A shot of fresh teen blood in your veins can sometimes be a youth elixir. This is apparent from new American research, in which older mice became refreshed from an injection of young human blood.
Even though it looks a lot like a vampire film script, the results are promising.
American researchers have presented research results that show that young human blood can have a rejuvenating effect on an older body. Even if this older body is not from a human.
Mice run laps in the cage
The researchers took blood samples from a group of 18-year-old participants and injected the plasma into 12-month-old mice - similar to a 50-year-old human.
Over a three-week period, the mice received a shot of teenage blood twice a week. The mice started to run laps in their cages, and both their memory and learning capacity improved.
Proteins kill cells
According to neuroscientist Karoly Nikolich, founder of Alkahest, the biopharmaceutical company behind the research, the explanation lies in the protein composition of the blood.
Youthful blood contains various proteins that rejuvenate the tissue. However, as someone gets older, they disappear and make way for harmful molecules.
"As the plasma ages, the number of inflammatory proteins increases, which promote cell death," Karoly Nikolich explains.
Confirmation of previous research
The research was presented at an annual meeting of neuroscientists and has not yet been published.
However, it is not the first time that blood has been attributed a rejuvenating effect.
In 2014, a Harvard research group discovered that older mice benefited from injections of the blood of their younger counterparts, both physically and mentally.
