Signal transducer and activator of transcription 2 deficiency is a novel disorder of mitochondrial fission [PDF]

, 2015
Defects of mitochondrial dynamics are emerging causes of neurological disease. In two children presenting with severe neurological deterioration following viral infection we identified a novel homozygous STAT2 mutation, c.1836C4A (p.Cys612Ter), using ...

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

The 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 ...

Restoring mitofusin balance prevents axonal degeneration in a Charcot-Marie-Tooth type 2A model [PDF]

, 2019
Mitofusin-2 (MFN2) is a mitochondrial outer-membrane protein that plays a pivotal role in mitochondrial dynamics in most tissues, yet mutations in MFN2, which cause Charcot-Marie-Tooth disease type 2A (CMT2A), primarily affect the nervous system.

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. (

AIBP: A New Safeguard against Glaucomatous Neuroinflammation

Cells
Glaucoma is a group of ocular diseases that cause irreversible blindness. It is characterized by multifactorial degeneration of the optic nerve axons and retinal ganglion cells (RGCs), resulting in the loss of vision.

Mitofusin 2 Inhibits Angiotensin II-Induced Myocardial Hypertrophy

Journal of Cardiovascular Pharmacology and Therapeutics, 2010
Background and Objectives: Myocardial hypertrophy is a common clinical finding leading to heart failure and sudden death. Mitofusin 2 (Mfn2), a hyperplasia suppressor protein, is downregulated in hypertrophic heart. This study examined the role of Mfn2 in myocardial hypertrophy and its potential signal pathway. Methods and Results: In in vitro studies,

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.

Inhibition of cAMP/PKA Pathway Protects Optic Nerve Head Astrocytes against Oxidative Stress by Akt/Bax Phosphorylation-Mediated Mfn1/2 Oligomerization. [PDF]

, 2019
Glaucoma is characterized by a progressive optic nerve degeneration and retinal ganglion cell loss, but the underlying biological basis for the accompanying neurodegeneration is not known.

A Review of Vagus Nerve Stimulation for Disease: Comprehensive Theory and Evidence for Mechanisms of Action

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Vagus nerve stimulation (VNS) effects span central and peripheral organ systems through diverse mechanistic pathways. This comprehensive review provides a unified synthesis of these mechanisms across neurological, cardiovascular, immunological, metabolic, and gastrointestinal domains, filling a critical gap and serving as a foundational resource for ...
