Renal effects of neuropeptide Y

Pfl�gers Archiv European Journal of Physiology, 1998
Neuropeptide Y (NPY) is a co-transmitter of the sympathetic nervous system including the renal nerves. The kidney expresses NPY receptors, which can also be activated by peptide YY (PYY), a circulating hormone released from gastrointestinal cells. Five subtypes of NPY receptors have been cloned, among which Y1, Y2 and Y5 appear to be involved in the ...

Microcirculatory Dynamics of Neuropeptide Y

Microvascular Research, 1994
We used the hamster cheek pouch microcirculation to investigate by intravital microscopy the effects of neuropeptide Y (NPY) on arteriolar diameter, leukocyte adhesion to microvascular endothelium, and postcapillary venular permeability. We applied NPY topically for 3 min at concentrations of 10(-7), 10(-9), and 10(-11) M.

Metabolism and functions of neuropeptide Y

Neurochemical Research, 1996
Neuropeptide Y is one of the most abundant neuropeptides in the central and peripheral nervous systems and its sequence is highly conserved among species. A number of key physiological roles for NPY are now emerging, especially in the control of feeding and energy homeostasis. Other physiological actions of NPY are also reviewed.

Quantitative microdialysis of neuropeptide Y

Journal of Neuroscience Methods, 1995
The feasibility of using the difference method of quantitative microdialysis to measure neuropeptide Y (NPY) was evaluated in vitro and in vivo. The accuracy of this method was tested in vitro under steady-state conditions for 3 test solutions containing known concentrations of NPY. The estimated concentrations of NPY were 1.2 +/- 0.6, 3.7 +/- 0.9, and

Neuropeptide Y and Sympathetic Neurotransmissiona

Annals of the New York Academy of Sciences, 1990
The coexistence of neuropeptide Y (NPY) with noradrenaline (NA) in perivascular nerves as well as in sympathetic nerves to muscle in the heart, spleen and vas deferens suggests a role for NPY in autonomic transmission. Sympathetic nerve stimulation or reflexogenic activation in experimental animals or man are associated with NPY release as revealed by ...

Introduction to the reviews on neuropeptide Y

Neuropeptides, 2004
Neuropeptide Y (NPY) was first reported as an abundant peptide in brain tissue in 1982. Shortly thereafter, NPY was found to be a member of a peptide family consisting of the endocrine peptides pancreatic polypeptide (PP) and peptide YY (PYY). These peptides exert most of their biological effects through five G-protein coupled receptors termed Y1, Y2 ...
