Understanding extracellular vesicle biology, isolation, and characterization: The theory of EV‐erything

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Extracellular vesicles (EVs), especially exosomes, are nanoparticles increasingly recognized as key regulators of intercellular communication in both physiological and pathological aspects. Despite rapid progress, inconsistencies in nomenclature, isolation, and characterization continue to restrict translational advancement.

Adenine nucleotide translocator and ATP synthase cooperate in mediating the mitochondrial permeability transition

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Both ATP synthase and adenine nucleotide translocator (ANT) play key roles in mediating the permeability transition. The contribution of ANT becomes evident in the presence of atractylate (ATR) at pH 6.5, a condition that prevents ATP synthase channel activity. At pH 7.4, this effect is minimal, suggesting a critical role for ATP

Unlocking the Door to Neuronal Woes in Alzheimer’s Disease: Aβ and Mitochondrial Permeability Transition Pore

open access: yesPharmaceuticals, 2010
Mitochondrial dysfunction occurs early in the progression of Alzheimer’s disease. Amyloid-β peptide has deleterious effects on mitochondrial function and contributes to energy failure, respiratory chain impairment, neuronal apoptosis, and generation of ...

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 ...

Study of Cyclophilin A Polymorphism in Women Patients with Cytomegalovirus Infections

open access: yesMedical Journal of Babylon
Background: Cyclophilin A (CypA) is a highly conserved protein that is expressed in a wide range of tissues and cell types and plays roles in inflammation, oxidative stress, and viral infection.

Insights into the Roles of Cyclophilin A During Influenza Virus Infection

open access: yesViruses, 2013
Cyclophilin A (CypA) is the main member of the immunophilin superfamily that has peptidyl-prolyl cis-trans isomerase activity. CypA participates in protein folding, cell signaling, inflammation and tumorigenesis. Further, CypA plays critical roles in the

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.

Voltage‐gated potassium channels mediate thyroid hormone control of skeletal muscle excitability

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Thyroid hormone (TH)‐dependent remodelling of potassium (K+) channel networks regulates skeletal muscle (SkM) excitability. Triiodothyronine (T3), locally generated from thyroxine (T4) by type 2 deiodinase (D2), binds thyroid hormone receptors (TRα/β) and modulates transcription via thyroid response elements (TREs).

Phenotypic expression of the gene‐for‐gene interaction in plant pathogenic bacteria: An implication for resistance to bacterial diseases by plants

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Plant pathogenic bacteria cause massive losses in agriculture and damage to natural plant habitats. Bacterial pathogens not only reduce crop production, but they also reduce crop quality by releasing toxins into the environment. Pathogenic bacteria that invade plant tissues must overcome the plant's defense mechanisms. Plants possess an innate

Fibroblast Activation Protein Expression Differs Between Inflamed and Fibrostenotic Inflammatory Bowel Disease

open access: yesJCC Plus, Volume 1, Issue 5, September 2026.
This study demonstrates that fibroblast activation protein expression is elevated in inflamed and fibrostenotic inflammatory bowel disease, with highest levels in fibrostenotic Crohn's disease. Cellular fibroblast activation protein predominates in inflamed tissues and localises to α‐SMA−PDPN−CD90+ stromal cells. ABSTRACT Background Intestinal fibrosis
