WHAT’S BEING CLAIMED:
- Transfusion of blood from young mice to old mice has shown that some youthful properties can also be transferred.
- New research has narrowed down the focus to not just young blood, but a specific protein called eNAMPT.
- Research suggests that levels of eNAMPT in the blood heavily dictates the length of lifespan and healthy aging.
Maybe the key to youth isn’t water from a fountain, but blood. Young blood to be exact.
The idea that transfusions of young blood can reverse aging effects has been around for a while. Now, a new study published in the journal Cell Metabolism has found that when a certain protein from the blood of young mice can do just that when transfused to older mice.
Anti-aging research done over recent years has set their focus on the nicotinamide adenine dinucleotide (NAD) compound. It’s been found that the compound is key to healthy energy metabolism. However, as we age, the levels of NAD decline.
Shin-ichiro Imai, the senior author of the new study, says that both their research as well as others suggest how NAD “governs how long we live and how healthy we remain as we age.” Thus, many have poured their efforts into finding ways to maintain the levels of the compound in the body as we people get older.
The new research from Washington University School of Medicine in St. Louis has identified a specific protein, eNAMPT, found in the bloodstream which is fundamental when it comes to the biosynthesis of NAD. Imai says taking this protein in particular and transfusing it may be the key to healthy aging.
They tried this with mice, and the older subjects showed youthful characteristics like “increased physical activity and better sleep”, better eye function, cognitive performance, and the extension of the animals’ lifespan by around 16%.
Still, results of this research have only shown verified results in animal studies. It’s still unsure whether the transfusion of eNAMPT in humans will have the same effects and benefits.
