Furthermore, we examined the correlation between CX3CR1 expression and immune markers of different immune cells using the correlation module of the TIMER database in COAD, including monocyte markers (CD86 and CSF1R), tumor-associated macrophage (TAM) markers (CCL2, CD68, and IL10), M1 macrophage markers (NOS2, IRF5, and PTGS2), and M2 macrophage markers (VSIG4, MS4A4A, and CD163). This evidence concerns the gene CD163 and neoplasm.
