Fig. 4. P2-receptor antagonists reduce the cytosolic Ca2+
elevations. Inhibitors (100 µM each) were applied 8 minutes prior to
agonist application. The P2Y1-receptor-specific antagonist MRS2179
reduced the Ca2+ signal evoked by ATP or ADP (50 µM each). The
non-selective P2-receptor antagonists suramin or PPADS reduced the
Ca2+ signals evoked by either ATP, ADP or UTP (mean±s.d.,
n=5-8, *P<0.05,
**P<0.01).
