The protein encoded by this gene is a member of the CXC chemokine family. This chemokine is one of the major mediators of the inflammatory response. This chemokine is secreted by several cell types. It functions as a chemoattractant, and is also a potent angiogenic factor. This gene is believed to play a role in the pathogenesis of bronchiolitis, a common respiratory tract disease caused by viral infection. This gene and other ten members of the CXC chemokine gene family form a chemokine gene cluster in a region mapped to chromosome 4q.



IL-8 is a chemotactic factor that attracts neutrophils, basophils, and T-cells, but not monocytes. It is also involved in neutrophil activation. It is released from several cell types in response to an inflammatory stimulus. IL-8(6-77) has a 5-10-fold higher activity on neutrophil activation, IL-8(5-77) has increased activity on neutrophil activation and IL-8(7-77) has a higher affinity to receptors CXCR1 and CXCR2 as compared to IL-8(1-77), respectively.


Several N-terminal processed forms are produced by proteolytic cleavage after secretion from at least peripheral blood monocytes, leukcocytes and endothelial cells. In general, IL-8(1-77) is referred to as interleukin-8. IL-8(6-77) is the most promiment form.

Citrullination at Arg-27 prevents proteolysis, and dampens tissue inflammation, it also enhances leukocytosis, possibly through impaired chemokine clearance from the blood circulation.

Application: WB    Species: Human    Sample: HUVECs

Fig. 3 Effects of inhibition of HIF-1α on expression of inflammation after hyperglycemic and hypoxia. a Cells were treated with glucose (25 mM) or with combined exposure to high glucose and hypoxia for 6, 12, 24, and 48 h. Exposure to glucose alone or combined stimulation with hypoxia significantly increased gene expression of HIF-1α. b Cells were treated with KC7F2 (10 µM) or si-HIF-1α for 48 h following combined stimulation, and IL-6, IL-8, ICAM-1, MCP-1, and c HIF-1α levels were analyzed. The relative density of IL-6, IL-8, ICAM-1, and MCP-1 (d) was normalized according to GAPDH expression. Importantly, the downregulation of HIF-1α decreased the secretion of IL-6, IL-8, ICAM-1 and MCP-1 based on ELISA and qRT-PCR assays (e–f). n = 3; *p < 0.05 and **p < 0.01 vs. DMSO.

The level of IL-8 in the HA-GEL group was significantly lower than that in the other two groups at day 7 (p < 0.05). On day 3, both alginate and HA-GEL groups could significantly reduce the expression of MCP-1. On day 7, the level of MCP-1 in the HA-GEL group remained significantly lower than that in the alginate group and control.
