Bafilomycin A1, a specific inhibitor of V-ATPase inhibitor, blocks extracellular surface acidification of goldfish HCs induced by 20 μM kainate or 50 mM K⁺. A Kainate-induced acidification is blocked by 0.4 μM bafilomycin A1, and partially recovered after 10 min wash-out and then fully recovered after 20 min wash-out; B 0.4 μM bafilomycin A1 suppressed 50 mM K⁺-induced HC acidification, which was recovered after 13 min wash-out (from Jouhou et al. [29])
