Research Summary: A novel membrane-bound G protein-coupled receptor, TGR5, is involved in modulating gastrointestinal functions such as secretion and motility. TGR5 receptor regulates glucose and energy homeostasis and maintains gastrointestinal integrity. Bile acids, apart from aiding nutrient absorption, are important signaling molecules with paracrine and endocrine functions. They act as ligands for the TGR5 receptor, influencing secretion, motility, and glucose regulation through cAMP/PKA, Ca²⁺/PKC, MAP kinase, and tyrosine kinase pathways. Understanding the molecular mechanisms underlying TGR5-induced functions has therapeutic potential for controlling weight gain and improving glucose homeostasis. Dr. Senthilkumar’s research demonstrates that in gastric smooth muscle, TGR5 receptors are coupled to the Gαs/cAMP pathway, where activation leads to muscle relaxation via PKA-dependent phosphorylation of RhoA and Epac-dependent stimulation of Rap1.
