Since chemokines and cytokines including CCLs (chemokine (C-C motif) ligands), CXCLs (Chemokine (C-X-C motif) ligands), EGF and CSFs (Colony stimulating factors) are important drivers for macrophage recruitment 27, 28, we examined their expression in tumor cells upon ILT4 knockdown. The gene discussed is EGF; the disease is neoplasm.
