Neuropeptides such as neuropeptide Y (NPY) have long been proposed to play a role in the pathogenesis of inflammatory diseases. NPY is a 36 amino acid neuropeptide which participates in the regulation of a large number of physiological and pathophysiological processes in the cardiorespiratory system, immune system, nervous system and endocrine system ...

NPY receptors and opioidergic system are involved in NPY-induced feeding in goldfish
Peptides, 2000The present study evaluated the effects of both intraperitoneal (i.p. ) and intracerebroventricular administration of selective Y(1) [(Leu(31), Pro(34))-NPY] and Y(2) [(Pro(13), Tyr(36))-NPY (13-36)] receptor agonists on food intake in satiated goldfish.

Parasites flicking the NPY gene on the host's switchboard: why NPY?
The FASEB Journal, 1999ABSTRACT It was investigated whether up‐regulation of the NPY gene by the schistosome Trichobilharzia ocellata in its snail host Lymnaea stagnalis redirects the host's energy flows.

The role of NPY in learning and memory
Neuropeptides, 2016High levels of NPY expression in brain regions important for learning and memory together with its neuromodulatory and neurotrophic effects suggest a regulatory role for NPY in memory processes. Therefore it is not surprising that an increasing number of studies have provided evidence for NPY acting as a modulator of neuroplasticity, neurotransmission,

Neuropeptide Y (Npy) and Npy Receptors in The Rat Pineal Gland
2005NPY is considered to play an important role in pineal function, because it is co-stored with the dominant pineal transmitter noradrenaline. However, little evidence from the literature suggests that NPY alone is a strong regulator of melatonin synthesis or secretion and it is therefore more likely that NPY modulates noradrenergic neurotransmission in ...

Intake inhibition by NPY and CCK-8: A challenge of the notion of NPY as an “Orexigen”
Behavioural Brain Research, 2005We tested the hypothesis that neuropeptide Y (NPY) interacts with cholecystokinin octapeptide (CCK-8) in inhibition of intake of an intraorally infused solution of sucrose, a test of consummatory ingestive behavior. Both intracerebroventricular infusion of NPY (10 microg) and intraperitoneal injection of CCK-8 (0.5 micro/kg) reduced the intake of a 1M ...

The intracellular mobility of NPY and a putative mitochondrial form of NPY in neuronal cells
Neuroscience Letters, 2009Preproneuropeptide Y is a precursor peptide to mature neuropeptide Y (NPY), which is a universally expressed peptide in the central and peripheral nervous system. NPY is normally routed to endoplasmic reticulum and secretory vesicles in cells, which secrete NPY.

Spinal mechanisms of NPY analgesia
Peptides, 2007We review previously published data, and present some new data, indicating that spinal application of neuropeptide Y (NPY) reduces behavioral and neurophysiological signs of acute and chronic pain. In models of acute pain, early behavioral studies showed that spinal (intrathecal) administration of NPY and Y2 receptor agonists decrease thermal ...

Distribution of NPY receptors in the hypothalamus
Neuropeptides, 2004Neuropeptide Y (NPY) neurons abundantly innervate the hypothalamus, where NPY is involved in the regulation and integration of a broad range of homeostatic functions. In order to understand NPY-mediated behavioral, autonomic and neuroendocrine effects, it is important to characterize in detail the distribution of the hypothalamic NPY receptors. In this

NPY regulation of bone remodelling
Neuropeptides, 2009Neuropeptide Y (NPY), a classic neuronal regulator of energy homeostasis, is now also known to be involved in the control of bone homeostasis. Of the five known Y receptors through which the NPY family of ligands signals, the Y1 and Y2 receptors have so far been implicated in the control of osteoblast activity and thus bone formation. Analysis of brain
