Fecal Microbiota from Social Anxiety Disorder Patients Induces Anxiety-Like Behavior in Mice
This experimental study transplanted fecal microbiota from patients with social anxiety disorder into antibiotic-treated mice and observed increased anxiety-like behaviors alongside altered gut microbial composition (enriched Bacteroidota, reduced butyrate producers) and metabolic changes. The findings provide mechanistic evidence for a gut-microbiota link in anxiety disorders, though results in animal models require validation in human studies before clinical application.
