Memory T cells can be maintained for a lifetime, but the underlying mechanism has been hard to pin down. A new study identifies a subset of memory T cells with stem cell properties in humans and shows that these cells mediate a superior antitumor response in a mouse model of adoptive T cell therapy (pages 1290–1297).
