Boosting this protein helps brain cells clear Alzheimer's plaques: Study

Technology Nov 30, 2025

Researchers just found that raising levels of a protein called Sox9 in the brain's support cells helps clear out the sticky plaques tied to Alzheimer's.
In mouse studies, boosting Sox9 meant fewer plaques and better memory—even after symptoms had already started.

Why does this matter?

When scientists lowered Sox9, memory got worse and plaques piled up, showing how important this protein is for brain health.
This opens up a new path for Alzheimer's treatment—focusing on helping the brain clean itself up, not just targeting neurons or blocking plaque formation.
It's early days, but it could mean new hope for fighting memory loss down the line.
