Identification of BA-activated G-protein-coupled receptors (GPCRs), Takeda GPCR 5 (TGR5, also known as GPBAR1) and sphingosine-1 phosphate receptor 2 (S1PR2), has made a significant advance by linking BAs with various metabolic diseases, including NAFLD [17,18,19]. Here, S1PR2 is linked to metabolic dysfunction-associated steatotic liver disease.
