L-Glutamate supplementation improves small intestinal architecture and enhances the expressions of jejunal mucosa amino acid receptors and transporters in weaning piglets. [PDF]

open access: yesPLoS ONE, 2014
L-Glutamate is a major oxidative fuel for the small intestine. However, few studies have demonstrated the effect of L-glutamate on the intestinal architecture and signaling of amino acids in the small intestine.

The effect of combined glutamate receptor blockade in the NTS on the hypoxic ventilatory response in awake rats differs from the effect of individual glutamate receptor blockade. [PDF]

open access: yes, 2014
Ventilatory acclimatization to hypoxia (VAH) increases the hypoxic ventilatory response (HVR) and causes persistent hyperventilation when normoxia is restored, which is consistent with the occurrence of synaptic plasticity in acclimatized animals ...

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 ...

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 ...

Deciphering the Role of Cancer Stem Cells in Breast Cancer Brain Colonization Using a Novel Patient‐Derived Model

open access: yesAdvanced Healthcare Materials, EarlyView.
This study shows that stem‐like cells isolated from breast cancer brain metastases drive the spread and growth of tumors in the brain. Among them, a highly adhesive subgroup initiates metastasis and resists many drugs. By closely reflecting patient tumors, these models help identify new targets and improve the development of effective treatments ...

Mechanism of neuroprotective effect of mGluR4 agonists [PDF]

open access: yesResearch Results in Pharmacology, 2019
Introduction: This review of literature is to demonstrate a role of group III metabotropic glutamate receptors in maintaining the level of extracellular glutamate in ischemic stroke and neurodegenerative diseases.

A population of immature cerebellar parallel fibre synapses are insensitive to adenosine but are inhibited by hypoxia [PDF]

open access: yes, 2011
The purine adenosine plays an important role in a number of physiological and pathological processes and is neuroprotective during hypoxia and ischemia.

Functional Analysis of Ligand‐Gated Chloride Channels in a Cnidarian Sheds Light on the Evolution of Inhibitory Signaling

open access: yesAdvanced Science, EarlyView.
We uncover a large variety of putative inhibitory ligand‐gated ion channels (LGICs) in the phylum Cnidaria, the sister group to all bilaterian animals. Phylogenetic analysis suggests a complex evolutionary history of inhibitory LGICs with diverse neurotransmitter ligands.

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.
