Cell type-specific ATP-activated responses in rat dorsal root ganglion neurons

摘要

1. The aim of our study is to clarify the relationship between expression pattern of P2X receptors and the cell type of male adult rat (Wistar) dorsal root ganglion (DRG) neurons. We identified the nociceptive cells of acutely dissociated DRG neurons from adult rats type using capsaicin sensitivity. 2. Two types of ATP-activated currents, one with fast, the other with slow desensitization, were found undr voltage-clamp conditions.
