Neuropeptide Y (porcine)

* Please kindly note that our products are not to be used for therapeutic purposes and cannot be sold to patients.

Neuropeptide Y (porcine) is a widely distributed endogenous neuropeptide involved in regulation of circadian rhythms, sexual functioning, anxiety and stress response, and regulation of food intake (Ki= 0.17, 0.04 nM at human and Y2 respectively). It inhibits cholecystokinin- and secretin-stimulated pancreatic secretion.

1. Neuropeptide Y in the adult and fetal human pineal gland
Morten Møller, Pansiri Phansuwan-Pujito, Corin Badiu Biomed Res Int . 2014;2014:868567. doi: 10.1155/2014/868567.
Neuropeptide Y was isolated from the porcine brain in 1982 and shown to be colocalized with noradrenaline in sympathetic nerve terminals. The peptide has been demonstrated to be present in sympathetic nerve fibers innervating the pineal gland in many mammalian species. In this investigation, we show by use of immunohistochemistry that neuropeptide Y is present in nerve fibers of the adult human pineal gland. The fibers are classical neuropeptidergic fibers endowed with large boutons en passage and primarily located in a perifollicular position with some fibers entering the pineal parenchyma inside the follicle. The distance from the immunoreactive terminals to the pinealocytes indicates a modulatory function of neuropeptide Y for pineal physiology. Some of the immunoreactive fibers might originate from neurons located in the brain and be a part of the central innervation of the pineal gland. In a series of human fetuses, neuropeptide Y-containing nerve fibers was present and could be detected as early as in the pineal of four- to five-month-old fetuses. This early innervation of the human pineal is different from most rodents, where the innervation starts postnatally.
2. Potentiation by neuropeptide Y of 5HT2A receptor-mediated contraction in porcine coronary artery
Akira Toyosato, Tatsuru Tsurumaki, Shingo Nagai, Hiroshi Higuchi, Xu Bo Eur J Pharmacol . 2006 Aug 21;544(1-3):111-7. doi: 10.1016/j.ejphar.2006.06.036.
Potentiation by neuropeptide Y of serotonin (5-HT)-induced vasoconstriction was investigated in porcine coronary artery. 5-HT caused concentration-dependent contraction through 5-HT2A receptors. Neuropeptide Y (30 nM) significantly increased the 5HT-induced contraction by 16+/-5% in arteries with intact endothelium. Removal of the endothelium abolished the potentiation. A neuropeptide Y1 antagonist, BIBP3226, blocked this neuropeptide Y-induced potentiation. In vessels with intact endothelium, the potentiation by neuropeptide Y was inhibited by in the presence of a cyclo-oxygenase inhibitor, indomethacin (30 microM), but not by the presence of ETA or ETB endothelin receptor antagonists or an NO synthase inhibitor, NG-nitro-L-arginine (L-NNA) (1 mM) at all. A thromboxane A2 (TXA2) synthase inhibitor, ozagrel, and prostanoid TP receptor antagonists, seratrodast and ONO-3708, also inhibited the neuropeptide Y-induced potentiation. In the endothelium-denuded arteries, a prostanoid TP receptor agonist, U-46619 (0.01-0.1 nM), potentiated 5-HT-induced contraction. These results indicate that neuropeptide Y potentiates the 5-HT-induced contraction, due to release of TXA2 from the endothelium via neuropeptide Y1 receptors, in porcine coronary artery.
3. Distribution of somatostatin- and neuropeptide Y-immunoreactive nerve fibers in the porcine female reproductive system
M Lakomy, N Yanaihara, M Majewski, O Häppölä Neurosci Lett . 1991 Jan 28;122(2):273-6. doi: 10.1016/0304-3940(91)90876-u.
The localization and distribution of somatostatin and neuropeptide Y were studied in the porcine female reproductive system with the indirect immunofluorescence technique. Somatostatin-immunoreactive nerve fibers were observed in different parts of the ovary and in the muscular membrane of the uterus as well as in the mesosalphinx. Somatostatin-immunoreactive neurons were detected in the inferior mesenteric ganglion. Neuropeptide Y immunoreactivity was present in a large number of nerve fibers distributed in different regions of the uterus, oviduct and ovary. The present results suggest that the porcine female genital organs receive innervation by somatostatin- and neuropeptide Y-containing nerve fibers, but their exact functional role remains to be established.
