The dopamine receptor D4 is a dopamine D2-like G protein-coupled receptor encoded by the DRD4 gene on chromosome 11 at 11p15.5. [5]

Contents

The structure of DRD4 was recently reported in complex with the antipsychotic drug nemonapride. [6]

As with other dopamine receptor subtypes, the D4 receptor is activated by the neurotransmitter dopamine. It is linked to many neurological and psychiatric conditions [7] including schizophrenia and bipolar disorder, [8] ADHD, [9] [10] addictive behaviors, [11] Parkinson's disease, [12] and eating disorders such as anorexia nervosa. [13] A weak association has been drawn between DRD4 and borderline personality disorder.

It is also a target for drugs which treat schizophrenia and Parkinson's disease. [14] The D4 receptor is considered to be D2-like in which the activated receptor inhibits the enzyme adenylate cyclase, thereby reducing the intracellular concentration of the second messenger cyclic AMP. [15]

Genetics

The human protein is coded by the DRD4 on chromosome 11 located in 11p15.5. [16]

There are slight variations (mutations/polymorphisms) in the human gene:

Mutations in this gene have been associated with various behavioral phenotypes, including autonomic nervous system dysfunction, attention deficit/hyperactivity disorder, [19] schizophrenia [20] and the personality trait of novelty seeking. [21]

48-base pair VNTR

The 48-base pair variable number tandem repeat (VNTR) in exon 3 range from 2 to 11 repeats. [16] Dopamine is more potent at the D4 receptor with 2 allelic repeat or 7 allelic repeats than the variant with 4 allelic repeats. [22]

DRD4-7R, the 7-repeat (7R) variant of DRD4 (DRD4 7-repeat polymorphism), has been linked to a susceptibility for developing ADHD in several meta-analyses and other psychological traits and disorders. [23] [24] Adults and children with the DRD4 7-repeat polymorphism show variations in auditory-evoked gamma oscillations, which may be related to attention processing. [25] [26]

The frequency of the alleles varies greatly between populations, e.g., the 7-repeat version has high incidence in America and low in Asia. [27] "Long" versions of polymorphisms are the alleles with 6 to 10 repeats. 7R appears to react less strongly to dopamine molecules. [28]

The 48-base pair VNTR has been the subject of much speculation about its evolution and role in human behaviors cross-culturally. The 7R allele appears to have been selected for about 40,000 years ago. [27] In 1999 Chen and colleagues [29] observed that populations who migrated farther in the past 30,000 to 1,000 years ago had a higher frequency of 7R/long alleles. They also showed that nomadic populations had higher frequencies of 7R alleles than sedentary ones. More recently it was observed that the health status of nomadic Ariaal men was higher if they had 7R alleles. However, in recently sedentary (non-nomadic) Ariaal those with 7R alleles seemed to have slightly deteriorated health. [30]

Novelty seeking

Despite early findings of an association between the DRD4 48bp VNTR and novelty seeking (a normal characteristic of exploratory and excitable people), [31] [32] a 2008 meta-analysis compared 36 published studies of novelty seeking and the polymorphism and found no effect. Results are consistent with novelty-seeking behavior being a complex trait associated with many genes, and the variance attributable to DRD4 by itself being very small. The meta-analysis of 11 studies did find that another polymorphism in the gene, the -521C/T, showed an association with novelty seeking. [21] While human results are not strong, research in animals has suggested stronger associations [33] [34] [35] [36] [37] [38] and new evidence suggests that human encroachment may exert selection pressure in favor of DRD4 variants associated with novelty seeking. [39] [ clarification needed ]

Cognition

Several studies have shown that agonists that activate the D4 receptor increase working memory performance and fear acquisition in monkeys and rodents according to a U-shaped dose response curve. [40] [41] [42] However, antagonists of the D4 receptor reverse stress-induced or drug-induced working memory deficits. [43] [44] Gamma oscillations, which may be correlated with cognitive processing, can be increased by D4R agonists, but are not significantly reduced by D4R antagonists. [45] [46] [47]

Cognitive development

Several studies have suggested that parenting may affect the cognitive development of children with the 7-repeat allele of DRD4. [39] Parenting that has maternal sensitivity, mindfulness, and autonomy–support at 15 months was found to alter children's executive functions at 18 to 20 months. [39] Children with poorer quality parenting were more impulsive and sensation seeking than those with higher quality parenting. [39] Higher quality parenting was associated with better executive control in 4-year-olds. [39]

Dopamine receptors are a class of G protein-coupled receptors that are prominent in the vertebrate central nervous system (CNS). Dopamine receptors activate different effectors through not only G-protein coupling, but also signaling through different protein interactions. The neurotransmitter dopamine is the primary endogenous ligand for dopamine receptors.

