Using Lactobacillus to reduce gastrointestinal damage from radiation exposure

Official title: Mitigation of GI-ARS by Lactobacillus species

Funded at University of Tennessee Health Sci Ctr · NIH-10991008 · Data updated 2026-11-12

This study is looking at how certain friendly bacteria, called Lactobacillus, might help protect your gut from damage caused by radiation, especially if you've experienced gastrointestinal issues from it, and it hopes to find new ways to help you recover better.

Who could benefit from this research

Could help

Ideal candidates for this research include individuals who have been exposed to radiation or are at risk of exposure, such as those involved in nuclear incidents or certain medical treatments.

Less likely to help

Patients who have not been exposed to radiation or do not have gastrointestinal issues related to radiation exposure may not benefit from this research.

What this research studies

This research investigates how specific Lactobacillus species can help protect the gut from damage caused by radiation exposure, particularly in cases of Gastrointestinal Acute Radiation Syndrome (GI-ARS). The study focuses on understanding how radiation alters the gut microbiome and identifying the mechanisms behind this process. By administering Lactobacillus casei and plantarum after radiation exposure, the research aims to mitigate gut barrier dysfunction and inflammation. Patients may benefit from insights into new treatments that could improve recovery from radiation-related injuries.

Why it matters

Potential benefit: If successful, this research could lead to new therapeutic options for patients suffering from gastrointestinal damage due to radiation exposure.

How similar studies have gone: Other research has shown promise in using probiotics to support gut health, suggesting that this approach may be viable for mitigating radiation effects.
