Olfactory receptor neurons express D2 dopamine receptors

The Journal of Comparative Neurology, 1999
The role of the dopamine (DA) in the olfactory bulb (OB) was explored by determining which of the potential target cells express dopamine receptors (DARs). Previously, it was reported that D2-like DAR (D2, D3, and D4 subtypes) radioligand binding is restricted to the outer layers of the OB.

D2 dopamine receptor gene and alcoholism

Journal of Psychiatric Research, 1993
An allelic association of the TAQ I A1 D2 dopamine receptor gene polymorphism has been found in homogeneous populations of alcoholics from France.

Solubilized dopamine/neuroleptic receptors (D2-type)

Progress in Neuro-Psychopharmacology, 1981
Abstract 1. 1. Dopamine (D 2 -type) receptors were solubilized from striatum of three species (human, canine, calf) using digitonin. 2. 2. The receptors were labeled with 3 H-spiperone and assayed by Sephadex G-50 columns or polyethylene glycol precipitation. 3. 3. The soluble receptors from canine and human tissue had similar K d 's and

Cerebellar dopamine D2 receptors regulate social behaviors

Nature Neuroscience, 2022
The cerebellum, a primary brain structure involved in the control of sensorimotor tasks, also contributes to higher cognitive functions including reward, emotion and social interaction. Although the regulation of these behaviors has been largely ascribed to the monoaminergic system in limbic regions, the contribution of cerebellar dopamine signaling in

The Dopamine D2 Receptor

1992
Dopamine is the dominant catecholamine neurotransmitter in the mammalian brain. It is found throughout the entire central nervous system, but is predominant in the nigrostriatal, mesolimbic, and tuberoinfundibular tracts (Creese et al., 1983). Dopamine exerts its effects through binding to two types of receptor, the D1 and D2 receptors (Kebabian and ...

Dopamine D2 Receptor Dimers and Receptor-Blocking Peptides

Biochemical and Biophysical Research Communications, 1996
Dopamine D2 receptors exist as dimers in whole cell lysate, crude membranes prepared from human caudate, and following solubilization and immunoprecipitation of the receptor from these tissues. Photoaffinity labelling experiments confirmed that D2 receptors exist either as monomers that are selective targets for spiperone or as dimers that are targets ...

D2 dopamine receptor involvement in spinal dopamine-produced antinociception

Life Sciences, 1992
Experiments were performed on 79 lightly pentobarbital-anesthetized rats. Rats displayed a dose-dependent increase in tail-flick latencies following the injection of dopamine (DA) into the lumbar subarachnoid space through an intrathecal tube. Sulpiride, a D2-subtype receptor antagonist, antagonized the DA-induced analgesia (antinociceptive) effect ...

The Physiological Role of Dopamine D2 Receptors

1997
Publisher Summary Interest lies in the study of the physiological activity of D2 receptors that are abundantly expressed in the striatum, substantia nigra, and hypophysis. Two isoforms of this receptor have been described that differ by their coupling characteristics to G-proteins in vitro.

Dopamine D2 Receptor and Tourette's Syndrome

Archives of Neurology, 1995
I was pleased to see the study by Gelernter et al 1 concerning the role of the dopamine D 2 receptor ( DRD2 ) gene in Tourette syndrome (TS) because the authors so nicely verified our previous studies demonstrating a role the DRD2 gene in TS and because they illustrated some of the issues concerning association vs linkage studies in neuropsychiatric ...

D2 dopamine receptor localization on striatonigral neurons

Neuroscience Letters, 1992
Two major pharmacological classes of dopamine receptors exist in the central nervous system. These receptors have been designated as D1 or D2 based upon their differing pharmacology and influence on the cyclic AMP second messenger system. Different genes for the D1 and D2 dopamine receptors have been isolated and are found to be expressed in high ...
