NF-kB Perturbation Reveals Unique Immunomodulatory Functions in Prx1+ Fibroblasts that Promote Atopic Dermatitis

Project description:Skin is composed of diverse cell populations that cooperatively maintain homeostasis. Upregulation of the NF-kB pathway may lead to the development of chronic inflammatory disorders of the skin, but the early events in situ are not well understood. Through analysis of single cell RNA sequencing (scRNA-seq) data via iterative Random Forest Leave One Out Prediction (iRF-LOOP), an explainable artificial intelligence (X-AI) method, we identified an immunoregulatory role for a unique Prx1+ fibroblast subpopulation. Disruption of Ikkb/NFkB under homeostatic conditions in these fibroblasts paradoxically induced skin inflammation due to the over-expression of CCL11 (eotaxin-1) characterized by eosinophil infiltration and a subsequent Th2 immune response. Because the inflammatory phenotype resembled that seen in human atopic dermatitis (AD), we examined validated human AD skin samples and found that human AD fibroblasts also over-expressed CCL11 compared to control skin. Importantly, we demonstrate that monoclonal antibody treatment against CCL11 was therapeutically effective in reducing the eosinophilia and Th2 inflammation in vivo. Taken together, the murine model and human AD specimens point to dysregulated Prx1+ fibroblasts as a previously unrecognized etiologic factor that may contribute to the pathogenesis of AD-like lesions and suggest targeting CCL11 as a novel way to treat AD-like lesions.

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.

Microarray transcriptome profiling of atopic dermatitis and psoriasis patients compared to healthy volunteers.

Project description:Characteization host-microbiome interactions in patients with allergic (model: atopic dermatitis) and autoimmune (model: psoriasis) diseases by integration of microarray transcriptome data with 16S microbial profiling. 6mm punch biopsies were collected from the skin of atopic dermatitis and psoriasis patients alongside healthy volunteers, and subjected to analysis using Affymetrix Human Gene ST 2.1 arrays.

AhR links air pollution and atopic dermatitis via Artemin induction

Project description:Atopic dermatitis is increasing worldwide, correlating with air pollutions. Various organic components of pollutants activate transcription factor AhR (aryl-hydrocarbon receptor). We have established AhR-CA mice, whose keratinocytes express constitutive-active AhR, and these mice developed atopic dermatitis-like frequent scratching and allergic inflammation. In this study we performed ChIP-seq analyses and identified keratinocyte-specific AhR target genes, including inflammatory cytokines Tslp and IL33, and neurotrophic factor Artemin. While AhR-CA mice exhibited epidermal hyperinnervation and alloknesis leading to hypersensitivity to pruritus, blockade of Artemin alleviated these phenotypes. AhR-CA mice showed scratching-induced barrier insufficiency and enhanced sensitization to epicutaneously-applied antigens, recapitulating human atopic dermatitis. Consistently, AhR activation and Artemin expression was detected in the epidermis of atopic dermatitis patients and keratinocytes exposed to air pollutants. Thus, AhR in keratinocytes senses the environmental stimuli and responds to them through moderating inflammation. We propose a mechanism in which air pollution induces atopic dermatitis through AhR activation.

Profiling of serum microRNAs in children with atopic dermatitis

Project description:Atopic dermatitis (AD) is the most prevalent chronic inflammatory skin disease in children characterized by dermatitis and pruritus. MicroRNAs (miRNAs) have been shown as great potential biomarkers for disease fingerprints to predict prognostics. We aimed to identify miRNA signature from serum and urine for the prognosis of AD patient by genome-wide miRNA profiling analysis. Serum from 8 children with AD and 8 healthy children were collected
