Molecular imaging of the dopamine transporter.
The dopamine transporter (DAT) is a transmembrane protein responsible for reuptake of dopamine from the synaptic cleft and termination of dopaminergic transmission. Several radioligands are available for DAT imaging with SPECT and PET. This review summarizes the main SPECT and PET radioligands and the main applications of DAT imaging in neuropsychiatric disorders.
متن کاملMolecular Mechanism of Dopamine Transport by Human Dopamine Transporter.
Dopamine transporters (DATs) control neurotransmitter dopamine (DA) homeostasis by reuptake of excess DA, assisted by sodium and chloride ions. The recent resolution of DAT structure (dDAT) from Drosophila permits us for the first time to directly view the sequence of events involved in DA reuptake in human DAT (hDAT) using homology modeling and full-atomic microseconds accelerated simulations....
متن کاملNigrostriatal dopamine terminal imaging with dopamine transporter SPECT: an update.
This article gives an update on nigrostriatal dopamine terminal imaging, with emphasis on SPECT performed with the presynaptic dopamine transporter (DAT) ligand (123)I-FP-CIT. The paper covers the rational use of this technique in the diagnostic work-up of patients with known or suspected parkinsonian syndromes. In detail, it addresses the impact of the method for the proof or exclusion of neur...
متن کاملDopamine Transporter SPECT Imaging in Corticobasal Syndrome
OBJECTIVE To investigate dopaminergic function in a large cohort of patients with corticobasal syndrome (CBS) and describe its relationship with clinical features in comparison to Parkinson's disease and healthy control subjects. In addition, we assessed prevalence and features of individuals with CBS and in vivo evidence of preserved nigral neuronal density. BACKGROUND Substantia nigra pars ...
متن کاملDopamine Transporter imaging with Tc-99m TRODAT-1 SPECT in Parkinson’s disease and its correlation with clinical disease severity
Objective(s): To evaluate the role of Tc-99m TRODAT-1 Single Photon Emission Computed Tomography (SPECT) in Parkinson’s Disease (PD) by assessing the correlation of clinical disease severity, disease duration and age at onset of disease with specific uptake ratio of Tc-99m TRODAT-1 in striatum.Methods: The study included 63 patients in age range of 40-72 years with clinical diagnosis of PD and ...
