The membrane‐bound bile acid receptor TGR5 is localized in the epithelium of human gallbladders
Verena Keitel, Kenko Cupisti, Christoph Ullmer, Wolfram T. Knoefel, Ralf Kubitz, Dieter Häussinger – 27 August 2009 – TGR5 (Gpbar‐1) is a plasma membrane‐bound, G protein–coupled receptor for bile acids. TGR5 messenger RNA (mRNA) has been detected in many tissues, including rat cholangiocytes and mouse gallbladder. A role for TGR5 in gallstone formation has been suggested, because TGR5 knockout mice did not develop gallstones when fed a lithogenic diet. In this study, expression and localization of TGR5 was studied in human gallbladders.
