Age Is Just a Number: Immune Cells’ Epigenetic Clock and Life Expectancy

Scientists at St. Jude Children’s Research Hospital and the University of Minnesota have studied the unique “epigenetic clock” of T-cell aging, showing that T-cells can outlive the body by at least four lifetimes. The main function of T-cells is recognition of antigens, the formation and response of effector immune response, and immunological memory. The results…
