Fig. 1 Hyperalgesic priming induces a switch in nociceptor second messenger signaling pathways. In a naïve animal, administration (hindpaw injection) of an inflammatory stimulus (e.g., PGE2) results in transient Gs/PKA-mediated…
Fig. 1 Opioids were applied in the volar forearm of volunteers by dermal microdialysis. Intensity of opioid-induced maximum itch is shown in (a) (visual analog scale 0–10, mean ± SEM). (b) Peak…
