Review details dopamine transporter kinetics and binding sites in the brain, highlighting therapeutic targets for neurodegenerative disorders and cocaine addiction.

Key Points

To characterize the molecular, functional, and biochemical properties of the dopamine transporter and evaluate its role in neuropsychiatric disease pathology and addiction.
Evaluated functional dopamine reuptake and reverse transport dynamics across synaptic membranes under varying ionic conditions.
Assessed dopamine transporter binding site distribution and affinities using radiolabeled [3H]cocaine and GBR-series piperazine ligands across anatomical brain regions.
Dopamine transporter facilitates bidirectional dopamine movement and serves as a presynaptic marker for altered innervation in Parkinson's disease, MPTP neurotoxicity, and progressive supranuclear palsy.
Cocaine exhibits heterogeneous, anatomically distinct distributions of high- and low-affinity binding sites across brain regions that correlate with distinct ligand-binding profiles.
