Nanobiotechnology‐Based Approaches for Uveal Melanoma Treatment

SmartMat, Volume 7, Issue 1, February 2026.
Emerging platforms for uveal melanoma combine precision drug delivery, ROS‐amplifying modalities, and nucleic acid transport to overcome ocular barriers and immunosuppressive niches. Targeted nanoparticles, virus‐like constructs, and injectable depots enable localized activation, controlled release, and gene‐level reprogramming.

MSC‐Derived Exosomal lnc‐AGT‐3: A Novel Anti‐Angiogenic Target in Age‐Related Macular Degeneration Through p53 Signaling Pathway

Aging Cell, Volume 25, Issue 2, February 2026.
MSC‐derived exosomes deliver lnc‐AGT‐3 to vascular endothelial cells, where it binds hnRNP K in the nucleus. This interaction inhibits p53 ubiquitination, enhancing p53 stabilization and transcriptional activation of anti‐angiogenic targets TSP1. Consequently, p53‐mediated signaling is potentiated, effectively suppressing choroidal neovascularization ...

Intravitreal anti‐vascular endothelial growth factor injections and risks of stroke in patients with neovascular age‐related macular degeneration—A registry‐based cohort study

Acta Ophthalmologica, Volume 104, Issue 1, Page 98-105, February 2026.
Abstract Background Intravitreal Anti‐Vascular Endothelial Growth Factor (VEGF) rescues retinal vasculatures and prevents disease progression in patients with neovascular Age‐Related Macular Degeneration (nAMD). However, systemic anti‐VEGF may increase the risk of thromboembolic related complications including stroke and TIA. This study aims to explore
