Glutaminolysis drives membrane trafficking to promote invasiveness of breast cancer cells

open access: yesNature Communications, 2017
Glutamine metabolism is well known to support tumour growth. Here the authors show that cancer cells also utilize glutamine to promote invasiveness by converting it to glutamate, which upon secretion activates metabotropic glutamate receptors to ...

AMPA and Kainate Receptors Each Mediate Excitotoxicity in Oligodendroglial Cultures

open access: yesNeurobiology of Disease, 1999
Recent studies indicate that oligodendrocytes are vulnerable to excitotoxic insults mediated by glutamate receptors. The present study was carried out to characterize the type of glutamate receptors triggering cell death in optic nerve oligodendrocyte ...

Activation of group II metabotropic glutamate receptors blocks zinc release from hippocampal mossy fibers

open access: yesBiological Research, 2014
BACKGROUND: The hippocampal CA3 area contains large amounts of vesicular zinc in the mossy fiber terminals which is released during synaptic activity, depending on presynaptic calcium.

A Review of Molecular Imaging of Glutamate Receptors

open access: yesMolecules, 2020
Molecular imaging with positron emission tomography (PET) and single photon emission computed tomography (SPECT) is a well-established and important in vivo technique to evaluate fundamental biological processes and unravel the role of neurotransmitter ...

Near‐Infrared Organic Photovoltaic Electrodes for Subretinal Neurostimulation

open access: yesAdvanced Functional Materials, EarlyView.
Organic photovoltaic electrodes based on the D18:Y6 blend enable precise and light‐controlled activation of retinal ganglion cells in a degenerating retina. NIR Light‐driven activation of retinal ganglion cells, tunable stimulation parameters, and biocompatibility with human retinal organoids highlight their potential for next‐generation prosthetics ...

Nanoscale Mapping of the Subcellular Glycosylation Landscape

open access: yesAdvanced Science, EarlyView.
Using multiplexed super‐resolution imaging with fluorophore‐labeled lectins, this study reports intracellular glycosylation at the nanoscale across organelles and synaptic specializations. Extending glycan analysis beyond the cell surface, Glyco‐STORM reveals distinct glycosylation nanodomains in the ER, Golgi, lysosomes, and synaptic sites.

Metabotropic Glutamate Receptors for Parkinson's Disease Therapy

open access: yesParkinson's Disease, 2013
Excessive glutamatergic signalling within the basal ganglia is implicated in the progression of Parkinson’s disease (PD) and inthe emergence of dyskinesia associated with long-term treatment with L-DOPA.

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

open access: yesFrontiers 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 ...

Molecular docking studies of N-substituted 4-methoxy-6-oxo-1-aryl-pyridazine-3-carboxamide derivatives as potential modulators of glutamate receptors [PDF]

open access: yesResearch Results in Pharmacology, 2020
Introduction: The virtual target-oriented screening is a necessary stage of modern drug-design. In the present study, the affinity of pyridazine derivatives for the most promising antiparkinsonian biotargets – I–III groups of metabotropic and ionotropic ...

Vitamin D Regulates Olfactory Function via Dual Transcriptional and mTOR‐Dependent Translational Control of Synaptic Proteins

open access: yesAdvanced Science, EarlyView.
Vitamin D (VitD) modulates olfactory function by remodeling dendrodendritic synapses in tufted cells through vitamin D receptor‐dependent transcriptional and translational mechanisms. VitD regulates synaptic protein translation partially via mTOR signaling.
