Hypothesis

Can the IGF1R variant R407H prevent cognitive impairment and neuroinflammation in mice with Alzheimer's disease pathology?

Conclusion

Mice with the IGF1R variant showed better cognitive performance and reduced inflammation compared to wild type mice.

Supporting Evidence

  • Mice with the IGF1R variant performed better in spatial navigation tasks.
  • RNA sequencing showed significant downregulation of inflammatory cytokines.

Takeaway

Scientists studied mice to see if a special gene variant could help them think better and reduce brain inflammation related to Alzheimer's.

Methodology

C57BL/6 mice were injected with AAV9-PHP.eb and tested for cognition after 11 weeks.

Participant Demographics

14 female mice, aged 25 to 28 months.
