(A) Schematic illustration of the experiment showing the timeline of systemic chemical sympathectomy (cSYMPX), injections of paclitaxel (PAX), and behavioral and histochemical (IHC) assays. (B) Time course of paclitaxel-induced mechanical allodynia in mice (n=5 male mice/group, two-way ANOVA showed significant difference between cSYMPX and vehicle groups, Group × Time interaction: F6,48 = 12.02, p < 0.001; Bonferroni post hoc analysis revealed a significant difference between groups on day 3, 5 and 14. *p < 0.05, **p < 0.01, ***p < 0.001). (C) Representative images and quantification of tyrosine hydroxylase (Th) protein in DRG tissues of vehicle- and cSYMPX treated mice at day 21 of paclitaxel (n=3 male mice/group, t-test, *p = 0.017 compared to vehicle).
