This study was aimed to identify key genes and potential prospective drugs for CE pathogenesis. Methods: Clinical microarray dataset - GSE63741 from Gene Expression Omnibus database was chosen to identify differentially expressed genes (DEGs) in CE. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes and Gene set enrichment analysis analyses were conducted to explore the relationships of the DEGs, and a protein-protein interactions network was built using STRING database. Connectivity Map (CMap) analyses were carried out to identify candidate compounds. CE model mice were induced by dinitrochlorobenzene for therapeutic evaluation. The tissue levels of interleukin (IL) -4 and tumor necrosis factor (TNF) -α in mice ears and the serum levels of TNF-α, IL-4, IL-6, and IFN-γ were assessed by immunohistochemistry, respectively. Western blotting was employed to assay the Enolase 2 (ENO2) and Hexokinase Ⅱ (HK2) expression. One-way ANOVA revealed significant differences among groups, followed by Tukey’s post hoc test for pairwise comparisons. Results: A total of 94 DEGs were identified, comprising 48 upregulated genes and 46 downregulated genes. The Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed that the DEGs were primarily influenced by the IL-17, Staphylococcus aureus infection, and estrogen signaling pathway. The protein-protein interactions network consisted of 30 hub genes, 586 edges, and 79 nodes. In the Gene set enrichment analysis analyses, the DEGs were predominantly involved in signaling pathways related to IL-2, IL-6, interferon (IFN)-γ, and IFN-α. The connectivity Map analysis identified 2-deoxy-D-glucose (2-DG) as a potential therapeutic agent for CE. In the therapeutic evaluation, the 2-DG-treated mice exhibited significantly reduced epidermal thickness, inflammatory cell infiltration, and right ear weight compared with the model mice, with dose-dependence. Moreover, 2-DG exerted anti-inflammatory effects by inhibiting the expression of pro-inflammatory cytokines TNF-α, IL-6, IFN-γ (Model vs. 4% 2-DG, TNF-α, 1,208 ± 39.92 ng/L vs. 1,040.44 ± 36.92 ng/L; IL-6, 179.81 pg/mL ± 7.13 vs . 153.44 ± 5.95 pg/mL; IFN-γ, 1,225.58 ± 52.72 ng/L vs. 1,028.29 ± 55.23 ng/L, all P < 0.001,) and increasing the expression levels of IL-4 in both the ear tissue and serum (Model vs. 4% 2-DG, 135.45 ± 12.21 pg/mL vs. 227.42 ± 8.44 pg/mL, P <0.001). 2-DG also reduced the protein expressions of ENO2 (Model vs. 4% 2-DG, 0.99 ± 0.16 vs. 1.55 ± 0.02, P < 0.001) and HK2 (Model vs. 4% 2-DG, 1.97 ± 0.22 vs. 2.37 ± 0.06, P = 0.024) in the ear tissue.

Although its relationship with pathogenesis of psoriasis is unclear, this research aimed to assess the possible role of IL-15 in the pathogenesis of psoriasis and its correlation with the disease severity. Methods: Fifty patients with chronic plaque psoriasis were selected for this case–control study at Alexandria Main University Hospital from December 2022 to January 2024. Clinical evaluation of the patients was achieved through the calculation of the Psoriasis Area and Severity Index score. Serum IL-15 levels were measured by enzyme linked immunosorbent assay. The Mann–Whitney test was employed for abnormally distributed quantitative variables. The Spearman coefficient test was applied for comparisons of two abnormally distributed quantitative variables. Results: The mean serum IL-15 Level in the patient group (482.90 ng/mL [Q1 = 440.63, Q3 = 525.16]) was significantly higher than that in the control group (410.25 ng/mL [Q1 = 310.23, Q3 = 430.35]) ( P < 0.001). Furthermore, the serum IL-15 level had a significant positive correlation with the Psoriasis Area and Severity Index score ( P = 0.049).

However, whether metformin can mitigate contact dermatitis and the underlying mechanisms remain unknown. Therefore, we conducted these in vitro and in vivo experiments to investigate the therapeutic effects of metformin on 2,4-dinitrochlorobenzene (DNCB)–induced contact dermatitis. Methods: The animal model used in the experiment was DNCB-induced contact dermatitis model, and HaCaT cells were used for in vitro experiments. Animal experiments were conducted in randomized groups. Patch tests were conducted to evaluate the irritation caused by different concentrations of metformin on mouse skin, and determined the optimal metformin concentration for following experiments. Propidium iodide staining was used to label dead cells, and western blotting was performed to assess changes in protein levels following metformin treatment. Immunofluorescence experiments were used to compare phosphorylated mixed lineage kinase domain-like protein levels before and after topical metformin administration in a DNCB-induced contact hypersensitivity mouse model. Data from the 2 groups were analyzed using the t test, and for comparisons involving 3 or more groups, a one-way analysis of variance was used. Results: In a DNCB-induced contact hypersensitivity mouse model, topical application of 4.0% metformin significantly alleviated skin inflammation (the dermatitis score reduced from 9.83 ± 0.29 to 5.17 ± 0.76, P < 0.05), and reduced the proportion of dead cells from 46.83% ± 9.25% to 9.77% ± 9.54% ( P < 0.05), and reduced phosphorylation levels of mixed lineage kinase domain-like protein in keratinocytes. In vitro experiments further demonstrated that metformin inhibited necroptosis in HaCaT cells under a contact dermatitis–like environment simulated by tumor necrosis factor-α and interferon-γ. Conclusions: These findings suggest that metformin inhibits keratinocyte necroptosis, thereby alleviating inflammation in contact dermatitis. The topical application of metformin may represent a potential therapeutic approach for contact dermatitis, which needs further in vitro and in vivo experiments for investigation.","PeriodicalId":73440,"journal":{"name":"International journal of dermatology and venereology","volume":"8 3","pages":"125-133"},"PeriodicalIF":0.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147906262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pathogenesis of HS remains unclear, but it is being increasingly recognized to rely on the dysregulation of inflammatory responses. Central to this process are macrophages, which have emerged as key players in the inflammatory milieu of HS. These cells orchestrate inflammation via polarization and significantly influence the functions of neighboring cells. This review briefly describes macrophage polarization and crosstalk between macrophages and other cells in patients with HS with the aim of providing new therapeutic strategies for the clinical management of HS.","PeriodicalId":73440,"journal":{"name":"International journal of dermatology and venereology","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140383997","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}
