A comprehensive review on adaptive plasticity and recovery mechanisms post‐acquired brain injury

Neuroprotection, EarlyView.
This figure illustrates the dynamic process of neurogenesis following brain injury, focusing on the roles of neural stem and progenitor cells at the injury site. Key mechanisms include axonal sprouting, synaptogenesis, dendritic remodeling, and brain‐derived neurotrophic factor signaling via TrkB receptors.

Astrocytes Control Neuronal Excitability in the Nucleus Accumbens

The Scientific World Journal, 2007
Though accumulating evidence shows that the metabotropic glutamate receptor 5 (mGluR5) mediates some of the actions of extracellular glutamate after cocaine use, the cellular events underlying this action are poorly understood.

Reduced Expression of Cerebral Metabotropic Glutamate Receptor Subtype 5 in Men with Fragile X Syndrome

Brain Sciences, 2020
Glutamatergic receptor expression is mostly unknown in adults with fragile X syndrome (FXS). Favorable behavioral effects of negative allosteric modulators (NAMs) of the metabotropic glutamate receptor subtype 5 (mGluR5) in fmr1 knockout (KO) mouse ...

Memantine Administration Enhances Glutamatergic and GABAergic Pathways in the Human Hippocampus of Alzheimer's Disease Patients

PROTEOMICS, EarlyView.
ABSTRACT One of the traditional treatments in Alzheimer's disease (AD) is administration of memantine, the NMDA receptor antagonist. However, the molecular mechanism of the complex memantine action and the impact on the hippocampal proteome in humans is unknown.

Calcium Signaling Pathways Involved in Long-Term Potentiation at Excitatory Synapses on Parvalbumin Positive Fast-Spiking GABAergic Neurons in the Mouse Visual Cortex [PDF]

Cell Journal, 2009
Objective: Recently, we reported the presence of metabotropic glutamate receptor type 5(mGluR-5) dependent long-term potentiation (LTP) at excitatory synapses on fast-spikingGABAergic (FS-GABA) cells in the visual cortex.

Exploring the pathophysiology underlying clozapine‐induced enhancement of glutamatergic transmission through L‐glutamate and D‐serine release associated with pannexin1 hemichannels

British Journal of Pharmacology, EarlyView.
Abstract Background and purpose Clozapine, an approved antipsychotic for treatment‐resistant schizophrenia (TRS), enhances glutamatergic transmission by increasing exocytosis and non‐exocytosis glutamate release; however, its full action remained to be clarified.

Metabotropic glutamate receptor 5 binding in patients with obsessive-compulsive disorder [PDF]

The International Journal of Neuropsychopharmacology, 2014
Obsessive-compulsive disorder (OCD) is a disabling, mostly chronic, psychiatric condition with significant social and economic impairments and is a major public health issue. However, numerous patients are resistant to currently available pharmacological and psychological interventions.

Effect of age on brain metabotropic glutamate receptor subtype 5 measured with [18F]FPEB PET

NeuroImage, 2021
Objective: Metabotropic glutamate receptor subtype 5 (mGluR5) is integral to the brain glutamatergic system and cognitive function. This study investigated whether aging is associated with decreased brain mGluR5 availability.

Glutamate regulation of DARPP-32 phosphorylation in neostriatal neurons involves activation of multiple signaling cascades.

Proceedings of the National Academy of Sciences of the United States of America, 2005
Dopamine- and cAMP-regulated phosphoprotein of 32 kDa (DARPP-32) plays a central role in medium spiny neurons in the neostriatum in the integration of various neurotransmitter signaling pathways.
