Descrição geral

Neuropeptide Y is a regulatory molecule encoded by a gene mapped to human chromosome 7p15. Neuropeptide Y is a 36 amino acid protein with C-terminal α-amide structure. It is ubiquitously distributed in heart and brain, but at high levels in paraventricular hypothalamic nucleus, hypothalamic arcuate nucleus, suprachiasmatic nucleus, median eminence, dorsomedial, hypothalamic nucleus, paraventricular thalamic nuclei. NPY is a member of antimicrobial peptide family, which also include dermaseptins, cecropins or magainins.

Aplicação

Neuropeptide Y (NPY) human has been used:
  • to study the effect of antiepileptic effects on pentylenetetrazole (PTZ) rats.
  • as a standard in high-performance liquid chromatography (HPLC) standard and control to verify specificity of the antibodies.
  • to study the effect of NPY on motor and electroencephalographic (EEG) seizures induced by kainic acid.

Ações bioquímicas/fisiológicas

Neuropeptide Y (NPY) plays a vital role in various processes including feeding behaviour, anxiety, epilepsy, circadian, as well as rhythm memory processing, sleep, pain and drug addiction. In addition, it is also implicated in regulation of appetite, body weight and obesity. It controls central endocrine secretion and has potent vasoactive effects on the cardiovascular system. NPY is involved in the pathogenesis of atherosclerosis and coronary artery disease. NPY exhibits antimicrobial activity against Cryptococcus neoformans, Candida albicans and Arthroderma simii.
Vasoconstrictor; brain peptide that inhibits Ca2+-activated K+ channels in vascular smooth muscle. Implicated in the control of blood pressure, sexual behavior and food intake. Inhibits cholecystokinin- and secretin-stimulated pancreatic secretion.

Neuropeptide Y (NPY) is an abundant neuropeptide in the mammalian central and peripheral nervous systems. Transgenic mice overexpressing NPY in noradrenergic neurons have increased level of hepatic triglycerides, fatty acids and cholesterol, which contributed to the development of hepatosteatosis.
