[‚nu̇r·ō′pep‚tīd]

Other neuropeptides such as neuropeptide Y (NPY) or bradykinin may be elevated in CFS.
Neuropeptides are released from neurons through a process that -- like other secretory events -- is triggered primarily by the influx of calcium into the neuron through voltage-gated channels.
The signaling molecule corticotropin-releasing factor (CRF), a 41-amino acid neuropeptide (1) with wide distribution throughout the brain and high concentrations in cell bodies in part of the hypothalamus (i.
Neuropeptides are brain signaling molecules of fewer than 40 amino acids that can modulate neuronal function in ways that are similar, but not identical, to the actions of neurotransmitters (Burbach, 2011; Logrip et al.
In addition, the researchers examined the effect that being growth-restricted in the womb had on hypothalamic neuropeptides that control appetite when the babies were weaned.
For example, ganglia from the gastropods Aplysia and Lymnaea are known to produce neuropeptides related to growth, feeding behavior, and reproduction.
The anchor studies consider the role of peptides in appetite control, one focusing on ghrelin and other other on central and gut neuropeptides.
Different neuropeptides and neurotrophins seem to play an important role in stress-induced neurogenic inflammation and connection of nervous and immune system.
In addition to stabilizing incretins, DPP inhibitors also prolong the effects of other neuropeptides in the body including neuropeptide Y, growth hormone-releasing hormone and chemokinines.
Next time you are asked to justify your gut feelings, tell them the entire lining of the gastrointestinal tract, from the oesophagus to the large intestine, is lined with cells that contain neuropeptides and receptors.
