Engineered T cells are used for tumour immunotherapy but can have side effects and need multiple treatment rounds. Here during expansion of T cells from patients, the authors use an inhibitor of the epigenetic regulator G9a/GLP and show that this increases T cell cytotoxic function and tumour reduction in vitro and in vivo respectively.
