Gut microbiome imbalance and body-wide brain inflammation linked to traumatic brain injury severity

The gut-brain axis is increasingly implicated in the effects of traumatic brain injury (TBI).

• Few human studies have explored the relationship between gut metagenomics and cytokine levels in TBI patients.
• This limitation hinders understanding of how gut health may affect recovery from TBI.
• The impact of varying severity levels of TBI on gut health and immune response remains under-investigated.
