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

The 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 ...

The role of extracellular vesicles in cell–cell crosstalk in cardiotoxicity

The Journal of Physiology, EarlyView.
Abstract figure legend Administration of a pharmacological agent can result in off‐target cardiotoxicity which can be driven by cell–cell crosstalk between healthy and dysfunctional cardiac cells. Extracellular vesicles (EVs) are lipid bilayer structures that can move biological cargo between cells, facilitating cell–cell crosstalk.

Cellular mechanisms of radiation‐induced myocyte dysfunction: effects on calcium handling, ion channel regulation and mitochondrial energetics

The Journal of Physiology, EarlyView.
Abstract figure legend Dose‐dependent effects of radiation on cardiac electrophysiology and arrhythmia susceptibility. At low radiation doses (left), increased reactive oxygen species (ROS) initiate an ROS–Ca2+ positive feedback loop involving calcium/calmodulin‐dependent protein kinase II (CaMKII) activation, enhanced L‐type Ca2+ current (ICaL ...

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance
