Sepsis T-Cell Gene Signatures and Drug Predictions

Integrated bioinformatics analysis identifies 330 overlapping differentially expressed genes and 10 T-cell-related hub genes (CD4, CD247, CD3E, CD2, FYN, ZAP70, CD3G, ITK, LAT, CD5) from three blood transcriptomic datasets. The study validates these genes as down-regulated in sepsis patients and predicts six potential therapeutic agents via cMAP analysis. The 11.8 KB file contains the research findings in a DOCX format.

Use Cases

• Validate the diagnostic performance of the 10 hub genes (e.g., CD4, CD3E, ZAP70) for early sepsis detection using independent datasets.
• Analyze the correlation between hub gene expression levels and metrics of T-cell exhaustion or myeloid cell infiltration.
• Investigate the six predicted therapeutic agents (e.g., anastrozole, etofenamate) from the cMAP analysis for drug repurposing strategies in sepsis.
• Perform functional enrichment analysis on the 330 overlapping differentially expressed genes to explore immune pathways like T-cell receptor signaling.

Strengths

• Identifies 330 overlapping differentially expressed genes from three independent transcriptomic datasets (GSE95233, GSE137340, GSE57065).
• Pinpoints 10 specific hub genes central to T-cell function, validated for significant down-regulation in sepsis patients.
• Predicts six potential therapeutic agents via cMAP analysis, offering a theoretical framework for drug repurposing.

Limitations

• The dataset is a small 11.8 KB DOCX file containing summarized analysis results, not the underlying raw transcriptomic data.
• High diagnostic accuracy (AUC: 0.908–0.999) of hub genes may reflect immune cell composition differences rather than disease-specific molecular signatures.
• No raw gene expression values, sample-level data, or columnar data structure is provided for direct computational analysis.
