How one protein spreads Alzheimer's Tau in mouse brains
New research in mice indicates that a protein named Arc facilitates the transmission of toxic Tau proteins between brain cells, exacerbating Alzheimer's. Arc normally carries information in tiny bubbles between neurons, but toxic Tau hitches a ride in these bubbles from sick cells to healthy ones. Scientists hope therapies could target this spread, potentially stopping the disease from progressing in humans.
