CD4 + immune cells in the body of people over 110 are 3-4 times more young people, capable of searching and destroying pathogenic cells.
The abnormal amount of CD4 + cells helps 7 people over 110 years of age to participate in the study.
In young and mature adults, CD4 + only helps to reduce infection. For people over 110 years of age, CD4 + has "toxicity" , which can search and destroy many viruses and cancer cells. This proves previous studies: people who are over 100 years old rarely suffer from cardiovascular diseases and cancer.
"This unique ability of CD4 + cells exists only in people who live outside a century," said Dr. Kosuke Hashimoto, the study author.
Normally, the older you get, the greater your risk of developing the disease because the T-cell structure gradually breaks down. The abnormal amount of CD4 + cells was concluded by Dr. Kosuke Hashimoto as a weapon to help 7 people over 110 years old to participate in the study without getting sick even when they are old.
"If there is a connection between the immune system, aging and longevity, it is likely that life expectancy will last longer in the future," Mr. Kosuke said.
