TGR5 (Gpbar‐1) is a membrane‐bound bile acid receptor in the gastrointestinal tract and immune cells with pleiotropic actions. As shown in the present study, TGR5 is also expressed in astrocytes and neurons. Here, TGR5 may act as a neurosteroid receptor, which is activated by nanomolar concentrations of 5β‐pregnan‐3α‐ol‐20‐one and micromolar concentrations of 5β‐pregnan‐3α‐17α‐21‐triol‐20‐one and 5α‐pregnan‐3α‐ol‐20‐one (allopregnanolone). TGR5 stimulation in astrocytes and neurons is coupled… Expand

TLDR
The bile acid receptor GPBAR1/TGR5 could be a new therapeutic target for pathologies coursing with neuroinflammation and microglia activation, such as traumatic brain injuries, stroke, or neurodegenerative diseases. Expand
Bile Acid-Activated Receptors: GPBAR1 (TGR5) and Other G Protein-Coupled Receptors.
TLDR
In liver injury models, inhibitors of S1PR2 signaling and agonists for TGR5 have been employed to attenuate liver injury in rodent models for cholestasis, nonalcoholic steatohepatitis, and fibrosis/cirrhosis. Expand
Perspective: TGR5 (Gpbar-1) in liver physiology and disease.
TLDR
Activation of TGR5 promotes intestinal glucagon-like peptide-1 (GLP-1) release, thereby modulating glucose homeostasis and energy expenditure in brown adipose tissue and skeletal muscle, and exerts anti-inflammatory actions resulting in decreased liver injury in animal models of sepsis. Expand
TGR5 ligands as potential therapeutics in inflammatory diseases
TLDR
TGR5 exerts antiinflammatory actions by decreasing adhesion molecule expression in endothelial cells and inhibiting proinflammatory cytokine production in macrophages and the currently known agonists of TGR5 are described. Expand

Stimulation of Brain Pregnenolone Synthesis by Mitochondrial Diazepam Binding Inhibitor Receptor Ligands In Vivo
TLDR
Treatment with the MDR ligands 4‐CD and FGIN‐1–27 increased the pregnenolone content in the brain but failed to change the plasma or peripheral tissue content of this steroid, suggesting that glial cell MDRs play a role in neurosteroid biosynthesis in vivo. Expand
The membrane‐bound bile acid receptor TGR5 is localized in the epithelium of human gallbladders
TLDR
A role for TGR5 in bile acid–induced fluid secretion in biliary epithelial cells is suggested, and the presence of the receptor in both the plasma membrane and the recycling endosome indicate that T GR5 can be regulated by translocation. Expand
The G‐protein coupled bile salt receptor TGR5 is expressed in liver sinusoidal endothelial cells
TLDR
The data suggest that SEC are directly responsive toward specific bile salts, and Regulation of eNOS in SEC by TGR5 connects bile salt with hepatic hemodynamics, of particular importance in cholestatic livers when bile Salt concentrations are increased. Expand
A G Protein-coupled Receptor Responsive to Bile Acids*
TLDR
It is found that a novel G protein-coupled receptor, TGR5, is responsive to bile acids as a cell-surface receptor, and was abundantly expressed in monocytes/macrophages in human and rabbit. Expand
Bile acids induce energy expenditure by promoting intracellular thyroid hormone activation
TLDR
It is shown that the administration of BAs to mice increases energy expenditure in brown adipose tissue, preventing obesity and resistance to insulin, and indicates that BAs might be able to function beyond the control of BA homeostasis as general metabolic integrators. Expand

TLDR
This work has shown that G protein coupled bile acid receptor 1 is a membrane‐bound G‐protein‐coupled receptor that can mediate the rapid, transcription‐independent actions of BAs. Expand
