(A) Protocol of experimental design for the mouse DNFB model. (B) Intrathecal administration of 3-oxa-PD1 (100 ng) reduced the number of scratching. Two-way ANOVA with Bonferroni’s post hoc test. F (1, 60) = 13.68, n=6 mice (vehicle) and n=8 mice (3-oxa-PD1). (C) Protocol of experimental design for the mouse psoriasis model induced by imiquimod (IMQ). (D) Intrathecal administration of 3-oxa-PD1 (100 ng) reduced the number of scratching. Two-way ANOVA with Bonferroni’s post hoc test. F (1, 60) = 13.68, n=6 mice (vehicle) and n=8 mice (3-oxa-PD1). Data are shown as mean ± SEM. *P < 0.05,
