    SATB1 is downregulated during the differentiation of Tpex cells to Tex-int cells in the tumor microenvironment.

  • 2

    Genetic ablation of Satb1 in T cells significantly expands tumor-infiltrating CD8+ T cells.

  • 3

    Ablating Satb1 promotes Tex-int cell differentiation from Tpex cells and remodels T cell differentiation in tumor-draining lymph nodes.

  • 4

    Early-stage Tex-int cells in Satb1-deficient mice show transient functional impairment, which resolves in late-stage tumors.

  • 5

    Targeting SATB1 may enhance cancer immunotherapy by expanding the Tex-int population.
