Identification and Functional Assessment of Critical Genes in Macrophage M1 Polarization Induced by Helicobacter Pylori: Implications for Migraine-Related Functional Dyspepsia
To investigate the specific molecular mechanisms linking Helicobacter pylori infection to migraine and functional dyspepsia through the assessment of macrophage M1 polarization and associated genes.
Key Findings:
Identified 683 DEGs enriched in immune and inflammatory pathways in H. pylori-infected patients, which may contribute to migraine and functional dyspepsia.
Prominent M1 macrophage polarization was observed with increased γδT cells and B lymphocytes, indicating a potential immune response.
Four CGRP-related hub genes (PNOC, ICAM1, MMP9, NFE2L1) were upregulated in H. pylori-infected macrophages, suggesting their role in the pathophysiology of these conditions.
PNOC, ICAM1, and MMP9 positively correlated with M1 macrophages, while NFE2L1 showed no significant correlation, indicating varying roles in macrophage polarization.
PNOC knockdown in macrophages reduced CALCA expression in co-cultured neurons, highlighting its potential regulatory role in neuroimmune signaling.
Interpretation:
H. pylori infection may drive migraine and functional dyspepsia through gastric inflammation and neuroimmune signaling, implicating specific genes in M1 macrophage polarization and CGRP modulation, which could inform future therapeutic strategies.
Limitations:
The study primarily relies on transcriptomic data, which may not fully capture protein-level changes, potentially limiting the understanding of functional outcomes.
Experimental validation was limited to specific cell types and may not represent broader physiological contexts, which could affect the generalizability of the findings.
Conclusion:
The findings suggest a gut-brain axis involvement in migraine and functional dyspepsia, highlighting the potential for therapies targeting H. pylori and CGRP pathways.
