    Early NSC impairment in 3xTg-AD mice correlates with SVZ niche lipid accumulations • Similar lipid accumulations are found in the SVZ in postmortem human AD brains • Accumulating SVZ lipids are locally generated, oleic acid-enriched triglycerides • Inhibiting oleic acid signaling or synthesis rescues NSC defects in 3xTg-AD mice

    For the 1st time since the disease was described 109 years ago, researchers have discovered accumulations of fat droplets/ lipids in the brain of patients who died from the disease and h...
