Percent change of baseline RBF in response to decreasing renal perfusion during P2 and A₁ receptor antagonism. A: percent change from baseline RBF in response to decreasing renal perfusion pressure with (○) and without (●) P2 receptor antagonism by PPADS. B: percent change from baseline RBF in response to decreasing renal perfusion pressure with adenosine A₁ receptor inhibition by DPCPX (○) and during DMSO vehicle infusion (▾). For comparison, saline vehicle experiments (●) are reproduced from A. *P < 0.05 vs. baseline. #P < 0.05 between saline vehicle.
