Summary
This study identifies Interleukin-1 beta (IL1B) as a key inflammatory driver in panic disorder (PD) using induced microglia-like cells. Targeting this IL1B network may lead to new therapies and biomarkers for PD.
Area of Science:
- Neuroimmunology
- Psychiatric Disorders
- Transcriptomics
Background:
- Panic disorder (PD) lacks objective biomarkers and its neuroimmune mechanisms are poorly understood.
- Induced microglia-like cells (iMGs) from peripheral blood offer a novel model to investigate immune pathways in PD.
Purpose of the Study:
- To define the peripheral immune transcriptomic signature in PD.
- To identify the core regulatory network in PD using iMG transcriptomic data.
Main Methods:
- Differential gene expression analysis of transcriptomic data from iMGs of PD patients and healthy controls.
- Functional enrichment analysis and protein-protein interaction (PPI) network construction.
- Hub gene screening within the identified network.
Main Results:
- Identified 255 differentially expressed genes (DEGs) in PD iMGs, enriched in immune and inflammatory pathways.
- The "cytokine-cytokine receptor interaction" and "chemokine signaling pathway" were significantly associated with DEGs.
- Interleukin-1 beta (IL1B) was identified as the top hub gene, central to an inflammatory module including IL10, CCL3, and CXCL5.
Conclusions:
- Bioinformatics analysis of the iMG model highlights IL1B as a central hub in PD's dysregulated inflammatory network.
- This finding provides a mechanistic link for elevated IL-1β in PD patients.
- Targeting the IL1B-driven inflammatory network presents potential therapeutic and biomarker discovery avenues for PD.
