As a bile acid (BA) membrane receptor, GPBAR1 controls the equilibrium of bile acids, the homeostasis of energy, and the metabolism of glucose. It belongs to the family of Gprotein-coupled receptors (GPCRs), which have seven transmembrane domains and use heterotrimeric G proteins to transmit extracellular signals. A detrimental regulator of NF-B-mediated liver inflammation is GPBAR1. In order to cause inflammation in the stomach, Helicobacter pylori infection upregulates the NF-B pathway. Cancer frequently develops as a result of chronic inflammation. The abnormal activation of NF-B signaling can be disrupted to significantly slow the growth of tumors.

Overview of Bile Acid Receptor
The epithelial cells of the gallbladder and bile ducts, brown adipose tissue, muscle, intestine, kidney, placenta, and brain all have significant levels of GPBAR1 expression. Sinusoidal endothelial cells, bile duct epithelial cells, and Kupffer cells in the liver all express GPBAR1, but hepatocytes do not. Although (un)conjugated deoxycholic acid, CDCA, UDCA, and cholic acid also have an effect on GPBAR1, LCA is the most potent natural agonist of GPBAR1. Adenylate cyclase is stimulated by ligand binding to GPBAR1, which raises cAMP levels and stimulates adenylate cyclase, which then activates protein kinase A and starts additional downstream signaling processes. Through the inhibition of nuclear factor κB translocation, which lowers the production of proinflammatory cytokines and mediators as well as inducible nitric oxide synthase, activation of GPBAR1 exerts anti-inflammatory effects. Glucagon-like peptide 1 (GLP-1) is secreted by enteroendocrine cells after GPBAR1 activation. This incretin enhances insulin sensitivity, insulin secretion, and pancreatic function.
Bile Acid Receptor Drug Discovery
- Liver inflammation
Although the origin of cholestasis has been extensively researched, it is still unknown how BA damages the liver. BA's proinflammatory actions are what really damage the liver during cholestasis since BA activates the hepatocytes' signaling pathway and raises the production of proinflammatory mediators.
- Metabolism and inflammation
Following meal ingestion, the microbiota transforms polysaccharides into short-chain fatty acids, amino acids, and metabolites that the host can use to produce energy. BAs are a group of significant metabolites created by microorganisms and are of the most prevalent metabolites in the intestine. They are produced from cholesterol in the liver and further processed by the gut microbiota.
