Isolated squid olfactory receptor neurons respond to dopamine and betaine with hyperpolarizing conductances. We used Ca(2+) imaging techniques to determine if changes in intracellular Ca(2+) were involved in transducing the hyperpolarizing odor responses. We found that dopamine activated release of Ca(2+) from intracellular stores while betaine did not change internal Ca(2+) concentrations. Application of 10 mM caffeine also released Ca(2+) from intracellular stores, suggesting the presence of ryanodine-like receptors. Depletion of intracellular stores with 100 microM thapsigargin revealed the presence of a Ca(2+) store depletion-activated Ca(2+) influx. The influx of Ca(2+) through the store-operated channel was reversibly blocked by 10 mM Cd(2+). Taken together, these data suggest a novel odor transduction system in squid olfactory receptor neurons involving Ca(2+) release from intracellular stores.
