FASCINATING and this could have an ENORMOUS impact on aging and Alzheimer’s…

THE GUARDIAN: Villeda had conducted pilot studies with pairs of surgically conjoined mice that shared a blood supply for several weeks. Young mice received blood from older mice, and old mice received blood from younger ones. The statistics program took all the data and calculated the average number of newborn neurons in the brains of each group of mice. A moment later, bar charts popped up on the screen.

Villeda got three hours’ sleep that night. The next morning, he stood up at the lab meeting and revealed to his colleagues what young blood did to the ageing brain. “There was a palpable electricity in the room,” Wyss-Coray recalled. “I remember seeing the images for the first time and saying, ‘Wow.’” Old mice that received young blood experienced a burst of brain cell growth in the hippocampus. They had three to four times as many newborn neurons as their counterparts. But that was not all: old blood had the opposite effect on the brains of young mice, stalling the birth of new neurons and leaving them looking old before their time.
