Amiloride does not block taste transduction in the mouse (Slc:ICR).
1. The receptor potential of the mouse taste cell was recorded with an intracellular microelectrode while taste stimuli were applied to the tongue surface of the anesthetized mouse. 2. A membrane depolarization accompanied by an increase in membrane resistance was observed after a sucrose stimulus. 3. A sodium-chloride stimulus initiated a membrane depolarization accompanied by a decrease in membrane resistance. 4. Amiloride elicits a depolarization of the membrane and is accompanied by an increase in membrane resistance. 5. Pre-adapting the tongue to amiloride, which is known as a potent sodium channel blocker, did not alter the responses to sodium-chloride and other taste stimuli.
