Matured DCs can present tumor antigens to T cells and trigger subsequent immune responses.[26] Flow cytometry results demonstrated that the proportion of mature DCs (CD11c+CD80+CD86+) in the tumor draining lymph nodes (the main organ for DC maturation) was highest in the “APHP‐CCCA+808+660” group (Figure 4G; Figure S7A, Supporting Information) on day 15. Here, CD86 is linked to neoplasm.
