Glutamate is the major excitatory neurotransmitter in the mammalian CNS. Glutamate mediates its action by binding to both ionotropic and metabotropic receptors. The glutamate receptors that are located at post synaptic terminals, mediate depolarisation and Ca2+ entry into the cells to trigger excitotoxicity, on excessive exposure to glutamate.

Glutamate (the conjugate base of glutamic acid) is abundant in the human body, but particularly in the nervous system and especially prominent in the human brain where it is th Glutamate receptors. The antagonists of ionotropic glutamate receptors, including antagonists of AMPA (2,3-benzodiazepine), kainate (LY382884, LY466195 and NS3763), AMPA/KA (NBQX and CNQX) and NMDA (ketamine, MK-801, dichlorokynurenic acid, L-701,324 and GV196771), decrease nociceptive transmission (Bleakmanetal.2006),butbecauseoftheirside Glutamate receptors are the predominant excitatory neurotransmitter receptors in the mammalian brain and are activated in a variety of normal neurophysiologic processes. These receptors are heteromeric protein complexes composed of multiple subunits, arranged to form ligand-gated ion channels. Kontrollera 'glutamate receptor' översättningar till svenska.

• L- Glutamate is widely distributed excitatory neurotransmitter in the CNS, where its concentration is much higher than in other tissues. Description.

Glutamate receptors are the most abundant type of excitatory neurotransmitter receptors in the mammalian forebrain. Glutamate receptors are responsible for the excitatory drive in neuronal networks, and are uniquely involved in activating downstream signaling cascades required for synaptic plasticity, learning, and memory.
