neuropeptide

[‚nu̇r·ō′pep‚tīd]

Neuropeptides, meanwhile, work with DMAE to create a smooth skin texture that softens the look of fine lines in the Perricone MD Neuropeptide Face Activator.
A team of researchers led by JosEa Lemos from the University of Massachusetts Medical School examined the mechanisms at play during secretion of vasopressin from nerve terminals in the posterior pituitary gland, which releases the neuropeptide into the blood so that it can make its way to the kidney and regulate water retention.
The neuropeptides concerned with feeding behavior are involved in this complex controlling system, of which the anorexigenic neuropeptide like proopiomelanocortin (POMC) and orexigenic neuropeptide like Neuropeptide Y (NPY) play important roles in the regulation of food intake and energy balance (Bazhan and Zelena, 2013).
Entomologist Man-Yeon Choi and chemist Robert Vander Meer, in the center's Imported Fire Ant and Household Insect Research Unit, have demonstrated for the first time that a neuropeptide hormone, originally discovered in moths, activates the production of trail pheromones.
Neuropeptide Y (NPY) is widely expressed in the central nervous system where it is involved in various functions including the regulation of circadian rhythms, blood pressure, feeding behaviour, anxiety, memory processing, and cognition [9].
