Administration of the intestine-restricted FXR agonist fexaramine (FEX) improves glucose tolerance and promotes adipose tissue browning in mice by reshaping gut microbiota to increase lithocholic acid (LCA) production, which activates TGR5/GLP-1 signaling.
This research suggests that specific bile acid signaling, influenced by gut bacteria, plays a key role in how your body handles sugar and fat storage. While this study used a specific drug (fexaramine) in mice, it highlights the importance of gut health in metabolic regulation. For now, there is no direct human supplement equivalent, but maintaining a diverse gut microbiome through diet is a logical step to support these natural pathways.
This study uncovered a mechanism in which activation of intestinal FXR shaped the gut microbiota to activate TGR5/GLP-1 signaling to improve hepatic glucose and insulin sensitivity and increase adipose tissue browning; the gut microbiota plays a critical role in bile acid metabolism and signaling to regulate metabolic homeostasis in health and disease.
Why this rating
The study uses rigorous genetic knockout models (Fxr-/-, Tgr5-/-) and antibiotic reversal to establish causality, though it is conducted in mice.
