The multicellular environment of the re‐entrant circuit in post‐myocardial infarction ventricular tachycardia: Beyond fibrosis

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the temporal evolution of the post‐myocardial infarction substrate leading to ventricular tachycardia. Acute ischaemic injury initiates metabolic and electrophysiological disruption, followed by progressive inflammatory, fibrotic and structural remodelling within the infarct border zone.

When NCX switches sides: Experimental and computational insights into Ca2+ regulation in the heart

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Due to its presence inside the dyadic cleft, Na+/Ca2+ exchanger (NCX) builds a functional unit together with L‐type calcium channels and ryanodine receptors in the dyadic cleft. NCX acts bidirectionally (forward and reverse mode) dependent on extracellular calcium ([Ca2+]o) and sodium ([Na+]o) concentrations and the membrane ...

Coordinated regulation of PIEZO2 by alternative splicing, post‐translational modification, membrane trafficking and protein partners

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Regulatory mechanisms such as alternative splicing, post‐translational modification, membrane trafficking, and protein interactions control channel gating, membrane abundance, and overall activity of PIEZO2. Proper regulation supports PIEZO2‐dependent proprioceptive, somatosensory, nociceptive, pruriceptive and interoceptive ...

Drafting the calmodulation playbook: Emerging structural insights into transient receptor potential channel regulation by calmodulin

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Calmodulin (CaM) is a ubiquitous calcium (Ca2+) sensor that translates intracellular Ca2+ signals into modulation of hundreds of effector proteins including ion channels. CaM is increasingly recognized as a key regulator of the transient receptor potential (TRP) channel family, yet the underlying ‘calmodulation playbook’ is only ...

Intracellular mechanosensation in intestinal smooth muscle: Piezo1 complexes amplify signalling beyond the surface

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Mechanosensation is not confined to the cell surface. In intestinal smooth muscle Piezo1 is predominantly intracellular (86%), where it forms a nanoscale (<40 nm) complex at the sarcoplasmic reticulum (SR)–plasma membrane junction. Within this sensor–amplifier–effector axis intra‐Piezo1 is the sensor that detects force at the SR,

N‐Arachidonoyl‐phosphatidylethanolamide phospholipase D activation by muscarinic receptors

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Activating muscarinic M3 receptors activates Gq‐pathway signalling, including the activation of phospholipase C (PLC) and release of calcium from internal stores as shown in the upper panel. It remains unclear whether the calcium acts on N‐arachidonoyl‐phosphatidylethanolamide phospholipase D (NAPE‐PLD) itself or upstream at N ...

Deep Learning Enables Identification of Antimicrobial Peptides Through Mechanochromic Fingerprints

open access: yesAngewandte Chemie, Volume 138, Issue 37, 7 September 2026.
We demonstrate a new platform for antimicrobial peptide identification by combining polydiacetylene, hyperspectral imaging, and deep learning. The trained model classifies distinct spectral fingerprints into 14 peptide classes with 96.79% accuracy, revealing previously hidden molecular information beyond conventional colorimetric sensing.
