CD163 and neoplasm: This further enhanced the recruitment of myeloid inflammatory cells, including neutrophils (Ly6B+), MDSCs (CD11b+Gr‐1+), and macrophages (F4/80+CD163+), in pre‐irradiated mouse brains bearing tumor; this recruitment was uniformly decreased in response to ABT263 or D+Q treatment or knockdown of CXCL1 (Figure 7H,I,J; Figures S8B,C,D and S9A,B,C, Supporting Information).
