Locomotor sensitization induced by the dopamine agonist quinpirole can be potentiated by co-treatment with the synthetic kappa opioid agonist U69593. The identification of salvinorin A, an active component of the psychotropic sage Salvia divinorum, as a structurally different agonist of kappa-opioid receptors raised the question of whether this compound(More)
Bioluminescence resonance energy transfer (BRET)-based biosensors have been extensively used over the last decade to study protein-protein interactions and intracellular signal transduction in living cells. In this review, we discuss the various BRET biosensors that have been developed to investigate biology, pharmacology, and signaling of G protein-coupled(More)
Trace-amines (TAs) are endogenous amines that are implicated in several physiological processes including modulation of aminergic neurotransmission. These compounds exert their effect by activating a class of G protein-coupled receptors termed Trace-Amine Associated Receptors (TAARs), where TAAR1 is the only human receptor that has been shown to bind(More)
A number of pathological conditions have been linked to mutations in the dopamine transporter gene, including hereditary dopamine transporter deficiency syndrome (DTDS). DTDS is a rare condition that is caused by autosomal recessive loss-of-function mutations in the dopamine transporter (DAT), which often affects transporter trafficking and folding. We(More)
