Nanoparticle Therapy Reverses Alzheimer’s Progression in Mice

Alzheimer’s disease remains irreversible largely because the adult brain cannot replace lost neurons; Wang et al. present a Nano-ERASER-based Trim-Away system that enables adult neuroregeneration in Alzheimer’s brain. Image credit: Wang et al., doi: 10.1016/j.celbio.2026.100575.

Researchers have developed a nanoparticle-based treatment that appears to improve performance on standard memory and learning tests as well as reduce brain inflammation and levels of amyloid-beta in mice with Alzheimer’s disease by converting star-shaped brain cells called astrocytes into functioning neurons.
