Neuropeptide Y (NPY) is contained in and coreleased with norepinephrine (NE) from
sympathetic nerves innervating vascular and cardiac tissues. The effects of NPY infusion on …

Neuropeptide Y (NPY) is a peptide with vasoconstrictor properties known to be present in
the central nervous system as well as in sympathetic nerve endings and the adrenal …

The modulation of cardiovascular sympathetic responses by neuropeptide Y (NPY) and
peptide YY (PYY) was assessed in vivo, in pithed rats. Both peptides (0.02–2 nmol/kg) …

The sympathetic co-transmitter neuropeptide Y (NPY) inhibits cardiac contractility in vivo in
the rat heart. We tested whether NPY alters the force of contraction or the activity of …

Neuropeptide Y (NPY) is co-released with noradrenaline from sympathetic nerves, has a
strong vasoconstrictive action, and causes an attenuation of parasympathetic action in …

Neuropeptide Y (NPY) causes vasoconstriction through Y1-receptors and inhibits vagal
bradycardia through presynaptic Y2-receptors. These effects of NPY were investigated in …

Neuropeptide Y (NPY) infusions into isolated, perfused, spontaneously beating hearts of
guinea pigs elicited concentration-dependent increases of myocardial perfusion pressure …

The effects of neuropeptide Y (NPY) on blood pressure and heart rate were studied in pithed
rats. Systemic infusion of NPY in a dose (230 pmol× kg− 1× min− 1) which per se did not …

We have studied the hemodynamic effects of neuropeptide Y (NPY) and its COOH-terminal
fragment NPY-(18–36) in conscious rats. Intra-arterial injection of NPY rapidly elevated …

The haemodynamic effects of intracerebroventricular (icv) administration of neuropeptide Y
(NPY) in urethane-anaesthetized rats were studied. In Sprague-Dawley rats, NPY increased …
