Dopamine D4 receptors: curiouser and curiouser.
Identification of the D, receptor The D4 receptor was fit identified, using molecular biological techniques, from human’ and from rat2 and shown to be a member of the family of G protein-coupled dopamine receptors. It has substantial homology with Dz and DJ receptors (and is a member of the D,-like receptor subfamily) but its distribution and pharmacological properties are different from either...
متن کاملHomeostatic regulation of glutamatergic transmission by dopamine D4 receptors.
Alterations of synaptic transmission have been considered a core feature of mental disorders; thus, we examined the role of dopamine D(4) receptors, which is highly implicated in attention-deficit hyperactivity disorder and schizophrenia, in regulating synaptic functions of prefrontal cortex, a brain region critical for cognitive and emotional processes. We found that D(4) stimulation caused a ...
متن کاملDopamine, cognitive function, and gamma oscillations: role of D4 receptors
Cognitive deficits in individuals with schizophrenia (SCZ) are considered core symptoms of this disorder, and can manifest at the prodromal stage. Antipsychotics ameliorate positive symptoms but only modestly improve cognitive symptoms. The lack of treatments that improve cognitive abilities currently represents a major obstacle in developing more effective therapeutic strategies for this debil...
متن کاملNorepinephrine activates dopamine D4 receptors in the rat lateral habenula.
The lateral habenula (LHb) is involved in reward and aversion and is reciprocally connected with dopamine (DA)-containing brain regions, including the ventral tegmental area (VTA). We used a multidisciplinary approach to examine the properties of DA afferents to the LHb in the rat. We find that >90% of VTA tyrosine hydroxylase (TH) neurons projecting to the LHb lack vesicular monoamine transpor...
متن کاملThe Dopamine D4 Receptor
The observation that receptors which mediate their signals through heterotrimeric guanosine triphosphate (GTP)-binding proteins (Gproteins) share a considerable amount of sequence similarity has resulted in the rapid molecular characterization of this receptor superfamily. Moreover, it became clear that several receptor families consisted of more receptor subtypes than originally anticipated fr...
