Bidirectional Interaction Between the Brain and Bone in Traumatic Brain Injury

Advanced Science, EarlyView.
Traumatic brain injury (TBI) disrupts the blood–brain barrier and activates neuroimmune responses, causing metabolic disturbances and long‐term bone mass loss. Concurrent fractures accelerate healing and enhance osteogenesis but disrupt regulatory mechanisms, leading to altered bone dynamics and exacerbating neuroinflammation, complicating recovery ...

Structural basis of neuropeptide Y signaling through Y1 and Y2 receptors

MedComm
Neuropeptide Y (NPY), a 36‐amino‐acid peptide, functions as a neurotransmitter in both the central and peripheral nervous systems by activating the NPY receptor subfamily.

The Lymnaea Cardioexcitatory Peptide (LyCEP) Receptor: A G-Protein–Coupled Receptor for a Novel Member of the RFamide Neuropeptide Family [PDF]

, 1998
A novel G-protein–coupled receptor (GRL106) resembling neuropeptide Y and tachykinin receptors was cloned from the molluscLymnaea stagnalis. Application of a peptide extract from the Lymnaea brain to Xenopus oocytes expressing GRL106 activated a calcium ...

An opioid-like system regulating feeding behavior in C. elegans [PDF]

, 2015
Neuropeptides are essential for the regulation of appetite. Here we show that neuropeptides could regulate feeding in mutants that lack neurotransmission from the motor neurons that stimulate feeding muscles. We identified nlp-24 by an RNAi screen of 115

Oxytocin Reduces Subjective Fear in Naturalistic Social Contexts via Enhancing Top‐Down Middle Cingulate Amygdala Regulation and Brain‐Wide Fear Representations

Advanced Science, EarlyView.
This double‐blind, placebo‐controlled study demonstrates that intranasal oxytocin reduces subjective fear in immersive, naturalistic social (but not non‐social) contexts. Concomitant fMRI reveals that oxytocin enhances middle cingulate activity and amygdala connectivity while it modulates network‐level connectivity and attenuates reactivity of a brain ...

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

Neurobiology 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.

N-Arachidonoyl Dopamine Modulates Acute Systemic Inflammation via Nonhematopoietic TRPV1. [PDF]

, 2017
N-Arachidonoyl dopamine (NADA) is an endogenous lipid that potently activates the transient receptor potential vanilloid 1 (TRPV1), which mediates pain and thermosensation. NADA is also an agonist of cannabinoid receptors 1 and 2.

Neuropeptide Y receptors in a protozoaStylonychia mytilus

Chinese Science Bulletin, 1998
Radio ligand binding assays(RLBA) were used to study neuropeptide Y (NPY) receptors in a protozoaStylonychia mytilus. The experimental results showed that 2–3 × 103/mLStylonychia cells incubated in Pringsheim solution which contained3H-NPY could specifically bind3H-NPY and concoraitantly present saturable characteristic.

CGRP‐Loaded ROS‐Responsive Hydrogel Restores Neuro‐Angiogenic Signaling to Promote Bone Regeneration in Diabetes‐Associated Periodontitis

Advanced Science, EarlyView.
This study shows that diabetes damages sensory nerve fibers, especially CGRP‐positive ones, in the periodontium and disrupts autophagy in trigeminal ganglion neurons, affecting bone homeostasis by inhibiting type H vessel formation. To address this, CGRP@PVA/tsPBA hydrogels are developed to release CGRP in response to ROS, which binds to endothelial ...

Pharmacological and functional similarities of the human neuropeptide Y system in C. elegans challenges phylogenetic views on the FLP/NPR system

Cell Communication and Signaling, 2019
Background The neuropeptide Y system affects various processes, among others food intake, and is frequently discussed in the context of targeting obesity. Studies in model organisms are indispensable to enable molecular studies in a physiological context.