The hunter versus farmer hypothesis is a proposed explanation of the nature of attention-deficit hyperactivity disorder (ADHD) first suggested by radio host Thom Hartmann in his book Attention Deficit Disorder: A Different Perception. This hypothesis proposes that ADHD represents a lack of adaptation of members of hunter-gatherer societies to their transformation into farming societies. Hartmann developed the idea first as a mental model after his own son was diagnosed with ADHD, stating, "It's not hard science, and was never intended to be."

Histamine H<sub>3</sub> receptor Mammalian protein found in Homo sapiens

Histamine H3 receptors are expressed in the central nervous system and to a lesser extent the peripheral nervous system, where they act as autoreceptors in presynaptic histaminergic neurons and control histamine turnover by feedback inhibition of histamine synthesis and release. The H3 receptor has also been shown to presynaptically inhibit the release of a number of other neurotransmitters (i.e. it acts as an inhibitory heteroreceptor) including, but probably not limited to dopamine, GABA, acetylcholine, noradrenaline, histamine and serotonin.

<span class="mw-page-title-main">WAY-100635</span> Chemical compound

WAY-100635 is a piperazine drug and research chemical widely used in scientific studies. It was originally believed to act as a selective 5-HT1A receptor antagonist, but subsequent research showed that it also acts as potent full agonist at the D4 receptor. It is sometimes referred to as a silent antagonist at the former receptor. It is closely related to WAY-100135.

<span class="mw-page-title-main">A-412997</span> Chemical compound

A-412,997 is a drug which acts as a dopamine agonist that is used in scientific research. It is the first drug developed that is a highly selective agonist for the D4 subtype, with significantly improved selectivity over older D4-preferring compounds such as PD-168,077 and CP-226,269. In animal tests it improved cognitive performance in rats to a similar extent as methylphenidate, but without producing place preference or other signs of abuse liability. Also unlike other dopamine agonists, selective D4 agonists do not cause side effects such as sedation and nausea, and so might have advantages over older dopamine agonist drugs.

<span class="mw-page-title-main">WAY-100135</span> Chemical compound

WAY-100135 is a serotonergic drug of the phenylpiperazine family which is used in scientific research. It acts as potent 5-HT1A receptor antagonist, and was originally believed to be highly selective, but further studies have demonstrated that it also acts as a partial agonist of the 5-HT1D receptor (pKi = 7.58; virtually the same affinity for 5-HT1A), and to a much lesser extent, of the 5-HT1B receptor (pKi = 5.82). These findings may have prompted the development of the related compound WAY-100635, another purportedly selective and even more potent 5-HT1A antagonist, which was synthesized shortly thereafter. However, WAY-100635 turned out to be non-selective as well, having been shown to act additionally as a potent D4 receptor agonist later on.

1-(2-Pyrimidinyl)piperazine (1-PP, 1-PmP) is a chemical compound and piperazine derivative. It is known to act as an antagonist of the α2-adrenergic receptor (Ki = 7.3–40 nM) and, to a much lesser extent, as a partial agonist of the 5-HT1A receptor (Ki = 414 nM; Emax = 54%). It has negligible affinity for the dopamine D2, D3, and D4 receptors (Ki > 10,000 nM) and does not appear to have significant affinity for the α1-adrenergic receptors. Its crystal structure has been determined.

Roxindole (EMD-49,980) is a dopaminergic and serotonergic drug which was originally developed by Merck KGaA for the treatment of schizophrenia. In clinical trials its antipsychotic efficacy was only modest but it was unexpectedly found to produce potent and rapid antidepressant and anxiolytic effects. As a result, roxindole was further researched for the treatment of depression instead. It has also been investigated as a therapy for Parkinson's disease and prolactinoma.

<span class="mw-page-title-main">Sonepiprazole</span> Chemical compound

Sonepiprazole (U-101,387, PNU-101,387-G) is a drug of the phenylpiperazine class which acts as a highly selective D4 receptor antagonist. In animals, unlike D2 receptor antagonists like haloperidol, sonepiprazole does not block the behavioral effects of amphetamine or apomorphine, does not alter spontaneous locomotor activity on its own, and lacks extrapyramidal and neuroendocrine effects. However, it does reverse the prepulse inhibition deficits induced by apomorphine, and has also been shown to enhance cortical activity and inhibit stress-induced cognitive impairment. As a result, it was investigated as an antipsychotic for the treatment of schizophrenia in a placebo-controlled clinical trial, but in contrast to its comparator olanzapine no benefits were found and it was not researched further for this indication.
