Endothelin-1 (ET-1) causes pain through activation of nociceptors, by either direct depolarization or increased excitability. Here we examined the effect of ET-1 on nociceptor-associated tetrodotoxin-resistant (TTX-R) sodium currents using whole-cell voltage clamp of acutely dissociated rat dorsal root ganglion (DRG) neurons. DRG neurons that responded had(More)
Neuropathic pain is frequently associated with hyperexcitability of primary afferents, characterized by spontaneous impulses and repetitive firing. Electrophysiology and molecular biology reveal changes in dorsal root ganglion Na+ channels under conditions of neuropathic pain, but the manner by which these changes alter the physiology of sensory afferents(More)
