BACKGROUND Interleukin-17A (IL-17A) is not only an important modulator of inflammatory reactions, but also affects bone metabolism, which is involved in osteogenic differentiation of stem cells. However, the role and mechanism of IL-17A in osteogenic differentiation of bone mesenchymal stem cells (BMSCs) are not fully understood. In this study, we investigated the role and mechanism of IL-17A i...
BACKGROUND Interleukin (IL)-17A and IL-17E (also known as IL-25) have been implicated in fibrosis in various tissues. However, the role of these cytokines in the development of intestinal strictures in Crohn's disease (CD) has not been explored. We investigated the levels of IL-17A and IL-17E and their receptors in CD strictured and non-strictured gut, and the effects of IL-17A and IL-17E on CD...
Interleukin-17A-producing T cells, especially Th17, have been shown to be involved in inflammatory autoimmune diseases and host defense against extracellular infections. However, whether and how IL-17A or IL-17A-producing cells can help protection against intracellular bacteria remains controversial, especially how it regulates the adaptive immunity besides recruitment of neutrophils in the inn...
OBJECTIVE Interleukin(IL)-17A, an inflammatory cytokine, has been implicated in atherosclerosis, in which inflammatory cells within atherosclerotic plaques express IL-17A. However, its role in the development of atheroscelrosis remains to be controversial. METHODS AND RESULTS To directly examine the role of IL-17A in atherosclerosis, we generated apolipoprotein E (ApoE)/IL-17A double-deficien...
Multiple components of the immune response are involved in the initiation, progression and persistence of atherosclerosis. Interleukin (IL)-17A is produced by a broad variety of leukocytes and plays an important role in host defense. IL-17A is also involved in the pathology of several autoimmune diseases mainly via the regulation of chemokine expression and leukocyte migration to the site of in...
BACKGROUND Recently, it was shown that interleukin-17A (IL-17A) is involved in the pathophysiology of reperfusion injury and associated with infarct size (IS) in experimental models of myocardial infarction. Our aim was to evaluate whether the IL-17A serum level and the IL-17A active fraction was correlated with IS in humans. METHODS 101 patients presenting with a ST-elevated Myocardial Infar...
INTRODUCTION Interleukin (IL)-17A is a cytokine originally reported to induce neutrophil-mediated inflammation and anti-microbial activity. The CD4+ T cells, which produce IL-17A, have been well characterized as Th17 cells. On the other hand, IL-17A-producing TCR γδ+ T cells have been reported to participate in the immune response at an early stage of infection with Listeria monocytogenes and M...
Interleukin 17A (IL-17A) is a proinflammatory cytokine responsible for the initiation and propagation of inflammation. One of its actions is the recruitment of neutrophils to the site of infection. The aim of this study was to investigate whether there is association between IL-17A expression and neutrophil infiltration in periapical abscesses and periapical granulomas, as well as to find which...
BACKGROUND Francisella tularensis is an intercellular bacterium often causing fatal disease when inhaled. Previous reports have underlined the role of cell-mediated immunity and IFNgamma in the host response to Francisella tularensis infection. METHODOLOGY/PRINCIPAL FINDINGS Here we provide evidence for the involvement of IL-17A in host defense to inhalational tularemia, using a mouse model o...
The expression of IL-17A and programmed death ligand 1 (PDL1) is increased in estrogen receptor-negative breast cancer. IL-17A promotes tumor cell survival and invasiveness and inhibits the antitumor immune response. The PDL1-PD1 (programmed death protein 1) signaling pathway promotes escape from immune surveillance in tumor cells. The pro-tumor properties of IL-17A and PDL1 in various cancers ...
