Flow cytometry assays to analyze the status of tumor-infiltrating natural killer cells (NKs) and dendritic cells (DCs) in the B16 model. The representative images of tumor-infiltrating a NKs, b Ki67⁺ NKs, c CD107a⁺ NKs, d TNF-α⁺ NKs, e Perforin⁺ NKs, and f DCs. *p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001 denote the significant difference relative to combination treatment
