Brain protein may reverse age-related memory loss

Reducing FTL1 protein reversed memory loss in older mice, study finds.

Why it matters

  • FTL1 protein linked to memory loss.
  • Reversing FTL1 restored memory in mice.
  • New target for cognitive decline treatments.

By the numbers

  • High FTL1 in older mice' hippocampus.
  • Reduced FTL1 improved memory and synapses.
  • FTL1 also slowed metabolism in hippocampal cells.

The big picture

  • FTL1 could reverse cognitive decline.
  • Brain aging may be more reversible than thought.
  • Potential for Alzheimer's treatments.

What they're saying

  • Villeda: "True reversal of impairments."

Caveats

  • Mouse study; human effects unknown.
  • More research needed.

What’s next

  • Develop FTL1-targeted therapies.
  • Future human trials possible.
