BayeSpace‐enhanced spatial data revealed the abundant infiltration of T cells (CD3D, IL7R), B cells (MS4A1, MZB1), and cytotoxicity markers (GZMK) throughout tumor sections of HT samples, presenting an “immune‐activation” TME after HAIC therapy (Figure 4C; Figure S5B, Supporting Information). This evidence concerns the gene GZMK and neoplasm.
