Where this comes from

Abstract

When T cells respond to infectious agents, they differentiate into effector and memory cells. In this issue of Cell, Smith et al. use a genetic "time-stamping" method to show that the developmental time the T cell arises-near birth or as an adult-dictates what type of T effector or memory cell results.
