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.

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.

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.

In recent years, researchers have extensively explored the role of the tumor immune microenvironment (TME) in CRC, highlighting the crucial influence of immune cell populations in driving tumor progression and shaping therapeutic outcomes. The TME encompasses an array of cellular and noncellular constituents, spanning tumor cells, immune cells, myeloid cells, and tumor-associated fibroblasts, among others. However, the cellular composition within the TME is highly dynamic, evolving throughout different stages of tumor progression. These shifts in cell subpopulation proportions lead to a gradual transition in the immune response, shifting from an early antitumor growth to a late-stage environment that supports tumor survival. Therefore, it is crucial to further investigate and understand the complex interactions among the various cell populations within the TME. In this review, we explore the key cellular components of varying origins, subpopulations with shared origins, and noncellular elements within the CRC TME, examining their interconnections and critical considerations for developing personalized and precise immunotherapy strategies.</p>","PeriodicalId":15952,"journal":{"name":"Journal of Immunology Research","volume":"2025 ","pages":"4109934"},"PeriodicalIF":3.5,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12008489/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143967833","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}
