Young Human Blood Makes Old Mice Smarter

April 19, 2017

(Nature) – A protein found in young human blood plasma can improve brain function in old mice. The finding, published on 19 April in Nature, is the first time a human protein has been shown to have this effect. It’s also the latest evidence that infusions of ‘young blood’ can reverse symptoms of ageing, including memory loss, decrease in muscle function and metabolism, and loss of bone structure. For decades, researchers have studied the effects of young blood on ageing in mice through a technique called parabiosis, in which an old mouse is sewn together with a younger one so that they share a circulatory system.
