Additionally, the double immunofluorescence staining method was applied to evaluate the immunosuppressive role of CD73 on tumor‐infiltrating cytotoxic CD8+ T cells and found that the numbers of tumor‐infiltrating Granzyme B+CD8+ T cells were reduced in the CD73‐overexpressed KPC tumors compared to controls (Figure S2H, Supporting Information). This evidence concerns the gene GZMB and neoplasm.
