Scientists just found about 150 hidden DNA “switches” in brain support cells (astrocytes) that control genes linked to Alzheimer’s. Most of our DNA doesn’t make proteins, but these switches can turn genes on or off—sometimes from far away! Using CRISPRi, researchers silenced these switches to see which genes changed, helping pinpoint where Alzheimer’s risk really comes from. It’s a game-changer for understanding how the brain’s wiring goes haywire in disease! #Health #BodyHealth #Alzheimers
