CSF1R and infection: In addition, inflammatory monocytes were closely clustered with both resident monocytes and “L‐DC.” Genes commonly expressed at high levels across “L‐DC” and both monocyte subsets included Itgam, Cx3cr1, Csf1r, Itgb2, Ccl6, IL1b, Ccl3, Cdc42, Ptprc, CD244 and IL2rg. Itgam encodes CD11b, a common marker of myeloid cells which mediates the inflammatory response by regulating adhesion and migration of cells to sites of infection.46, 47Cx3cr1 encodes a marker common to cells of the myeloid lineage.48, 49, 50
