The Role of the CCL20-CCR6 Pathway in Mediating Interactions Between Mucosal-Associated Invariant T Cells and M2 Macrophages Contributing to Immune Dysregulation in Liver Cirrhosis
To investigate the role of the CCL20-CCR6 axis in interactions between MAIT cells and macrophages during cirrhosis progression.
Approach:
Methodology: Integrated bulk and single-cell transcriptomic analyses with immunofluorescence validation.
Key Findings:
Identified eight core cirrhosis-associated immune genes, with CCL20 enriched in MAIT cells.
CCL20 was associated with activation- and exhaustion-related transcriptional profiles of MAIT cells.
The CCL20-CCR6 axis mediates interactions between MAIT cells and M2 macrophages in the cirrhotic microenvironment.
Immunofluorescence confirmed the enrichment and colocalization of CCL20, MAIT cells, and M2 macrophages in cirrhotic tissues.
Interpretation:
The CCL20-CCR6 axis is a key regulator of hepatic immune dysregulation and fibrotic progression in liver cirrhosis, suggesting its potential as a biomarker and therapeutic target.
Conclusion:
The findings highlight the role of the CCL20-CCR6 pathway in immune interactions in liver cirrhosis.
