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.

(27,28) Although the alfa-2 adrenergic receptor is a known mechanism of controlling blood pressure by negative feedback on sympathetic neuronal fibers, this inhibitory effect of dexmedetomidine has a small effect on blood pressure (11,29).
INTUNIV is a non-stimulant, selective alpha-2A adrenergic receptor agonist that is being co-developed and commercialised by Shire and Shionogi under a licensing contract that was signed in 2011.
In contrast, in long-term treatment, TCAs induce adrenergic desensitization, and moreover, catecholamine depletion may further deteriorate response to sympathomimetics.[5] The less potent sympathomimetics may not be effective for the hypotension in long-term TCA treatment patients because the adrenergic receptors are desensitized and catecholamine storage is depleted.[15] The depletion of norepinephrine stores resulting from TCAs causes a peripheral adrenergic receptor blockade and they block the reuptake of norepinephrine and dopamine at presynaptic nerve terminals.[16] This predisposes chronic TCA users to lower blood pressures during induction of anesthesia.
Various epidemiological and clinical studies indicate that strong linkage exists between common allelic variants of the adrenergic receptor genes and weight gain as well as changes in body composition (Bea et al., 2010; Masuo et al., 2005a; Phares et al., 2004; Szendrei et al., 2016).
