Progresses on mechanism of the relationship between gut microbiota and radiation injuries

Recently, researchers have paid attention to the relationship between gut microbiota and human health and attempted to investigate the effect of gut microbiota on radiation injury. More and more evidence showed that normal gut microbiota could maintain human health through Toll-like receptors, immune system and inflammatory reaction. Improvements of gut microbiota spectrum and its balance have become an effective strategy for the treatment of certain diseases. This paper reviewed the relationship between gut microbiota and radiation injury and underlying mechanisms, in order to provide novel theoretical evidence and guideline for the therapy of radiation enteritis and other diseases. Key words: Gut microbiota; Radiation injuries; Toll-like receptors
