The molecular mechanism of pH sensing by chemoreceptors is not clear, although it had been proposed to be mediated by a drop in ... Extracellular acidosis evoked transient inward currents in glomus cells that were evident at pH 7.0 and half-activated (pH 50) ... Recently, pH-sensitive ion channels have been described in glomus cells that respond directly to extracellular acidosis. In ... by recording the responses of glomus cells isolated from rat carotid body to rapid changes in extracellular pH using whole-cell ...
