Specifications

CXCL3 is also known as MIP­2 (macrophage inflammatory protein 2 beta), or DCI P­1 (dendritic cell inflammatory protein­1) in mouse, CINC2 (cytokine­induced neutrophil attractant 2) in rat, and GRO­ (growth­regulated oncogene gamma) in humans (1, 2) . It is an 8kD proinflammatory member of the CXC subfamily of heparin­binding chemokines, also called alpha chemokines (1­4) . The Glu­Leu­Arg (ELR) motif near the CXCL3 N­ terminus confers angiogenic properties and distinguishes it from interferon­inducible ELR­ CXC chemokines, which are angiostatic (4). ELR+ and ELR­ chemokines use CXCR2 and CXCR3 receptors, respectively (3, 4). Mature mouse CXCL3 shares 88% and 57% amino acid (aa) sequence identity with rat and human CXCL3, respectively. Among mouse ELR+ chemokines, it shares 82% aa sequence identity with CXCL2/GRO­ / MIP­2 and 34% ­ 58% with CXCL1/GRO­ / KC, CXCL5/ENA­78 and CXCL7/NAP­2. Due to their similar sequence and activity, CXCL2 and CXCL3 are sometimes referred to collectively as CXCL2/ 3, but are separate gene products (4 ­ 6). Mouse CXCL3 expression is induced in macrophages and early in maturation of DC by bacterial products such as lipopolysaccharides, and other inflammatory mediators (1, 7) . It is chemotactic for CXCR2­expressing neutrophils, helping to recruit them to areas of inflammation (1, 7). ELR+ chemokines also elicit endothelial cell chemotaxis, stimulating angiogenesis and playing a role in tumor development (3, 4). ELR+ chemokines upregulated by ischemi a play a role in ischemia­reper fusion injury (5, 6) . A decoy receptor , DARC (Duffy antigen receptor for chemokines) competes with CXCR2 for ELR+ chemokine binding, thus downregulating their effect (8). Neutrophil influx may also be downregulated by MMP­12, which has been found to inactivate CXCL3 and other ELR+ chemokines by cleaving them at the ELR site (9).
