It is now becoming clear that less differentiated naive and memory T cells are superior to effector T cells in the transfer of immunity for adoptive cell therapy. This review will outline the challenges faced by chimeric antigen receptor (CAR) T cell therapy in the generation of persistence and memory for CAR T cells, and summarize recent strategies to improve CAR T cell persistence, with a focus on memory cell formation. The relevance of enhancing persistence in more differentiated effector T cells is also covered, because genetic and pharmacological interventions may prolong effector T cell activity and lifespan, thereby improving anti-cancer activity. In particular, it may be possible to enforce epigenetic changes in differentiated T cells to enhance memory CAR T cell formation. Optimizing the generation of self-renewing T cell populations (e.g. memory cells), while maintaining differentiated effector T cells through epigenome modification, will help overcome barriers to T cell expansion and survival, thereby improving clinical outcomes in CAR T cell therapy.
