Calcium influx in response to capsaicin was recorded from DRG cultured neurons incubated for 2 hours with paclitaxel (3 μM), AIBP 0.1 μg/mL, or paclitaxel+AIBP, and then loaded with Fluo-4. Neurons were buffered for 2 min, then stimulated for 15 sec with capsaicin (0.5 μM). See Supplemental Figure 3 for subsequent KCl stimulation. The maximal ΔF/F0 was quantified for the capsaicin response. Five to nine neuronal culture dishes from 4 different naïve wild type mice were stimulated in vitro. Total number of recorded cells per treatments: control(buffer)=19, paclitaxel=23, AIBP=15, and paclitaxel+AIBP=20. Mean±SEM; **, p<0.01. ***, p<0.001 (one-way ANOVA).
