Effect of amiloride, mambalgin-1, APETx2 and PcTx1 on ASIC1b-expressing muscle afferent DRG neurons. (A) Whole-cell patch clamp recording on an ASIC1b-expressing DRG neuron projecting to gastrocnemius muscle labeled by fluorogold. (B) Mambalgin-1 (MB-1) (1 μM) inhibited acid (pH 5.0)-induced currents in 13 of 14 ASIC1b-expressing muscle afferent DRG neurons. (C) APETx2 (1 μM) inhibited acid (pH 5.0)-induced currents in 6 of 13 ASIC1b-expressing muscle afferent DRG neurons. (D) PcTx1 (100 nM) inhibited acid (pH 5.0)-induced currents in 5 of 11 ASIC1b-expressing muscle afferent DRG neurons.
