Using engineered probiotics to reduce radiation injury effects

LR-IL-22 for Mitigation and Management of Radiation Injuries

NIH-funded research University of Pittsburgh at Pittsburgh · NIH-11293162

This study is looking at how a special probiotic called Lactobacillus reuteri might help protect your gut and help it heal after radiation exposure, and it will also test if combining it with other treatments makes it work even better.

What this research studies

This research investigates how a specially engineered probiotic, Lactobacillus reuteri, can help mitigate the harmful effects of radiation exposure on the gastrointestinal system. By administering this probiotic orally, the study aims to enhance the recovery of intestinal stem cells that are damaged by radiation. The approach focuses on restoring the levels of a protective molecule called IL-22, which is crucial for gut health and recovery after radiation exposure. The research will also explore the combination of this probiotic with other treatments to improve its effectiveness.

Who could benefit from this research

Good fit: Ideal candidates for this research include individuals who have experienced total or partial body irradiation, such as cancer patients undergoing radiation therapy.

Not a fit: Patients who have not been exposed to radiation or those with pre-existing gastrointestinal conditions may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could significantly improve recovery outcomes for patients suffering from radiation injuries.

How similar studies have performed: Previous research has shown promise in using probiotics for gut health, but this specific approach with engineered Lactobacillus reuteri is novel.
