As research on the microbiome in central nervous system disorders progresses, the role of gut microbiota in spinal cord injury has garnered significant attention. Spinal cord injury disrupts intestinal function and triggers an imbalance in gut microbiota, while metabolites produced by gut microbiota can cross the blood-spinal cord barrier into the central nervous system, exacerbating neuroinflammation in the spinal cord. The relationship between gut microbiota dysbiosis and spinal cord injury is bidirectional. In recent years, the proposal of the \u2018gut microbiota-gut-spinal cord\u2019 axis theory has led to increased interest in the impact of gut microbiota on spinal cord injury. Gut microbiota not only serve as biomarkers for the severity of spinal cord injury but also represent potential therapeutic targets. Current research primarily focuses on the alterations in gut microbiota following spinal cord injury and the potential effects of microbiota-derived metabolites\u2014such as aryl hydrocarbon receptor agonists and short-chain fatty acids\u2014on secondary inflammatory responses post-injury. Although numerous studies have utilized various approaches to modulate gut microbiota to promote functional recovery after spinal cord injury, standardized and effective clinical treatments remain elusive. This review synthesizes laboratory and clinical perspectives on the mechanisms underlying the interaction between spinal cord injury and gut microbiota, aiming to provide novel insights for the therapy of spinal cord injury.<\/jats:p>","DOI":"10.3389\/fimmu.2026.1742885","type":"journal-article","created":{"date-parts":[[2026,6,19]],"date-time":"2026-06-19T04:29:53Z","timestamp":1781843393000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Bidirectional
