In silico predictions of action potential propagation in doxorubicin cardiotoxicity: A parametric study using preclinical 3D magnetic resonance imaging‐based fibrotic left ventricle models

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the study's methodology and key findings. In a preclinical swine model, doxorubicin administration induced cardiotoxicity, characterized by diffuse fibrotic remodelling and altered electrical function, as assessed by magnetic resonance (MR) imaging and electrophysiological mapping.

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

α‐Synuclein oligomers slow down action potential firing and enhance dopamine release by increasing Cav2.2 currents in midbrain dopaminergic neurons

The Journal of Physiology, EarlyView.
Abstract figure legend Left: the spontaneous quantal release of dopamine (DA) occurs at very low frequency in control conditions. Right: exogenous α‐synuclein potentiates Cav2.2 currents and DA release but drastically reduces the spontaneous firing rate of substantia nigra DA neurons.

Robust activity‐dependent mitochondrial calcium dynamics at the AIS is dispensable for action potential generation

The Journal of Physiology, EarlyView.
Abstract figure legend In cortical layer (L)5 pyramidal neurons we found that mitochondria in the axon initial segment (AIS) are distributed non‐uniformly and display robust calcium (Ca2+) uptake during action potential (AP) firing. Because the AIS is the site for the initiation of APs, which are shaped by cytosolic Ca2+ levels, we hypothesized that ...
