Adherens junction distribution mechanisms during cell-cell contact elongation in Drosophila. [PDF]

PLoS ONE, 2013
During Drosophila gastrulation, amnioserosa (AS) cells flatten and spread as an epithelial sheet. We used AS morphogenesis as a model to investigate how adherens junctions (AJs) distribute along elongating cell-cell contacts in vivo.

The association between neural crest‐derived glia and melanocyte lineages throughout development and disease

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common

Loss of Twist1 leads to disruption of ciliary length, endocytic vesicle dynamics, and cell–cell junctions during neural tube formation

Developmental Dynamics, EarlyView.
Abstract Background Endocytosis constitutes a fundamental cellular process governing development through coordinated regulation of plasma membrane remodeling and ciliogenesis, processes essential for cell shape changes and tissue development. Although Twist1 null embryos display complete cranial neural tube (NT) closure defects and conditional knockout

Immune Checkpoint Inhibitors Induce Intestinal Epithelial Injury and a Senescence‐Like Phenotype

iNew Medicine, EarlyView.
ICI treatment promotes the infiltration of activated immune cells into the intestinal mucosa. This inflammatory microenvironment is associated with significant epithelial injury, characterized by the disruption of the epithelial barrier, the depletion of specialized secretory cell lineages, and the induction of a premature senescence phenotype ...

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 ...

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.

The Airway Epithelial Barrier in Childhood Asthma: A Central Player in Glucocorticoid Therapy, Resistance, and Severe Asthma

Pediatric Discovery, EarlyView.
ABSTRACT Childhood asthma remains a global public health challenge with suboptimal control, despite the availability of inhaled corticosteroids (ICS) as first‐line therapy. Glucocorticoids suppress inflammation and protect the airway epithelial barrier (AEB) via genomic and nongenomic pathways.

Human Colitis‐on‐Chip Model Reveals Dual Roles of Butyrate in Epithelial and Macrophage Defense Against Candida albicans Tissue Invasion

Small, EarlyView.
This study establishes a human immunocompetent colitis‐on‐chip model that mimics inflamed gut mucosa and enables quantitative analysis of Candida albicans tissue invasion under DSS‐induced injury. It reveals that microbiota‐derived butyrate simultaneously stabilizes epithelial junctions and reprograms macrophages via HDAC/NLRP3‐dependent mechanisms ...

Inflammatory Shift in Chronic Rhinosinusitis Amidst Guangzhou's Urbanization (2000–2018)

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) exhibits temporal and geographic diversity in pathological endotypes with progressive eosinophilic infiltration, while the underlying causes remain unclear. Current pathological endotypes determination relies on mean cell count per high‐power field, requiring accuracy optimization.

The epithelial integrity is preserved during particle exchange across the epithelium by macrophages and dendritic cells

European Respiratory Review, 2008
The epithelium of the human airway wall serves as structural and functional barrier against inhaled and deposited particulate antigen. Recently we have shown that human blood monocyte-derived dendritic cells (MDDC) and human blood monocytes derived ...
