Description

The accumulation of neutrophil leukocytes in tissues is a major event in inflammation, a defensive reaction in response to injury or infection [PMID: 1639201]. Neutrophils are drawn in from the blood by chemotactic signals that direct their migration to the affected site. Interleukin-8 (IL8) is one such chemotactic protein: it is released by phagocytes, mesenchymal cells and a wide variety of tissue cells, upon exposure to inflammation; and it acts as a neutrophil-activating cytokine, inducing chemotaxis, exocytosis, and the respiratory burst.

IL-8 is a member of the CXC chemokine family. It attracts neutrophils, basophils, and T-cells, but not monocytes.
