Melatonin-induced restoration of the intestinal mucosal barrier in inflammatory bowel disease via activation of the SIRT1-LKB1-pAMPK axis
To evaluate the efficacy and investigate the mechanisms of melatonin in repairing the intestinal mucosal barrier in inflammatory bowel disease (IBD).
Key Findings:
IBD patients exhibited lower serum melatonin and fecal 2-oxomelatonin levels, indicating a potential deficiency.
Melatonin enhanced intestinal antimicrobial peptides and significantly alleviated colitis symptoms.
Melatonin restored the abundance of the beneficial probiotic Akkermansia while decreasing the harmful pathogen Desulfovibrio.
Melatonin upregulated SIRT1 and pAMPK in mouse colonic tissues, suggesting a pathway for its protective effects.
Inhibitors of SIRT1 and pAMPK abolished the protective effects of melatonin, confirming its mechanism of action.
Interpretation:
Melatonin may ameliorate colitis by regulating gut microbiota, modulating antimicrobial peptide secretion, and reinforcing intestinal epithelial barrier integrity through the SIRT1-LKB1-pAMPK pathway.
Limitations:
The study primarily focused on animal and cell models, which may limit the direct applicability of findings to human IBD.
The sample size for clinical analysis was relatively small, which may affect the robustness of the conclusions.
Conclusion:
Melatonin shows potential as a therapeutic agent for IBD by enhancing gut health through specific molecular pathways.
