In order to understand the reasons for such a life expectancy, scientists have tracked how
Further, this information was compared with the work of the immunity of humans and mice of the same age.
So it turned out that the body of the mole rats had very few "adult" T cells and B cells, which are responsible for maintaining long-term immunity and the production of antibodies to already familiar pathogens.
Both are completely uncommon in other mammals that develop long-term immunity and gradually lose most of the old T cells and B cells as they mature.
The authors believe that this feature protectsmole rats from the formation of a large number of immune cells, during the maturation of which errors occurred, as a result of which they begin to attack the cells of the body itself or cause chronic inflammation.
