Patients with Congenital Ichthyosis and TGM1 Mutations Overexpress Other ARCI Genes in the Skin: Part of a Barrier Repair Response?

Project description:Autosomal recessive congenital ichthyosis (ARCI) is a heterogeneous group of monogenic skin disorders caused by mutations in any of >10 different genes, many of which are involved in epidermal synthesis of ω-O-acylceramides (acylCer), an essential precursor of the corneocyte lipid envelope that is also dependent on transglutaminase-1 for normal skin barrier formation. We hypothesized that inactivating TGM1 mutations, the most common cause of ARCI, might lead to a compensatory overexpression of transcripts involved in barrier repair, including ARCI-causing genes. Using microarray we examined the global mRNA expression profile in skin biopsies from five ARCI-patients with TGM1 mutations and four healthy controls. There were a total of 602 differentially expressed genes (adjusted P<0.05). Gene ontology analysis showed enrichment of mRNA encoding proteins associated with biological pathways mainly involved in keratinocyte differentiation and adaptive/innate immune response. Moreover, among non-syndromic ARCI-causing genes, seven out of twelve were significantly increased (log2fold -change=0.98-2.05). Four genes causing syndromic ichthyosis and seven other genes involved in biosynthesis of fatty acyl-CoA and ceramides were also significantly affected. This study reveals upregulation of several ichthyosis-causing genes in the skin of patients with TGM1 mutations, indicating a compensatory induction of acylCer biosynthesis as a part of a barrier repair mechanism.

The Skin Microbiome of Mycosis fungoides

Project description:The skin Microbiome stratifies Patients with CTCL into two subgroups. One subgroup has a balanced microbiome, while the other subgroups has a skin dybiosis with S. aureus outgrow. This is accompanied by impaired TCR repertoir and poor clinical outcome.

Ichthyosis molecular fingerprinting shows profound Th17-skewing and a unique barrier genomic signature

Project description:The purpose of this study was to analyze the genomic signatures and profiles of skin from ichthyosis (various subtypes) vs. healthy patients. The analysis strategy was to study differentially expressed genes common to the ichthyosis shared phenotype, as well as individual ichthyosis subtypes, and compare and contrast to the genomic profiles of atopic dermatitis and psoriasis.

Modulatory role of skin microbiome against UV

Project description:The role of the skin microbiome in UV-induced immune suppression has been overlooked. We addressed the question of microbial involvement in UV-induced immune suppression by using the standard model of contact hypersensitivity in the presence or absence of the microbiome (in germ-free [GF] and disinfected mice) and found that the microbiome inhibits UV-induced immune suppression. Furthermore, our transcriptome analysis (24 hours after irradiation) showed differential regulation of many genes in the presence or absence of the microbiome, including a predominance of pro-inflammatory cytokines versus immunosuppressive cytokines

Transcriptional profiling unravels enhanced xenobiotic metabolism in the skin of patients with atopic dermatitis but not with ichthyosis vulgaris

Project description:Previous transcriptome analyses confirmed the major role of immunological and skin barrier abnormalities in atopic dermatitis (AD). We here aimed at identifying novel pathogenic pathways involved in AD by comparing AD patients stratified for filaggrin (FLG) mutations not only to healthy donors but also to patients with ichthyosis vulgaris (IV). We applied single-molecule direct RNA-sequencing to analyze the whole transcriptome of nonlesional skin. Six hundred and one genes (478 up-regulated and 123 down-regulated by greater than 2-fold) were differentially expressed when all AD patients were compared to healthy donors. Expression of genes involved in RNA/protein synthesis, RNA splicing, and ATP synthesis was enhanced. Interestingly, genes involved in cell death, response to oxidative stress, DNA damage/repair and xenobiotic metabolism were largely enriched. Two hundred and thirty-seven genes (216 up-regulated and 21 down-regulated by greater than 2-fold) were altered in the skin of IV patients when compared to healthy donors. Remarkably, enhancement of xenobiotic metabolism was only detected in AD skin. Moreover, increased expression of genes encoding for keratinocyte cross-linking (SPRR2) and S100 proteins characterizes the skin of patients with AD flare when compared to patients without. We did not find significant differences in gene profiling between AD patients with and without FLG mutations.This work reveals new putative pathogenic pathways related to xenobiotic metabolisms involved in AD.

Facial Skin Biophysical Multi-Parameter and Microbiome-Based Korean Skin Cutoype (KSC) Determination

Project description:In this study, we conducted an integrated analysis of skin measurements, clinical BSTI surveys, and the skin microbiome of 950 Korean subjects to examine the ideal skin microbiome-biophysical association. By utilizing four skin biophysical parameters, we identified four distinct Korean Skin Cutotypes (KSCs) and categorized the subjects into three aging groups based on their age distribution. We established strong connections between 15 core genera and the four KSC types within the three aging groups, revealing three prominent clusters of the facial skin microbiome. Together with skin microbiome variations, skin tone/elasticity distinguishes aging groups while oiliness/hydration distinguishes individual differences within aging groups. Our study provides prospective reality data for customized skin care based on the microbiome environment of each skin type.
