Although studies have examined miRNA in pediatric atopic dermatitis (AD), the impact of topical corticosteroid (TCS) therapy on miRNA expression in pediatric AD has not been investigated. We sought to investigate the effects of 6 weeks of TCS therapy on miRNA expression in infants with AD. Small RNA sequencing and real-time RT-qPCR were performed to identify differentially expressed miRNAs in PBMCs of infants with AD after TCS treatment; HTG EdgeSeq was used to identify differentially expressed miRNAs in plasma. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis was conducted using a list of experimentally verified miRNA targets sourced from the DIANA-TarBase and miRTarBase databases. Five miRNAs were differentially expressed in circulating PBMCs after TCS treatment (miR-143-3p, miR-27a-5p, miR-126-3p, miR-451a, and miR-223-3p); 12 miRNAs were differentially expressed in plasma. These miRNAs have regulatory functions crucial for regulating cell growth and survival, vascular adhesion, angiogenesis, skin barrier integrity, stress and nervous system processes, immune responses, inflammation, and T helper 17 cell differentiation. TCS treatment led to a distinct miRNA expression profile in peripheral blood, providing insights into how this treatment impacts disease mechanisms in childhood AD.</div></div>","PeriodicalId":73548,"journal":{"name":"JID innovations : skin science from molecules to population health","volume":"5 5","pages":"Article 100388"},"PeriodicalIF":0.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144535414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We found an association (<em>P</em> < .05) between p16INK4a-positive cells in the epidermis and the BCC genetic risk score but not among those in the dermis, which was driven by SNVs in the <em>MC1R</em> (<em>P</em> < .001) and <em>IRF4</em> (<em>P</em> = .02) genes. Because melanocytes are the dominant p16INK4a-positive cell in sun-protected epidermal skin, these findings suggest that p16INK4a-positive melanocytes could be contributing to BCC risk. However, an indirect association between p16INK4a-positive cells and BCC risk through SNV pleiotropy is alternatively possible, and confirmation of how many p16INK4a epidermal cells are truly senescent is required. Because <em>MC1R</em> and <em>IRF4</em> genetic variants are strongly linked to skin cancer risk, further investigation into a potential role for these p16INK4a-positive cells in skin cancer risk is warranted.</div></div>","PeriodicalId":73548,"journal":{"name":"JID innovations : skin science from molecules to population health","volume":"5 5","pages":"Article 100389"},"PeriodicalIF":0.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144535413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Human N/TERT keratinocytes were engineered to express doxycycline-inducible short hairpin RNAs targeting ceramide synthase 3, which is essential for synthesis of ultralong-chain ceramides and skin barrier function. We show that 3-dimensional human skin equivalents with induced knockdown of ceramide synthase 3 display normal stratification and terminal differentiation but have reduced Nile red staining for polar lipids. Further analysis of the lipidome by mass spectrometry confirmed a significant reduction in specific classes of ceramides and ceramide chain length in the ceramide synthase 3–depleted human skin equivalents. We also show that ceramide synthase 3 knockdown is reversible upon removal of doxycycline and can be used to study recovery and repair of epidermal lipids. Together, these findings provide an overall strategy for genetically regulating the lipid composition within human skin models and establish a tunable in vitro model of ceramide deficiency.</div></div>","PeriodicalId":73548,"journal":{"name":"JID innovations : skin science from molecules to population health","volume":"5 4","pages":"Article 100383"},"PeriodicalIF":0.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144190202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By integrating deep clinical phenotyping and repetitive multiomics analyses of tissue and circulation of patients covering the whole spectrum of chronic skin inflammation independent of the traditional disease nomenclature, the translational dermatology initiative creates a high-quality dataset optimized for machine learning. The aim of the translational dermatology initiative is to reclassify inflammatory skin diseases on the basis of objective molecular events that enable prediction of clinically meaningful outcome variables.

No studies have reported measuring the stiffness change in neurofibromas, which would indicate shrinking of the tumor bulk. The goal of this study was to evaluate 2 different instruments—the Rex Gauge durometer (denoted as REX) and the Delfin SkinFibroMeter (denoted as DELFIN)—in reproducibly measuring cNF stiffness. Ninety-seven neurofibromas from patients with neurofibromatosis type 1 on different skin areas were measured at each of 2 visits about 2 weeks apart.
