Immune Cells “Remember” Gut Infections and Rapidly Mobilize to the Brain, Study Finds Expanded Text: New research shows that immune cells originating in the gut can recall past stomach infections and quickly migrate to the brain when similar pathogens appear. This discovery reveals a previously unknown communication pathway between the digestive system and the central nervous system. Scientists say the mechanism may help explain how gastrointestinal illnesses influence neurological conditions, opening new possibilities for treating inflammation‑related brain disorders.
