Air Pollution Quinones Impair Intestinal Barrier Integrity and Endoplasmic Reticulum in Differentiated Caco‐2 Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Particulate matter (PM) is a major global health threat, linked to millions of deaths annually. Beyond inhalation, PM components reach the gastrointestinal tract through the mucociliary escalator or contaminated food and water. Among PM's organic fraction, redox‐active quinones such as 1,2‐naphthoquinone (NQ) and 9,10‐phenanthrenequinone (PQ ...

Desmosome assembly and dynamics [PDF]

Trends in Cell Biology, 2013
Desmosomes are intercellular junctions that anchor intermediate filaments (IFs) to the plasma membrane, forming a supracellular scaffold that provides mechanical resilience to tissues. This anchoring function is accomplished by specialized members of the cadherin family and associated cytoskeletal linking proteins, which together form a highly ...

New insights into desmosome regulation and pemphigus blistering as a desmosome-remodeling disease

Kaohsiung Journal of Medical Sciences, 2013
Desmosomes in keratinocytes are the most important intercellular adhering junctions that provide structural strength for the epidermis. These junctions are connected directly with desmosomal cadherin proteins.

COL1A1+ Epithelial Cells Orchestrate VEGFA‐VEGFR Signaling in Endometritis Revealed by Single‐Cell Analysis

Journal of Clinical Laboratory Analysis, EarlyView.
Single‐cell RNA‐seq of normal and endometritis endometrium shows reduced epithelial cells and fate divergence toward ferroptosis or ribosome/antigen‐presentation programs. COL1A1+ epithelial cells act as an AP‐1–driven hub that enhances VEGFA–VEGFR signaling and remodels the vascular microenvironment.

Dipeptidyl Peptidase‐4 Inhibitor Use and Risk of Pemphigus Vulgaris and Foliaceus: A Retrospective Cohort Study Using Databases of the Korea National Health Insurance Claims and the National Health Screening Examination

The Journal of Dermatology, EarlyView.
ABSTRACT Although population‐based studies have reported an increased risk of bullous pemphigoid and pemphigus associated with dipeptidyl peptidase‐4 (DPP‐4) inhibitors, there is limited, well‐designed epidemiological evidence for pemphigus vulgaris (PV), which has only been supported by case reports thus far.

Keratin Retraction and Desmoglein3 Internalization Independently Contribute to Autoantibody-Induced Cell Dissociation in Pemphigus Vulgaris

Frontiers in Immunology, 2018
Pemphigus vulgaris (PV) is a potentially lethal autoimmune disease characterized by blister formation of the skin and mucous membranes and is caused by autoantibodies against desmoglein (Dsg) 1 and Dsg3.

Elevated CO2 and Temperature Alter Grass Pollen's Ability to Modify Transcriptome and Function of the Nasal Epithelium

Allergy, EarlyView.
We exposed human nasal epithelial tissues to pollen from grasses grown under different climate treatments (temperature and CO2). Pollen weakened epithelial tight junctions and altered cytokine‐related gene expression, with similar protein‐level effects.

The Functional Role and Molecular Characterization of the Therapeutic Target CLDN6 in Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Background The tight junction protein CLDN6 has been identified as a cancer‐associated cell surface marker that is rarely expressed in healthy tissues. In testicular germ cell tumors (GCT), CLDN6 is particularly detectable in seminomas, embryonal carcinomas, and choriocarcinomas.

Diacerein Disrupts Testicular Homeostasis: The Essential Role of Basal Cytokines in Maintaining Sertoli Cell Integrity and the Immune Microenvironment

Andrology, EarlyView.
ABSTRACT Background Pro‐inflammatory cytokines, TNF and IL‐1B, are essential for testicular homeostasis. Diacerein, an anti‐inflammatory drug, inhibits these cytokines, impairing M2 macrophages and Leydig cells (LCs). However, its impact on Sertoli cells (SCs) and M1 (CD68) macrophages remains unknown.
