Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Potential health benefits of cold‐water immersion: the central role of PGC‐1α

The Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

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

The 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.

Human‐derived cardiac‐neural microtissues reveal catecholaminergic polymorphic ventricular tachycardia is also a disease of the sympathetic neuron

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...
