Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Fn14 signalling participates in pristane‐induced murine lupus through exacerbating oxidative stress

British Journal of Pharmacology, EarlyView.
Background and Purpose Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by oxidative stress and immune dysregulation. Fibroblast growth factor‐inducible 14 (Fn14) has been implicated in tissue injury, but its specific role in SLE pathogenesis remains unclear.

Maximum likelihood tree and schematic diagrams of heme oxygenase proteins.

, 2018
Maximum likelihood (ML) tree based on an alignment of 510 heme oxygenase amino acid sequences from 1,678 taxa. Red algal heme oxygenases had three isotypes of heme oxygenase; HMOX1, HMOX2, and pbsA.

Gasdermin‐Mediated Pyroptosis: Novel Strategies Against Colorectal Cancer

Cancer Science, EarlyView.
Pyroptosis is a double‐edged sword in colorectal cancer (CRC): chronic low‐grade pyroptosis promotes tumor progression, whereas acute induction of pyroptosis in cancer cells triggers antitumor immunity and enhances therapeutic response. Targeting gasdermin‐mediated pyroptosis represents a promising strategy for CRC treatment.

Targeting PCSK9 in Vascular Smooth Muscle Cells: An Effective Strategy to Suppress Ferroptosis and Attenuate Abdominal Aortic Aneurysm Progression

Cell Proliferation, EarlyView.
PCSK9 aggravates AAA by promoting ferroptosis in VSMCs. In the pathological AAA environment, PCSK9 upregulation triggers ferritinophagy‐dependent degradation of FTH1, leading to Fe2+ release, triggering lipid peroxidation and ferroptosis, exacerbating AAA.

The heme oxygenase(s)-phytochrome system of Pseudomonas aeruginosa

, 2004
For many pathogenic bacteria like Pseudomonas aeruginosa heme is an essential source of iron. After uptake, the heme molecule is degraded by heme oxygenases to yield iron, carbon monoxide, and biliverdin.

Inflammatory Cytokines Impair Glucagon Expression and Secretion in Pancreatic α‐Cells

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Insulin resistance and obesity‐associated inflammation are key drivers in the pathogenesis of Type 2 diabetes mellitus (T2DM). Whilst inflammatory cytokines are well known to impair β‐cell function, their impact on pancreatic α‐cells and glucagon (GCG) regulation remains poorly understood. In this study, we investigated the effects of the

Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

The FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...

GCN2 in proteostasis: structural logic, signalling networks and disease

The FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.
