Bifidobacterium longum Depletion and Bile Acid Dysregulation in MASLD: Links to Hepatic TGR5–AMPK Signaling
Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease worldwide. Although gut microbiota dysbiosis and aberrant bile acid metabolism are central to MASLD pathogenesis, the critical keystone species and precise molecular mechanisms remain elusive. Here, we performed an...
