In 3 neurones, GR73632 evoked both a depolarising response and inhibitory postsynaptic potentials (IPSPs) and in the one neurone tested, the IPSPs were blocked by strychnine (20 microM), suggesting that NK1 receptors may also be found upon inhibitory glycinergic interneurones.

Activation of spinal neurokinin1 (NK1) receptors leads to increases in the extracellular concentration of glycine in the dorsal horn.
However, in the presence of the glycine antagonists, strychnine or phenylbenzene-omega-phosphono-alpha-amino acid (PMBA), GR82334 displayed inhibitory properties.

Lamina I and III neurokinin 1 (NK1) receptor expressing (NK1R+) dorsal horn neurons, many of which are projection neurons, are required for the development of this hypersensitivity and are therefore likely to be a component of this proposed pathway.
Blockade of local GABAergic and glycinergic inhibition with bicuculline (10 microm) and strychnine (300 nm), respectively, revealed significant A fiber input to lamina I NK1R+ neurons that was predominantly Abeta fiber mediated.

Capsaicin-induced depolarization was maintained in 20 out of 32 (63%) SG neurons in the presence of amino acid and voltage-dependent sodium channel blockers (10 microM CNQX, 20 microM AP-5, 0.5 microM TTX, 50 microM picrotoxin and 2 microM strychnine).
In addition, capsaicin-induced depolarization was maintained in the presence of L-732,138 (1 microM), an NK1 receptor antagonist, in 14 out of 17 neurons (82%) tested.

The modulatory effect of substance P (SP) on strychnine-sensitive glycine (Gly) response was examined in neurons acutely dissociated from the rat sacral dorsal commissural nucleus (SDCN) using nystatin perforated patch recording configuration under voltage-clamp conditions.

The compounds do not appear to act through the strychnine-insensitive glycine binding site because neither beta-amyloid (25-35) nor substance P displaced [3H] glycine binding.

First, we showed that glycine disinhibition with strychnine selectively induced dynamic but not static mechanical allodynia.
