We performed the diacron-reactive oxygen metabolite (d-ROM) test and the biological antioxidant potential (BAP) test on sera from nine patients with active GPP who were hospitalised and treated at our hospital, including three patients with pustular psoriasis of pregnancy (PPP). The serum d-ROM and BAP levels were evaluated before treatment and at 1 month of treatment. We also performed immunostaining of 4-hydroxy-2-nonenal (4-HNE) in skin tissues. In the GPP patients, the average d-ROM levels were significantly reduced at 1 month of treatment (reduced to 343.0 ± 82.1 U.Carr from 423.2 ± 95.0 U.Carr, p = 0.005). The Generalised Pustular Psoriasis Area and Severity Index (GPPASI) score correlated with d-ROM levels (r = 0.57, p = 0.10), suggesting that those levels reflect the disease severity. In normal pregnancy, d-ROM values are known to increase from mid-term to late-term. The d-ROM values increased when GPP worsened in the case of PPP. Immunohistochemical staining of 4-HNE was positive for subcorneal pustules, neutrophils, and for the cytoplasm of epidermal keratinocytes, especially in upper epidermal layers. Our findings indicate that 4-HNE may play an important role in GPP and PPP.","PeriodicalId":12243,"journal":{"name":"Experimental Dermatology","volume":"34 3","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/exd.70076","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143581669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the air pollutants, UV radiation and particulate matter (PM) have been found among the most aggressive in terms of skin damage, inducing oxinflammatory responses, promoting degradation of extracellular matrix (ECM) components, and compromising the cutaneous defensive barrier. Topical application of technologies able to prevent oxidative damage is still one of the best approaches to protect our skin, and considering the well-known antioxidant network, application of an antioxidant mixture is more recommended than a single compound. In the present study, human skin explants were exposed every day for 4 days to diesel particles (DEE) or to UV after the daily pre-treatment with a topical application of a commercially available antioxidant mixture (AOX Mix), containing 15% ascorbic acid, 0.5% ferulic acid and 1% tocopherol. Oxidative stress markers such as 4-hydroxynonenal, skin barrier proteins such as involucrin, filaggrin, claudin-1 and desmocollin-1, resilience markers such as elastin and tropoelastin, and the levels of Type I and Type III collagens were assessed. Topical application was able to prevent most of the damage induced by the outdoor stressors, confirming that daily protection is needed to prevent cutaneous premature ageing.","PeriodicalId":12243,"journal":{"name":"Experimental Dermatology","volume":"34 3","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/exd.70069","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143581671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several cases with nonsense ATP2A2 mutations presented mild-to-moderate phenotypes despite the presumed larger deletion sizes of the ATP2A2 protein. Here, we report a case of severe DD caused by a nonsense mutation with a mitochondrial DNA (mtDNA) insertion despite the smaller presumed deletion size of the ATP2A2 protein. In silico analyses of genomic lesions forming non-B DNA structures and sequence homology indicated the contingency of this DNA insertion. Analysis of the three-dimensional structure of the protein predicted no structural disturbance by this insertion. However, the QGRS Mapper algorithm predicted ectopic G-quadruplex formation in the inserted genome, which may possibly reduce ATP2A2 transcription. Consistent with this hypothetical mechanism and possible nonsense-mediated mRNA decay, we identified downregulation of the mtDNA-inserted ATP2A2, which may partially contribute to the severe phenotype in this case. The mtDNA insertions into the human genome are reported to rarely occur, especially in cancers, and only a handful of mtDNA insertions causing genetic diseases are described. This study is the first report to identify mtDNA insertion as a cause of genetic disease in dermatology and demonstrates its pathophysiological mechanism through in silico analyses.","PeriodicalId":12243,"journal":{"name":"Experimental Dermatology","volume":"34 3","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/exd.70070","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143581581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have developed a functional, pigmented, human full-thickness 3D skin equivalent to determine whether the presence of melanocytes impacts epidermal bacterial growth and regulates the expression of genes involved in the immune response. We introduced primary epidermal melanocytes to construct a 3-cell full-thickness skin equivalent with primary dermal fibroblasts and epidermal keratinocytes. Immunohistochemistry verified the appropriate ratio and spatial organisation of melanocytes. Alpha-MSH induced melanogenesis, confirming an appropriate physiological response. We compared this 3-cell skin equivalent with the 2-cell version without melanocytes in response to inoculation with 3 species of bacteria: Staphylococcus epidermidis, Corynebacterium striatum, and Cutibacterium acnes. There was a significant decrease in the colonisation of bacteria in the skin equivalents containing functional melanocytes. There was increased expression of immune-response genes (S100A9, DEFB4A, IL-4R) following microorganism exposure; however, there were marked differences between