NPY reduces neuropathic mechanical hypersensitivity and light touch-evoked c-Fos expression in Y1R+ dorsal horn neurons. (A) von Frey thresholds 14 days after SNI before (pre-injection) and 60 min after intrathecal injection of saline or NPY (post-injection). Non-noxious mechanical stimulus-evoked expression of Fos-immunoreactivity in lamina I-II (B) for all neurons and (C) in Y1R-immunoreactive neurons. N = 6–9. ★P < 0.05 compared to control. Data represent mean ± SEM. Dots represent individual subjects in the analysis.
