Snake Sodium Channels Resist TTX Arrest

Snake Sodium Channels Resist TTX Arrest

In parts of western North America, garter snakes dine readily on newts because they have a marked resistance to TTX. Research by Geffeney et al explores how these snakes avoid TTX poisoning and implicate voltage-gated sodium channels in muscle as the site of TTX resistance.
