Abstract

Metabolism influences the behavior of various immune cell types. In a recent Cancer Cell study, Qiu et al. revealed mannose metabolism as a prominent metabolic feature of tumor precursor exhausted T cells (Tpex) that is crucial for maintaining T cell stemness. Their work uncovers a novel metabolic mechanism that decouples T cell proliferation from differentiation, providing valuable insights into how metabolic modulation can be used to generate "better" T cells during the manufacturing process.
