Vampires: The Science of Young Blood
There is a scientific concept of rejuvenation through young blood called the young blood treatment. In this treatment, individuals receive infusions of young blood plasma to rejuvenate their brain and organs, potentially leading to a longer and better life. Studies on mice have shown that sharing blood supply between young and older mice can rejuvenate the older mouse's brain. Moreover, injecting young mouse plasma into older mice also rejuvenated their brain and other organs. While the exact mechanism is not yet understood, proteins like GDF 11, osteopontin, and TIMP2 have all shown potential in improving cognitive performance and extending lifespan. Although the young blood trial has been suspended, research into the benefits of young blood and its potential applications continues.
