IL-17A and IL-17F regulate granulopoiesis and are produced by memory T cells. Rag1(-/-) recombinase-activating gene-deficient mice cannot produce mature T cells but maintain normal neutrophil counts. Athymic nude mice are neutropenic or have near-normal neutrophil counts, depending on the prevailing intestinal flora, and do not produce IL-17A. By contrast, thymi from Rag1(-/-) mice contain as m...
Primary hyperparathyroidism (PHPT) is a common cause of bone loss that is modeled by continuous PTH (cPTH) infusion. Here we show that the inflammatory cytokine IL-17A is upregulated by PHPT in humans and cPTH in mice. In humans, IL-17A is normalized by parathyroidectomy. In mice, treatment with anti-IL-17A antibody and silencing of IL-17A receptor IL-17RA prevent cPTH-induced osteocytic and os...
BACKGROUND Viral infections are the most frequent cause of asthma exacerbations and are linked to increased airway reactivity (AR) and inflammation. Mice infected with respiratory syncytial virus (RSV) during ovalbumin (OVA)-induced allergic airway inflammation (OVA/RSV) had increased AR compared with OVA or RSV mice alone. Furthermore, interleukin 17A (IL-17A) was only increased in OVA/RSV mic...
RATIONALE One-third of myocarditis cases progresses to dilated cardiomyopathy (DCM), but the mechanisms controlling this process are largely unknown. CD4(+) T helper (Th)17 cells have been implicated in the pathogenesis of autoimmune diseases, but the role of Th17-produced cytokines during inflammation-induced cardiac remodeling has not been previously studied. OBJECTIVE We examined the impor...
In carcinogenesis, inflammasomes may play contradictory roles through facilitating anti-tumor immunity or inducing oncogenic factors. Their function in cancer remains poorly characterized. In this study, we explored the effect of interleukin-17A (IL-17A) on the migration and invasion activity of nasopharyngeal carcinoma (NPC) cell lines and account for related mechanisms. Our results revealed t...
BACKGROUND T cells play an important role during the immune response that accompanies atherosclerosis. To date, the role for interleukin (IL)-17A in atherogenesis is not well defined. Here, we tested the hypothesis that atherosclerosis-prone conditions induce the differentiation of IL-17A-producing T cells, which in turn promote atherosclerosis. METHODS AND RESULTS IL-17A was found to be elev...
T(h)17 cells represent a new pro-inflammatory T(h) cell lineage distinct from T(h)1 and T(h)2 cells. T(h)17 cells have been shown to be involved in extracellular bacterial infection but their role in intracellular infection remains unclear. We found antigen-specific IL-17A production during a systemic infection of mice with the facultative intracellular bacterium Salmonella enterica serovar Ent...
BACKGROUND Sepsis-associated acute kidney injury (SA-AKI) is an independent risk factor for death in patients with sepsis, but treatment for it is limited. To improve the diagnosis and treatment of SA-AKI, we must first understand its pathogenesis. Recently, interleukin (IL)-17A has been shown to be associated with the pathogenesis of acute kidney injury and sepsis, but its role in SA-AKI remai...
سابقه و هدف: بیماری های پریودنتال شامل یک سری پاسخ های التهابی مزمن بافت لثه می باشند که توسط میکروارگانیسم های پریودنتوپاتیک آغاز و از طریق تحریک سیستم ایمنی، موجبات آسیب بافت را فراهم می آورند. در بیماری های خودایمنی، التهابی و به ویژه بیماری های تخریب کننده بافت استخوان، به نقش سایتوکاین il-17a و پروتئین rankl (receptor activator for nuclear factor κb ligand) اشاره شده است ولی نقش دقیق آنها ...
Interleukin-17 (IL-17A) is a pro-inflammatory cytokine that has recently been implicated in pathogenesis of Langerhans Cell Histiocytosis (LCH), a potentially fatal disease characterized by lesions including CD207+ (langerin +) histiocytes. However, in this study we were unable to identify IL-17A gene expression in Langerhans cell lesions, and plasma levels of IL-17A did not correlate with dise...
