Protecting gut mucus to prevent complications after allogeneic stem cell transplant

Mucin preserving strategies to reduce allo HCT toxicities

NIH-funded research Beckman Research Institute/city of Hope · NIH-11196064

This project tests ways to protect the gut’s mucus layer to help people having allogeneic stem cell transplants have fewer gut complications and infections.

What this research studies

After donor (allogeneic) stem cell transplants, antibiotics and certain gut bacteria can erode the colon’s protective mucus and contribute to graft‑versus‑host disease (GVHD), neutropenic fever, and infections. Researchers will analyze stool and tissue samples from transplant patients and run laboratory and mouse experiments to find approaches that preserve mucin, the mucus layer that protects the gut. Strategies include examining antibiotic choices and targeting mucus‑degrading bacteria such as Bacteroides and Akkermansia. The project combines patient sample analysis, microbial and genetic studies, and preclinical testing of mucus‑protective interventions.

Who could benefit from this research

Good fit: People scheduled for or recently having undergone allogeneic hematopoietic stem cell transplantation, particularly those receiving broad‑spectrum antibiotics, are the most relevant candidates.

Not a fit: People not undergoing allogeneic stem cell transplant or whose problems are unrelated to gut microbes or mucus are unlikely to benefit directly.

Why it matters

Potential benefit: Could reduce intestinal GVHD, neutropenic fever, infections, and transplant‑related complications if mucus preservation strategies work.

How similar studies have performed: Prior patient and mouse studies have linked mucus‑degrading bacteria and certain antibiotics to worse GVHD and neutropenic fever, so this project builds on emerging evidence though protective therapies are still experimental.
