Such an injection of energy is provided by agonist collision. In der Gruppe der ionotropen Glutamatrezeptoren unterscheidet man drei Typen, die sich hinsichtlich ihres Aufbaus sowie der Bindungs-, Aktiverungs- und Leistungseigenschaften unterscheiden. Die Bezeichnung leitet sich nach der Präferenz für verschiedene Glutamat-Agonisten her. 2.1.1 AMPA-Rezeptoren An agonist of this group of receptors, at a dose that was without effects on spontaneous activity and corticolimbic dopamine neurotransmission, attenuated the disruptive effects of phencyclidine on working memory, stereotypy, locomotion, and cortical glutamate efflux. This behavioral reversal occurred in spite of sustained dopamine hyperactivity. Ionotropic glutamate receptors (iGluRs) mediate most excitatory neurotransmission in the central nervous system and function by opening their ion channel in response to binding of agonist glutamate.

Glutamate receptor agonist

N-Methyl-D-aspartic acid (NMDA) plays a crucial role in release of luteinizing hormone and PRL (prolactin) in the pituitary gland and GnRH (gonadotropin releasing hormone) in the hypothalamus. G-protein-coupled receptor kinases (GRKs) are key modulators of G-protein-coupled receptor (GPCR) signaling. They constitute a family of seven mammalian serine-threonine protein kinases that phosphorylate agonist-bound receptor. GRKs-mediated receptor phosphorylation rapidly initiates profound impairment of receptor signaling and desensitization. GABA B receptors are involved in behavioral actions of ethanol, gamma-hydroxybutyric acid (GHB), and possibly in pain. Recent research suggests that these receptors may play an important developmental role.
