Analyses of tumor-bearing brains by us and others have shown that the infiltrating CD45+CD11b+ population includes CD11b+ conventional DCs (cDCs), monocytes, monocyte-derived DCs induced by inflammation (moDCs), and macrophages; CD45+CD11c+CD11b− cells include plasmacytoid DCs (pDCs) and CD11b− cDCs; and CD45+ CD11b−CD11c−MHCII+ cells comprise B cells primarily. This evidence concerns the gene PTPRC and neoplasm.
