Israeli scientists have figured out how to slow down aging
Israeli scientists have figured out how to slow down the aging process, according to the local edition of Blood .
Initially, the specialists of the Technion Israel Institute of Technology wanted to understand why the most severe course of coronavirus is recorded among the elderly. As it turned out, the whole point is in the features of B-lymphocytes – cells of the immune system, which are responsible for the production of antibodies against various types of pathogens.
“When a person is young, he has young cells that have a variety of abilities and are able to recognize almost everything that enters the body,” – explained the authors of the study. With age, there is no room for new B cells. Because of this, the body cannot provide an immune response to infection with an unknown virus. At the same time, according to scientists, B cells in the body are constantly replenished with new ones coming from the bone marrow. At the same time, the old ones turn into memory cells.
“We were able to detect a number of specific hormonal signals from old immune cells as well as memory cells that interfere with the production of new B cells in the bone marrow. This is a big discovery, because it can be compared to finding a needle in a haystack, ”the scientists said, explaining that this information will help find ways to slow down the aging process.
