Autoimmune diseases are caused by loss of self-tolerance resulting in both humoral and cell-driven targeting healthy tissue immune cells. Different cytokines thought to drive different autoimmune skin (e.g. IL17 psoriasis, Type-I interferon cutaneous lupus erythematosus (CLE), Type-II vitiligo), yet similar cytokine signatures present across diseases. For a direct systematic comparison disease ...

Background A warning about appearance or worsening of inflammatory bowel disease (IBD) during treatment with anti-IL17 agents has been launched by regulatory agencies in the last years. This caution is based on relationship between (IBD), joint (spondyloarthritis [SpA]) and skin (psoriasis [Ps]); regarding immune aspects. As well, drugs have proved ineffective IBD treatment. [1,2] Objectives To...

Aberrant interferon gamma (IFNγ) expression is associated with the pathogenesis of numerous autoimmune- and inflammatory disorders, including inflammatory bowel diseases (IBD). However, the requirement of IFNγ for the pathogenesis of chronic intestinal inflammation remains controversial. The aim of this study was thus to investigate the role of IFNγ in experimental mouse models of innate and ad...

Reactive arthritis (ReA) is an inflammatory condition of the joints that arises following an infection. Salmonella enterocolitis is one of the most common infections leading to ReA. Although the pathogenesis remains unclear, it is known that IL-17 plays a pivotal role in the development of ReA. IL-17-producers cells are mainly Th17, iNKT, and γδT lymphocytes. It is known that iNKT cells regulat...

OBJECTIVE Although astrocytes participate in glial scar formation and tissue repair, dysregulation of the NFκB pathway and of nitric oxide (NO) production in these glia cells contributes to neuroinflammation and neurodegeneration. Here we investigated the role of the crosstalk between sphingosine-1-phosphate (S1P) and cytokine signaling cascades in astrocyte activation and inflammation-mediated...

Our aim was to compare bone gene expression in rheumatoid arthritis (RA) and primary osteoporosis (OP) patients. Secondary aims were to determine the association of gene expression of the Wnt/β-catenin signaling pathway with inflammatory cytokines in the bone microenvironment and to assess the serum levels of Wnt/β-catenin proteins in both groups. RA patients referred for hip replacement surger...

We analyzed cytokine responses against latent and lytic Epstein-Barr virus (EBV) antigens in systemic lupus erythematosus (SLE) patients and healthy controls (HCs) to obtain an overview of the distinctive immune regulatory response in SLE patients and to expand the previously determined impaired EBV-directed T-cell response. The concentrations of 14 cytokines (IL2, IL4, IL5, IL6, IL10, IL12, IL...

Th17 cells are a subset of CD4+ T cells with an important role in clearing certain bacterial and fungal pathogens. However, they have also been implicated in autoimmune diseases such as multiple sclerosis. Exposure of naive CD4+ T cells to IL-6 and TGF-β leads to Th17 cell differentiation through a process in which many proteins have been implicated. We report here that ectopic expression of li...

OBJECTIVE The present study aims to investigate the correlation between Interleukin (IL)-17 gene polymorphism with gastric cancer susceptibility in Han Chinese population. PATIENTS AND METHODS Between November 2013 and October 2014, 386 patients with gastric cancer who had undergone surgeries at our institution and 374 age- and sex-matched healthy controls were included in this study. Single ...

Infant formula and breastfeeding are environmental factors that influence the incidence of Type 1 Diabetes (T1D) as well as the acidity of newborn diets. To determine if altering the intestinal microbiome is one mechanism through which an acidic liquid plays a role in T1D, we placed non-obese diabetic (NOD)/ShiLtJt mice on neutral (N) or acidified H2O and monitored the impact on microbial compo...
