Anaesthetised rats and dogs were used to study the pre-and postjunctional actions of
neuropeptide Y (NPY) and [Pro 34] NPY simultaneously. Increases in arterial blood pressure …

The effects of neuropeptide Y (NPY) and related peptide fragments on blood pressure and
vagal action at the heart were compared in the anaesthetized rat. A change in vagal action …

Neuropeptide Y (NPY), a sympathetic cotransmitter, has both prejunctional and
postjunctional actions in the cardiovascular system. In the bioassay system used here NPY …

The effects of neuropeptide Y (NPY), peptide YY (PYY), desamido-NPY and five C-terminal
fragments of NPY or PYY were tested on different smooth muscle preparations in vitro. The …

Neuropeptide Y (NPY) is widely distributed in central and peripheral neurons. In sympathetic
postganglionic neurons, NPY coexists with noradrenaline. NPY and its structural relative …

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 presence of receptor subtypes mediating the vascular and prejunctional effects of
neuropeptide Y (NPY) was investigated using the Y 2 receptor agonist, NPY-(13–36), and …

The cardiovascular actions of intracerebroventricular (icv) administration of neuropeptide Y
(NPY) were examined in conscious, unrestrained rats. A prolonged decrease in heart rate …

Pre-and postjunctional responses to nerve released or exogenous neuropeptide Y (NPY)
were measured in the anaesthetised dog before and after administration of D-myo-inositol-1 …

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