Are IL-8 and CXCL8 the same?
Interleukin 8 (IL-8 or chemokine (C-X-C motif) ligand 8, CXCL8) is a chemokine produced by macrophages and other cell types such as epithelial cells, airway smooth muscle cells and endothelial cells.
What causes IL-8?
Abstract. Interleukin-8 (IL-8) is a chemoattractant cytokine produced by a variety of tissue and blood cells. Unlike many other cytokines, it has a distinct target specificity for the neutrophil, with only weak effects on other blood cells. Interleukin-8 attracts and activates neutrophils in inflammatory regions.
Do mice produce IL-8?
However, mice do not have the IL-8 gene, so human cancer cell lines and xenograft studies have been used to study the role of IL-8 in colon and gastric carcinogenesis.
Do mice express IL-8?
What is the role of IL-8?
IL-8 is an important protein related to inflammation, where it plays a key role in the recruitment of neutrophils and other immune cells to the site of infection. In addition to macrophages, IL-8 is also released by epithelial cells, airway smooth muscle cells, and endothelial cells.
What are the ligands for CCR2?
Chemokine ligands for CCR2 CCR2 is activated by several chemokines, including CCL2 (formerly known as MCP-1), CCL7 (MCP-3), CCL8 (MCP-2), CCL12 (MCP-5, mouse only), CCL13 (MCP-4), and CCL16 (HCC-4, human only).
Is mouse CCL8 a chemokine?
Mouse CCL8 is a CC chemokine of the monocyte chemoattractant protein (MCP) family whose biological activity and receptor usage have remained elusive. Here we show that CCL8 is highly expressed in the skin, where it serves as an agonist for the chemokine receptor CCR8 but not for CCR2.
What is a knockout mouse?
Knockout mouse. Jump to navigation Jump to search. A knockout mouse or knock-out mouse is a genetically modified mouse (Mus musculus) in which researchers have inactivated, or “knocked out”, an existing gene by replacing it or disrupting it with an artificial piece of DNA.
How many knockout mice are used in experiments each year?
Millions of knockout mice are used in experiments each year. A knockout mouse (left) that is a model for obesity, compared with a normal mouse. There are several thousand different strains of knockout mice. Many mouse models are named after the gene that has been inactivated.
How do you make a homozygous knockout mouse?
White heterozygous mice can subsequently be crossed to produce mice that are homozygous for the knocked out gene. There are several variations to the procedure of producing knockout mice; the following is a typical example. The gene to be knocked out is isolated from a mouse gene library.
