Immune cells, including neutrophils, are recruited to the site of infection by chemokines such as CXCL8 (Interleukin-8) and CCL3 (macrophage inhibitory protein-1alpha-MIP1α) and other inflammatory stimuli including the bacteria-derived N-formyl-methionyl-leucyl-phenylalanine (fMLP). This evidence concerns the gene CCL3 and infection.
