Recent studies have shown that PD‐L1 expression on both cancer cells and non‐cancer cells significantly influences patient outcomes.[23, 24, 25] Specifically, PD‐L1 signaling on CD8+ T cells can induce a nonreactive T‐bet‐IFN‐γ‐phenotype.[23] Therefore, we analyzed the relationship between Texterm cells and PD‐L1 expression on tumor cells vs immune cells using scRNA‐seq data. Here, CD274 is linked to cancer.
