The experts were able to determine which lymphocytes predominate superdolgozhiteley – those who turned 100 years or more.
Japanese scientists from the Center for integrative medicine RIKEN and Keio University have determined that people who live long, there is excess immune cells of a certain type. This is what makes people live to 100 years or more immune to infections and cancer.
The experts analyzed samples of immune cells from the seven centenarians who are over 100 years old, and five people aged 50 to 80 years.
Researchers found out that people at the age of 110 years there is an increased number of cytotoxic T-lymphocytes.
On the surface identified by cytotoxic T-lymphocytes are CD4 immunoglobulins. Blood superdolgozhiteley these cells accounted for 80 percent of all other T cells compared to 10-20 percent in the control samples. Typically are cytotoxic cells with CD8 immunoglobulin.
According to experts, CD4 T-lymphocytes is inherent in the people living over 100 years.
