Figure 5. Effect of donor age on RBC responses to Mas 7.

Figure 5.

A: the Gi activator Mas 7 increased intracellular cAMP similarly from RBCs of young and older adults. B: extracellular ATP (i.e. ATP release) from RBCs of young and older adults was unaffected by incubation with saline (vehicle and time control) and increased significantly following incubation with Mas 7. ◊P < 0.05 vs. zero; *P < 0.05 vs. saline
