Possible Anti-Aging Brain Therapy Shows Promise in Mice – Scientific American


Clotho, one of the Three Fates of Greek mythology, carried the weighty responsibility of spinning the thread of human life. It seems fitting then that a protein linked to reducing and extending life spans should take its name from this mythic figure. Researchers discovered the klotho protein in 1997, when they found that diminished levels seemed to make the animals age faster. Conversely, mice genetically engineered to maintain elevated klotho levels live 30 percent longer than normal mice. Recent research hints that the protein itself could form the basis of anti-aging therapies.

Many studies have since established klotho as a longevity promoter, including in humans, with numerous protective effects on organs throughout the body. Its levels decline with age but some people with a version of the klotho gene known as KL-VS produce more of the protein and typically live longer. Now a…
