dopaminergic receptor

dopaminergic receptor

a protein on the surfaces of certain cells that binds specifically to the neurotransmitter dopamine. Such receptors on vascular epithelial cells, when stimulated by dopamine, cause the renal mesenteric, coronary, and cerebral arteries to dilate and the flow of blood to increase.

For instance, the dopaminergic receptor genes DRDla and DRD2 were differentially expressed 2 days after reperfusion after stroke in mice (Sieber et al.
4) Later, further gene variants of dopamine receptors, transporter or other regulator genes were discovered related to low dopaminergic receptor function (5) and low dopamine release.
Hence, the presence of the A1 allele of the D2 dopaminergic receptor gene polymorphism has been indicated as a possible factor for the emergence of certain movement disorders such as dystonia.

1] activity antagonists that reverted the effects of d-amphetamine on the quarter life, it could be thought that this subtype of dopaminergic receptor could have a greater implication in the perception of time.
Ejaculatory disturbances, diminished sexual desire, and erectile dysfunction associated with risperidone have been reported and several mechanisms including central dopaminergic receptor blockade, a-adrenergic antagonism, and prolactin elevation have been proposed (17,18,19,20).
If confirmed it will suggest that NAAT "normalizes" brain abnormalities associated with drug dependence (alcohol, heroin and psychostimulants) induced by dopaminergic deficiency by acting as a dopaminergic receptor agonist during protracted abstinence in polydrug abusers.

Moreover, pimavanserin has no appreciable affinity for dopaminergic receptors, and therefore does not induce motor adverse effects.
It also has a high affinity for dopaminergic receptors, mainly D2, D3, and D4; muscarinic M1-5; (alpha-1) [alpha]-1 adrenergic; and histaminergic H1 receptorsin vitro.
