Temperature dependence of HCN channel kinetics: A systematic comparison across mammalian isoforms and species

open access: yesExperimental Physiology, EarlyView.
Abstract Hyperpolarization‐activated, cyclic nucleotide‐gated (HCN) channels are important regulators of cardiac pacemaking and neuronal excitability, yet their temperature dependence has not been compared systematically across mammalian isoforms and species in standardized experimental conditions. Here, we performed a standardized electrophysiological

Computational modelling of cardiac fibroblast signalling reveals a key role for Ca2+ in driving atrial fibrillation‐associated fibrosis

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A pre‐existing fibroblast signalling model was enhanced by integrating atrial‐specific components and reactions linked to atrial fibrosis and atrial fibrillation (AF). The analysis highlights the central role of Ca2⁺ signalling in driving profibrotic responses to AF‐relevant stimuli, angiotensin‐II and transforming growth factor ...

Human‐derived cardiac‐neural microtissues reveal catecholaminergic polymorphic ventricular tachycardia is also a disease of the sympathetic neuron

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...

An age‐associated decline in the role of the sarcoplasmic reticulum and associated calcium‐handling proteins sets the pace for sinoatrial node function

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Stable, responsive pacemaking in the sinoatrial node is driven by the activity of the funny current (membrane clock), interplay of calcium cycling and release from the sarcoendoplasmic reticulum with depolarising sodium‐calcium exchange current (calcium clock). With increasing age, key proteins associated with calcium cycling are

The Maintenance of Dysmyelinated Small‐Diameter Axons by 14‐3‐3s in the Central Nervous System

open access: yesGlia, Volume 74, Issue 11, November 2026.
Dysmyelinated small‐diameter axons are maintained in teneurin‐4 deficient mice at the age of 1 year, while axonal damage is observed. 14‐3‐3s are highly expressed and suppress the progression of the damage in these axons. ABSTRACT In the central nervous system, myelin formed around nerve axons by oligodendrocyte enables efficient conduction of action ...

Lung‐Cardiovascular Interactions and Derangements in ARDS

open access: yesComprehensive Physiology, Volume 16, Issue 5, October 2026.
This review proposes an anatomical near‐ and far‐field framework for lung‐cardiovascular interactions in ARDS. Grounded in pathological and biological studies, the evidence spans pulmonary vascular, right ventricular, and systemic endothelial derangements and reviews available evidence for targeted therapies.

1H HR‐MAS NMR Metabolomics in Combination With Transcriptomic Correlation Provides New Insights Into Metabolic Heterogeneity Across Breast Cancer Immunohistochemical Subtypes

open access: yesNMR in Biomedicine, Volume 39, Issue 10, October 2026.
Metabolomic profiling of breast cancer tissue using 1H HR‐MAS NMR spectroscopy and LCModel‐based quantitative analysis revealed metabolite differences associated with immunohistochemical subtypes, and subsequent metabolomics–transcriptomics integration linked these subtype‐dependent metabolic signatures to pathways in choline metabolism, one‐carbon ...

ATP Release and Purinergic Signaling Potentiate β‐Adrenergic Effects on Brown Adipocytes

open access: yesActa Physiologica, Volume 242, Issue 10, October 2026.
ABSTRACT Aim Brown adipose tissue (BAT) specializes in energy consumption and thermogenesis in response to cold stress. Brown adipocytes (BA) express purinergic receptors, yet little is known about the source of extracellular ATP and the role of purinergic signaling, and the potential interaction with β‐adrenergic signaling.
