Chronic glutamate toxicity in neurodegenerative diseases-what is the evidence?

Frontiers in Neuroscience, 2015
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 ...

Beyond the tumor: Enhancing pancreatic cancer therapy through glutamine metabolism and innovative drug delivery. [PDF]

J Cell Commun Signal
The top row shows key drivers‐KRAS, c‐Myc and HIF‐1a‐alongside gut and tumor microbiota, all converging on glutamine metabolism in PDAC. At the center, glutamine handling is depicted as the linchpin of tumor growth, biosynthesis and immune modulation. The green panel lists major intervention strategies: DON‐loaded nanoparticles, prodrugs (DRP‐104/JHU ...

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

, 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.

Determining the neurotransmitter concentration profile at active synapses [PDF]

, 2009
Establishing the temporal and concentration profiles of neurotransmitters during synaptic release is an essential step towards understanding the basic properties of inter-neuronal communication in the central nervous system.

Xanthurenic Acid Activates mGlu2/3 Metabotropic Glutamate Receptors and is a Potential Trait Marker for Schizophrenia

Scientific Reports, 2015
The kynurenine pathway of tryptophan metabolism has been implicated in the pathophysiology of psychiatric disorders, including schizophrenia. We report here that the kynurenine metabolite, xanturenic acid (XA), interacts with and activates mGlu2 and ...

Analyses of GWAS and Sub‐Threshold Loci Lead to the Discovery of Dendrite Development and Morphology Dysfunction Underlying Schizophrenia Genetic Risk

Advanced Science, EarlyView.
A cost‐effective strategy is developed analyzing sub‐threshold GWAS loci (5 × 10−8 < P ≤ 10−6), identifying 180 risk loci and 304 high‐confidence genes through combined GWAS/subGWAS analysis. This approach reveals dendrite development and morphogenesis (DDM) as a novel SCZ pathway.

Long-Term Depression of Striatal DA Release Induced by mGluRs via Sustained Hyperactivity of Local Cholinergic Interneurons

Frontiers in Cellular Neuroscience, 2021
The cellular mechanisms regulating dopamine (DA) release in the striatum have attracted much interest in recent years. By in vitro amperometric recordings in mouse striatal slices, we show that a brief (5 min) exposure to the metabotropic glutamate ...

Assembly and Cooperativity of Metabotropic Glutamate Receptors [PDF]

Biophysical Journal, 2015
Metabotropic glutamate receptors (mGluRs) are G-protein coupled receptors that are found throughout the nervous system where they respond to the major excitatory neurotransmitter, glutamate, to modulate synaptic transmission and plasticity via a variety of effectors.

Structural Basis of GABAB Receptor Activation during Evolution

Advanced Science, EarlyView.
This study explores the structural and functional mechanisms of the drosophila GABAB receptor, a key role in neurotransmission. Using cryo‐EM, the research reveals how the receptor's activation differs from its human counterpart, highlighting unique evolutionary features.
