It may finally be known why the blood of young people can rejuvenate old brains
Scientists are rejuvenating mice by infusing them with blood not only from younger mice but also from teenagers. We now have the first clues as to why this technique works.
Researchers have found an enzyme that can help ageing brains avoid cognitive decline. It’s been tested on mice so far, but if it can be replicated in humans, a whole new class of antiaging therapies could emerge.
Researchers led by Saul Villeda, a neurobiologist at the University of California in San Francisco, found that infusing older mice with blood from young mice improved their learning and memory by strengthening the connections in the hippocampus.
