Briefing: Scientists found a protein that drives brain aging — and how to stop it

The FTL1 protein has been identified as a critical element influencing brain aging, with levels increasing in aging mice, according to a study published on April 5, 2026.

Elevated FTL1 levels have been shown to weaken synaptic connections between brain cells, which may contribute to observed memory decline in subjects.

These findings suggest potential pathways for intervention, highlighting the need for further research into the mechanisms by which FTL1 affects neural architecture and cognitive function.
