Fig. 2. AP2α2 knockdown disrupts the development and maintenance of thermal sensitivity in chronic inflammatory pain.

Fig. 2

a Thermal sensitivity of animals in the CFA pain model with a pre-inflammatory knockdown paradigm for scrambled (n = 11) and AP2α2 (n = 12) shRNA groups. Data is pooled males and females and is represented as mean paw withdrawal latency (PWL) ± S.E.M. Significance determined using repeated measures 2-way ANOVA with Bonferroni correction p < 0.05; *p < 0.01; ** Day 8: Ipsilateral Scrambled shRNA vs Ipsilateral AP2α2 shRNA p-value = 0.0398. Day 12: Ipsilateral scrambled shRNA vs Ipsilateral AP2α2 shRNA p-value = 0.0048. Day 16: Ipsilateral scrambled shRNA vs ipsilateral AP2α2 shRNA p-value = 0.0013. b von Frey withdrawal threshold of ipsilateral hind paw in a chronic inflammatory pain model where knockdown occurred before inflammation was initiated. Data for the scrambled (n = 8) and AP2α2 (n = 8) shRNA groups is pooled, males and females, and is represented as mean percentage of baseline ± S.E.M. Significance determined using repeated measures 2-way ANOVA with Bonferroni correction p < 0.05; *. Day 13: Scrambled shRNA vs AP2α2 shRNA p-value = 0.0315. Contralateral PWT can be found in Supplementary Fig. 2. c Thermal sensitivity of animals injected with scrambled (n = 8) and AP2α2 (n = 8) shRNAs following establishment of inflammation. Data is pooled males and females and is represented as mean PWL ± S.E.M. Significance determined using repeated measures 2-way ANOVA with Bonferroni correction p < 0.05; *p < 0.01; **. Day 9: Ipsilateral scrambled shRNA vs ipsilateral AP2α2 shRNA p-value = 0.0251. Day 13: Ipsilateral scrambled shRNA vs Ipsilateral AP2α2 shRNA p-value = 0.0064.
