The secret of being over 100 years old could be in your immune system, suggests a new study.
In a recent study published in Proceedings of the National Academy of Sciences (PNAS), scientists found that supercentenarians – those who are 110 years old from the age of 30 – have an oversupply of a certain type of disease-fighting cells in her immune system, which may explain her longevity.

In the "circulating immune cells" of supercentenarians and controls aged 50 to 89 years, approximately 41,208 immune cell samples were taken from seven supercentenarians, while 1
The study revealed that supercentenists and controls did so. The former group had a total of about the same amount of T cells and had an excess of a certain subset of T cells called cytotoxic CD4 T cells were. These cells are aggressive according to a press release and quickly destroy cancer and infection-causing cells.
In some cases, the cytotoxic CD4 T cells accounted for 80 percent of the supercentenary T cells, while only 10 to 20 percent of the T cells in the controls were cytotoxic CD4 T cells performed by the RIKEN center for Integrative Medicine (IMS) and the Keio University School of Medicine in Japan.

The cells of the "super" immune system are probably not a marker of youth, but "a special feature of the supercentenarians," the researchers wrote. The cytotoxic CD4 T cells are probably the progeny of a single "ancestral cell."
"We believe that this cell type, which is relatively rare in most individuals, including young, is useful for controlling established tumors and may be important for immune surveillance," said Piero Carninci, deputy director of RIKEN in a statement. "This is exciting as we gain new insights into how people with a very long life can protect themselves from diseases such as infections and cancer."
