Afamelanotide improves quality of life and light tolerance in Austrian erythropoietic protoporphyria patients

open access: yesJDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Background Erythropoietic protoporphyria (EPP) is a rare genetic disorder characterized by severe phototoxic reactions that occur within minutes of light exposure. In clinical studies, afamelanotide has been shown to prolong pain‐free sun exposure, improve quality of life, and reduce the frequency and severity of phototoxic reactions ...

Disruption of iron metabolism resulting from Dmt1/Slc11a2 deficiency compromises Notch protein degradation and transcriptional activation

open access: yesThe FEBS Journal, EarlyView.
Divalent metal transporter 1 (Dmt1) maintains iron homeostasis and lysosomal proteostasis required for physiological Notch receptor–ligand signaling. Dmt1 loss lowers iron storage capacity (ferritin), increasing intracellular Fe2+, driving ROS and lipid peroxidation, and leading to lysosomal/mitochondrial dysfunction.

Protective Effect of N-acetylcysteine (NAC) Administration on Prevention of Noise-Induced Hearing Loss (NIHL) in Rabbit

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Qum, 2013
Background and Objectives: Oxidative stress due to free radicals formation plays an important role in noise-induced hearing loss (NIHL). Many hypotheses have been proposed regarding the biochemical prevention of this complication.

1H NMR metabolomics and lipidomics analysis of neutrophils reveals biomarkers of ageing, inflammageing and frailty

open access: yesThe FEBS Journal, EarlyView.
Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).

The role of neutrophils in the pathophysiology of inflammatory bowel diseases

open access: yesPeriodontology 2000, EarlyView.
Abstract Objectives Inflammatory bowel disease (IBD) encompasses a spectrum of chronic disorders of the gastrointestinal tract, with a potential bidirectional relationship with periodontitis. Neutrophils are key regulators of immune‐inflammatory responses and play a major role in both diseases.

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.

P2X7 receptors promote atrial remodeling and atrial fibrillation susceptibility via reactive oxygen species‐mediated mitogen‐activated protein kinase signaling activation

open access: yesJournal of Cell Communication and Signaling, Volume 20, Issue 2, June 2026.
Abstract Atrial fibrillation (AF), the most common clinical arrhythmia, is driven by inflammatory activation and oxidative stress, though precise molecular links remain unclear. This study identifies the P2X7 receptor as a key upstream regulator orchestrating proarrhythmic atrial remodeling through reactive oxygen species (ROS)‐mediated mitogen ...

Elevated Circulating Ceramides 18:0 and 24:1 as a Risk Factor for Sarcopenia: In Vitro, Animal, and Clinical Evidence

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 3, June 2026.
ABSTRACT Background Ceramides have garnered considerable attention as pro‐aging bioactive lipids implicated in both metabolic dysfunction and musculoskeletal decline. Among these, C18:0 and C24:1 ceramides may play a role in the pathophysiology of sarcopenia, a key manifestation of age‐related deterioration.
