Ethanol modulates the ionic permeability of sodium channels in rat sensory neurons

Abstract: The effects of ethanol on tetrodotoxin-sensitive (TTXs) and tetrodotoxin-resistant (TTXr) sodium channels in rat spinal ganglia were studied using a patch-clamp method. Application of ethanol (10 and 100 mM) to both sides of membranes resulted in decreases in the reversion potentials of both types of sodium channels. In the case of TTXr channels, ethanol decreased their selectivity in relation to Na ions and altered the sequence of ion selectivity of these channels for different cations from row X to row XI of… Show more

“…Furthermore, it is likely that toluene and ethanol differ in the way they interact with sodium channels because, as evidenced by the I – V curves obtained in this study, toluene did not change the reversal potential of Na + channels in oocytes. In contrast, 10–100 m M ethanol applied to Na + channels in rat sensory neurones significantly decreased the reversal potential ( Krylov et al , 2000 ).…”
