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 ...

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.

Hypoxia‐induced vulnerability of the somatosensory nervous system

The Journal of Physiology, EarlyView.
Abstract figure legend Sensory neurons are highly energy dependent and rely on sufficient oxygen availability to maintain metabolic stability and effective neurocommunication. Within the somatosensory system, even modest reductions in tissue oxygen tension impair neuronal respiration, forcing a shift toward less efficient metabolic pathways that ...

Restoration of neuromuscular function by mitochondrial transplantation in injured mouse skeletal muscle

The Journal of Physiology, EarlyView.
Abstract figure legend Mice received chemical injury (cardiotoxin) in the tibialis anterior muscle of one limb, and the contralateral muscle was injected with phosphate‐buffered saline (PBS) as a sham control. Mice then received PBS or mitochondria suspended in PBS into the tail vein.

Mitochondrial permeability transition in skeletal muscle phenocopies muscle alterations seen in cancer cachexia and other wasting conditions

The Journal of Physiology, EarlyView.
Abstract figure legend Skeletal muscle wasting conditions are characterized by muscle fibre atrophy, mitochondrial respiratory dysfunction, mitochondrial depletion and fragmentation of acetylcholine receptor (AChR) cluster at the neuromuscular junction.

Baicalin Alleviates Lactational Heat‐Stress‐Induced Hepatic Mitochondrial Dysfunction via Sirt3‐Dependent Deacetylation of NDUFS1

Food Frontiers, Volume 7, Issue 6, November 2026.
This study reveals that lactational HS suppresses Sirt3 activity, leading to hyperacetylation of the complex I subunit NDUFS1, and excessive mitochondrial ROS production, whereas BAI, a nature food‐derived bioactive compound, alleviates lactational HS‐induced hepatic mitochondrial injury by activating the Sirt3–NDUFS1 axis to deacetylate mitochondrial ...
