Scientists may have overlooked a hidden Alzheimer's culprit for decades
Key Takeaways
  • Researchers report that the peptide P3 can form protein aggregates faster than amyloid beta in laboratory experiments.
  • P3 was previously assumed harmless but is now shown to potentially damage brain cells in vitro.
  • The study reframes P3 as a candidate pathological species that may merit therapeutic and diagnostic attention.
