The results of the present study show that human platelets take up L-arginine by two transport systems which are compatible with the systems y + and y + L. These Na + -independent transporters have been distinguished by treat-ing platelets with N-ethylmaleimide that blocks selectively systemy + .Systemy + , that accounts for 30–40%of the total transport, is characterized by low affinity forL-arginine, is unaffected byL-leucine, is sensitive to changes of membrane potential and totrans-stimulation. ...
