Human Interleukin17C (IL17C) ELISA Kit

Cytokine that plays a crucial role in innate immunity of the epithelium, including to intestinal bacterial pathogens, in an autocrine manner. Stimulates the production of antibacterial peptides and proinflammatory molecules for host defense by signaling through the NF-kappa-B and MAPK pathways. Acts synergically with IL22 in inducing the expression of antibacterial peptides, including S100A8, S100A9, REG3A and REG3G. Synergy is also observed with TNF and IL1B in inducing DEFB2 from keratinocytes. Depending on the type of insult, may have both protective and pathogenic properties, either by maintaining epithelial homeostasis after an inflammatory challenge or by promoting inflammatory phenotype. Enhanced IL17C/IL17RE signaling may also lead to greater susceptibility to autoimmune diseases.

1. Inflammatory cell expression of IL-9 and IL-17C were increased in chronic rhinosinusitis, particularly with allergy and asthma. These interleukins may contribute to the pathogenesis of chronic rhinosinusitis with nasal polyps as well as atopy and may serve as therapeutic targets for disease management PMID: 26989880
2. Helicobacter pylori infection was associated with a significant increase in IL-17C expression in gastric mucosa. The role of IL-17C in the pathogenesis of H. pylori-induced diseases remains to be determined. PMID: 28739826
3. Data indicate that epithelial IL-17C promotes neutrophilic inflammation in the tumor microenvironment and suggest that IL-17C links a pathologic microbiota, as present in COPD patients, with enhanced tumor growth. PMID: 28346430
4. CpG methylation is reduced in gingival biopsies of patients with periodontitis PMID: 26472015
5. Those carrying rs3748067 CC genotype and C allele had a significantly increased risk for the development of gastric cancer PMID: 25012243
6. IL-17C is an essential epithelial cell-derived cytokine. PMID: 23944933
7. Our study provides evidence that Staphylococcus aureus activates NOD2 in keratinocytes, resulting in an increased expression of IL-17C, a mechanism that may be dysregulated in atopic dermatitis. PMID: 23892590
8. Interleukin-17C is present in the tissue around aseptic loosened implants. PMID: 23474800
9. IL-17C is involved in the innate immune response of respiratory epithelial cells and is suppressed by cigarette smoke. PMID: 23221046
10. Data suggest that activation of TLR5 upregulates IL17C expression in cells from intestinal mucosa and colonic adenocarcinoma; IL17C expression is upregulated in intestinal mucosa cells from patients with ulcerative colitis compared with normal cells. PMID: 22994872
11. Keratinocyte overexpression of IL-17C promotes psoriasiform skin inflammation. PMID: 23359500
12. In our pilot study, we discovered significant changes in methylation patterns of genes IL-7, IL-13, IL-17C and TYK2 between henodialysis patients and healthy subjects PMID: 22506826
13. IL-17C is an essential autocrine cytokine that regulates innate epithelial immune responses. PMID: 21993848
14. activation of NF-kappaB (p65/p50) is crucial for the TNFalpha-induced stimulation of IL-17C expression in human keratinocytes PMID: 21628458
15. expressed in multiple sclerosis brain lesions PMID: 11984595
