A, Representative trace showing that 20μM ryanodine inhibits the calcium signal that is initiated by opening VGCC in a type III taste cell. B, Pooled results showing inhibition of the calcium signal due to opening VGCCs by 20μM ryanodine in type III cells (n=6, ***P= 0.0005). C, In type III taste cells that were sensitive to ryanodine, the evoked response was reduced an average of 50% by ryanodine (Inhibited). Compared to taste cells that were not sensitive to ryanodine (Not inhibited), this was a significantly larger inhibition (Student’s t-test, n=20, ***P=0.0001).
