Manipulating PTPN2 has potential for advancing immunotherapies. However, it is unclear how PTPN2 impacts the activation, survival, and memory formation of T cells. Flosbach et al. demonstrate that PTPN2-deficient T cells are less dependent on cytokines and show increased programmed expansion, and short-lived effector T cells have enhanced survival and expansion capacity.
