Three days post-treatment, CODEX imaging of the tumors indicated immune infiltration (CD45), tumor inflammation (H2Kb, PDL1), and downregulation of tumor proliferation (Ki67) from both T cell-treated tumors compared to the control tumor not treated with T cells (referred to as No T cells) (Figures 4A and 4B, n = 4–7). Here, PTPRC is linked to neoplasm.
