Neuropeptides function through G protein-coupled receptors (GPCRs) with high specificity, implying a significant degree of neuropeptide-GPCR coevolution. However, potential neuropeptide signaling systems in non-chordates are relatively elusive.

Investigations on neuropeptide Y and histamine receptors by fluorescence-based and radiochemical methods [PDF]
In the last three decades, a large amount of experimental data (for example Förster resonance energy transfer (FRET) at fluorescently labelled receptors) supported the hypothesis of the dimerization of G-protein-coupled receptors (GPCR), including ...

The reproductive hormones that trigger oocyte meiotic maturation and release from the ovary vary greatly between animal species. Identification of receptors for these maturation-inducing hormones (MIHs) and understanding how they initiate the largely ...

Y1 and Y2 receptors for neuropeptide Y [PDF]
By using monoiodinated radioligands of both intact neuropeptide Y (NPY) and of a long C‐terminal fragment, NPY13–36, two subtypes of binding sites, which differ in affinity and specificity, have been characterized. The Y1 type of binding site, characterized on a human neuroblastoma cell line, MC‐IXC, and a rat pheochromocytoma cell line, PC‐12, binds ...

Phylogenetic investigation of peptide hormone and growth factor receptors in five dipteran genomes
Peptide hormones and growth factors bind to membrane receptors and regulate a myriad of processes in insects and other metazoans. The evolutionary relationships among characterized and un-characterized (orphan) receptors can provide insights into ...

Functional and genetic characterization of neuropeptide Y-like receptors in Aedes aegypti. [PDF]
BACKGROUND:Female Aedes aegypti mosquitoes are the principal vector for dengue fever, causing 50-100 million infections per year, transmitted between human and mosquito by blood feeding. Ae.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

The neurokinin 1 receptor exists as full‐length (NK1L) and C‐terminally truncated (NK1S) splice variants. We show that NK1S heterodimerizes with NK1L, impairing Gαq coupling and Ca2+ mobilization while enhancing β‐arrestin1 recruitment. NK1S suppresses substance P‐driven gene expression and cell migration, revealing NK1S as an endogenous biased ...

Impact of Orexin-A Treatment on Food Intake, Energy Metabolism and Body Weight in Mice. [PDF]
Orexin-A and -B are hypothalamic neuropeptides of 33 and 28-amino acids, which regulate many homeostatic systems including sleep/wakefulness states, energy balance, energy homeostasis, reward seeking and drug addiction.

The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study
ABSTRACT Objective High‐altitude headache (HAH) is a common neurological condition associated with rapid ascent to high altitude. The pathophysiological mechanisms underlying HAH remain incompletely understood. Calcitonin gene‐related peptide (CGRP), a neuropeptide implicated in migraine pathophysiology, may play a key role in the pathophysiology of ...
