  • Examine the role of soluble Abeta oligomers and intracellular Abeta.
  • Summarize novel transgenic mice models and their impact on AD pathogenesis research.

Main Methods:

  • Literature review of transgenic mice models for Alzheimer's disease.
  • Analysis of studies focusing on amyloid and Tau pathologies.
  • Synthesis of recent findings on novel mouse models.
