Temporal Profiles Dissociate Regional Extracellular Ethanol versus Dopamine Concentrations
In vivo monitoring of dopamine via microdialysis has demonstrated that acute, systemic ethanol increases extracellular dopamine in regions innervated by dopaminergic neurons originating in the ventral tegmental area and substantia nigra. Simultaneous measurement of dialysate dopamine and ethanol allows comparison of the time courses of their extracellular concentrations. Early studies demonstra...
متن کاملNonclassical Pharmacology of the Dopamine Transporter: Atypical Inhibitors, Allosteric Modulators, and Partial Substrates s
The dopamine transporter (DAT) is a sodium-coupled symporter protein responsible for modulating the concentration of extraneuronal dopamine in the brain. The DAT is a principle target of various psychostimulant, nootropic, and antidepressant drugs, as well as certain drugs used recreationally, including the notoriously addictive stimulant cocaine. DAT ligands have traditionally been divided int...

متن کاملUptake inhibitors but not substrates induce protease resistance in extracellular loop two of the dopamine transporter.
Changes in protease sensitivity of extracellular loop two (EL2) of the dopamine transporter (DAT) during inhibitor and substrate binding were examined using trypsin proteolysis and epitope-specific immunoblotting. In control rat striatal membranes, proteolysis of DAT in a restricted region of EL2 was produced by 0.001 to 10 microg/ml trypsin. However, in the presence of the dopamine uptake bloc...
متن کاملDopamine Transporter Efflux in ADHD
Elevated dopamine efflux through the dopamine transporter may underlie some forms of attention-deficit hyperactivity disorder (ADHD), according to MazeiRobison et al. The authors identified a mutant form of dopamine transporter in two siblings with ADHD and expressed the mutant and wild-type forms in HEK-293T cells. Although expression levels and dopamine uptake were similar for mutant and wild...
