产品详细信息Description: IL-17F is a 37kD homodimer of the IL-17 family and a signature Th17 marker. Of all the six IL-17 family members, IL-17F and IL-17A share the strongest homology (50% amino acid identity), and the two genes are located in the same chromosomal region. Recent studies have demonstrated coordinated regulation of IL-17A and IL-17F during Th17 differentiation. Expression of IL-17F and IL-17A has been detected in activated human peripheral blood lymphocytes, specifically by activated human CD4+ T cells. In addition to IL-17A, differentiated Th17 cells also produce IL-17F and IL-22 upon re-activation. Like IL-17A, IL-17F has been linked with inflammatory diseases. IL-17F and IL-17A expression has been observed in tissue samples from various autoimmune diseases, such as rheumatoid arthritis, multiple sclerosis, psoriasis, inflammatory bowel disease, and asthma. IL-17F treatment of airway epithelium, vein endothelial cells, and fibroblasts has been reported to induce expression of IL-6, IL-8, CXCL1, ENA-78, TGF beta, MCP-1, G-CSF, GM-CSF, and ICAM-1.Like IL-17A, IL-17F is a disulfide-linked homodimeric glycoprotein. The IL-17F homodimer includes a classical cysteine knot motif, which is found also in the TGF beta, BMP, and NGF superfamilies. The presence of the cysteine knot motif suggested the possibility of a heterodimeric structure, as was reported for TGF-\beta and inhibin/activin. Recent reports confirm that co-expression of IL-17F and IL-17A in HEK293 cells results in the formation of biologically active IL-17F/IL-17A heterodimers, in addition to the IL-17F homodimers and IL-17A homodimers. Moreover, activated human CD4+ T cells were found to produce the IL-17A/F heterodimer, along with the corresponding homodimers. In comparing the relative potency of IL-17A, IL-17F, and IL-17A/F, all three were found to induce CXCL1 secretion; IL-17A was most potent, followed by IL-17A/F heterodimer, then IL-17F (100fold lower than IL-17A). In the mouse, the IL-17A/F heterodimer (alone or in synergy with TNF-alpha) was found to regulate the expression of IL-6 and KC (mouse homolog of human CXCL1); this was found to be dependent on IL-17RA and TRAF6.Applications Reported: The intended application of the Mouse IL-17F Single-Use ELISA RSG Standard is as a standard for the Mouse IL-17F ELISA (cat. 88-7472). Typically the standard is run in a series of 7 doubling dilutions from the 'top' standard. Please refer to the Certificate of Analysis included with each ELISA set for instructions on the proper dilution of the recombinant standard.Note: These are single-use vials. Use one time and discard. Dilute as suggested in the Certificate of Analysis, not difficult-to-measure fractions of the suggested volumes or recovery may not be accurate. Use within 6 hours of dilution to top standard concentration.Applications Tested: Mouse IL-17F Single-Use ELISA RSG Standard is reported for use in Mouse IL-17F ELISA Ready-SET-Go!® (cat. 88-7472).Storage and handling: For best recovery, quick-spin vial prior to opening. For dilution of current stock, use ELISA Assay Diluent.靶标信息IL-17F (Interleukin 17F, CTLA-8)) is a cytokine belonging to the IL-17 family that is produced by inflammatory cells such as activated T cells, mast cells, and basophils. IL-17F is involved in allergic airway inflammation, and can induce several cytokines, chemokines, and adhesion molecules in bronchial epithelial cells, vein endothelial cells, fibroblasts, and eosinophils. IL-17F may be secreted as a homodimer, or a heterodimer with IL17A. It acts by binding to the type I receptor, IL-17R, aiding recruitment of monocytes and neutrophils at the site of inflammation by increasing chemokine production. IL-17F also stimulates induction of other pro-inflammatory cytokines TNF alpha, IL-1 beta, IL-6, and IL-8, and reports strongly suggest the involvement of IL-17 in several chronic inflammatory diseases such as rheumatoid arthritis, psoriasis and multiple sclerosis. TGF-beta (differentiation) and IL-23 (expansion) are required for induction and maintenance of Th17 (IL-17 producing) cells, which in turn induce the other pro-inflammatory cytokines. IL-17F is produced, and exists, as a homo-dimer, with homology to a herpes virus early protein, is one of the six members (IL-17A-F) of this cytokine family, and is well characterized and highly expressed by activated effector memory T cells. IL-17F has been found to inhibit the angiogenesis of endothelial cells and induce endothelial cells to produce IL2, TGFB1/TGFB, and monocyte chemoattractant protein-1.
