Abstract
The thyrotropin receptor (TSHR), the lutropin- (LHR), and the follicotropin receptor (FSHR) belong to glycoprotein hormone receptors (GPHR), a subgroup of the class A G-protein coupled receptors. In this review, the unique features of GPHR have been taken into account for their pharmacological interventions: i) The respective hormone and stimulating or blocking antibodies are binding on the large ectodomain that is ii) via a hinge region, containing iii) an internal tethered agonist linked to the transmembrane domain. iv) Multimerization and mechanisms for negative or positive cooperativity of GPHR upon ligand binding and v) dimer- and oligomeric arrangements enabling trans-activation on GPHR signaling are considered. Available knowledge concerning the modulation of the GPHR (mal)-function and associated structural aspects by diverse entities such as antibodies, chaperones, peptides, small molecule agonists, inverse agonists, and antagonists is summarized. The TSHR is important with respect to autoimmune [Graves’ disease (GD), Graves’ orbitopathy (GO)] or non-autoimmune thyroid dysfunctions and cancer-development. To date there is neither an agonist nor antagonist modulator of pathogenic such as TSHR signaling in the clinics. However, several different ligands monoclonal stimulating and inhibiting antibodies and small molecule drug-like ligands have been reported in the last decade. In special focus are the most recent findings regarding the development and use of small molecule TSHR ligands. Finally, limitations of current knowledge and lack of information are discussed highlighting the need for intensified efforts towards understanding the interplay of TSHR multimers, especially their interaction with drug-like ligands. Important in this context is the biased ligand development.
