Gray-matter volume, midbrain dopamine D2/D3 receptors and drug craving in methamphetamine users. [PDF]

Molecular Psychiatry, 2015
Dysfunction of the mesocorticolimbic system has a critical role in clinical features of addiction. Despite evidence suggesting that midbrain dopamine receptors influence amphetamine-induced dopamine release and that dopamine is involved in ...

Cocaine inhibits dopamine D2 receptor signaling via sigma-1-D2 receptor heteromers. [PDF]

PLoS ONE, 2013
Under normal conditions the brain maintains a delicate balance between inputs of reward seeking controlled by neurons containing the D1-like family of dopamine receptors and inputs of aversion coming from neurons containing the D2-like family of dopamine

Dopamine signaling in food addiction: role of dopamine D2 receptors

BMB Reports, 2013
Dopamine (DA) regulates emotional and motivational behavior through the mesolimbic dopaminergic pathway. Changes in DA signaling in mesolimbic neurotransmission are widely believed to modify reward-related behaviors and are therefore closely associated with drug addiction.

Dopamine D2 receptor upregulation in dorsal striatum in the LRRK2-R1441C rat model of early Parkinson’s disease revealed by in vivo PET imaging [PDF]

Scientific Reports
We conducted PET imaging with [18F]FDOPA and dopamine D2/3 receptor ligand [18F]fallypride in aged transgenic rats carrying human pathogenic LRRK2 R1441C or G2019S mutations.

Dopamine, the dopamine D2 receptor and pituitary tumours [PDF]

Clinical Endocrinology, 1991
Dopamine plays an important role in the hypothalamic-pituitary axis where its major effects are to inhibit pituitary hormone secretion and cell division. Chronic dopamine deficiency has been postulated as a cause of pituitary tumour formation and several lines of evidence exist to suggest that a functional deficiency may develop as a result of ...

Pharmacological blockade of dopamine D1- or D2-receptor in the prefrontal cortex induces attentional impairment in the object-based attention test through different neuronal circuits in mice

Molecular Brain, 2021
Dopamine is a key neurotransmitter that regulates attention through dopamine D1 and D2-receptors in the prefrontal cortex (PFC). We previously developed an object-based attention test (OBAT) to evaluate attention in mice.

Dystonia: sparse synapses for D2 receptors in striatum of a DYT1 knock-out mouse model [PDF]

, 2020
Dystonia pathophysiology has been partly linked to downregulation and dysfunction of dopamine D2 receptors in striatum. We aimed to investigate the possible morpho-structural correlates of D2 receptor downregulation in the striatum of a DYT1 Tor1a mouse ...

D2-Like Receptors Mediate Dopamine-Inhibited Insulin Secretion via Ion Channels in Rat Pancreatic β-Cells

Frontiers in Endocrinology, 2020
Dopamine (DA) has a vital role in the central nervous system and also modulates lipid and glucose metabolism. The present study aimed to investigate the effect of dopamine on insulin secretion and the underlying mechanisms in rat pancreatic β-cells. Data

Dysregulation of dopamine neurotransmission in the nucleus accumbens in immobilization-induced hypersensitivity

Frontiers in Pharmacology, 2022
Cast immobilization causes sensory hypersensitivity, which is also a symptom of neuropathic pain and chronic pain. However, the mechanisms underlying immobilization-induced hypersensitivity remain unclear.

D2 dopamine receptor gene and obesity [PDF]

International Journal of Eating Disorders, 1994
The prevalence of Taql A D2 dopamine receptor (DRD2) alleles was determined in 73 obese women and men. In this sample with a mean body mass index of 35.1, the A1 (minor) allele of the DRD2 gene was present in 45.2% of these nonalcohol, nondrug abusing subjects. The DRD2 A1 allele was not associated with a number of cardiovascular risk factors examined,
