Test–retest reliability of Doppler ultrasound‐based leg blood flow assessments during exercise in patients with chronic obstructive pulmonary disease

Experimental Physiology, EarlyView.
Abstract Doppler ultrasound may be used to assess leg blood flow (Q̇leg${{\dot{Q}}_{{\mathrm{leg}}}}$), but the reliability of this method remains unexplored in patients with chronic obstructive pulmonary disease (COPD), where between‐subject variability may be larger than healthy due to peripheral vascular changes.

Conformational dynamics of a nicotinic receptor neurotransmitter site

eLife
Agonists enhance receptor activity by providing net-favorable binding energy to active over resting conformations, with efficiency (η) linking binding energy to gating.

GABAB receptor‐mediated modulation of sensory neuron excitability: Roles of CaV2.2, G‐protein‐coupled inwardly rectifying potassium (GIRK) channels, and hyperpolarisation‐activated cyclic nucleotide‐gated (HCN) channels in human and mouse nociception

Experimental Physiology, EarlyView.
Abstract Chronic visceral pain is a key symptom of irritable bowel syndrome. Modulation of voltage‐gated calcium and potassium channels by G protein‐coupled receptors plays a key role in dampening nociceptive transmission. Both baclofen and the analgesic peptide α‐conotoxin Vc1.1 activate GABAB receptors (GABABR), resulting in inhibition of CaV2.2 and ...

Activation of endplate nicotinic acetylcholine receptors by agonists [PDF]

Biochemical Pharmacology, 2015
The interaction of a small molecule made in one cell with a large receptor made in another is the signature event of cell signaling. Understanding the structure and energy changes associated with agonist activation is important for engineering drugs, receptors and synapses.

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

The Journal of Physiology, EarlyView.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...

Deletion of the TRPV1 channel attenuates afferent renal nerve responses to renal artery occlusion but not elevated renal pelvic pressure

The Journal of Physiology, EarlyView.
Abstract figure legend Using wild‐type and Trpv1−/− rats, we assessed the contribution of TRPV1 channels to the activation of afferent renal nerve activity (ARNA) during renal artery occlusion, graded reductions in renal blood flow and elevated renal pelvic pressure.

Disruption of the l‐DOPA Receptor Gpr143/OA1‐Gene in Mice Creates a Unique Mixed Psychosis‐Like Phenotype

Neuropsychopharmacology Reports, Volume 46, Issue 1, March 2026.
We analyzed the behavior of GPR143 gene‐deficient mice. GPR143‐KO mice displayed a mixed psychiatric phenotype. GPR143 may play a role in mesolimbic and mesocortical functions underlying sensory gating, reward, social hierarchy, cognition, and emotional regulation. ABSTRACT GPR143, originally identified as the gene product of ocular albinism 1 (OA1), a

The Pathway to Proof‐of‐Concept for BNC210, a Negative Allosteric Modulator of the Alpha‐7 Nicotinic Acetylcholine Receptor (nAChR), for Treatment of Psychiatric Disease

Clinical Pharmacology in Drug Development, Volume 15, Issue 2, February 2026.
Abstract BNC210 is an investigational small molecule selective negative allosteric modulator of the alpha‐7 nicotinic acetylcholine receptor (α7 nAChR). It is an anxiolytic compound with a novel mechanism of action. In a series of Phase 1 clinical trials in healthy volunteers, psychometric test batteries showed that BNC210 did not cause attention ...
