Axon reflexes evoked by transient receptor potential vanilloid 1 activation are mediated by tetrodotoxin-resistant voltage-gated Na+ channels in intestinal afferent nerves

Capsaicin-sensitive nerves mediate axon vasodilator reflexes in the intestine, but the ion channels underlying action potential (AP) propagation are poorly understood. To examine the role of voltage-gated Na(+) channels underlying these reflexes, we measured vasomotor and electrophysiological respon...
