Genetic variants may modulate dopamine transporter (DAT) availability in the brain. A polymorphism within the intron 8 of the DAT1 gene was evaluated in 27 healthy men. No correlation between Int8 VNTR and either the inter-individual variability of the sleep architecture, or the DAT availability, as measured by single photon emission computed tomography (SPECT) and [(⁹⁹m)Tc]TRODAT-1 was observed.

3,4-methylenedioxymethamphetamine (MDMA; commonly referred to as "ecstasy" or "molly") is a substituted amphetamine drug that is used recreationally for its acute psychoactive effects, including euphoria and increased energy, as well as prosocial effects such as increased empathy and feelings of closeness with others. Acute adverse effects can include hyperthermia, dehydration, bruxism, and diaphoresis. Post-intoxication phenomena may include insomnia, anhedonia, anxiety, depression, and memory impairment, which can persist for days following drug cessation.

Oxidation of dopamine can cause various side effects, which ultimately leads to cell death and contributes to Parkinson's disease (PD). To counteract dopamine oxidation, newly synthesized dopamine is quickly transported into vesicles via vesicular monoamine transporter 2 (VMAT2) for storage. VMAT2 expression is reduced in patients with PD, and studies have shown increased accumulation of dopamine oxidation byproducts and α-synuclein in animals with low VMAT2 expression.

Autism spectrum disorder (ASD) is a complex developmental disorder characterized by several behavioral impairments, especially in socialization, communication, and the occurrence of stereotyped behaviors. In rats, prenatal exposure to valproic acid (VPA) induces autistic-like behaviors. Previous studies by our group have suggested that the autistic-like phenotype is possibly related to dopaminergic system modulation because tyrosine hydroxylase (TH) expression was affected.

Background And Purpose: We investigated the relationship between serotonergic and dopaminergic specific binding transporter ratios (SBRs) over 4 years in Parkinson's disease (PD) patients. We assessed serotonergic innervation's potential compensatory role for dopaminergic denervation, association with PD symptoms, and involvement in the development of levodopa-induced dyskinesia (LID).
Methods: SBRs of the midbrain and striatum were evaluated from [I-123] N-ω-fluoropropyl-2β-carbomethoxy-3β-(4-iodophenyl)nortropane SPECT images at baseline and after 4 years.

Article Synopsis
- Recent research indicates that a deficiency in the melanocortin 1 receptor (MC1R) is linked to neurodegeneration similar to Parkinson's disease in a specific brain region called the substantia nigra (SN).
- The study used techniques like in situ hybridization and immunohistochemistry to identify the location and characteristics of MC1R, finding it mostly in susceptible dopaminergic neurons and in a type of inhibitory neuron known as parvalbumin (PV)-positive neurons.
- The results show that MC1R is involved not only in the cell membrane but also in organelles like mitochondria, suggesting that it, along with a modulator called attractin (Atrn), plays an important role in
