New Alzheimer's treatment shows promise in mice
Scientists have found a new way to tackle Alzheimer's in mice—using tiny nanoparticles to repair the brain's protective barrier.
Led by teams in Spain and China, this approach focuses on fixing blood vessels instead of just targeting brain cells, hinting at a fresh direction for future treatments.
Nanoparticles helped clear amyloid-B, improving memory
Researchers gave mice special nanoparticles that helped clear out amyloid-b, the toxic protein linked to Alzheimer's.
In just an hour, these levels dropped by up to 60%, and the mice showed better memory for several months—no damage or toxicity was observed in animals, and they tolerated the therapy well.
Targeting blood vessels could be a game-changer
By repairing the blood-brain barrier, this method improved how the brain removes waste and controls inflammation.
While it's early days and more research is needed before trying this in people, targeting blood vessels with bioactive nanoparticles could be a big step forward in Alzheimer's research.
