Protein from the blood of young mice prolonged the life of elderly rodents

Researchers have proposed a hypothesis explaining how transfusions of young blood can help reverse

the effects of aging. Their work concerned the search for components of a compound called nicotinamide-adenine dinucleotide (NAD) - in the past few years, it has been the subject of numerous studies on anti-aging.

Scientists have previously found that NAD is of great importance for healthy energy metabolism, and its levels are systematically reduced in all tissues of the body with age.

In their work, biologists transplanted to elderly mice a protein called eNAMPT, which circulates in the bloodstream and plays a fundamental role in the biosynthesis of NAD.

We found a whole new way to healthyaging. We took the eNAMPT from the blood of young mice and transplanted it to older mice. As a result, elderly mice showed a marked improvement in their health. In particular, they began to move more and sleep better. This is a great result.

Earlier, an international team of scientists was able to prove that aging doubles the risks of chronic diseases every eight years of life. Also, scientists were able to discover the genes associated with this process.
