    Adenosine 5′-triphosphate and neuropeptide Y are co-transmitters in conjunction with noradrenaline in the human saphenous vein
    (1999) Racchi, H; Irarrázabal, MJ; Howard, M; Morán, S; Zalaquett, R; Huidobro-Toro, JP
    1 Human saphenous veins were used to assess the cooperative participation of adenosine 5-triphosphate (ATP), neuropeptide Y (NPY), and noradrenaline (NA) in the vasomotor responses elicited following electrical depolarization of the perivascular nerve terminals. Rings from recently dissected human biopsies were mounted to record isometric muscular contractions; the motor activity elicited in the circular muscle layer following electrical depolarization (2.5-20 Hz, 50 V, 0.5 msec) were recorded.
