Demonstration of beat‐to‐beat, on‐demand ATP synthesis in ventricular myocytes reveals sex‐specific mitochondrial and cytosolic dynamics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

Intercalated disk structure, tissue heterogeneity and ion channel distribution modulate conduction and local calcium influx

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A, three‐dimensional representation of cardiac intercalated disk, reduced to a 100‐partition, computationally efficient network representation. B, ion dynamics within intercalated disk extracellular cleft space. C, rapid pacing leads to localized conduction block in tissue with regions of perturbed intercalated disk (ID ...

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 ...

The interplay between dynamic regulation of ion‐channel gating and trafficking in cardiac arrhythmogenesis

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Cardiac cellular electrophysiology is modulated by multiple factors, including temperature, extracellular K+, heart rate/pacing frequency, and drugs. These modulators can have distinct effects on ion‐channel gating and transcription/trafficking over time.
