Confocal images showing the effect of RTX on TRPV1- and δ-opioid receptor-immunoreactive dorsal root ganglion (DRG) neurons and afferent terminals in the spinal cord. A: representative confocal images showing δ-opioid receptor (green)- and TRPV1 (red)-immunoreactivity DRG neurons from one vehicle control and one RTX-treated rat. B: confocal images showing TRPV1 (green)- and δ-opioid receptor (red)-immunoreactivity in afferent terminals in the spinal dorsal horn of one vehicle control and one RTX-treated rat. Co-localization of the TRPV1- and δ-opioid receptor-immunoreactivity is indicated in yellow when two images are digitally merged. All images are single confocal optical sections.
