Unusually persistent Gαi-signaling of the neuropeptide Y2 receptor depletes cellular Gi/o pools and leads to a Gi-refractory state

open access: yesCell Communication and Signaling, 2020
Background A sensitive balance between receptor activation and desensitization is crucial for cellular homeostasis. Like many other GPCR, the human neuropeptide Y2 receptor (hY2R) undergoes ligand dependent activation and internalization into ...

PET Imaging of the Neuropeptide Y System: A Systematic Review

open access: yesMolecules, 2022
Neuropeptide Y (NPY) is a vastly studied biological peptide with numerous physiological functions that activate the NPY receptor family (Y1, Y2, Y4 and Y5).

Ligands of the neuropeptide Y Y2 receptor [PDF]

open access: yesBioorganic & Medicinal Chemistry Letters, 2014
Neuropeptide Y (NPY) is one of the most abundant neuropeptides in the mammalian brain and exerts a variety of physiological processes in humans via four different receptor subtypes Y1, Y2, Y4 and Y5. Y2 receptor is the most abundant Y subtype receptor in the central nervous system and implicated with food intake, bone formation, affective disorders ...

Echinoderms provide missing link in the evolution of PrRP/sNPF-type neuropeptide signalling

open access: yeseLife, 2020
Neuropeptide signalling systems comprising peptide ligands and cognate receptors are evolutionarily ancient regulators of physiology and behaviour.

Structural basis for ligand recognition of the neuropeptide Y Y2 receptor

open access: yesNature Communications, 2021
The human neuropeptide Y receptor Y2 (Y2R) is a drug target for the treatment of obesity and anxiety. Crystal structure of Y2R bound to a selective antagonist and accompanying mutagenesis provide insights into ligand recognition and subtype specificity ...

Characterization of vascular neuropeptide Y receptors [PDF]

open access: yesBritish Journal of Pharmacology, 1992
In the present study we compared neuropeptide Y (NPY) and NPY‐related analogues for their ability to activate or bind to vascular NPY receptors in four experimental set‐ups. Previous results have suggested the existence of different receptor subtypes, Y1 receptors requiring full‐length NPY (1–36) or [Pro34]‐NPY, and Y2 receptors recognizing also N ...

Neuropeptide Y receptor in the rat brain [PDF]

open access: yesEuropean Journal of Biochemistry, 1984
The specific binding of the chloramine-T iodinated neuropeptide Y (125I-NPY) to membranes from rat cerebral cortex was investigated using equilibrium binding and kinetic methods. The equilibrium binding of 125I-NPY at 37 degrees C was characterized by a Kd value of 0.38 nM. The receptor densities in the cerebral cortex, hypothalamus and cerebellum were

Combined gene overexpression of neuropeptide Y and its receptor Y5 in the hippocampus suppresses seizures

open access: yesNeurobiology of Disease, 2012
We recently demonstrated that recombinant adeno-associated viral vector-induced hippocampal overexpression of neuropeptide Y receptor, Y2, exerts a seizure-suppressant effect in kindling and kainate-induced models of epilepsy in rats.

Neuropeptide System Regulation of Prefrontal Cortex Circuitry: Implications for Neuropsychiatric Disorders

open access: yesFrontiers in Neural Circuits, 2022
Neuropeptides, a diverse class of signaling molecules in the nervous system, modulate various biological effects including membrane excitability, synaptic transmission and synaptogenesis, gene expression, and glial cell architecture and function. To date,

A Promising Therapeutic Target for Metabolic Diseases: Neuropeptide Y Receptors in Humans

open access: yesCellular Physiology and Biochemistry, 2017
Human neuropeptide Y (hNPY) is one of the most widely expressed neurotransmitters in the human central and peripheral nervous systems. It consists of 36 highly conserved amino acid residues, and was first isolated from the porcine hypothalamus in 1982 ...
