AI Summary

A study in Proceedings of the National Academy of Sciences examined how the filamentous gut fungus Mucor racemosus affects radiation injury in mice. Mice inoculated with M. racemosus showed enhanced protection against radiation‑induced DNA damage and reduced intestinal injury compared with untreated controls. The research highlights that, unlike the bacterial focus of most microbiome work, certain filamentous fungi can reside in intestinal crypts and produce compounds that mitigate inflammation and tissue damage. This suggests a broader role for gut fungi in health and disease.
