Who could benefit from this research
✓Could help
Veterans with deployment-related GI or liver conditions, particularly those with inflammatory bowel disease and PTSD.
✕Less likely to help
Participants without GI or liver disease or without PTSD may have limited direct benefit.
What this research studies
This project examines how the gut microbiome interacts with PTSD and host biology to affect diarrhea, gut inflammation, and liver disease in veterans. It uses a collaborative, translational approach across multiple teams to study microbiome changes, gut barrier function, and immune responses in affected individuals. The goal is to identify biological pathways and potential targets that connect deployment-related stress to GI and liver conditions, with an emphasis on care-relevant findings for veterans. Researchers will integrate clinical data, biological samples, and advanced analyses to map how PTSD and gut microbes contribute to disease susceptibility and progression.
Why it matters
Potential benefit: If successful, findings could lead to new strategies to prevent or treat GI and liver problems in veterans who have PTSD and gut dysbiosis.
How similar studies have gone: Prior studies show the gut microbiome influences GI diseases, but this program directly links PTSD and deployment exposure to gut-related conditions in veterans, representing a novel integration.
