Type III Na+ channels

Devor 1992). It appears likely that turning on of the previously silent type III Na+ channel gene contributes to the development of hyperexcitability of axotomi2ed DRG neurons. 

Additional analysis using subtype-specific antibodies revealed that the ectopic channel expression could be accounted for by increases in type II, but not type I or III Na channels (Fig. 2B) (Westenbroeck et al 1992).
