Neuropeptide Y GERALD
NEUROPEPTIDE Y (NPY) was identified as a neuropeptide that is colocalized and coreleased with the neurotransmitter norepinephrine from sympathetic nerve terminals. In this regard, a large body of research on NPY focused on its role in autonomic physiology and pharmacology as a potentiator of the postsynaptic actions of norepinephrine. However, with the increased understanding of the genes and t...

متن کاملNeuropeptide Y: History and Overview
Neuropeptide Y (NPY) is a 36-amino acid peptide with structural similarities to peptide YY (PYY) and pancreatic polypeptide (PP). NPY, one of the most abundant neuropeptides known, is widely distributed throughout the central and peripheral nervous systems, while PYY and PP are predominantly distributed in the endocrine cells of the intestine and pancreas, respectively. Five NPY receptor subtyp...
متن کاملZinc deficiency increases hypothalamic neuropeptide Y and neuropeptide Y mRNA levels and does not block neuropeptide Y-induced feeding in rats.
Zinc deficiency reduces intake and produces an unusual approximately 3.5-d cycle of intake in rats. The mechanism underlying the anorexia and cycling has not yet been defined; current hypotheses suggest that alterations in amino acid metabolism and neurotransmitter concentrations may be a part of this anorexia. Recent reports indicate that appetite-stimulating neuropeptide Y (NPY) may be elevat...
متن کاملNew Antagonist Agents of Neuropeptide Y Receptors
The Neuropeptide Y (NPY) is a peptide of 36 amino acids, similar to the peptide YY (PYY) and to the pancreatic polypeptides (PP). At first, separated from the pig brain, the NPY is well-distributed in the mammals at the level of the central and peripheric nervous system. This neurotransmitter is present in strong concentrations in the nervous fiber of the brain, but equally as strong in the hea...
