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

Previous studies suggest that metabotropic glutamate 2/3 receptors are involved in psychiatric disorders.In this study, we examined the effects of the selective metabotropic glutamate 2/3 (mGlu2/3) receptor agonist MGS0028 on behavioral abnormalities in mice lacking the pituitary adenylate cyclase-activating polypeptide (PACAP), an experimental model of psychiatric disorders such as

Ionotropic glutamate receptors (iGluRs), such as N-methyl-d-aspartate (NMDA), amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), and kainate receptors, are ligand-gated ion channels that stimulate fast excitatory neurotransmission (Dingledine et al., 1999). In contrast, metabotropic glutamate receptors (mGluRs) are G-protein coupled receptors (GPCRs) that have been categorized into three groups based on their signal transduction pathways and pharmacological profiles. N-methyl-d-Aspartate (NMDA) receptors are a subtype of ionotropic glutamate receptors essential for synaptic plasticity and memory formation 1,2.Hyperactivity and hypofunction of NMDA receptors They belong to so called superfamily of nuclear receptors (other members of this class include vitamins A and D, estrogen thyroid and glucocorticoid receptors). There are 3 types of PPARs: PAR-a, PPAR-d, and PPAR-?. PPAR-γ activators (agonists) can effectively protect against GE, decrease brain inflammation and degeneration. Furthermore, they can “ reprogram” the immune response, stimulate metabolic and mitochondrial function, promote axon growth and make progenitor cells differentiate

Kainate receptors are members of the ionotropic class of glutamate receptors, which also includes NMDA and AMPA receptors. Composed of subunits GluK1-5, kainate receptors are found both pre- and post-synaptically and modulate both excitatory and inhibitory synaptic transmission. Glutamate receptor agonists are generally α-amino acids with one or more stereogenic centers due to strict requirements in the agonist binding pocket of the activated state of the receptor. By contrast, there are many examples of achiral competitive antagonists. Metabotropic glutamate receptors (mGluRs) play key roles in the modulation of both excitatory and inhibitory synapses in the brain.
