Vasoactive intestinal polypeptide and pituitary adenylate cyclase activating polypeptide : effects on insulin release in isolated mouse islets in relation to metabolic status and age

open access: yes, 2006
Obesity and development of the metabolic syndrome is related to an increased parasympathetic tone and hyperinsulinemia. We have now studied the effects of age and metabolic status on glucose-induced insulin release stimulated by the neuropeptides ...

Epigenetic control of cancer by neuropeptides [PDF]

open access: yes, 2016
Neuropeptides act as neurohormones, neurotransmitters and/or neuromodulators. Neuropeptides maintain physiological homeostasis and are paramount in molecular mechanisms of disease progression and regulation, including in cancer.

Brain cholecystokin octopeptide (CCK-8) concentrations: Effect of tryptophan and other serotonergic agents

open access: yes, 1994
The effects of 1-week drug treatment on the brain contents of neuropeptides were investigated. The cholecystokinin (CCK) concentrations in the hypothalamus were significantly decreased by tryptophan treatment but not by imipramine and cyproheptadine ...

Insect Mating Behaviors: A Review of the Regulatory Role of Neuropeptides

open access: yesInsects
Insect mating behaviors are complex, diverse, and primarily regulated by neuropeptides and their receptors. Neuropeptides are peptide signaling molecules mainly secreted by insects’ central nervous system (CNS) to reach target organs.

Neuropeptides in platyhelminths

open access: yesParasitology, 1991
The neuropeptide story began in 1928 with the description by Ernst Scharrer of gland-like nerve cells in the hypothalamus of the minnow,Phoxinus laevis.Because these nerve cells were overwhelmingly specialized for secretory activity, overshadowing other neuronal properties, Scharrer termed them ‘neurosecretory neurons’.

The neuropeptide concept

open access: yesMaturitas, 1984
In 1960/61 it was found that the release of adrenocorticotrophic hormone (ACTH) in response to emotional, but not to somatic or systemic stress, was diminished in rats in which the vasopressin storage organ, the posterior intermediate lobe of the rat pituitary, had been surgically removed [1,2].

Neuropeptides, Stress-Related

open access: yes, 2007
This article discusses neuropeptides that are involved in the regulation of stress responses and released as effector molecules during stress. The neuropeptides discussed include corticotropin releasing hormone, arginine vasopressin, the opioids ...
