Vesicular glutamate transporter VGLUT2 expression emerges in substantia nigra dopamine neurons in mouse models of parkinsonism in the absence of neurodegeneration

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 9, Page 2123-2138, May 2026.
Abstract Background and Purpose Subsets of midbrain dopamine (DA) neurons express the vesicular glutamate transporter VGLUT2 and can release the excitatory neurotransmitter glutamate. VGLUT2+ DA neurons of the substantia nigra pars compacta (SNc) were shown to be more resistant to neurodegeneration in animal models of Parkinson's disease (PD ...

Group II Metabotropic Glutamate Receptors: Role in Pain Mechanisms and Pain Modulation

open access: yesFrontiers in Molecular Neuroscience, 2018
Glutamate is the main excitatory neurotransmitter in the nervous system and plays a critical role in nociceptive processing and pain modulation.

An expanding range of targets for kynurenine metabolites of tryptophan [PDF]

open access: yes, 2013
The kynurenine pathway of tryptophan metabolism accounts for most of the tryptophan that is not committed to protein synthesis and includes compounds active in the nervous and immune systems.

TRP canonical 4 and/or 5 channel inhibition reduces aversion‐ and increases reward‐responding in chronically stressed mice

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 9, Page 2139-2165, May 2026.
Abstract Background and Purpose Pharmacological inhibition of TRPC4 and/or TRPC5 channels reduces Pavlovian aversion memory in stressed mice and reduces amygdala reactivity to aversion in humans with depression. The aims of this mouse study were to improve understanding of these anxiolytic processes, determine whether there are corrective effects on ...

Clozapine Normalizes a Glutamatergic Transmission Abnormality Induced by an Impaired NMDA Receptor in the Thalamocortical Pathway via the Activation of a Group III Metabotropic Glutamate Receptor

open access: yesBiomolecules, 2019
Pharmacological mechanisms of gold-standard antipsychotics against treatment-refractory schizophrenia, such as clozapine (CLZ), remain unclear. We aimed to explore the mechanisms of CLZ by investigating the effects of MK801 and CLZ on tripartite synaptic

Structural Mechanism of an Efficacy Photoswitch Targeting the β2‐adrenergic Receptor

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 18, 27 April 2026.
Time‐resolved structures from x‐ray free‐electron laser measurements combined with cellular assays demonstrate how the photoswitchable β‐blocker photoazolol‐1 acts as an efficacy switch of β2‐adrenergic receptor function. Light‐induced ligand repositioning shifts activity from inverse agonism toward neutral antagonism by altering local helical ...

Metabotropic Glutamate Receptor Activation in Cerebelar Purkinje Cells as Substrate for Adaptive Timing of the Classicaly Conditioned Eye Blink Response [PDF]

open access: yes, 1995
To understand how the cerebellum adaptively times the classically conditioned nictitating membrane response (NMR), a model of the metabotropic glutamate receptor (mGluR) second messenger system in cerebellar Purkinje cells is constructed.

Glycine Potentiates AMPA Receptor Function through Metabotropic Activation of GluN2A-containing NMDA Receptors

open access: yesFrontiers in Molecular Neuroscience, 2016
NMDA receptors are Ca2+-permeable ion channels. The activation of NMDA receptors requires agonist glutamate and co-agonist glycine. Recent evidence indicates that NMDA receptor also has metabotropic function.

Plasticity of GABA(B) receptor-mediated heterosynaptic interactions at mossy fibers after status epilepticus [PDF]

open access: yes, 2003
Several neurotransmitters, including GABA acting at presynaptic GABAB receptors, modulate glutamate release at synapses between hippocampal mossy fibers and CA3 pyramidal neurons.
