Abstract

The present disclosure relates to genetically modified T cells comprising a transgene encoding an engineered antigen specific receptor, wherein expression of an endogenous gene selected from MNK1, MNK2, or both are inhibited in the genetically modified T cell in order to enhance central memory T cell subsets in cellular immunotherapy compositions.
