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.

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.

Loss of Mfn1 but not Mfn2 enhances adipogenesis.

PLoS ONE
ObjectiveA biallelic missense mutation in mitofusin 2 (MFN2) causes multiple symmetric lipomatosis and partial lipodystrophy, implicating disruption of mitochondrial fusion or interaction with other organelles in adipocyte differentiation, growth and/or ...

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.

Aging of Skeletal Muscle: From Molecular Mechanisms to Therapeutic Interventions

MedComm, Volume 7, Issue 10, October 2026.
Skeletal muscle aging is driven by coordinated local breakdown across myofibers, stem and stromal cells, immune and vascular compartments, and neuromuscular control. These mechanisms promote mitochondrial dysfunction, inflammation, senescence, impaired regeneration, fibrosis, myosteatosis, denervation, and functional decline.

Mitochondrial Dynamics Participate in an Early Metabolic Adaptation of Glioblastoma Multiforme T98G Cells to Doxorubicin-Induced Chemotherapeutic Stress

Cells
Chemotherapy-induced metabolic reprogramming of glioblastoma multiforme (GBM) cells increases intracellular levels of reductive and energetic carriers, thereby fueling drug-relocation and retention systems and enhancing GBM drug-resistance.

Mitochondrial Fusion and Fission in Age‐Related Cardio‐Cerebral Diseases: Mechanisms and Interventions

Aging Cell, Volume 25, Issue 10, October 2026.
Mitochondrial fission‐fusion imbalance contributes to age‐related cardio‐cerebral diseases like Alzheimer's disease, Parkinson's disease, Cerebral Infarction, Arteriosclerosis, Myocardial Infarction, Cardiac valve disease, Hypertension, and Cardiomyopathy. This review summarizes its regulatory mechanisms and interventions.

Repeated Moderate and Severe Heat Exposure Has Divergent Effects on Skeletal Muscle Mitochondrial, Proteostatic and Neuromuscular Outcomes in Mice

Acta Physiologica, Volume 242, Issue 10, October 2026.
ABSTRACT Aim Repeated heat exposure may promote adaptive remodeling or cumulative tissue burden depending on thermal dose, but its graded molecular and functional consequences during recovery remain unclear. We examined whether repeated moderate (39°C) and severe (41°C) whole‐body hyperthermia produce distinct skeletal muscle trajectories involving ...

Doxorubicin and 4‐Hydroperoxycyclophosphamide Alter Mitochondrial Dynamics and miR‐34 Expression in Spermatogonia and Spermatocytes In Vitro

Basic &Clinical Pharmacology &Toxicology, Volume 139, Issue 4, October 2026.
ABSTRACT Doxorubicin (DOX) and cyclophosphamide (CP) are widely used chemotherapeutic agents with known gonadotoxic effects. Since miRNAs play a key role in the transcriptional regulation of spermatogenesis, they are suggested as biomarkers for male infertility.

Role of mitofusin 2 and mitochondrial dynamics in osteoclast differentiation and function

Os osteoclastos são macrófagos tecido-específicos com a função de reabsorção óssea. Por serem células gigantes e multinucleadas, os osteoclastos necessitam, desde a sua formação, passando pela adesão e movimentação na superfície óssea e finalmente pela ...
