BACKGROUND Interleukin-8 (IL-8, CXCL8) is a potent chemoattractant for neutrophils and contributes to acute liver inflammation. Much less is known about IL-8 in chronic liver diseases (CLD), but elevated levels were reported from alcoholic and hepatitis C-related CLD. We investigated the regulation of IL-8, its receptors CXCR1 and CXCR2 and possible IL-8 responding cells in CLD patients. METH...

PURPOSE To determine the effects of the potent anti-inflammatory Th2 cytokines, interleukin (IL)-4, -10, and -13, on IL-8 and monocyte chemoattractant protein (MCP) 1 production by human retinal pigment epithelial (HRPE) cells, monocytes, and HRPE cell-monocyte cocultures. METHODS Enzyme-linked immunosorbent assays were performed to determine IL-8 and MCP-1 secretion by HRPE cells, monocytes,...

Interleukin-8 (IL-8) is a major neutrophil chemoattractant and functional stimulant that is induced by IL-1, tumor necrosis factor alpha (TNF alpha), and lipopolysaccharide (LPS). We report that recombinant human (rh) granulocyte-macrophage colony-stimulating factor (GM-CSF) and rhIL-3 are also potent inducers of IL-8 messenger RNA (mRNA) accumulation and protein secretion by normal peripheral ...

In highly purified human polymorphonuclear leukocyte (PMN) preparations containing less than 0.1% contaminating monocytes, significant amounts of interleukin-8 (IL-8) and small amounts of IL-la, IL-la, and tumor necrosis factoralpha (TNF-a) were produced by lipopolysaccharide (LPS) stimulation. Contrary to published reports, IL-6 production could not be detected. IL-10 inhibited the produc...

henoch–schönlein purpura (hsp), a common allergic hemorrhagic disease, occurs frequently in children affecting kidney, joint and skin. while interleukin-8 (il-8) plays an important role in inflammation, the association between il-8 gene +781 c/t polymorphism and hsp remains unclear. interleukin-8, an important chemokine related to the initiation and amplification of acute inflammatory responses...
