Sedentary ageing remodels the structure–function relationships that underlie calcium signalling at super‐resolution scales in the heart

The Journal of Physiology, EarlyView.
Abstract figure legend Illustration of calcium spark function and ryanodine receptor (RyR) structure within a sedentary model of ageing. Upon sympathetic stimulation from 1 µM isoprenaline a linear response to calcium spark morphology occurred, accompanied by a biphasic progression of RyR remodelling across age.

hERG1 channels and potential therapeutics for long QT syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend Prolonged QT results from hERG1 channel dysfunction. (A) Physiological anterograde trafficking of hERG1 channels to the plasma membrane, leading to a normal electrocardiogram. (B) Prolonged QT results from the presence of fewer hERG1 channels on the plasma membrane due to decreased anterograde trafficking or reduced function due ...

Channelrhodopsin ion selectivity determines mechanisms and efficacy of optogenetic defibrillation in human atria and ventricles

The Journal of Physiology, EarlyView.
Abstract figure legend A, we used in silico models of human cardiomyocytes and microelectrode recordings on transgenic zebrafish hearts to study electrophysiology during optogenetic perturbations. Specifically, we compared effects of three distinct classes of channelrhodopsins: the cation non‐selective Chlamydomonas reinhardtii channelrhodopsin‐2 (ChR2)
