The vampire molecule: scientists discover why young blood helps reverse aging

Scientists have identified a ‘master regulator’ in young blood that can mostly reverse aging in the brain.

The vampire molecule: scientists discover why young blood helps reverse aging

Young blood has rejuvenating, anti-aging properties that scientists are trying to tap into. A new study published in the journal Cell Reports now brings us one step closer to determining what it is in the young blood that age-reversing properties.

A few years ago, scientists discovered that when they gave young blood to old mice, something pretty astounding happens in their brains. The older mice get more stem cells, produce more neurons, the connections between their neurons become stronger, and their spatial memory improves. The effects of aging in the brain are, in large part, reversed.

Dr. Saul Villeda, an assistant professor of anatomy at the University of California San Francisco, is the senior author on the new study. His lab made the initial discovery that older mice’s brains start behaving like younger ones, when old and young mice are surgically attached together. It’s a process called parabiosis. Not only that, but the younger mice’s brains appear older too.   Read More…
