Flow cytometry analysis revealed that combination treatment with H151 and TZ‐dSA3‐12 reduced tumor‐infiltrating CD8+ T cells (Figure S7f, Supporting Information) and diminished GzmB and IFN‐γ production compared to TZ‐dSA3‐12 treatment group (Figure S7g, h, Supporting Information). Here, GZMB is linked to neoplasm.
