Microglial TSPAN4‐Dependent Migrasomes Promote Pathological Retinal Neovascularization via Immune‐Vascular Crosstalk

Advanced Science, EarlyView.
Combined high‐glucose and hypoxic stress switches microglia into a TSPAN4‐dependent migrasome‐producing state. These migrasomes deliver pro‐angiogenic signals to endothelial cells, activating HIF‐1α/VEGF signaling, disrupting vascular junctions, and fueling pathological neovascularization. This work uncovers migrasome‐mediated immune‐vascular crosstalk

Ocular and Systemic Findings in COL2A1 and COL11A1 Stickler Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Stickler syndrome is most commonly caused by variants in COL2A1 and COL11A1 genes. The purpose of this study was to describe genetic variants and phenotypes in COL2A1 and COL11A1 Stickler syndrome. We performed a retrospective genotype–phenotype evaluation of COL2A1 and COL11A1 Stickler syndrome subjects. Thirty‐two subjects with COL2A1 and 13

Mechanistic Diversity in Photoexcited Radical Redox Chemistry: A Critical Evaluation

Angewandte Chemie International Edition, EarlyView.
Many high‐profile examples of photoredox catalysis are proposed to proceed via excitation of an open‐shell intermediate form of the catalyst. However, there is much debate over whether such mechanisms are realistic and, if so, exactly how they can occur.
