But by identifying the specific cells involved, “we paved the way to early identification of people at risk of Alzheimer’s disease.” “This is exciting,” she said, “because all of this is happening before the clinical symptoms of dementia when we have much more hope of a cure.” Devastating disease Alzheimer’s disease affected Habib and her family personally, she said, as she watched her grandmother and other relatives suffer from memory loss and cognitive decline. ‫בעלון‬ ‫ בשעת הצורך הרשות נתונה לאמור מהדברים‬- .‫ לשמור‬/ ‫ להעתיק‬/ ‫ לחלק‬/ ‫להדפיס‬ ‫ אך הבא להדפיס יביא גאולה לעולם וידפיס בשם‬.‫שבעלון אף שלא בשם אומרם‬ .‫אומרו‬ In game-changer, Israeli researchers find Alzheimer’s markers 20 years before onset Hebrew University-led team maps 1.65 million brain cells from 437 aging brains; innovative algorithms predict brain cells’ trajectories, bringing ‘much more hope of a cure’ By DIANA BLETTER In a world first, researchers at the Hebrew University have discovered a distinct cellular pathway in the brain that indicates markers for future onset of Alzheimer’s disease, some 20 years before symptoms would be exhibited. Using a data set from the prefrontal cortex of 437 aging brains, the researchers mapped 1.65 million brain cells and showed that these cellular changes — that start at least 20 years before the first signs of dementia — determine the fate of the aging brain and the progression of Alzheimer’s Disease. Scientists either missed “relatively rare” molecules or “you wouldn’t know where the molecule comes from.” 4 But in the past few years, “with the help of an international collaboration,” she said, researchers built the data set to map 1.65 million brain cells. Hacking the brain Inside the brain are supportive glial cells, called microglia and astrocytes, that Habib and her research team believe start to change at the very early stage of Alzheimer’s, responding in a way that “really shapes the outcome.” Microglial cells monitor the brain for signs of damage or pathogens, such as bacteria and viruses, and act as the first line of defense against infections and disease. “Of course, for most individuals, there is a genetic risk for Alzheime
