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

open access: yesAdvanced 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

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 Y receptors in a protozoaStylonychia mytilus

open access: yesChinese 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

open access: yesAdvanced 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

open access: yesCell 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.

Astrocytic ET‐1 System Determines Microglia Phenotype Following Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
The study reveals that astrocytic ET‐1 system is solely activated by thrombin following SCI via RhoA/NF‐κB and MAPKs/NF‐κB signal pathway. The release of astrocytic ET‐1 drives microglia polarization toward M1 phenotype through YAP signaling via ETA and ETB receptors.

The Multifaceted Etiology of Mental Disorders With a Focus on Trace Elements, a Review of Recent Literature

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Mental disorders are a significant global public health concern, affecting nearly one in eight individuals worldwide. This review investigates the multifaceted etiology of mental disorders—specifically major depressive disorder (MDD), schizophrenia (SCZ), and bipolar disorder (BD)—through genetic, neurobiological, and environmental ...

High-affinity neuropeptide Y receptor antagonists. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1995
Neuropeptide Y (NPY) is one of the most abundant peptide transmitters in the mammalian brain. In the periphery it is costored and coreleased with norepinephrine from sympathetic nerve terminals. However, the physiological functions of this peptide remain unclear because of the absence of specific high-affinity receptor antagonists.

3‐Year Outcomes of Temperature‐Controlled Radiofrequency Ablation of the Posterior Nasal Nerve in Patients With Chronic Rhinitis

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Temperature‐controlled radiofrequency (TCRF) ablation of the posterior nasal nerve has been shown to improve chronic rhinitis (CR) symptoms and quality of life (QoL). This study assesses the durability of TCRF's effectiveness and safety 3 years post‐procedure in patients with perennial allergic CR and nonallergic CR.
