C-X-C motif chemokine 3 （CXCL3） also named Growth-regulated oncogene gamma （GROγ）, which is a chemokine of the intercrine alpha family. CXCL3 is a 8 kDa protein containing 73 amino acid residues. During inflammation, CXCL3 is activated by the TNF and IL-1 which mediates the monocytes migration and adhesion by targeting the CXCR2. CXCL3 activates the JNK activity which induce the cell differentiation.
