Pharmacological characterization of ET-1 and BK activated SOCE in rat TG neurons. (a) Summary of changes in single-cell intracellular Ca2+ concentration as a measurement of SOCE induced by administration of ET-1 or BK in the presence or absence of various ion channel inhibitors: PyR3 (10 µM, TRPC3), Gd3+ (10 µM, ORAI), or combination of both. (b) Data from panel (a) as represented by percentage of maximal response inhibited by PyR3, Gd3+, or combination of both. (c) Summary of Orai1 ion channel contribution to ET-1- and BK-induced SOCE in rat TG neurons (single-cell measurements). (d) Summary of TRPC3 ion channel contribution to ET-1- and BK-induced SOCE in rat TG neurons (single-cell measurements). Statistical significance was assessed by two-way ANOVA with Bonferroni correction, n = 6–9, *p < .05. **p < .01. ***p < .001. ET-1 = endothelin-1; BK = bradykinin; SOCE = store-operated Ca2+ entry; TG = trigeminal ganglia; TRPC3 = transient receptor potential canonical channel 3; ORAI = ▪ ▪ ▪; ANOVA = analysis of variance.
