Objective:
To synthesize laboratory and clinical perspectives on the interaction between spinal cord injury and gut microbiota.
Approach:
Key Findings:
- Spinal cord injury disrupts intestinal function and triggers gut microbiota imbalance.
- Gut microbiota can produce metabolites that exacerbate neuroinflammation in the spinal cord.
- The relationship between gut microbiota dysbiosis and spinal cord injury is bidirectional.
- A significant reduction in butyrate-producing bacteria and increased pro-inflammatory cytokines have been observed post-SCI.
Interpretation:
This review highlights the complex interplay between gut microbiota and spinal cord injury.
Limitations:
- Standardized and effective clinical treatments for gut microbiota modulation in SCI remain elusive.
- Current research may not fully address the translational bottlenecks and safety risks associated with microbiota interventions.
Conclusion:
This study provides insights into the mechanisms linking spinal cord injury and gut microbiota.
