(A) Normalized caffeine-induced Ca2+ transients before and after AngII stimulation (20 min) in Ctrl (black), in presence of gp91ds-tat (1 µmol/L, grey) or FTY720 (200 nmol/L, light-grey). Bar graphs show (B) caffeine transient decay constant (τcaff) and (C) amplitude under Ctrl conditions and in presence of gp91ds-tat or FTY720. (*: p < 0.05 compared to CtrI).
