OBJECTIVES: Giant cell arteritis (GCA) is the most common form of systemic vasculitis. Glucocorticoids are an effective treatment but have significant adverse events and relapses are common. Interleukins 12 (IL-12) and 23 (IL-23) stimulate TH 1 and TH 17 responses and are implicated in the pathogenesis of GCA. The aim of this study was to evaluate the efficacy and safety of IL-12/23 blockade with ustekinumab in GCA. METHODS: We performed a prospective open label study of ustekinumab in patients with refractory GCA...

Previous studies have established that an increased Th-9 response creates a hostile environment for nematode parasites. Given that IL-23, a cytokine required for maintenance of the IL-17-secreting phenotype, has inhibitory effects on IL-9 production, we hypothesized that reducing circulating IL-23 by treatment with anti-IL-23 antibodies would reduce the establishment and development of parasitic intestinal nematodes. In this study, we show that animals treated with anti-IL-23 monoclonal antibodies showed a drastic reduction in the number of mouse pinworms (Aspiculuris tetraptera) recovered from the intestine (p < 0...

Guselkumab is an antibody designed to bind to the p19 subunit of interleukin-23 (IL-23). Detailed studies of affected skin in patients with psoriasis demonstrated that guselkumab induced significant changes in the cellular, cytokine and gene expression profiles of psoriatic lesions accompanied by significant changes in clinical measures of disease activity. The significant clinical response in psoriasis was demonstrated in these studies by significant improvement as reflected in the percentage of patients achieving a Physicians Global Assessment score of 0 or 1, and a 90% or 100% improvement in the Psoriasis Area and Severity Index (PASI 90, PASI 100), as well as changes in quality of life measures...

U Syrbe, X Baraliakos
Spondyloarthritis (SpA) describes the group of inflammatory diseases characterized by inflammation within axial joints and/or peripheral arthritis, enthesitis, and dactylitis. Disease development is strongly determined by genes and particularly associated with the presence of HLA-B27. Transgenic expression in animal models leads to induction of a SpA-like disease, suggesting a direct effect of HLA-B27 on disease development. Genome-wide association studies in SpA patients have identified further associations between polymorphisms in genes with an immune function, in particular in genes controlling the interleukin (IL)-23/IL-17 signaling pathway...

γδ T cells have been implicated in inflammatory diseases as an important link between the innate and adaptive immune responses, however, their role in inflammatory arthritis remain unclear. To define the contribution of γδ T cells in the pathogenesis of inflammatory arthritis, we performed gene transfer of IL-23 in B10.RIII mice to establish joint inflammation in the presence or absence of γδ T cells. We demonstrated that γδ T cell blockade has a protective effect on arthritis incidence and severity by preventing neutrophil accumulation in the blood, spleen and bone marrow as well as by reducing neutrophil infiltration into the joints...

The gut epithelium acts to separate host immune cells from unrestricted interactions with the microbiota and other environmental stimuli. In response to epithelial damage or dysfunction, immune cells are activated to produce interleukin (IL)-22, which is involved in repair and protection of barrier surfaces. However, the specific pathways leading to IL-22 and associated antimicrobial peptide (AMP) production in response to intestinal tissue damage remain incompletely understood. Here, we define a critical IL-36/IL-23/IL-22 cytokine network that is instrumental for AMP production and host defense...

Psoriasis is a chronic skin condition whose pathogenesis is reported to be due to the activation of the interleukin-23/interleukin-17 (IL-23/IL-17) pathway. Here, we report that indoleamine 2,3-dioxygenase (IDO)-expressing fibroblasts reduce the activity of this pathway in activated immune cells. The findings showed that intralesional injection of IDO-expressing fibroblasts in imiquimod-induced psoriasis-like dermatitis on the back and ear (Pso. ear group) in mice significantly improves the clinical lesional appearance by reducing the number of skin-infiltrated IL-17+ CD4+ T cells (1...

