Bile acids and gut graft‑versus‑host disease

The role of bile acid metabolomics in graft-versus-host disease

NIH-funded research Beckman Research Institute/city of Hope · NIH-11310114

Researchers will measure bile acids and related metabolites to find how they affect gut graft‑versus‑host disease in people who’ve had allogeneic stem cell transplants.

What this research studies

This project will analyze blood and stool samples from people who have had allogeneic hematopoietic cell transplants to map bile acid changes linked to gastrointestinal GVHD. The team will combine gut microbiome sequencing, immune cell testing, and metabolomics to see how bile acids, gut bacteria, and immune responses interact. They will also use animal models to test whether specific bile acid patterns can worsen or protect against GVHD. Results will be compared with prior multi-center patient data to look for biomarkers and potential treatment targets.

Who could benefit from this research

Good fit: Ideal candidates are people who have received or will receive an allogeneic hematopoietic cell (stem cell) transplant, especially those with or at risk for gastrointestinal GVHD.

Not a fit: Patients who have not had an allogeneic transplant or who only have non‑GI conditions are unlikely to benefit directly from this research.

Why it matters

Potential benefit: If successful, this could lead to new biomarkers or therapies that reduce gut GVHD severity and improve recovery after transplant.

How similar studies have performed: Previous patient and animal studies from this group and others have linked gut microbiome changes to GVHD and survival, so this bile‑acid focused work builds on encouraging prior evidence though clinical interventions remain experimental.
