Basic information and serum samples were collected from the patients, and flow cytometry was used. T lymphocyte subgroups, CD3⁺CD4⁺and CD3⁺CD8⁺, and natural killer (NK) cells were measured. Patients were divided into infection group and control group according to whether nosocomial infection occurred within 48 h of admission. Age, gender, type of disease, APACHE II score, Charlton score, T lymphocyte subtypes, and NK cell values were compared, and a logistic multivariate regression analysis was conducted. A multifactor regression analysis was performed on various risk factors. The nomogram website was used to draw a nomogram model of meaningful indicators, and the receiver-operating characteristic (ROC) curve was based on experimental results. <b>Results:</b> Logistics multivariate regression analysis showed the Charlton score and NK cell count were independent risk factors for nosocomial infection. Cell counts for subsets CD3⁺CD4⁺ and CD3⁺CD8⁺ were protective factors, and the OR value and 95% CI were 5.199 (1.933-13.983), 1.248 (1.055-1.475), 0.851 (0.790-0.916), and 0.832 (0.711-0.973), <i>p</i> < 0.05. respectively. Statistical significance was set at <i>p</i> < 0.05.The nomogram model suggested that the area under the curve for predicting the risk of nosocomial infection was 0.920 (0.872-0.967), <i>p</i> < 0.001. <b>Conclusion:</b> Patients with low CD3⁺CD4⁺ and CD3⁺CD8⁺ T lymphocyte or high NK cell count as well as high Charlton score are more likely to have nosocomial infection.

Recent studies suggest that long noncoding RNAs (lncRNAs) play critical roles in cancer progression and immune modulation, emerging as potential therapeutic targets. In this study, we investigated the expression and functional role of LINC00892 in LUAD using RNA sequencing data from The Cancer Genome Atlas (TCGA) and functional assays in vitro and in vivo. We found that LINC00892 is significantly downregulated in LUAD tissues compared to normal tissues, and lower LINC00892 expression correlates with poorer overall survival (OS), disease-specific survival (DSS), and progression-free interval (PFI), particularly in younger patients and those with early-stage disease. Bioinformatic analyses revealed that LINC00892 expression is positively correlated with immune cell infiltration, including CD4⁺ and CD8⁺ T cells, and negatively correlated with tumor-promoting Th2 cells, suggesting its role in shaping the tumor immune microenvironment. In vitro functional assays showed that LINC00892 overexpression inhibits LUAD cell proliferation, migration, and invasion while promoting apoptosis. Mechanistically, LINC00892 upregulation was found to suppress epithelial-mesenchymal transition (EMT) by increasing E-cadherin expression and decreasing levels of N-cadherin, vimentin, and slug. Additionally, in an in vivo mouse xenograft model, LINC00892 overexpression suppressed tumor growth and metastasis, accompanied by enhanced immune cell infiltration such as CD4⁺ and CD8⁺ T cells. Collectively, these findings suggest that LINC00892 acts as a tumor suppressor in LUAD by modulating immune infiltration and EMT, highlighting its potential as a prognostic biomarker and therapeutic target.</p>","PeriodicalId":15952,"journal":{"name":"Journal of Immunology Research","volume":"2025 ","pages":"4341348"},"PeriodicalIF":3.5,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12041620/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144008189","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}

Currently, there is no effective preventive vaccine for &lt;i&gt;B. canis&lt;/i&gt;. Control measures include diagnostic testing, isolation, and euthanasia of infected animals. However, these measures face significant limitations, such as diagnostic challenges, ethical concerns, and limited success in preventing transmission. Epidemiologically, canine brucellosis exhibits seroprevalence rates ranging from less than 1% to over 15%, with higher rates reported in stray dogs and regions of low socioeconomic development. This study employed a reverse vaccinology approach to design and characterize a multiepitope vaccine candidate against &lt;i&gt;B. canis&lt;/i&gt;, aiming to prevent infection caused by this pathogen. A comprehensive in silico analysis of the complete &lt;i&gt;B. canis&lt;/i&gt; proteome was conducted to identify proteins with potential as vaccine targets. Predicted epitopes for B and T cells were analyzed, and those with the highest capacity to elicit a robust immune response were selected. These proteins were classified as plasma membrane proteins, outer membrane proteins (OMPs), or proteins with similarity to virulence factors. Selection criteria emphasized their essential roles in bacterial function, lack of homology with proteins from dogs or mice, and presence of fewer than two transmembrane domains. From this process, four candidate proteins were identified. Epitopes for B and T cells within these proteins were predicted and analyzed, selecting the most immunogenic sequences. The overlap between B- and T-cell epitopes narrowed the selection to six final epitopes. These selected epitopes were then assembled into a multiepitope vaccine construct using flexible linkers to ensure structural integrity and molecular adjuvants to enhance immunogenicity. The physicochemical properties, antigenicity, and toxicity of the designed vaccine were evaluated. Additionally, the secondary and tertiary structure of the vaccine was predicted and refined, followed by a molecular interaction analysis with the Toll-like receptor 4 (TLR4) receptor. The designed vaccine proved to be highly antigenic, nonallergenic, and nontoxic. Validation of its secondary and tertiary structures, along with molecular docking analysis, revealed a high binding affinity to the TLR4 receptor. Molecular dynamics simulations and normal mode analysis further confirmed the vaccine's structural stability and binding capacity. A multiepitope vaccine candidate against &lt;i&gt;B. canis&lt;/i&gt; was successfully designed and characterized using a reverse vaccinology approach.
