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

PLoS 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.

AMPA and Kainate Receptors Each Mediate Excitotoxicity in Oligodendroglial Cultures

Neurobiology 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 ...

Glutaminolysis drives membrane trafficking to promote invasiveness of breast cancer cells

Nature 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

Biological 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.
