RORγt -expressing FOXP3+ skin-resident Treg cells derived from the periphery in Allergen-Specific Immunotherapy

ABSTRACT: The study explored the impact of Specific Immunotherapy on patients with Atopic Dermatitis sensitized to house dust mites by analyzing the transcriptomes of T regulatory cells before and after treatment. Result found that effective SIT is associated with distinct gene expression changes in Treg cells, particularly increased expression of Treg markers and RORC, a gene linked to immune regulation. These results indicate that successful SIT may enhance the function of Treg cells expressed RORC and help restore immune balance in these patients.

EGR1 increases the innervation density of epidermal sensory neurons via upregulation of ARTN in keratinocytes in atopic dermatitis

Project description:Atopic dermatitis (AD) is the chronic inflammatory skin disease accompanied with severe pruritus. To explore the roles of EGR1 in atopic dermatitis and the relationship between EGR1 and pruritus-scratching behavior, we used a atopic dermatitis-like mouse model driven by house dust mite (HDM) treatment in wild type and EGR1 KO mice, followed with RNA-sequencing analysis.

Sonic Hedgehog signalling to T cells limits induction of chronic murine atopic dermatitis via Gli2-driven immune regulatory function

Project description:Hedgehog (Hh) proteins are morphogens which regulate embryonic development and adult tissue homeostasis, with distinct outcomes dependent on the strength and duration of their signals. We show that the Hh signalling pathway modulates the induction and pathology of mouse atopic dermatitis. Sonic hedgehog (Shh) and Hh pathway target genes were upregulated on induction of atopic dermatitis, and the Hh pathway was activated in skin T cells, showing that they respond in vivo to Hh signals secreted from the skin. Shh upregulation reduced skin inflammation in mice, whereas pharmacological Smoothened-inhibition reduced Shh upregulation and exacerbated skin pathology. Hh-signalling to T cells prevented skin inflammation on induction of dermatitis, while inhibition of Hh-mediated transcription in T cells substantially exacerbated the disease. RNA-sequencing analysis of skin CD4+ T cells from mice with chronic atopic dermatitis revealed decreased expression of immune regulatory genes in mice with conditional inhibition of Hh-mediated transcription in T cells, and increased expression of inflammatory and chemokine genes. In contrast, constitutive Hh mediated transcription in T cells led to increased expression of immune regulatory genes in skin CD4+ T cells from mice with chronic atopic dermatitis and protected against inflammation. Hh-mediated transcription in T cells resulted in increased regulatory T (Treg) cells in the periphery and skin of dermatitis-induced mice, and increased TGF-β expression, supporting their immunoregulatory phenotype, whereas, inhibition of T cell specific Hh-mediated transcription, resulted in impaired Treg function, which permitted progression of skin inflammation.

Genomic profiling of the overlap phenotype between psoriasis and atopic dermatitis

Project description:Clinical overlaps between psoriasis and atopic dermatitis are sometimes undiscernible, and there is no consensus whether to treat the overlap phenotype as psoriasis or atopic dermatitis. We enrolled patients diagnosed with either psoriasis or atopic dermatitis, and clinically re-stratified them into classic psoriasis, classic atopic dermatitis, and the overlap phenotype between psoriasis and atopic dermatitis. We compared gene expression profiles of lesional and nonlesional skin biopsy tissues between the three comparison groups. Global mRNA expression and T-cell subset cytokine expression in the skin of the overlap phenotype were consistent with the profiles of psoriasis and different from the profiles of atopic dermatitis. Unsupervised k-means clustering indicated that the best number of distinct clusters for the total population of the three comparison groups was two, and the two clusters of psoriasis and atopic dermatitis were differentiated by gene expression. Our study suggests that clinical overlap phenotype between psoriasis and atopic dermatitis has dominant molecular features of psoriasis, and genomic biomarkers can differentiate psoriasis and atopic dermatitis at molecular levels in patients with a spectrum of psoriasis and atopic dermatitis.

The transcriptomic profile of peripheral blood nuclear cells in dogs with atopic dermatitis before and after 6 months allergen-specific immunotherapy.

Project description:The aim of the study was to identify genes which are differentially expressed in the blood of dogs with canine atopic dermatitis (AD) before and after 6 months of allergen-specific immunotherapy (ASIT) in comparison to healthy control dogs. Diagnosis of AD was based on compatible history and clinical signs determined using Willemse and Prélaud diagnostic criteria, completed by Favrot criteria as follows: pruritus sine material, indoor lifestyle and the exclusion of other causes of pruritus ongoing for at least one year. Clinical diagnosis of atopic dermatitis was confirmed by serological allergy testing (IDEXX allergic panel test) and intradermal skin testing (Artuvetrin test set, Netherlands). In order to avoid the role of food antigens as a cause of the skin condition elimination diet was used for 6–8 weeks. No anti-inflammatory drugs were given for at least 3 weeks prior examination with serological test, intradermal test and blood collection. All dogs, which were classified to the investigated group had positive reactions in serological allergy testing and intradermal skin testing. Subsequently, subcutaneous allergen-specific immunotherapy was applied. Allergen extracts were prepared on the basis of the results of intradermal tests by the Artuvetrin company and were administered subcutaneously in increasing concentrations during 6 months according to the manufacturer's recommendations. Aside from gene regulation, this experiment also examined the participation of individual lymphocyte subpopulations (like: B, T, Th, Tc, Treg) and the level of interleukins in the blood of AD dogs before and after therapy.

Differential gene expression in the skin of dogs sensitized to the house dust mite Dermatophagoides farinae

Project description:Atopic dermatitis is a multifactorial allergic skin disease in humans and dogs. Genetic predisposition, immunologic hyperreactivity, a defective skin barrier and environmental factors play a role in its pathogenesis. The aim of this study was to analyze gene expression in the skin of dogs sensitized to house dust mite antigens. Skin biopsies were collected from six sensitized and six non-sensitized Beagle dogs from normal, non-treated skin before and six and 24 hours after challenge using skin patches with allergen or saline as a negative control. Transcriptome analysis was performed by the use of DNA microarrays and expression of selected genes was validated by quantitative real-time RT-PCR. Expression data was compared between groups (unpaired design). After 24 hours 597 differentially expressed genes were detected, 361 with higher and 226 with lower mRNA concentration in allergen treated skin of sensitized dogs compared to their saline-treated skin and compared to the control specimens. Functional annotation clustering, pathway-and co-citation analysis showed, that the genes with increased expression were involved in inflammation, wound healing and immune response. In contrast, genes with decreased expression in sensitized dogs were associated with differentiation and barrier function of the skin. As the sensitized dogs did not show differences in the untreated skin compared to controls, inflammation after allergen patch test probably led to a decrease in the expression of genes important for barrier formation. Our results further confirm the similar pathophysiology of human and canine atopic dermatitis and revealed genes previously not known to be involved in canine atopic dermatitis. 60 canine (dog) skin tissue samples; six sensitized and six non-sensitized Beagle dogs; samples collected before (0h), 6h and 24h after challenge with allergen; samples collected from a skin area treated with saline and from an area treated with allergen
