re·cep·tor

 (rĭ-sĕp′tər)
n.
1. Physiology A specialized cell or group of nerve endings that responds to sensory stimuli.
2. Biochemistry A molecular structure or site on the surface or interior of a cell that binds with substances such as hormones, antigens, or neurotransmitters or is activated by events such as a change in the concentration of an ion.

receptor

(rɪˈsɛptə)
n
1. (Physiology) physiol a sensory nerve ending that changes specific stimuli into nerve impulses
2. any of various devices that receive information, signals, etc

re•cep•tor

(rɪˈsɛp tər)

n.
1. a protein molecule, usu. on the surface of a cell, that is capable of binding to a complementary molecule, as a hormone, antibody, or antigen.
2. a sensory nerve ending or sense organ that is sensitive to stimuli.

re·cep·tor

(rĭ-sĕp′tər)
1. A nerve ending specialized to sense or receive stimuli. Skin receptors respond to stimuli such as touch and pressure and signal the brain by activating portions of the nervous system. Receptors in the nose detect odors.
2. A cell structure or site that is capable of combining with a hormone, antigen, or other chemical substance.

The dopamine receptor D2 (DRD2) is a transmembrane protein which belongs to the class of G-protein-coupled receptors (also known as the seven-transmembrane domain receptors) [1].
Epigenetic modification resulted in the dopamine receptor gene being silenced: neurons carried fewer dopamine receptors, and signal transmission was reduced.
One variant of the dopamine receptor gene, called 7R, is particularly associated with impulsive, novelty-seeking behavior; perhaps early humans with this gene were more likely to migrate to new areas.
Dr Ma said, "Early detection is crucial for improving the survival rate of hard-to-treat cancers such as lung cancer, which is associated with dopamine receptor expression.
As the dose increases, lumateperone also serves as a mesolimbic and mesocortical dopamine receptor phosphoprotein modulator with dual properties, acting at the level of the dopamine D2 receptor both as a presynaptic partial agonist and a postsynaptic antagonist.

Although the pathophysiology of TD has not been completely elucidated, the most commonly accepted hypothesis is dopamine receptor hypersensitivity.

Dopamine receptor antagonists antagonized effects of dopamine by combining with dopamine receptor, such as phenothiazines sedative and antiemetic (metoclopramide, domperidone).
