Experiments on transfusing young blood to slow aging have been going on for a long time, and despite the skepticism of some scientists and the potential danger, sometimes experiments give very encouraging results. Scientists from the University of Washington School of Medicine conducted a study in which elderly laboratory mice were transfused not with plasma, but with a certain protein of young individuals - in the end, they found that the recipients had improved vision and more energy.
The protein used is called eNAMPT, and it plays an important role in redox reactions inside cells. As a rule, in the organisms of young mice, this enzyme is found in excess, while its amount decreases with age - as a result, memory deteriorates in older organisms and problems with weight arise.
Scientists slow down aging of mice
By increasing the concentration of eNAMPT proteins in old mice, the researchers improved their insulin production, quick wits and visual acuity. They also calculated that mice without an excess of the enzyme live 16% longer than ordinary rodents.
At the moment, this effect has been found only in the case of laboratory mice, but Ambrosia Medical is already engaged in the transfusion of young blood into the elderly. The cost of transfusing a liter of rejuvenating blood costs $ 8,000, and two liters can cost $ 12,000.

Dangers of young blood transfusion
Some scientists, including New York University professor Mark Siegel, believe the company is simply cheating people. According to him, at the moment there is no scientific evidence of the anti-aging effect of young blood, and this procedure can even be dangerous.
Transfusion of young blood. Still from the series "Silicon Valley".
In particular, danger means the risk of oversaturation of the body with iron, transmission of infectious diseases, the occurrence of allergic reactions and weakening of immunity if the body does not accept donor blood. Nevertheless, Ambrosia Medical has quite a few clients - hundreds of people are on the waiting list for transfusions.
