BACKGROUND Uveitis is an eye inflammatory disease, which is sometimes associated with underlying systemic disease. Interleukin-23 plays an important role in autoimmune disease. The aim of this meta-analysis was to evaluate the association between the interleukin-23 receptor (IL-23R) and susceptibility to uveitis. METHODS Published literature from PUBMED and EMBASE were retrieved. Seven studie...

Foxp3- and ROR gamma t-expressing cells are involved in acquired immune responses. The change in Foxp3 and ROR gamma t expression in lung tissue and their role in emphysema has not been studied for COPD patients and normal smokers. In the present study, Foxp3 and ROR gamma t were assessed using real-time quantitative polymerase chain reaction and western blotting, and the expression and distrib...

Multiple sclerosis is among the most serious inflammatory demyelinating diseases (IDD). Interleukin-23A (IL23A) regulates and coordinates the activities of immune cells by interacting with its receptor IL23R and plays key roles in the pathogenesis of immune inflammatory diseases. IDD, deemed to be a kind of autoimmune diseases, may involve IL23A in the pathogenesis. The aim of this work was to ...

Allergic asthma is a chronic airway disorder characterized by airway inflammation, mucus hypersecretion, and airway hyperresponsiveness (AHR). A murine model of asthma was used to examine the antiasthmatic effect of inhaled inactived Mycobacterium phlei (M. phlei). AHR, neutrophil levels, eosinophil levels and levels of interleukin (IL)‑17 and IL‑23 receptor (IL‑23R) were monitored. The results...

67 www.ijntr.org Abstract—Genome-wide association studies of psoriasis identified interleukin (IL)-12B and IL-23R as significantly associated loci with psoriasis, thus emphasizing to the important role of these genes in the pathogenesis of this disease and have influenced the development of medications that specifically target these key immunological players. Here we report an association study...

A proinflammatory cytokine, interleukin 23 (IL-23), plays a role in tumor progression by inducing inflammation in the tumor microenvironment, although there is debate about its role in carcinogenesis. Direct effects of IL-23 on tumor cells have been reported rarely, and contradictory effects have been observed. Here, we studied such effects of IL-23 in lung cancer cells in vitro and in vivo and...

BACKGROUND Human Immunodeficiency Virus (HIV) and Schistosomiasis co-infection is common among residents at the shores of Lake Victoria in Kenya. About 36% of this population initiating antiretroviral therapy (ART) experience Immune Reconstitution Inflammatory Syndrome (IRIS) that complicates recovery. Several IL-23R alleles have been associated with susceptibility to both autoimmune and inflam...

BACKGROUND AND PURPOSE Interleukin (IL)-23 is a cytokine in the IL-12 family, mainly produced by antigen-presenting cells with a central role in inflammation. We hypothesize that IL-23 is also important in atherogenesis and investigate this in a population with carotid atherosclerosis. METHODS Plasma levels of IL-23 were measured in patients with carotid artery stenosis and in healthy control...

IL-17-producing CD4(+) T (Th17) cells, along with IFN-γ-expressing Th1 cells, represent two major pathogenic T cell subsets in experimental autoimmune encephalomyelitis (EAE), the animal model of multiple sclerosis (MS). The cytokines and transcription factors involved in the development and effector functions of Th1 and Th17 cells have been largely characterized. Among them, IL-23 is essential...

Interleukin (IL)-17 plays a key role in immunity. In acute infections, a rapid IL-17 response must be induced without prior antigen exposure, and γδ T cells are the major initial IL-17 producers. In fact, some γδ T cells make IL-17 within hours after an immune challenge. These cells appear to acquire the ability to respond to IL-1 and IL-23 and to make IL-17 naturally in naïve animals. They are...
