Trends in (A) sodium ion channel current densities and (B) sodium ion channel mRNA levels in PHN, non-PHN and non-infected ND7/23-Nav1.8 cells.

1250 nM tetrodotoxin treatment selectively blocks the fast acting sodium ion channels Nav1.6 and Nav1.7.nd A direct comparison of tetrodotoxin treated PHN and non- PHN cells was not done.2Nav 1.3 levels were barely detectable.3p values between non-PHN and PHN infected cells.

1. 1250纳摩尔浓度的河豚毒素（tetrodotoxin）可选择性阻断快速激活型钠离子通道Nav1.6与Nav1.7。
2. 未对经河豚毒素处理的PHN细胞与非PHN细胞进行直接比较。
3. Nav1.3的表达水平几乎无法检测到。
4. 非PHN感染细胞与PHN感染细胞之间的p值。
