BK and ATP but not NE or PGE2 increase the proportion of LVA-positive DRG neurons. (A) Exemplary current traces (left) and pie-charts summarizing the percentage of LVA-positive neurons (right) for DRG neurons individually treated with 100 nM BK, 2 μM ATP, 500 nM NE, 500 nM PGE2 or vehicle control (as indicated). (B) Statistical comparison of the proportion of LVA-positive neurons for each condition tested in (A); *, *** significantly different from the control group with P < 0.05 or P < 0.001; χ² test. (C) Summary of the LVA current amplitudes in LVA-positive neurons for each condition tested in (A). For (A–C) number of neurons is indicated within the charts; data from at least three independent preparations.
