This study identifies key genes and pathways involved in lymph node tuberculosis (LNTB) pathogenesis. Findings highlight potential therapeutic targets for LNTB treatment, advancing our understanding of this disease.
Area of Science:
- Immunology
- Genetics
- Molecular Biology
Background:
- Lymph node tuberculosis (LNTB) is a significant extrapulmonary form of tuberculosis.
- Understanding the molecular mechanisms underlying LNTB is crucial for developing effective treatments.
Purpose of the Study:
- To identify candidate key genes and pathways associated with LNTB.
- To elucidate the potential molecular mechanisms of LNTB development.
Main Methods:
- Analysis of gene expression profile (GSE63548) from the Gene Expression Omnibus (GEO) database.
- Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis using DAVID.
- Protein-protein interaction (PPI) network construction via STRING database and visualization with Cytoscape.
Main Results:
- 239 differentially expressed genes (DEGs) were identified.
- A miRNA (hsa-miR-4536) and 28 transcription factors (TFs) were associated with LNTB.
- Key enriched pathways include regulation of lipolysis in adipocytes, vascular smooth muscle contraction, fat digestion and absorption, NOD-like receptor, and TNF signaling.
Conclusions:
- Candidate key genes and pathways involved in LNTB pathogenesis were revealed.
- Potential therapeutic targets for LNTB treatment were identified.
- The study provides insights into the molecular mechanisms of LNTB.

The lymphatic system has two main functions: to return extracellular fluid back to the venous circulation and to expose antigenic substances to the immune system. As the collected fluid passes through lymphatic channels on its way back to the systemic circulation, it encounters multiple nodes consisting of highly concentrated clusters of...
