Image-Based Analysis of Intracellular Tau Aggregation by Using Tau-BiFC Cell Model

Area of Science:

• Neuroscience
• Cell Biology
• Drug Discovery

Background:

• Abnormal tau protein aggregation is a central pathological feature of tauopathies, a class of neurodegenerative diseases.
• Targeting tau aggregation is a crucial therapeutic strategy for neurodegenerative disorders.

Purpose of the Study:

• To introduce a novel cell-based model for investigating intracellular tau aggregation.
• To establish a high-throughput screening method for quantifying tau aggregation.

Main Methods:

• Utilized a recently developed tau aggregation cell-based model, termed tau-BiFC.
• Developed a high-throughput and high-content screening approach to quantify intracellular tau aggregation.

Main Results:

• The tau-BiFC model effectively allows for the investigation of intracellular tau aggregation.
• The developed screening method enables efficient quantification of tau aggregation within cells.

Conclusions:

• The tau-BiFC model and associated screening method can accelerate the discovery of novel therapeutic agents.
• This approach holds promise for developing treatments for tau-mediated neurodegeneration.
