Scientists at the University of Tel Aviv in Israel have for the first time slowed down the aging of the human immune system with hyperbaric oxygen therapy, which increases the length of telomeres and increases the body’s ability to get rid of damaged cells. An article with the results of scientific work was published in the journal Aging.
The study involved 35 people aged 64 and older who received a course of 60 daily sessions of hyperbaric oxygen therapy. At the 30th and 60th session, as well as 1-2 weeks after the end of the course, scientists collected blood samples from volunteers and assessed the length of telomeres of mononuclear cells (various immune cells) and the severity of signs of aging.
It turned out that oxygen therapy led to an increase in telomere length in T-helpers, cytotoxic T-lymphocytes, natural killer cells and B-cells by more than 20 percent. The most significant changes were observed in B cells, in which telomere length increased by 37 percent by the end of the study. There was a 37 percent and 10 percent reduction in senescent helper T cells and cytotoxic lymphocytes, respectively.
