Astrocytes Maintain Glutamate Homeostasis in the CNS by Controlling the Balance between Glutamate Uptake and Release

open access: yesCells, 2019
Glutamate is one of the most prevalent neurotransmitters released by excitatory neurons in the central nervous system (CNS); however, residual glutamate in the extracellular space is, potentially, neurotoxic.

Glutamate metabolism and recycling at the excitatory synapse in health and neurodegeneration

open access: yesNeuropharmacology, 2021
Glutamate is the primary excitatory neurotransmitter of the brain. Cellular homeostasis of glutamate is of paramount importance for normal brain function and relies on an intricate metabolic collaboration between neurons and astrocytes.

Metabotropic Glutamate Receptors Inhibit Microglial Glutamate Release [PDF]

open access: yesASN Neuro, 2012
Pro-inflammatory stimuli evoke an export of glutamate from microglia that is sufficient to contribute to excitotoxicity in neighbouring neurons. Since microglia also express various glutamate receptors themselves, we were interested in the potential ...

PKA drives an increase in AMPA receptor unitary conductance during LTP in the hippocampus

open access: yesNature Communications, 2021
Long-term potentiation at hippocampal CA1 synapses can be due to increasing the number and/or single-channel conductance of AMPA receptors. The authors show that PKA and CaMKII are necessary and together sufficient to increase single channel conductance,

The Role of Glutamate Receptors in Epilepsy

open access: yesBiomedicines, 2023
Glutamate is an essential excitatory neurotransmitter in the central nervous system, playing an indispensable role in neuronal development and memory formation. The dysregulation of glutamate receptors and the glutamatergic system is involved in numerous

Glutamate and reinstatement [PDF]

open access: yesCurrent Opinion in Pharmacology, 2009
The importance of glutamate in the reinstatement of cocaine-seeking behavior has been established. New molecular and neurochemical adaptations in the glutamatergic system which drive cocaine relapse have been identified, such as the ability of CB1 receptor stimulation to reduce basal glutamate levels and the involvement of the GluR1 receptor subunit in

The effect of antipsychotics on glutamate levels in the anterior cingulate cortex and clinical response: A 1H-MRS study in first-episode psychosis patients

open access: yesFrontiers in Psychiatry, 2022
IntroductionGlutamatergic dysfunction is implicated in the pathophysiology of schizophrenia. It is unclear whether glutamatergic dysfunction predicts response to treatment or if antipsychotic treatment influences glutamate levels.

Illuminating Relationships Between the Pre- and Post-synapse

open access: yesFrontiers in Neural Circuits, 2020
Excitatory synapses in the mammalian cortex are highly diverse, both in terms of their structure and function. However, relationships between synaptic features indicate they are highly coordinated entities.

Structural basis of subtype-selective competitive antagonism for GluN2C/2D-containing NMDA receptors

open access: yesNature Communications, 2020
Selectively inhibiting N-Methyl-D-aspartate receptors (NMDARs) containing the GluN2C/2D subunits has been challenging. Here, using electrophysiology and X-ray crystallography, authors show that compounds UBP791 and UBP1700 show over 40- and 50-fold ...

The glutamate story [PDF]

open access: yesBritish Journal of Pharmacology, 2006
Glutamatergic synaptic transmission in the mammalian central nervous system was slowly established over a period of some 20 years, dating from the 1950s. Realisation that glutamate and like amino acids (collectively known as excitatory amino acids (EAA)) mediated their excitatory actionsviamultiple receptors preceded establishment of these receptors as