Immune imbalance of T lymphocyte subsets is a hallmark of psoriasis, but the molecular mechanisms underlying this aspect of psoriasis pathology are poorly understood. Here, we report that microRNA-210 (miR-210), a miR that is highly expressed in both psoriasis patients and mouse models, induces helper T (Th) 17 and Th1 cell differentiation but inhibits Th2 differentiation through repressing STAT6 and LYN expression, contributing to several aspects of the immune imbalance in psoriasis. Both miR-210 ablation in mice and inhibition of miR-210 by intradermal injection of antagomir-210 blocked the immune imbalance and the development of psoriasis-like inflammation in an imiquimod-induced or IL-23-induced psoriasis-like mouse model...

BACKGROUND AND AIMS: Transplantation is the best treatment option for end stage kidney disease. The most common early complications in post-transplant period are acute rejection (AR) of the graft and delayed graft function (DGF). The underlying mechanisms in these events are heterogeneous and at least in part involve cytokine genes which regulate immune response to allograft. We have investigated whether functional single nucleotide polymorphisms (SNP) in the genes encoding IFN-γ (IFNG), TNF (TNFA), IL-10 (IL10) and p40 subunit of IL-12/IL-23 (IL12B) could predict risk of AR and DGF in kidney allograft recipients...

γδ T-cells perform a wide range of tissue and disease specific functions that are dependent on the effector cytokines produced by these cells. However, the aggregate signals required for the development of interferon-γ (IFNγ) and interleukin-17 (IL-17) producing γδ T-cells remain unknown. Here, we define the cues involved in the functional programming of γδ T-cells, by examining the roles of T-cell receptor (TCR), Notch, and cytokine-receptor signaling. KN6 γδTCR-transduced Rag2-/- T-cell progenitors were cultured on stromal cells variably expressing TCR and Notch ligands, supplemented with different cytokines...

REVIEW

IL-35 is a relatively new cytokine that emerges as an important immunomodulator. IL-35 belongs to IL-12 cytokine family that includes IL-12, IL-23, IL-27, and IL-35. These cytokines are heterodimers that share subunits and their receptors also share subunits. Whereas IL-12 and IL-23 are clearly proinflammatory cytokines, the role of IL-35 is less clear. In mice, IL-35 appears to be anti-inflammatory and to protect from autoimmune inflammatory diseases. IL-35 induces the expansion of a subset of regulatory T cells (Tregs) and Bregs and mediates their suppressive function and inhibits Th17 cells...

Ulcerative colitis (UC) is a chronic, idiopathic, inflammatory bowel disease of the colon. T cell responses have been associated with the pathology of UC. Andrographis paniculata (AP) extract has been previously reported as an effective treatment of UC. The present study aimed to explore the effects of andrographolide, the primary active component of AP, on the T cell responses of patients with UC. Peripheral blood mononuclear cells (PBMCs) were isolated from patients with UC and treated with various concentrations of andrographolide (0, 10, 20 and 30 µg/ml)...

Immune mediated diseases (IMDs) are complex chronic inflammatory diseases involving genetic and environmental factors. Salt intake has been proposed as a diet factor that can influence the immune response. Indeed, experimental data report the influence of sodium chloride on the differentiation of naive CD4+ T cells into IL-17 secreting T helper (Th) cells (Th17 cells), by a mechanism involving the serum glucocorticoid kinase-1 (SGK1) that promotes the expression of the IL-23 receptor (IL-23R). The IL-23/IL-23R is critical for pathogenic inflammatory Th17 cell differentiation...

Psoriasis is a chronic inflammatory cutaneous disease characterized by clinical manifestations of erythema and white scales. The pathogenesis of psoriasis is not yet clear. Despite a combination of hormonal therapy and physiotherapy used in Western medicine, the condition often relapses after withdrawal of drugs. Traditional Chinese medicine (TCM) has therapeutic features and may be a clinically effective formula by regulating unbalanced immune systems, such as by targeting interleukins. In this paper, we review recent research about how Chinese medicine immunoregulates psoriasis via interleukins, and systematically summarizes the related mechanisms...
