Activation of peripheral NOP receptors reduces periorbital mechanical allodynia evoked by CGRP in mice

British Journal of Pharmacology, EarlyView.
Background and Purpose Migraine is a neurovascular disorder largely mediated by calcitonin gene‐related peptide (CGRP). This study explores the role of the nociceptin/orphanin FQ (N/OFQ)–N/OFQ receptor (NOP) system in CGRP‐induced periorbital mechanical allodynia (PMA) in mice.

Profiling of HCAR1 signalling reveals Gαi/o and Gαs activation without β‐arrestin recruitment and the discovery of an allosteric agonist

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Lactate, historically viewed as a metabolic by‐product, has emerged as a signalling molecule via the G protein–coupled receptor Hydroxycarboxylic Acid Receptor 1 (HCAR1). The receptor is primarily expressed in adipocytes but also found in various other tissues.

Comprehensive transduceromic profiling of NOP receptor ligands at different Gα subunits

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose The nociceptin/orphanin FQ (N/OFQ) peptide receptor (NOP) is an opioid receptor family member with distinct pharmacology and broad therapeutic potential. NOP receptors regulate functions such as nociception, stress reactivity, reward, mood, autonomic tone, immunity and sleep/wake cycle.

Functional divergence of protein kinase A regulatory subunit Iβ variants: the importance of N3A motifs in PKA regulation

The FEBS Journal, EarlyView.
The regulatory subunit RIβ of protein kinase A occurs in two variants that differ at residue 268 (A268 versus R268). This seemingly small substitution significantly changes cAMP sensitivity, basal kinase activity, and the dynamic behavior of the regulatory domains.

Data‐Driven Feedback Identifies Focused Ultrasound Exposure Regimens for Improved Nanotheranostic Targeting of the Brain

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Machine learning models predict in real time the onset of harmful microbubble collapse during microbubble‐enhanced focused ultrasound (MB‐FUS) and enable dynamic adjustment of sonication to prevent cavitation‐induced damage. This predictive control expands the safe operating window for bloodbrain barrier opening, enhancing nanoparticle delivery and ...

In Vivo Testing of Luciferase Substrate Analogs in an Orthotopic Murine Model of Human Glioblastoma

Molecular Imaging, 2006
In vivo bioluminescent imaging using cells expressing Renilla luciferase is becoming increasingly common. Hindrances to the more widespread use of Renilla luciferase are the high autoluminescence of its natural substrate, coelenterazine, in plasma; the ...

Crystal structure of semi-synthetic obelin-v after calcium induced bioluminescence implies coelenteramine as the main reaction product

Scientific Reports, 2022
Coelenterazine-v (CTZ-v), a synthetic vinylene-bridged π-extended derivative, is able to significantly alter bioluminescence spectra of different CTZ-dependent luciferases and photoproteins by shifting them towards longer wavelengths.

Assessing Angiogenic Properties In Vitro or In Ovo of Pre‐Crosslinked Alginate‐Dialdehyde‐Gelatin Hydrogels Incorporating Boron‐Doped Mesoporous Bioactive Glass Particles

Advanced NanoBiomed Research, Volume 6, Issue 3, March 2026.
This study examines the influence of boron‐doped mesoporous bioactive glass nanoparticles (MBGN) blended in cast and 3D‐printed pre‐crosslinked alginate‐dialdehyde‐gelatin (ADA‐GEL). Addition of 0.5% and 1% MBGN did not negatively affect the viability of human umbilical vein endothelial cells (HUVECs), or the sprouting of HUVEC spheroids.
