Short‐Chain Fatty Acids: Microbial Metabolites Driving Gut‐Eye Axis Signaling

Comprehensive Physiology, Volume 16, Issue 5, October 2026.
Short‐chain fatty acids generated by gut microbial fermentation link diet to ocular physiology via the gut–eye axis. Through systemic distribution, these metabolites regulate GPCR signaling, epigenetic pathways, inflammation, and angiogenesis, shaping retinal homeostasis and highlighting therapeutic potential in ocular vascular and inflammatory ...

Age related grid-wise spatial analysis of choroidal parameters in well characterised healthy population

Scientific Reports
Choroidal vascularity index (CVI) is an image-based metric applied to assess the choroid in disease but poorly explored in natural aging. In this retrospective cohort study, we assessed a single eye of 309 healthy individuals from 20 to 70 + years, and ...

Müller Glia–Vasculature Interactions in the Developing Retina

Glia, Volume 74, Issue 10, October 2026.
Retinal vascular layers form normally despite loss of cholinergic retinal waves. Müller glial processes contact endothelial tip cells early and form Aquaporin‐4‐enriched endfeet. Glial endfoot calcium signals are compartmentalized and occur largely independently of neural activity. ABSTRACT Coordinated signaling among neurons, glia, and the vasculature

DNA Origami Uptake in Y‐79 Retinoblastoma Cells Driven by Oligolysine Coating

Small Structures, Volume 7, Issue 10, October 2026.
We show that polymeric coating can enable DNA origami nanoparticle internalization into ocular retinoblastoma cells. Not only are the coated nanoparticles well‐tolerable to the cells, but they also remain mobile in the vitreous of a porcine ex vivo model.

Insights into the modulation of age‐related macular degeneration: Molecular and systems‐level perspectives

Acta Ophthalmologica, Volume 104, Issue S293, Page S4-S35, October 2026.
ENGLISH SUMMARY In developed countries, age‐related macular degeneration (AMD) is the leading cause of visual impairment in the aging population. Understanding of its pathogenesis is limited and the number of patients is predicted to continue rising. AMD is classified into two main forms: dry and neovascular AMD (dAMD and nAMD, respectively).
