General description

Quisqualate/ Quisqualic acid is obtained from the fruits and seeds of Quisqualis chinensis. It is an agonist at two subsets of excitatory amino acid receptors metabotropic receptors that indirectly mediate calcium mobilization from intracellular stores and, ionotropic receptors that directly control membrane channels. L-quisqualic acid is an agonist of the neurotransmitter L-glutamate.

Application

Quisqualic acid has also been used as a group I metabotropic receptor agonist in neurons.
Quisqualic acid has been used to test ligand-gated receptors in spiral ganglion neurons.

Biochem/physiol Actions

Active enantiomer of quisqualic acid; excitatory amino acid at glutamate receptors.

The metabotropic glutamate receptors (mGluRs) are evolutionarily conserved from nematodes to vertebrates. The Caenorhabditis elegans (C. elegans) genome contains three mGluR genes referred to as mgl-1, mgl-2, and mgl-3. The aim of this study was to characterize the pharmacological profiles

We have previously reported that exposure of SH-SY5Y neuroblastoma cells to unconjugated bilirubin (UCB) resulted in a marked up-regulation of the mRNA encoding for the Na(+)-independent cystine∶glutamate exchanger System X(c)(-) (SLC7A11 and SLC3A2 genes). In this study we demonstrate that

Little is known about the generation of slow rhythms in brain neuronal circuits. Nevertheless, a few studies, both from reconstituted systems and from hippocampal slices, indicate that activation of metabotropic glutamate receptors (mGluRs) could generate such rhythms. Here we show
