Effective CD8+ T cell immunity requires the generation of a long-lived memory pool and the maintenance of a non-exhausted effector T cell pool. The implementation of immune checkpoint blockade can reduced levels of exhaustion but lacks the ability to support memory formation in the effector pool. Here the authors suggest a role for Let-7 in the enhancement of the anti-tumor CD8+ T cell response by supporting memory via modulation of metabolic and differentiation state.
