Interactions of Glucocorticoids, NPY and Hypothalamic Serotonin.

Nutritional neuroscience

Habash T, Eskay RL, Kuenzel WJ, Castonguay TW.
PMID: 27414052
Nutr Neurosci. 2000;3(3):183-92. doi: 10.1080/1028415X.2000.11747315.

Neuropeptide Y (NPY), insulin, corticosterone (CORT) and 5-hydroxytryptamine (5-HT), or serotonin, are all involved in energy homeostasis. To show how they might interact, the effects of NPY on plasma insulin and on 5-HT metabolism in the paraventricular hypothalamic nucleus...

Hypothalamus-adipose tissue crosstalk: neuropeptide Y and the regulation of energy metabolism.

Nutrition & metabolism

Zhang W, Cline MA, Gilbert ER.
PMID: 24959194
Nutr Metab (Lond). 2014 Jun 10;11:27. doi: 10.1186/1743-7075-11-27. eCollection 2014.

Neuropeptide Y (NPY) is an orexigenic neuropeptide that plays a role in regulating adiposity by promoting energy storage in white adipose tissue and inhibiting brown adipose tissue activation in mammals. This review describes mechanisms underlying NPY's effects on adipose...

Retinal Pigment Epithelial Cell Line Suppression of Phagolysosome Activation.

International journal of ophthalmology & eye science

Taylor AW, Dixit S, Yu J.
PMID: 25905107
Int J Ophthalmol Eye Sci. 2015 Jan 29;(1):1-6.

The eye is an immune privileged tissue with multiple mechanisms of immunosuppression to protect the light gathering tissues from the damage of inflammation. One of theses mechanisms involves retinal pigment epithelial cell suppression of phagosome activation in macrophages. The...

The effect of Ramadan fasting on serum leptin, neuropeptide Y and insulin in pregnant women.

Medical journal of the Islamic Republic of Iran

Khoshdel A, Kheiri S, Nasiri J, Tehran HA, Heidarian E.
PMID: 25664293
Med J Islam Repub Iran. 2014 Sep 14;28:92. eCollection 2014.

BACKGROUND: Many pregnant Muslim women choose to fast during Ramadan every year worldwide. This study aimed to examine the effect of Ramadan fasting on serum leptin, neuropeptide Y and insulin in pregnant women and find whether fasting during pregnancy...

Controlling feeding behavior by chemical or gene-directed targeting in the brain: what's so spatial about our methods?.

Frontiers in neuroscience

Khan AM.
PMID: 24385950
Front Neurosci. 2013 Dec 18;7:182. doi: 10.3389/fnins.2013.00182.

Intracranial chemical injection (ICI) methods have been used to identify the locations in the brain where feeding behavior can be controlled acutely. Scientists conducting ICI studies often document their injection site locations, thereby leaving kernels of valuable location data...

Concentration of neuropeptide Y, galanin, &bgr;-endorphin, vasoactive intestinal peptide and gonadotropin releasing hormone in the hypothalamus of gilts during the estrous cycle.

Neuro endocrinology letters

Ziecik AJ, Okrasa S, Kalamarz H, Lakomy M, Kraeling RR.
PMID: 11458205
Neuro Endocrinol Lett. 1999;20(6):397-403.

Numerous reports indicate that peptides isolated from the brain such as beta-endorphin (beta-END), neuropeptide Y (NPY), galanin (GAL) or vasoactive intestinal peptide (VIP), modulate secretion of gonadotropins and prolactin. The objective of the present experiment was to determine concentrations...

Monoaminergic and Peptidergic Innervation of the Intermedio-Lateral Horn of the Spinal Cord.

The European journal of neuroscience

Fuxe K, Tinner B, Bjelke B, Agnati LF, Verhofstad A, Steinbusch HG, Goldstein M, Kalia M.
PMID: 12106030
Eur J Neurosci. 1990;2(5):430-450. doi: 10.1111/j.1460-9568.1990.tb00435.x.

In the rat the monoaminergic and neuropeptidergic innervation of the sympathetic visceral nuclei of the entire thoracic spinal cord has been analysed in serial horizontal sections using immunocytochemistry. Tyrosine hydroxylase (TH), Phenyl-ethanolamine-N-methyl-transferase (PNMT), 5-hydroxytryptamine (5-HT), substance P (SP) and...

Toward Multifactorial Hypothalamic Regulation of Anterior Pituitary Hormone Secretion.

News in physiological sciences : an international journal of physiology produced jointly by the International Union of Physiological Sciences and the American Physiological Society

Crowley WR.
PMID: 11390820
News Physiol Sci. 1999 Apr;14:54-58. doi: 10.1152/physiologyonline.1999.14.2.54.

The hypothalamus regulates the secretion of anterior pituitary hormones via release of releasing hormones into the hypophysial portal vasculature. Additional neuromessengers act at the pituitary to modulate responses to the hypothalamic hormones. For example, neuropeptide Y enhances the effect...

Utilization of a novel model of food reinforced behavior involving neuropeptide Y, insulin, 2-deoxy-d-glucose and naloxone.

Behavioural pharmacology

O'Hare E, Levine AS, Semotuk MT, Tierney KJ, Shephard RA, Grace MK, Cleary J.
PMID: 11224469
Behav Pharmacol. 1996 Dec;7(8):742-753.

The cyclic-ratio schedule methodology exposes animals to an ascending followed by a descending sequence of ratio values over six consecutive cycles. The response functions, obtained by plotting response rates against reinforcement rates at each schedule value, are argued to...

Adenosine A(1) receptor: Functional receptor-receptor interactions in the brain.

Purinergic signalling

Sichardt K, Nieber K.
PMID: 18404442
Purinergic Signal. 2007 Sep;3(4):285-98. doi: 10.1007/s11302-007-9065-z. Epub 2007 Sep 05.

Over the past decade, many lines of investigation have shown that receptor-mediated signaling exhibits greater diversity than previously appreciated. Signal diversity arises from numerous factors, which include the formation of receptor dimers and interplay between different receptors. Using adenosine...
