A Potent and Selective Inhibitor of the TTX-Resistant NaV1.8 Channel
产品形式
The TTX-resistant, NaV1.8 channel is expressed almost exclusively in the PNS and has been shown to mediate most of the well documented TTX-resistant currents of DRG neurons' action potentials3. Hyperexcitability, manifested by increased action potentialing and coded information transfer to the CNS of nociceptive DRG neurons, probably lie on the basis of several pathological pain states. Both genetic and pharmacological evidence suggest that NaV1.8 channel might serve as a target in pain control.
