Recently, the role of erythrocyte has been more emphasized, which also related with endothelial cell. For coronary artery patients, the endothelial nitric oxide synthase activity in red blood cell (RBC-eNOS activity) is lower than age-matched health people, and it is related with dysfunction of endothelial cell. In cardiovascular diseases. the erythrocyte arginase-1 is active and seize L-arginine with eNOS. When the Arg-1 stimulated by reactive oxygen species (ROS), the nitric oxide (NO) bioactivity decrease and produce more ROS, meanwhile, ROS can go around to stimulate Arg-1. When the RBC-NO production is lowering, it will increase the adhesion activity to endothelial cell due to erythrocyte can be quite close to blood vessel well then release Nitric Oxide, induce the dysfunction and oxidative pressure of endothelial cell. The NO can also regulate the deformability of erythrocytes, and extremely affect oxygen supply to tissue once the deformability and aggregation of erythrocyte become abnormal. Besides NO, the deformability will be affected if erythrocyte is continuously exposed to the endogenous or exogenous ROS, which also increase adhesion to endothelial cell with the exposure of phosphatidylserine. Exercise can regulate the mechanism of NO release from erythrocyte, affecting the rheology of erythrocyte, and improve the anti-oxidation ability. Therefore, as mentioned above which make erythrocyte, as many aspects, become an important role on atherosclerosis disease treatment.
