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

Lewy bodies are surrounded by granulovacuolar degeneration bodies in dementia with Lewy bodies

Brain Pathology, EarlyView.
Here, we report Lewy bodies (LBs) to be enriched for tau‐laden granulovacuolar degeneration bodies (GVBs), suggesting a potential mechanistic interface between α‐synuclein and tau pathology in dementia with Lewy bodies (DLB). Abstract Lewy bodies (LBs), composed primarily of aggregated α‐synuclein (α‐syn), are the pathological hallmark of Lewy body ...

Activation of the PERK/eIF2α axis is a pivotal prerequisite of taxanes to cancer cell apoptosis and renders synergism to overcome paclitaxel resistance in breast cancer cells

Cancer Cell International
Background Microtubule polymerization is usually considered as the upstream of apoptotic cell death induced by taxanes, but recently published studies provide more insights into the mechanisms responsible for the antineoplastic effect of taxanes. In this

MAPK Inhibitor‐Tolerant Persister Cells in Melanoma: Mechanisms and Therapeutic Vulnerabilities

Cancer Science, EarlyView.
Melanoma response to MAPK inhibition progresses from drug‐sensitive cells to drug‐tolerant persister states, which enable survival through adaptive signaling, metabolic rewiring, and phenotypic plasticity. These persister cells serve as an intermediate reservoir from which resistant tumors ultimately emerge. ABSTRACT Though major advancements have been

Heat Stress Triggers Nuclear Invagination and Spatial Compartmentalization of Protein Metabolism

Cell Proliferation, EarlyView.
Cells adapt heat stress to shape a nuclear invagination region function as “protein metabolism hotspots”, where both protein production and degradation are enhanced. ABSTRACT Heat stress is a common challenge for cells, causing multiple types of cellular damage while triggering complex stress responses, including the highly conserved mechanism known as

ER proteostasis meets mitochondrial function: contact sites as hubs of communication and therapeutic targets

The FEBS Journal, EarlyView.
Proteostasis ensures proper protein folding, modification, and degradation, while its impairment triggers ER stress. Chronic ER stress and maladaptive UPR via the CHOP–ERO1 axis remodel ERMCs, altering calcium signaling and mitochondrial metabolism.

Eukaryotic initiation factor 2α phosphorylation is required for B-cell maturation and function in mice

Haematologica, 2011
Background The control of translation initiation is a crucial component in the regulation of gene expression. The eukaryotic initiation factor 2α (eIF2α) mediates binding of the initiator transfer-messenger-RNA to the AUG initiation codon, and thus ...

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Phosphorylation of Eukaryotic Initiation Factor-2α during Stress and Encystation in Entamoeba Species.

PLoS Pathogens, 2016
Entamoeba histolytica is an enteric pathogen responsible for amoebic dysentery and liver abscess. It alternates between the host-restricted trophozoite form and the infective environmentally-stable cyst stage. Throughout its lifecycle E.

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.
