10974307 Chen J, Heinke B, Sandkuhler J: Activation of group I metabotropic glutamate receptors induces long-term depression at sensory synapses in superficial spinal dorsal horn. Neuropharmacology. 2000 Sep;39(12):2231-43.

In the presence of bicuculline and strychnine, bath application of (1S,3R)-1-aminocyclopentane-1, 3-dicarboxylic acid ((1S,3R)-ACPD) or the specific group I mGluR agonist (S)-3,5-dihydroxyphenylglycine ((S)-3,5-DHPG) but not the specific group II mGluR agonist (2S,2'R,3'R)-2-(2', 3'-dicarboxycyclopropyl) glycine (DCG-IV) for 20 min produced an acute and a long-term depression of synaptic strength.
The phospholipase C inhibitor U73122 stereoselectively blocked the induction of long-term depression without affecting acute synaptic inhibition.

Along with the site for N-methyl-D-aspartate, which binds glutamate and/or aspartate, there have been identified a site for the binding of glycine (which is different from the strychnine sensitive one), a site for poliamines such as spermine and spermidine, and a site for the binding of Zn2+ (Table 1).
Both are coupled to a G protein and agonists exert their action increasing phospholipase C activity which in turn induces an increment of IP3 and diacyl-glicerol, and a consecutive releasing of Ca2+ from intracellular stores.

Given the results from the immunoblots and those of the toxin experiments, it is proposed that the transduction of the bitter taste of sucrose octaacetate in mice involves a receptor-mediated activation of a Gi-type protein which activates a phospholipase C to produce the two second messengers, IP3 and DAG.

Further, the inhibitory effects of glycine were prevented by low concentrations of strychnine (1 micromol/L) or incubation with chloride-free buffer.
Activation of VEGF receptor has been shown to result in activation of phospholipase C-gamma and increases in intracellular Ca (2+) concentration.

The action of high potassium solution on glycine release was prevented by BAPTA-AM, by depletion of intracellular Ca2+ stores by thapsigargin and by the phospholipase C inhibitor U-73122.

Strychnine, a glycine receptor blocker suggested to interfere with cholinergic sites of the efferent OHC synapse, was found to bind to OHC (cold strychnine for unspecific binding).
