Responses mediated by 5-HT3, nicotinic ACh and P2X receptors in the vagus nerve and strychnine-sensitive glycine receptors in the optic nerve were little or unaffected by ciprofloxacin (100 microM), BPAA (100 microM) or the combination of these drugs (both at 100 microM). 6.

The residual spontaneous and evoked EPSCs were abolished by the nicotinic receptor antagonist mecamylamine and the purinergic P2X receptor antagonist iso-PPADS.
While the glycine receptor antagonist strychnine had no effect on the firing activity, blockade of GABA (A) receptors with bicuculline significantly increased the firing rate in the majority of labeled NTS neurons.

Using loose-patch current-clamp recordings in brainstem slices from rat pups (postnatal day 7-12), we indeed show purinergic modulation of pH-sensitive RTN neurons: activation of P2X receptors indirectly inhibited RTN firing by increasing inhibitory input, whereas P2Y receptor stimulation caused direct excitation of RTN chemoreceptors.

Unlike Zn (2+), strychnine (5 microM), a glycine receptor antagonist, and (S),9 (R)-(-)-bicuculline methobromide (10 microM), a GABA (A) receptor antagonist, potentiated both fast polysynaptic reflex potential and slow ventral root potential.
