Other immune cell subsets in tumors (Figure S4B,C, Supporting Information) and tumor‐draining lymph nodes (Figure S4D, Supporting Information) were also analyzed, including NK1.1+, CD11c+, and CD11b+ cells, but no differences were observed, highlighting the crucial role of CD8+ T cells in the PS‐induced anti‐tumor immune response. This evidence concerns the gene ITGAM and neoplasm.
