Scientific background

Voltage-gated sodium channels (NaV) are essential for the generation of action potentials and for cell excitability1. NaV channels are activated in response to depolarization and selectively allow the flow of Na+ ions. To date, nine NaV α subunits have been cloned and named NaV1.1-NaV1.94-5. The NaV channels are classified into two groups according to their sensitivity to tetrodotoxin (TTX): TTX-sensitive (NaV1.1, NaV1.2, NaV1.3, NaV1.4, NaV1.6 and NaV1.7) and TTX-resistant (NaV1.5, NaV1.8 and NaV1.9)2-3.

Mammalian sodium channels are heterotrimers composed of a central, pore-forming α subunit and two auxiliary β subunits. The expression of the α subunit isoform is developmentally regulated and tissue specific. Na+ channels in the adult central nervous system and heart contain β1 through β4 subunits, whereas Na+ channels in adult skeletal muscle have only the β1 subunit6,8.

NaV1.7 is predominantly expressed in dorsal root ganglions (DRG) of the peripheral nervous system. Dominant gain of function mutations in the NaV1.7 gene are associated with erythermalgia (a rare autosomal disease characterized by sporadic burning pain accompanied by redness and heat in the extremities).9-11 Loss of function mutations in NaV1.7 channels leads to complete ablation of pain perception in humans.11 These recent findings highlight the role of this NaV isoform and the subset of DRG neurons that express this channel in physiological pain sensation.
