Electrodiffusion in cardiac intercalated disc nanostructures alters cell–cell action potential transmission via ephaptic coupling: A model study

The Journal of Physiology, EarlyView.
Abstract figure legend Ephaptic phenomena in a high‐resolution model of the cardiac intercalated disc. Meshed representation of a tortuous intercalated disc that was generated based on electron and super‐resolution microscopy data. Na+ channels (red) and gap junctions (green) are heterogeneously distributed, with additional regions of reduced ion ...

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

The 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

The 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 ...
