Mammals with more sustainable immunity live longer than their relatives – scientists from Bat University have reached this conclusion. Published in İş Magazine Scientific Reports (SR).
Researchers have analyzed and learned 46 types of mammals: The maximum potential life expectancy (ie, the maximum registered age of the individual) is closely related to the number of genes responsible for immune protection. Such genes help the body to cope with infections, remove damaged cells and prevent the development of tumors.
The authors draw attention to the fact that long -lasting animals – for example, whales and dolphins – not only a large brain, but also their immune genes expand their families. However, even species with a small brain such as naked digesters or bats live for a long time if they increase immunity.
Therefore, not only individual mutations, but also large -scale changes in the genome – such as the reproduction of all gene genes – play an important role in the evolution of longevity.
The author of the business. Benjamin Padilla-Morales said, “It was already known that the size of the brain is related to life expectancy. We have shown that the immune system is an equally important factor.” – “These two mechanisms developed together, provided survival and longevity.”
Now researchers plan to examine genes associated with oncological diseases to understand how they fully affect life expectancy.
Previously, scientists discovered Tomatoes have a “rejuvenation” mechanism similar to human beings.
