PTPRC and neoplasm: Monocytic myeloid‐derived suppressor cells (Mo‐MDSC) and tumor‐associated macrophages (TAMs) are generally considered immunosuppressive cell populations in the immunosuppressive tumor microenvironment (TME) and contribute to tumor immune evasion.[29] In contrast with increased T cells, tumor‐infiltrated Mo‐MDSC (CD45+CD11b+Ly6C+Ly6G−) and TAMs (CD45+CD11b+F4/80+) levels were reduced in the 8FNs‐treated group compared to the PBS group (Figure 4K,L).
