Alpha-2 adrenergic receptor - Wikipedia
The alpha-2 (α 2) adrenergic receptor (or adrenoceptor) is a G protein-coupled receptor (GPCR) associated with the G i heterotrimeric G-protein.It consists of three highly homologous subtypes, including α 2A-, α 2B-, and α 2C-adrenergic.Some species other than humans express a fourth α 2D-adrenergic receptor as well. Catecholamines like norepinephrine (noradrenaline) and epinephrine ...

In this review, we focus on molecular targets of relevance to noradrenaline (NA). In order to contribute to the search for new selective antiepileptic drugs, we analyze noradrenergic modulation of spike-wave activity, discuss the separation of sedative and pro-absence effects of alpha2 AR agonists and formulate testable hypotheses about the role of alpha2 AR subtypes and their interaction with ...

Basic properties of Alpha 2 Adrenoceptors . The noradrenergic system uses norepinephrine (NE) as its main chemical messenger and serves multiple brain functions, including arousal, attention, mood, learning, memory and stress response [].Noradrenergic neurons are localized in brainstem nuclei such as the locus ceruleus(LC), and noradrenergic axons project diffusely to almost every part of the ...
Alpha2 adrenergic agonists for attention deficit hyperactivity disorder ...
Alpha2 agonists are medications that stimulate alpha2 adrenergic receptors in various parts of the nervous system, particularly the prefrontal cortex. Of these, clonidine and guanfacine have been used specifically in the treatment of ADHD. They can be administered either orally or transdermally (absorbed through the skin).
Alpha 1 and Alpha 2 are both types of adrenergic receptors in the body that react to various neurotransmitters such as adrenaline and noradrenaline. These neurotransmitters play important roles in regulating heart rate, blood pressure, metabolism, and other physiological functions. Alpha-1 receptors primarily work by causing constriction of ...
