Single‐cell RNA sequencing revealed the T‐cell heterogeneity and exhaustion subsets of Helicobacter pylori‐induced gastritis‐to‐cancer transformation

VIEW, EarlyView.
H. pylori infection is a major cause of stomach cancer, but its effect on immune cells in tumors is unclear. Using single‐cell sequencing, we mapped the stomach tumor environment and discovered a specific exhausted T‐cell subtype, marked by the FYB1 gene, that is abundant in H. pylori‐positive tumors and linked to patient prognosis. Our findings reveal

Clinical outcomes of the PAUL glaucoma implant in primary open‐angle and pseudoexfoliative glaucoma eyes after failed glaucoma surgeries

Acta Ophthalmologica, EarlyView.
Abstract Purpose This study assesses the PAUL® glaucoma implant (PGI) in primary open angle glaucoma (POAG) and pseudoexfoliative glaucoma (PEXG) after failed glaucoma surgery. Given PEXG's more aggressive nature, limited research exists on PGI outcomes in this subgroup. This study aims to compare PGI's efficacy and safety in both conditions. Methods A

Congenital aniridia: European COST action ANIRIDIA‐NET guidelines for diagnosis, management and care

Acta Ophthalmologica, EarlyView.
Abstract Congenital aniridia is a rare ocular disorder affecting the majority of eye structures and can be associated with systemic manifestations. The main visible phenotypic characteristic is the partial or complete absence of the iris; however, foveal hypoplasia is a more frequent and reliable clinical sign. Other ocular comorbidities are associated

Graded potential of neural crest to form cornea, sensory neurons and cartilage along the rostrocaudal axis [PDF]

, 2004
Neural crest cells arising from different rostrocaudal axial levels form different sets of derivatives as diverse as ganglia, cartilage and cornea. These variations may be due to intrinsic properties of the cell populations, different environmental ...

Exploring the histopathological signature of repeat‐mediated Fuchs endothelial corneal dystrophy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the histological differences between Fuchs endothelial corneal dystrophy (FECD) cases with and without the most common genetic risk factor, expansion of a CTG repeat (CTG18.1) within the TCF4 gene. Methods Formalin‐fixed paraffin‐embedded corneal tissues were compared retrospectively, and CTG18.1 status was determined from

Blockade of mitochondrial components release by exosome pathway promotes the pathogenesis of Fuchs endothelial corneal dystrophy

Cell Death Discovery
Fuchs endothelial corneal dystrophy (FECD) is the leading indication of corneal transplantation worldwide and the focus of pathogenesis has been on the corneal endothelium. Instead of cellular analysis, we aimed to identify the protein changes of aqueous

Towards Clinical Application: Calcium Waves for In Vitro Qualitative Assessment of Propagated Primary Human Corneal Endothelial Cells

Cells
Corneal endothelium cells (CECs) regulate corneal hydration between the leaky barrier of the corneal endothelium and the ionic pumps on the surface of CECs. As CECs do not regenerate, loss of CECs leads to poor vision and corneal blindness.

Aniridia‐associated keratopathy: Clinical and molecular mechanisms of disease progression and emerging therapeutic targets

Acta Ophthalmologica, EarlyView.
Abstract Congenital aniridia is a rare genetic disorder primarily caused by pathogenic variants of the PAX6 gene. It leads to various panocular anomalies, including aniridia‐associated keratopathy (AAK). This review highlights recent insights into its pathogenesis, focusing on clinical staging, microstructural changes in the cornea and molecular ...
