Neuroscientists have discovered immune cells that can slow down the aging of the body

Alon Monsonego, a professor at the Shragi Segal Department of Microbiology, Immunology and Genetics at the Faculty of Medical Sciences at Ben-Gurion University, discovered a unique subset of T-helper lymphocytes, the number of which increases with age and may play a key role in slowing aging. This was reported on November 16 by Science Daily magazine.

According to Monsonego, these cells reflect a person's biological age and may not match their chronological age. The significance of the discovery was reinforced by Japanese work on centenarians over 100 years old — they had the same type of T-cells present in increased numbers. The professor suggested that these cells help maintain an immune response appropriate to a person's age.

As the body ages, cells lose their ability to recover normally, and senescent cells begin to accumulate, causing inflammation and tissue damage. Scientists have discovered that some of the age-related T-helper cells have "killing" properties capable of destroying such senescent cells and limiting their harm.

Experiments on mice have shown that reducing the number of these T cells accelerates aging and shortens the lifespan of animals. Since the level of these cells changes with age, the researchers suggest tracking the immune profile of people starting at the age of 30, which will allow them to assess their biological age and correct aging-related processes in time.

"They say that to reverse aging and rejuvenate, you need to reboot the immune system, as in people in their 20s, but our research shows that this may not be the case. People don't need a super-powerful immune system, they need one that works properly and fits their life stage. Thus, one of the "axioms" about how to slow down aging may be incorrect," Monsonego emphasized.

Scientists believe that the discovery will help develop new diagnostic methods and potential therapies aimed at healthy longevity and correcting impaired aging.
