Can treat Alzheimer's with ... human blood

Until now, it was rare for the scientific community to admit myths like vampires. But a recent study in mice has shown that there may be a "young source" in the blood of healthy young people.

Scientists have recently discovered an interesting fact: The transfusion of young mice to adult mice will reverse the aging process. So researchers are coming up with the next hypothesis: Transfusion of young people's blood to people with Alzheimer's disease.

The first human test of the effectiveness of this method will be conducted in October at Stanford School of Medicine. Mild to moderate Alzheimer's patients will receive plasma from volunteers under 30 years old. Although this experiment sounds like a vampire movie scenario, it is still easily allowed by officials - according to research leader Tony Wyss-Coray. Anyway, human-to-human blood transfusions have become very normal for centuries - just as there are no adequate studies of blood health effects.

If this blood transfusion works in people like a mouse, then the brain function of the patients participating in the experiment will improve immediately - but perhaps only temporarily. In mice, transfusion of young offspring also makes their muscles heal faster and reverse the aging process of internal organs. The opposite also occurs when young children are transfused with adult blood.

"So blood can also contain" fresh springs "," Wyss-Coray said, "and it is in each of us . " Stream "that only loses its power when people follow. five months".

While plasma transmissions have become popular today, it will be more convenient if one can determine what the young person's blood can cure. Scientists have an idea: a protein called " growth differentiation factor " (GDF11) will decrease with age. Mice when injected with GDF11 will have a brain that contains more new blood vessels and stem cells, miraculous signs that brain function is recovering.

And now let's wait and see whether young people's blood works the same way in humans. This may be the best or worst thing that ever happened to mankind - depending on your point of view.
