Unchanged type 1 metabotropic glutamate receptor availability in patients with Alzheimer's disease: A study using 11C-ITMM positron emission tomography

NeuroImage: Clinical, 2019
Imaging of type 1 metabotropic glutamate receptor (mGluR1) has recently become possible using positron emission tomography (PET). To date, little evidence exists on the role of mGluR1 in the pathophysiology of Alzheimer's disease (AD).

Troriluzole attenuates opioid intake, reinforcing efficacy, seeking behaviours, physical dependence and antinociceptive tolerance in rats

British Journal of Pharmacology, EarlyView.
Background and Purpose Riluzole, approved for amyotrophic lateral sclerosis (ALS), has a glutamate‐modulating profile favourable for mitigating opioid addiction. It reduces neuronal glutamate release and enhances glutamate reuptake, offering advantages over agents that only increase glutamate reuptake.

Interplay between metabotropic glutamate type 4 and adenosine type 1 receptors modulate synaptic transmission in the cerebellar cortex

Frontiers in Pharmacology
The synapses between parallel fibers and Purkinje cells play a pivotal role in cerebellar function. They are intricately governed by a variety of presynaptic receptors, notably by type 4 metabotropic glutamate (mGlu4) receptors and type 1 adenosine (A1 ...

The Neurotransmitter Glutamate Reduces Axonal Responsiveness to Multiple Repellents through the Activation of Metabotropic Glutamate Receptor 1

Journal of Neuroscience, 2004
Glutamate is the major excitatory neurotransmitter in the mammalian CNS. Here, we propose a new role for this neurotransmitter in the developing nervous system.

WONOEP XVII appraisal: Targeting network excitability beyond the synapse ‐Neurotransmitter, ionic, and electro ‐diffusions

Epilepsia, EarlyView.
Abstract Epilepsy affects approximately 1% of the population worldwide, and although medications are effective in the majority of cases, seizures persist in approximately 30% of patients. Despite the effort to develop new antiseizure drugs, the rate of pharmacoresistance in patients has not diminished over the past 3 decades. There is thus a real unmet

Long-term activation of group I metabotropic glutamate receptors increases functional TRPV1-expressing neurons in mouse dorsal root ganglia

Frontiers in Cellular Neuroscience, 2016
Damaged tissues release glutamate and other chemical mediators for several hours. These chemical mediators contribute to modulation of pruritus and pain.

Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia

Journal of Anatomy, Volume 246, Issue 4, Page 505-516, April 2025.
Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...

Optimization of photobiomodulation therapy for spinal cord injury: A review

Photochemistry and Photobiology, EarlyView.
Photobiomodulation (PBM) therapy in the red and near‐infrared range can significantly modulate the secondary injury response and promote the reparative and regenerative potential of neural tissue after spinal cord injury (SCI). At present, due to the nature of delivery methods, the most effective dose and irradiance at the injury site to optimize ...

Metabotropic glutamate receptor 1 (mGluR1) and 5 (mGluR5) regulate late phases of LTP and LTD in the hippocampal CA1 region in vitro

European Journal of Neuroscience, 2008
The group I metabotropic glutamate receptors, mGluR1 and mGluR5, exhibit differences in their regulation of synaptic plasticity, suggesting that these receptors may subserve separate functional roles in information storage.

Astrocytes: Orchestrators of brain gas exchange and oxygen homeostasis

The Journal of Physiology, EarlyView.
Abstract figure legend Oxygen and carbon dioxide enter the body via breathing; in the brain astrocytes play a key role balancing oxygen delivery with carbon dioxide removal. Abstract If we consider neurons like muscles during exercise, the demand for oxygen (O2) and carbon dioxide (CO2) elimination is constantly changing.
