Deoxycholic acid promotes anxiety- and depression-like behaviors in mice via modulation of the gut microbial metabolite indole-3-propionic acid
Clinical Report: Deoxycholic Acid Influences Anxiety and Depression Behaviors in Mice
Overview
This study investigates the role of deoxycholic acid (DCA) in inducing anxiety- and depression-like behaviors in mice through alterations in gut microbiota and metabolites, specifically focusing on the mechanisms involved. Key findings indicate that DCA reduces levels of indole-3-propionic acid (IPA), which is linked to emotional and behavioral abnormalities.
Background
High-fat diets (HFD) are associated with both metabolic and neurobehavioral disorders, including anxiety and depression. Understanding the mechanisms by which HFD influences emotional health is critical, particularly the role of gut-derived metabolites in the gut-brain axis. This study sheds light on how DCA, a bile acid elevated by HFD, may mediate these effects.
Data Highlights
No numerical data available. Consider including key numerical findings from the study to support the conclusions drawn.
Key Findings
DCA intervention induced anxiety- and depression-like behaviors in mice.
Reduction of Clostridium_sensu_stricto_1 and its metabolite IPA was observed with DCA treatment.
IPA supplementation restored IPA levels and ameliorated DCA-induced emotional abnormalities.
Behavioral and physiological changes were similar in mice receiving fecal microbiota transplantation from DCA model mice.
Targeting bile acid metabolism or restoring IPA function may be potential intervention strategies for HFD-related emotional disorders.
Clinical Implications
The findings suggest that interventions targeting bile acid metabolism or restoring gut microbial metabolites like IPA could be beneficial in managing HFD-related anxiety and depression. Clinicians should consider the gut-brain axis when addressing emotional disorders in patients with dietary concerns, and explore practical applications of these findings in treatment plans.
Conclusion
This study highlights a potential gut-brain pathway linking HFD-induced DCA elevation to anxiety and depression in mice, emphasizing the importance of gut microbiota and metabolites in emotional health.
