Scientists Found a Possible Reason Some People Live Beyond 100
Supercentenarians, a.k.a. people who live beyond 100, might have their superpowered, anti-cancer-fighting immune systems to thank. According to research published in Cell Reports, people who make it past 100 appear to develop more of a rare type of immune cell that helps fend off cancer and other cellular troubles. Researchers at Osaka University studied blood […] The post Scientists Found a Possible Reason Some People Live Beyond 100 appeared f…
What helps very old people achieve longevity? According to one study, an unusual type of immune cell could play a role.
As people age, their immune systems typically weaken. But research on centenarians aged 100-110 shows a surge in a group of rare CD4 T cells, suggesting the immune system may be quietly adapting to fight off abnormal cells.
The average lifespan of modern humans is about 71 years, with a small number reaching 100 years old, and those who live past 110 are even rarer, known as "supercentenarians." According to a study published in the journal *Cell Reports*, Osaka University in Japan...
People over 100 have unusually high levels of tumor-killing T cells, which may contribute to their exceptional longevity.
