BACKGROUND: Pollutant particles containing environmentally persistent free radicals (EPFRs) are formed during many combustion processes (e.g. thermal remediation of hazardous wastes, diesel/gasoline combustion, wood smoke, cigarette smoke, etc.). Our previous studies demonstrated that acute exposure to EPFRs results in dendritic cell maturation and Th17-biased pulmonary immune responses. Further, in a mouse model of asthma, these responses were enhanced suggesting exposure to EPFRs as a risk factor for the development and/or exacerbation of asthma...

IL-31, which is a member of the IL-6 family of cytokines, is produced mainly by activated CD4+ T cells, in particular activated Th2 cells, suggesting a contribution to development of type-2 immune responses. IL-31 was reported to be increased in specimens from patients with atopic dermatitis, and IL-31-transgenic mice develop atopic dermatitis-like skin inflammation, which is involved in the pathogenesis of atopic dermatitis. However, the role of IL-31 in development of contact dermatitis/contact hypersensitivity (CHS), which is mediated by hapten-specific T cells, including Th2 cells, is not fully understood...

Pro-inflammatory cytokines in the tumor microenvironment are known for their ability to either inhibit or promote cancer progression. Here we evaluated the role of Interleukin-31 (IL31), a protein belonging to the pro-inflammatory IL-6 cytokine family which has been characterized in autoimmune disease, in tumorigenesis. We show that IL31 and its receptor, IL31RA, are highly expressed in various human and mouse cancer cell lines, as well as in tumor specimens from cancer patients. MC38 murine colon carcinoma cells depleted of IL31 exhibit an increase in invasive and migratory properties in vitro, effects that are reversed by supplementing the cells with exogenous IL31...

Mutations of DOCK8 in humans cause a combined immunodeficiency characterized by atopic dermatitis with high serum IgE levels. However, the molecular link between DOCK8 deficiency and atopic skin inflammation is unknown. Here we show that CD4(+) T cells from DOCK8-deficient mice produce large amounts of IL-31, a major pruritogen associated with atopic dermatitis. IL-31 induction critically depends on the transcription factor EPAS1, and its conditional deletion in CD4(+) T cells abrogates skin disease development in DOCK8-deficient mice...

REVIEW
A Heratizadeh, T Werfel
The pathogenesis of atopic dermatitis (AD) is multifactorial and complex. Consequently, clinical signs and symptoms vary strongly depending on individually relevant trigger factors and the stage of the disease. So far, treatment of AD was commonly limited to topical treatment or, in more severe cases, to systemic drugs mostly approved for other indications than AD. However, emerging data on new anti-inflammatory agents have been published in the recent years. As these new substances specifically focus on immune responses in AD, these are partially considered as possible 'breakthrough' in the treatment of AD...

Interleukin-31 (IL-31) is a type 2 helper T-cell-derived cytokine that has recently been shown to cause severe inflammation and tissue remodeling in multiple chronic diseases of the skin and lungs. IL-31 is upregulated in allergic and inflammatory diseases, including atopic dermatitis, asthma, cutaneous T-cell lymphomas, and allergic rhinitis, as well as autoimmune diseases such as systemic erythematosus. Overexpression of IL-31 in T cells causes severe inflammation, with histological features similar to skin lesions of patients with atopic dermatitis...

Determining inflammation and itch pathway activation in patients with atopic dermatitis (AD) is fraught with the inability to precisely assess the age of skin lesions, thus affecting the analysis of time-dependent mediators. To characterize inflammatory events occurring during early experimental acute AD lesions, biopsy samples were collected 6, 24, and 48 hours after epicutaneous application of Dermatophagoides farinae house dust mites to sensitized atopic dogs. The skin transcriptome was assessed using a dog-specific microarray and quantitative PCR...

BACKGROUND: Pruritus is a cardinal symptom of atopic dermatitis, and an increased cutaneous sensory network is thought to contribute to pruritus. Although the immune cell-IL-31-neuron axis has been implicated in severe pruritus during atopic skin inflammation, IL-31's neuropoietic potential remains elusive. OBJECTIVE: We sought to analyze the IL-31-related transcriptome in sensory neurons and to investigate whether IL-31 promotes sensory nerve fiber outgrowth. METHODS: In vitro primary sensory neuron culture systems were subjected to whole-transcriptome sequencing, ingenuity pathway analysis, immunofluorescence, and nerve elongation, as well as branching assays after IL-31 stimulation...

IL-31, a member of the IL-6 protein family, is one of the latest additions to the list of T cell-derived cytokines. Th2 cells are regarded as a main source of IL-31, which is produced in response to stimulation by IL-4. Because the development of Th9 cells also requires IL-4 as a polarizing cytokine, the current study investigates IL-31 production in human Th9 cells compared with Th2 cells. We found that, although Th9 cells were able to release IL-31 during the first weeks of in vitro polarization, no IL-31 was detected in Th9 cultures after a final restimulation in the absence of polarizing cytokines...

BACKGROUND: Most tumors are the result of accumulated genomic alterations in somatic cells. The emerging spectrum of alterations in tumors is complex and the identification of relevant genes and pathways remains a challenge. Furthermore, key cancer genes are usually found amplified or deleted in chromosomal regions containing many other genes. Point mutations, on the other hand, provide exquisite information about amino acid changes that could be implicated in the oncogenic process. Current large-scale genomic projects provide high throughput genomic data in a large number of well-characterized tumor samples...

The aim of this study was to investigate the differential gene expression of cytokines in peripheral blood mononuclear cells (PBMCs) from patients with pulmonary embolism (PE) and controls. Twenty patients with PE and twenty control patients matched for gender and age with the PE group were recruited into the study. Human cDNA microarray analysis was used to detect differences in the expression of cytokine-associated genes between the two groups. In PE patients, the expression levels of the genes encoding IFNα5, IFNα6, IFNα8, IFNα14, IFNκ, IFNω1, IFNε1 and IFNγ were significantly lower compared with controls (P<0...

Few studies have investigated the changes of Th1- and Th2-type cytokines in pulmonary embolism (PE) patients. In this study, the gene expression of interleukins and the balance of Th1- and Th2-type cytokines in the peripheral blood mononuclear cells (PBMCs) of PE patients and controls were investigated. A total of 20 PE patients and 20 gender- and age-matched controls were included in the study. Human cDNA microarray analysis was used to detect the differences in cytokine gene expression between the two groups and a random variance model corrected t-test was used to analyze the statistical data...

IL-31, a newly identified member of the IL-6 cytokine family, is involved in many pathological conditions, including atopic dermatitis and pruritis. In this study, we investigated how expression of IL-31 is regulated in T cells and mast cells. We observed that expression of IL-31 required a calcium signal and was dependent on the calcineurin-NFAT signaling pathway. Moreover, we found that IL-31 promoter contains a positive regulatory region that mediates calcium- and IL-4-dependent induction of the IL-31 gene and demonstrated that a change into an open chromatin conformation occurs in this region after stimulation with calcium and IL-4...

The cytokine repertoire of marsupials is largely unknown. The sequencing of the opossum genome has expedited the identification of many immune genes. However, many genes have not been identified using automated annotation pipelines because of high levels of sequence divergence. To fill gaps in our knowledge of the cytokine gene complement in marsupials, we searched the genome assembly of the gray short-tailed opossum for chemokine, interleukin, colony-stimulating factor, tumor necrosis factor, and transforming growth factor genes...
