Outline of Final Research Achievements |
We evaluated whether a c-fos-enhanced green fluorescent protein (eGFP) transgenic rat line can be useful for the study of nociceptive pathways and processing. A comparison of eGFP in transgenic rats and Fos-like immunoreactivity (LI) in wild type rats was made in the dorsal spinal cord, paraventricular nucleus (PVN) and supraoptic nucleus (SON). Oxytocin-LI (OXT-LI) was carried out to examine the activation of OXT neurons in the PVN and SON. Following acute nociceptive stimuli, eGFP was maximally expressed at 6 h in the spinal cord and 3 h in the PVN and SON, whereas, Fos-LI was maximally expressed at 1.5 h in all the regions we analyzed. Induction of eGFP in the OXT neurons was more sensitive than that of Fos after acute nociceptive stimuli. These results suggested that the c-fos-eGFP transgenic rat line can be useful for the study of nociceptive pathways and processing.
