Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).

Fetal glucose availability: a key regulator of the metabolic, hormonal and contractility profiles of the fetal sheep heart

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend To investigate the role of glucose availability in fetal left ventricle (LV) development, this study assessed whether maternal late gestation undernutrition (LGUN; 50% of Control diet) induced alterations in the contractility, metabolic, and hormonal profile can be ameliorated in LGUN fetuses receiving glucose infusion (LGUN+G ...

Human placental exposure to pollutant nanoparticles: uptake, translocation and functional impact

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to pollutant nanoparticles has been increasingly investigated due to concerns about their potential effects on placental function and pregnancy outcomes. Maternal inhalation of pollutant nanoparticles can result in a pro‐inflammatory response; particles can also translocate across the alveolus epithelial barrier

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

open access: yesThe 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.

Integrating Lateral Super‐Resolution and Axial Progression Reveals Distinct Clathrin Pit Formation Pathways

open access: yesTraffic, Volume 27, Issue 3, September 2026.
Variable‐angle total internal reflection fluorescence structured illumination microscopy (vaTIRF‐SIM) links nanoscale lateral organization with axial progression during clathrin‐mediated endocytosis. Super‐resolved TIRF‐SIM images resolve the lateral architecture of AP2‐labeled clathrin coats, while corresponding Z‐index maps report relative axial ...

A Quarter Century of EHD Protein Research: From Endosomal Recycling to Ciliopathies

open access: yesTraffic, Volume 27, Issue 3, September 2026.
Human EHD protein subcellular localization. ABSTRACT Eps15 homology domain‐containing proteins comprise a conserved family of membrane‐remodeling ATPases that regulate endocytic trafficking, membrane fission, receptor recycling, primary ciliogenesis and membrane dynamics across eukaryotes. Since the initial identification of EHD1 and its Caenorhabditis

Raptor and Drp1 Function Synthetically to Control Hypoxic Death and the Mitochondrial Network in Caenorhabditis elegans

open access: yesThe FASEB Journal, Volume 40, Issue 13, 15 July 2026.
Hypoxia results in fragmented mitochondria. Whether this fragmentation promotes or prevents cell death is unresolved. Caenorhabditis elegans mutants defective in mitochondrial fission and fusion coupled with a hypoxia resistant Raptor mutant demonstrated that hypoxia‐induced mitochondrial fragmentation occurs without an intact fission machinery and ...
