Hypothesis

Does fisetin provide similar or better senolytic effects compared to dasatinib plus quercetin in tau transgenic mice?

Conclusion

Both senolytic treatments were equally protective against neurodegeneration, but dasatinib plus quercetin had a greater effect on tau neuropathology.

Supporting Evidence

  • Both senolytic treatments reduced brain pathology in tau transgenic mice.
  • D+Q showed a greater effect on tau neuropathology compared to vehicle treatment.
  • Treatment-specific effects were observed with genotype interactions.

Takeaway

Researchers tested two treatments to help mice with brain problems caused by tau protein. Both treatments worked well, but one was better at fixing brain damage.

Methodology

Fourteen-month-old male and female wild type and tau transgenic mice were treated with either dasatinib plus quercetin, fisetin, or a vehicle for 12 weeks, with various physical and behavioral outcomes measured.

Participant Demographics

Fourteen-month-old male and female wild type and tau transgenic mice.
