Abnormal pain sensitivity associated with inherited and acquired pain disorders occurs through increased excitability of peripheral sensory neurons in part due to changes in the properties of voltage-gated sodium channels (Navs). Resurgent sodium currents (I(NaR)) are atypical currents believed to be associated with increased excitability of neurons and may(More)
Chronic and neuropathic pain constitute significant health problems affecting millions of individuals each year. Pain sensations typically originate in sensory neurons of the peripheral nervous system which relay information to the central nervous system (CNS). Pathological pain sensations can arise as result of changes in excitability of these peripheral(More)
Paroxysmal extreme pain disorder (PEPD) and inherited erythromelalgia (IEM) are inherited pain syndromes arising from different sets of gain-of-function mutations in the sensory neuronal sodium channel isoform Nav1.7. Mutations associated with PEPD, but not IEM, result in destabilized inactivation of Nav1.7 and enhanced resurgent sodium currents. Resurgent(More)
The use of induced pluripotent stem cells (iPSCs) for the functional replacement of damaged neurons and in vitro disease modeling is of great clinical relevance. Unfortunately, the capacity of iPSC lines to differentiate into neurons is highly variable, prompting the need for a reliable means of assessing the differentiation capacity of newly derived iPSC(More)
Voltage-gated sodium (Nav) channel inhibitors are used clinically as analgesics and local anesthetics. However, the absence of Nav channel isoform selectivity of current treatment options can result in adverse cardiac and central nervous system side effects, limiting their therapeutic utility. Human hereditary gain- or loss-of-pain disorders have(More)
