RNAseq of wild-type and VHL-deficient CD8+ subsets

Adoptive T cell therapies hold great promise in cancer treatment, but low overall response rates in patients with solid tumors underscore remaining challenges in realizing the potential of this cellular immunotherapy approach. Promoting CD8+ T cell adaptation to tissue residency represents an underutilized but promising strategy to improve tumor-infiltrating lymphocyte (TIL) function. Using mice lacking von Hippel Lindau (VHL) in CD8+ T cells and RNA-sequencing (RNA-seq), we identified tissue-resident memory (TRM)-like TIL in mouse models of malignancy. Additionally, we found that VHL-deficient TIL exhibited a core TRM signature despite an exhaustion-associated phenotype. These results reveal a key role for VHL/HIF axis in controlling the formation of a TRM CD8+ T cell subset in primary and secondary tumors that resists functional exhaustion and mediates strong anti-tumor responses. Overall design: 8 samples, 2-3 biological replicates with five mice each, Spleen and TIL CD8+ T cell subsets
