Transgenic zebrafish lines for Alzheimer’s disease models

This technology is a set of transgenic zebrafish lines expressing hallmark proteins of Alzheimer’s disease with similar pathology to human brains for use as a tool in early drug development.

Unmet Need: Accurate in vivo model for Alzheimer’s disease that mimics human pathologies

Alzheimer’s disease is a neurodegenerative disorder affecting millions of people globally, but treatments for this debilitating disease remain inadequate. Accurate animal models are essential for understanding disease mechanisms and early drug development, but existing in vivo models do not sufficiently recapitulate human pathologies. A more accurate animal system that mimics human Alzheimer’s disease conditions would advance understanding of this disorder and promote more efficient drug screening toward better therapies.

The Technology: Genetically modified zebrafish lines expressing amyloid beta 42 and Tau to model basic biochemical alterations in human brains with Alzheimer’s disease

This technology introduces zebrafish lines including multiple variations of genetic modifications expressing amyloid beta 42 and Tau, two hallmark proteins of Alzheimer’s disease, in relevant cell types. These animal models display basic biochemical alterations similar to those in human Alzheimer’s disease patients, thus presenting a tool for Alzheimer’s disease research with more accurate pathologies.

These zebrafish lines have been validated in vivo and compared to human Alzheimer’s disease cohort datasets.

Applications:

  • Drug screening for Alzheimer’s disease therapeutics
  • Research tool for Alzheimer’s disease biomarker identification
  • Research tool for functional genomics

Advantages:

  • Model with similar pathology to human brains for disease analysis and drug screening
  • Expresses important hallmark proteins of Alzheimer’s disease, amyloid beta 42 and Tau
  • Enables in vivo pre-clinical drug screening in a safe and cost-effective manner compared to other animal models
