Who could benefit from this research
✓Could help
Ideal candidates are adults aged 21 and older who have experienced a traumatic brain injury.
✕Less likely to help
Individuals without a traumatic brain injury or those unable to participate in gut microbiome transfer procedures may not benefit.
What this research studies
This project looks at whether transferring a healthy gut microbiome can lessen brain damage and improve thinking and movement after a brain injury in older adults. It builds on animal studies showing age-related differences in gut bacteria after injury and how a young microbiome might help. The study will use single-cell RNA sequencing to understand how brain immune cells respond over time after treatment in aged mice, laying the groundwork for future human work. The overall aim is to identify a new, gut-based approach to reduce neurodegeneration and cognitive problems after injury in older patients.
Why it matters
Potential benefit: If successful, this research could lead to new gut-based therapies that improve recovery and cognitive function after brain injury in older adults.
How similar studies have gone: Preclinical studies in mice suggest that transferring a healthy microbiome can attenuate neurodegeneration after brain injury.
