TLS are comprised of a T-cellular compartment and a B-cellular compartment, the latter encompassing follicular dendritic cells (FDCs), high endothelial venules (HEVs), and lymphatic vessels. While T helper cells predominate in cancer TLS, the specific functions of their subpopulations remain inadequately understood.

B lymphocyte activation is succeeded by class recombination (CSR) and somatic hypermutation (SHM). Dendritic cells (DCs) constitute a vital cellular component of the TLS T compartment. During steady state and early stages of CRC, specialized antigen-presenting cells such as DCs migrate to regional lymph nodes through afferent lymphatics. They deliver MHC antigen-derived peptide complexes (tumor antigens) to naïve CD4<sup>+</sup> and CD8<sup>+</sup> T cells, which subsequently infiltrate the tumor site as antigen-specific T cells. Key DC markers studied in TLS include CD83 and DC-LAMP. Research has indicated that the DC-LAMP gene signature in tumor TLS reflects Th1 cell targeting, cytotoxicity, and T cell activation.

Current research indicates the expression of MDA5, encoded by <i>IFIH1</i>, is associated with increased immunity to COVID-19 in children. Children are also known to have a much lower risk of developing leukemia. Our hypothesis is that <i>IFIH1</i> and its regulatory miRNAs are biomarkers associated with pediatric leukemia; the objective of our study is to identify genes, through miRNA targeting mechanisms, which may be biomarkers associated with COVID-19 infection and leukemia. The database TarBase was analyzed to identify miRNAs that target <i>IFIH1</i>, followed by the identification of other genes regulated by <i>IFIH1</i>'s targeting miRNAs, to construct a gene-miRNA targeting network. Protein-Protein Interaction (PPI) analysis and DAVID/KEGG pathway analysis were conducted to identify genes with meaningful biological interactions and pathways. We identified two significant miRNAs, <i>hsa-196a-5p</i> and <i>hsa-196b-5p</i>, and 51 of their targeted and highly expressed genes reported in the Acute Myeloid Leukemia (AML) samples from The Cancer Genome Atlas (TCGA) RNA sequencing database. When conducting additional analysis using the Gene Constellation module of the Immunological Genome Project for the top three candidate genes, several other genes were identified to be highly correlated with <i>STAT3</i> and <i>IFIH1</i> in our study. Based on our investigation into co-expression analysis, we found that <i>IFIH1</i> is a potential biomarker for AML. We are expanding our work to create a machine learning model to identify other biomarkers, examine the significance of various parameters (age, race, etc.), and perform comorbidity network analysis for other potential genes/miRNAs.</p>","PeriodicalId":72163,"journal":{"name":"American journal of clinical and experimental immunology","volume":"13 6","pages":"246-258"},"PeriodicalIF":1.4,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11744346/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143017219","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}
