neuropeptide

[‚nu̇r·ō′pep‚tīd]
(neuroscience)
A polypeptide released by axons at the synapse; it may act as a neurotransmitter and have a direct effect on synapse function or as a neuromodulator, having a long-term effect on postsynaptic neurons.

"New research shows that CGRP, which is a neuropeptide, has a central role in the pathophysiology of migraine," says Dr Karoly Zoltan Vadasdi, Neurology Specialist, Canadian Specialist Hospital.
To date, many appetite-regulating peptides have been identified in fish including cocaine, leptin (Zhang et al., 1994), ghrelin (GRLN) (Zhou et al., 2016), peptide YY (PYY) (Holzer et al., 2012), neuropeptide Y (NPY) (Wei et al., 2014; Volkoff, 2016).
In this regard, we hypothesized that NPS, which is a neuropeptide associated with neuro-vegetative and neuroendocrinological pathways, could also be associated with GAD, an anxiety disorder that presents somatic symptoms.
Another neuropeptide is galanin, a 29-amino acid peptide that was discovered in 1983 in the porcine intestine as an orexigenic neuropeptide; it is mainly synthesized in the central and peripheral nervous systems and gastrointestinal tract.
"It confirms that the Renuva Generator Powder which we've been selling since 2003, produces a significant increase in the release of human growth hormone while it promotes both a healthy endocrine and neuropeptide system.
Neuropeptide S: anatomy, pharmacology, genetics and physiological functions.
Researchers pinpointed a particular neuropeptide associated with transmitting itch signals in mice with atopic dermatitis.
The study also shows that these chemicals--small proteins called neuropeptides that regulate neural activity--each control a different sleep behavior, such as the suppression of feeding or movement.
However, in the new study published in the journal Cell, the team found that chronic isolation leads to an increase in Tac2 gene expression and the production of a neuropeptide called neurokinin B (NkB) throughout the brain.
Tachykinin is a neuropeptide that is released when certain neurons are activated.
"Successful mating is naturally rewarding to male flies and increases the levels of a small peptide in the brain called neuropeptide F," said Dr.
The study was published in the journal Current Biology and scientists explained how they engineered the flies so that the light triggered neurons that released a neuropeptide called corazonin.
