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.

Cellular mechanisms of radiation‐induced myocyte dysfunction: effects on calcium handling, ion channel regulation and mitochondrial energetics

The Journal of Physiology, EarlyView.
Abstract figure legend Dose‐dependent effects of radiation on cardiac electrophysiology and arrhythmia susceptibility. At low radiation doses (left), increased reactive oxygen species (ROS) initiate an ROS–Ca2+ positive feedback loop involving calcium/calmodulin‐dependent protein kinase II (CaMKII) activation, enhanced L‐type Ca2+ current (ICaL ...

Insights from animal models: Dissecting the independent roles of oxygen and nutrients in the fetal origins of cardiovascular disease

The Journal of Physiology, EarlyView.
Abstract figure legend This review utilized animal models of complicated human pregnancies that result in reduced fetal nutrient or oxygen delivery, or combined nutrient and oxygen delivery, to elucidate their independent and/or synergistic contributions to the development of high‐risk cardiac phenotypes.

A high‐fat, high‐sucrose diet exacerbates muscle and metabolic pathology and undermines glucocorticoid efficacy in dystrophin‐deficient mice

The Journal of Physiology, EarlyView.
Abstract figure legend A high‐fat, high‐sucrose diet (HFHSD) exacerbated muscle and metabolic dysregulation in mdx mice while also altering the physiological response to prednisolone (Pred) In diaphragms of control diet (CD)‐fed mdx mice, prednisolone treatment improved muscle function and reduced fibrosis, inflammatory signalling, and mitochondrial ...

SARS‐CoV‐2 targets mitochondria, exacerbating COVID‐19 pneumonia

The Journal of Physiology, EarlyView.
Abstract figure legend Following entry into airway epithelial cells (AECs), SARS‐CoV‐2 releases its single‐stranded RNA into the cytoplasm, where it is translated into viral proteins. Several of these viral proteins localize to mitochondria and interact with key mitochondrial components.
