This chemokine is secreted by a variety of cell types including monocyte\/macrophages, T cells, neutrophils, fibroblasts, endothelial cells, and various tumor cell lines in response to inflammatory stimuli. In human gliomas, IL-8 is expressed and secreted at high levels both in vitro and in vivo, and recent experiments suggest it is critical to glial tumor neovascularity and progression. Levels of IL-8 correlate with histologic grade in glial neoplasms, and the most malignant form, glioblastoma, shows the highest expression in pseudopalisading cells around necrosis, suggesting that hypoxia\/anoxia may stimulate expression. Accumulating evidence has demonstrated that various types of cells can produce a large amount of IL-8\/CXCL8 in response to a wide variety of stimuli, including proinflammatory cytokines, microbes and their products, and environmental chang. Numerous observations have established IL-8\/CXCL8 as a key mediator in neutrophil-mediated acute inflammation due to its potent actions on neutrophils. The discovery of these biological functions suggests that IL-8\/CXCL8 has crucial roles in various pathological conditions such as chronic inflammation and cancer.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Elabscience Biotechnology","offers":[{"title":"100μg","offer_id":40692718633018,"sku":"PKSH030278-100","price":798.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7785\/files\/recombinant-human-il-8-cxcl8-protein-aa-28-99-fc-tag-100-g-elabscience-biotechnology-cell-assays-22373213536314.jpg?v=1752498203","url":"https:\/\/www.msesupplies.com\/en-de\/products\/recombinant-human-il-8-cxcl8-protein-aa-28-99-fc-tag","provider":"MSE Supplies","version":"1.0","type":"link"}
