Simulation of postsynaptic glutamate receptors reveals critical features of glutamatergic transmission. [PDF]
Activation of several subtypes of glutamate receptors contributes to changes in postsynaptic calcium concentration at hippocampal synapses, resulting in various types of changes in synaptic strength.

Positive allosteric modulators of the a-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor [PDF]
L-glutamate is the major excitatory neurotransmitter in the mammalian central nervous system (CNS) and plays a fundamental role in the control of motor function, cognition and mood.

Background Drosophila discs-large (DLG) is the sole representative of a large class of mammalian MAGUKs, including human DLG, SAP 97, SAP102, and PSD-95. MAGUKs are thought to be critical for postsynaptic assembly at glutamatergic synapses.

Chronic glutamate toxicity in neurodegenerative diseases-what is the evidence?
Together with aspartate, glutamate is the major excitatory neurotransmitter in the brain. Glutamate binds and activates both ligand-gated ion channels (ionotropic glutamate receptors) and a class of G-protein coupled receptors (metabotropic glutamate ...

AMPA and Kainate Receptors Each Mediate Excitotoxicity in Oligodendroglial Cultures
Recent studies indicate that oligodendrocytes are vulnerable to excitotoxic insults mediated by glutamate receptors. The present study was carried out to characterize the type of glutamate receptors triggering cell death in optic nerve oligodendrocyte ...

Phased Treatment Strategies for Cerebral Ischemia Based on Glutamate Receptors
Extracellular glutamate accumulation following cerebral ischemia leads to overactivation of glutamate receptors, thereby resulting in intracellular Ca2+ overload and excitotoxic neuronal injury. Multiple attempts have been made to counteract such effects

Inhibition of the mitochondrial pyruvate carrier protects from excitotoxic neuronal death. [PDF]
Glutamate is the dominant excitatory neurotransmitter in the brain, but under conditions of metabolic stress it can accumulate to excitotoxic levels.

Modulation of glutamate transport and receptor binding by glutamate receptor antagonists in EAE rat brain. [PDF]
The etiology of multiple sclerosis (MS) is currently unknown. However, one potential mechanism involved in the disease may be excitotoxicity. The elevation of glutamate in cerebrospinal fluid, as well as changes in the expression of glutamate receptors ...

mGluR5 antagonism inhibits cocaine reinforcement and relapse by elevation of extracellular glutamate in the nucleus accumbens via a CB1 receptor mechanism. [PDF]
Metabotropic glutamate receptor 5 (mGluR5) antagonism inhibits cocaine self-administration and reinstatement of drug-seeking behavior. However, the cellular and molecular mechanisms underlying this action are poorly understood.

Glutamate receptor pores [PDF]
AbstractGlutamate receptors are ligand‐gated ion channels that mediate fast excitatory synaptic transmission throughout the central nervous system. Functional receptors are homo‐ or heteromeric tetramers with each subunit contributing a re‐entrant pore loop that dips into the membrane from the cytoplasmic side. The pore loops form a narrow constriction
