10051215 Nabekura J, Xu TL, Rhee JS, Li JS, Akaike N: Alpha2-adrenoceptor-mediated enhancement of glycine response in rat sacral dorsal commissural neurons. Neuroscience. 1999 Mar;89(1):29-41.

In addition, noradrenaline potentiated the strychnine-sensitive postsynaptic currents evoked in a slice preparation of sacral dorsal commissural nucleus.
N-[2 (methylamino) ethyl]-5-isoquinoline sulfonamide dihydrochloride, protein kinase A inhibitor, mimicked the effect of noradrenaline on glycine response.

9518725 Han Y, Slaughter MM: Protein kinases modulate two glycine currents in salamander retinal ganglion cells. J Physiol. 1998 May 1;508 ( Pt 3):681-90.

Nanomolar concentrations of strychnine selectively blocked the fast phase of the glycine current and reversed the effect of OAG, but not that of forskolin.
H-89, a protein kinase A (PKA) inhibitor, blocked the effect of forskolin. 4.

We identified the inhibitory (strychnine-sensitive) glycine receptor as a specific target of PGE (2).
Inhibition of glycine receptors occurred via a postsynaptic mechanism involving the activation of EP2 receptors, cholera-toxin-sensitive G-proteins and cAMP-dependent protein kinase.

We found previously that unilateral cochlear ablation (UCA) in young adult guinea pigs decreased [3H] strychnine binding activity in several brain stem auditory nuclei.
This study determined if the UCA-induced deficit could be regulated by protein kinase C (PKC), protein kinase A (PKA) or Ca2+/calmodulin-dependent protein kinase II (CaMKII).

In addition, activation of adenylyl cyclase, with forskolin, and cAMP-dependent protein kinase, with Sp-cAMPS, caused a larger increase in IPSCs in slices from morphine-treated animals.

In retina, we found a strychnine-insensitive glycine response in bipolar and ganglion cells.
It was G-protein mediated and protein kinase A dependent.

The increase in synaptic NMDA receptor clustering was prevented by addition of a protein kinase A inhibitor or by coexposure to a low concentration of NMDA and was reversed when ethanol was removed from the cultures.

In non-inhibited motoneurones, neither bicuculline nor strychnine markedly changed inspiratory drive currents.
Inhibitory currents in XII motoneurones were potentiated by protein kinase A (PKA) activity.

Both currents were antagonized by 10 (-6) M strychnine, thus indicating that taurine acts on strychnine-sensitive glycine receptor on the SN neurons. 3.

In the presence of strychnine and picrotoxin, ganglion cells responded to light onset and offset with transient inward currents at -70 mV.
