Abstract:
The adhesion G-protein coupled receptors (aGPCRs) are a family of 33 G-protein receptors consisting of ADGRA1-3, ADGRB1-3, ADGRC1-3, ADGRD1-2, ADGRE1-5, ADGRF1-5, ADGRG1-7, ADGRL1-4, and ADGRV1. Recent studies have unveiled the role of aGPCRs in numerous brain functions, including in neurodevelopment, synapse formation and maintenance, establishment of the blood-brain barrier, and myelination. Further, dysfunction of aGPCRs have been associated with disorders such as gliomas, depression, and epilepsy, among many others. Herein, we review generalized properties of aGPCRs, their brain-specific expression, associations with neurological and psychiatric diseases, and potential as future pharmacological targets.

G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...
