By helping the immune system remove dead cells, the body can regain some of its youth.
The best anti-aging would be our own body. According to new research by the Weizmann Institute of Science in Israel, helping the immune system remove dead cells would help the body remain young. Its results were published in Nature Communications magazine.
A study on rats
To obtain these results, the researchers used mice and concentrated on their senescent cells: dead or partially dead cells. These play a role in age-related diseases because they contribute to inflammation.
Scientists wanted to better understand the role of the immune system in aging: they gave the rats a drug that blocks the action of a protein, which allows the senescent cells to remain. The drug worked particularly well: the number of senescent cells in the body of rodents decreased. Blood tests were better, activity tests were better, and the tissues of these mice looked more like those of young mice than before. The mice also had fewer signs of inflammation, and the treatment also allowed the rodents to be more active and live longer.
Researchers must now continue to study these phenomena to understand how these mechanisms work in humans. Eventually, they will be able to test their hypotheses on humans, and perhaps one day they will make the long-awaited anti-aging elixir.
