Narrowband UVB (NBUVB) phototherapy is an effective treatment for some skin diseases; however, its mechanism of action and its potential for treating diseases away from the skin are not well-understood. Solar-simulated UV modulates immune cells, in part, by altering lipids. However, whether NBUVB has the same effect on these cells and molecules is unknown. Exposure of mice to an immunosuppressive dose of NBUVB did not affect plasma lipid levels, which were altered after solar-simulated UV irradiation. Surprisingly, unlike what occurs after solar-simulated UV irradiation, dermal mast cells and lymphocyte recirculation were unaffected by NBUVB. NBUVB-irradiated skin showed a reduced number of epidermal CD207<sup>+</sup> cells and cutaneous CD3<sup>+</sup> T cells, and was infiltrated by Ly6G<sup>+</sup> neutrophils. There was also an increase in the number of CD4<sup>+</sup>FoxP3<sup>+</sup> T cells in the skin-draining lymph nodes and suppression of antigen-specific CD8<sup>+</sup> T-cell activity in vivo. Thus, immunosuppressive NBUVB activates some but not all the pathways responsible for the immunosuppressive effects of solar-simulated UV. Understanding the wavelength-dependent effects of UVR on the immune system is essential to harness its immunomodulatory capacity to treat a wide range of diseases.</p>","PeriodicalId":94239,"journal":{"name":"The Journal of investigative dermatology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143257686","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}

Pemphigus vulgaris (PV) is an autoimmune epidermal blistering disease caused by autoantibodies (IgG) targeting desmoglein 3, a desmosomal cadherin. PV autoantibodies cause desmosome disassembly and loss of cell-cell adhesion; however, the molecular signaling pathways that regulate these processes are not fully understood. Using high-resolution time-lapse imaging of live keratinocytes, we found that endoplasmic reticulum (ER) tubules make frequent and persistent contacts with internalizing desmoglein 3 puncta in keratinocytes treated with IgG of patients with PV. Biochemical experiments demonstrated that PV IgG activated ER stress signaling pathways, including both IRE1⍺ and PERK pathways, in cultured keratinocytes. Furthermore, ER stress transcripts were upregulated in the skin of patients with PV. Pharmacological inhibition of ER stress protects against PV IgG-induced desmosome disruption and loss of keratinocyte cell-cell adhesion, suggesting that ER stress may be an important pathomechanism and a therapeutically targetable pathway for PV treatment. These data support a model in which desmosome adhesion is integrated with ER function to serve as a cell adhesion stress sensor that is activated in blistering skin diseases.</p>","PeriodicalId":94239,"journal":{"name":"The Journal of investigative dermatology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143257690","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 propose AgenTopic, an interactive topic modeling framework that integrates Bidirectional Encoder Representations from Transformers embeddings, dimensionality reduction, clustering, and a language model feedback loop to analyze the psoriasis research literature from 2000 to 2023. Applied to PubMed articles, AgenTopic extracted 158 psoriasis-related topics across 8 categories, outperforming traditional methods in handling complex medical literature. Further trend analysis using multiple modeling techniques, including a support vector regression-Linear model, revealed nonlinear patterns in research growth across categories (R<sup>2</sup> values = 0.75-0.97). Key trends identified include focus on nail psoriasis and spondyloarthritis, shift from TNF-α to IL-17 in pathogenesis understanding, rapid development of biologics and small-molecule inhibitors, and increased attention to comorbidities. We developed an interactive web tool to facilitate literature retrieval and identification of trends. To the best of our knowledge, this application of an agent-based interactive topic modeling framework to dermatological literature has not been previously reported. Using only topic-modeled data, our framework achieved a performance comparable with that of expert manual reviews in identifying research trends. AgenTopic performed better than several state-of-the-art topic modeling methods and demonstrated the potential of artificial intelligence for advancing medical literature analyses.</p>","PeriodicalId":94239,"journal":{"name":"The Journal of investigative dermatology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143082800","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}

Itching, induced by irritants or allergens that stimulate pruriceptive neurons, triggers uncontrollable mechanical scratching, leading to epidermal barrier disruption, immune response activation, inflammatory mediator release, and further stimulation of pruritus conduction. Although oxidative stress and immune cells can exacerbate this cycle, the correlation between mechanical scratching, epidermal oxidative stress, and dermal mast cell activation in AD remains unclear. Here, by examining clinical specimens of AD, establishing a three-dimensional co-culture system of HaCaT and LAD2 cells, and utilizing a mechanical scratching mouse model of AD, we found that reactive oxygen species produced by mechanically stimulated HaCaT can activate TRPA1 on mast cells presenting tryptase (TPS). Implementing a free radical scavenger and TRPA1 inhibitor can inhibit mast cell activation and type II inflammatory response, thereby alleviating itching and skin lesions in AD. These results indicate that active oxygen scavenging combined with TRPA1 inhibition can inhibit the itch-scratch cycle, which may present a potential approach for the treatment of AD.</p>","PeriodicalId":94239,"journal":{"name":"The Journal of investigative dermatology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143076763","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}