the unpigmented and pigmented skin equivalents. This physiologically relevant human 3D-skin equivalent opens up new avenues for studying complex skin pigmentation disorders, melanoma, and UV damage, as well as the rapidly evolving field of the skin microbiome and the balance between commensal and pathogenic species.","PeriodicalId":12243,"journal":{"name":"Experimental Dermatology","volume":"34 3","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/exd.70071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143565049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the role of the ECM, namely, to maintain homeostasis and steer adaptive immunity, is well described in secondary lymphoid organs, it is underappreciated in the skin—despite remarkable molecular similarity. Here, we examine how the specialised organisation of the ECM influences B cell development and function in both skin and secondary lymphoid organs with a special focus on ECM–integrin signalling. We discuss the presence and function of B cells in healthy and diseased skin, including their role in wound healing, autoimmune responses and inflammatory conditions. Additionally, we explore the formation of tertiary lymphoid structures in chronic skin diseases as a window into studying B cell–ECM interactions. By integrating fundamental immunology with skin biology, we aim to identify key knowledge gaps and explore potential clinical implications of B cell–ECM interactions in dermatology and beyond.","PeriodicalId":12243,"journal":{"name":"Experimental Dermatology","volume":"34 3","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/exd.70068","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143565048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To explore the link between periostin levels and key clinical parameters in BP, serum periostin levels were assessed in 55 classic BP patients and 55 healthy controls using ELISA. Upon admission, the BP Disease Area Index (BPDAI) score, autoantibody levels, and peripheral blood immune cells of BP patients were evaluated. The investigation also employed the Olink proteomic platform to analyse circulating proinflammatory biomarkers. The results indicated significantly higher periostin levels in BP patients, showing a strong positive correlation with BPDAI scores, which was more pronounced compared to the correlation between BPDAI scores and BP 180 IgG or eosinophil counts. Correlation analysis revealed positive links between periostin levels in serum and attributes such as urticaria/erythema lesions, total IgE levels, serum BP180 IgG, BP180 IgE, BP230 IgE, and blood eosinophil counts. The findings from the Olink proteomic analysis provided additional evidence of the connection between periostin and type II inflammation in BP, which was further validated by the observed positive correlation between periostin and IL-13 using ELISA. Furthermore, it was observed that serum periostin levels decreased post-effective treatment.

Some of the crucial steps and pathways in healing mechanisms are the hypoxic response and the expression of host defence peptides, which are decreased in diseases related to chronic wounds such as diabetes mellitus and cardiovascular diseases. It has been shown that histone deacetylase inhibitors can induce the expression of Host Defence Peptides (HDP) by inducing the stabilisation and activation of hypoxia-inducible factor 1-α (HIF-1α), promoting wound healing pathways, although their high cost and side effects limit clinical research. With the help of bioinformatics tools, we found potential histone deacetylase inhibitor candidates in an FDA-approved drugs database. The candidates, 1,3-Diphenylurea (DiPU), 2'-Aminoacetanilide (Ace), and Tert-butyl (2-aminophenyl) carbamate (N-boc), show wound healing effects in HaCaT cells, increasing cell migration possibly via HIF-1α, inducing the expression of LL-37 and vascular endothelial growth factor (VEGF), while in a mouse ring angiogenesis model, Ace and N-boc have angiogenic effects. In a model of basal primary keratinocytes from donors with diabetes mellitus (DM), without DM, and from Diabetic Foot Ulcers (DFU), it was observed that only DiPU is capable of inducing LL-37 in all scenarios. There is limited information about histone deacetylase inhibitors and wound healing but in this paper, we observe promising results and a proposed mechanism that involved specifically Histone Deacetylase 1 inhibition (HDAC1).\u0000 </div>","PeriodicalId":12243,"journal":{"name":"Experimental Dermatology","volume":"34 2","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current therapies targeting skin tumour subtypes, such as basal cell carcinoma, cutaneous squamous cell carcinoma, melanoma and actinic keratosis, vary in their degree of effectiveness and tolerability, motivating new research avenues on complementing treatment strategies. Cold medical gas plasma is a partially ionised gas operated at about body temperature and generates various reactive oxygen and nitrogen species simultaneously. A range of medical gas plasma devices has proven safe in thousands of patients and is an approved medical product for dermatology conditions, such as nonhealing wounds, in Europe and, more broadly, for clinical trials. Extending potential gas plasma applications in the field of dermato-oncology is therefore plausible, especially in light of the strong preclinical evidence and early clinical data. This review summarises existing work on gas plasma treatment, focusing on approved jet plasmas in skin cancer and outlining central mechanisms and treatment concepts.
