Blood from young mice improved learning and memory in older mice, and increased connections between their brain cells
Saul Villeda of Stanford University, who led the work, found that blood from young mice reversed some of the effects of ageing in the older mice, improving learning and memory to a level comparable with much younger animals. He said that the technique could one day help people stave off the worst effects of ageing, including conditions such as Alzheimer’s.
“Do I think that giving young blood could have an effect on a human? I’m thinking more and more that it might,” said Villeda. “I did not, for sure, three years ago.”
When he put the animals into a water maze, a test where they have to remember the location of a hidden platform, he found that the older mice did almost as well as mice of 4-6 months old. Untreated older mice would make many errors and swim down blind alleys in their attempts to find the hidden platform, whereas the mice that had received plasma from young mice located the platform first time, in most cases.
