Application

L-741,626 has been used as selective dopamine (D2) receptor antagonist to study its effects on the uptake of dopamine in human embryonic kidney 293 (HEK293) cells. It has also been used as a D2 receptor antagonist to study its effects on thyrotropin-releasing hormone (TRH) induced prolactin release.

Dopamine can modulate and excite spinal locomotor networks, affect afferent transmission and increase motoneuronal excitability. One of the mechanisms whereby dopamine increases motoneuronal excitability is to potentiate AMPA channel-mediated glutamatergic transmission onto motoneurons. However, it is not known which dopaminergic

Low testosterone (T) in men, especially its free fraction, has been associated with loss of energy. In accordance, orchidectomy (ORX) in rodents results in decreased physical activity. Still, the mechanisms through which T stimulates activity remain mostly obscure. Here, we

In the retina, activation of dopamine receptors, particularly the D2-like family (D2, D3, D4 receptor subtypes), with quinpirole suppresses the light sensitive cAMP pool and inhibits melatonin synthesis in photoreceptor cells. We have characterised rat retinal D4 receptors using the

The dopamine D(3) receptor agonist PD 128907 decreased body temperature in the rat. The selective dopamine D(3) and D(4) receptor antagonists, A-437203 and L-745,870, respectively, did not prevent this effect. In contrast, PD 128907-induced hypothermia was antagonized by SCH 23390

The role of D(3) receptors in the antiparkinsonian actions of l-DOPA and l-DOPA-induced dyskinesia (LID) remains unclear. The D(3) receptor partial agonist BP897 attenuates LID in primates without affecting the antiparkinsonian actions of l-DOPA, suggesting that "normalization" of D(3) activity
