Facilitated mechanical sensitivity of C-fibre nociceptors in mice lacking IL-27/WSX-1 signalling. (a) Sample recordings of peri-stimulus time histogram. Abscissa: time in seconds. Ordinate: discharge rate of C-nociceptors. Lowest trace: force output of the mechanical stimulus. (b) Summarised mechanical response patterns. The response magnitude was significantly greater in WSX-1−/−, EBI3−/−, and p28−/− mice compared with WT. (a,b) WT (n = 28), WSX-1−/− (n = 29), EBI3−/− (n = 25), p28−/− (n = 19). P < 0.01–0.001. Kruskal-Wallis test followed by Dunn’s multiple comparison test. (c) Reduced mechanical response magnitude in EBI3−/− mice treated with rIL-27 compared with non-treated EBI3−/− mice. P < 0.001. Mann-Whitney U test. The data for non-treated EBI3−/− mice in panel c are identical to those of the EBI3−/− mice in panel b.
