Summary
This review examines how exosome-based crosstalk between microglia, retinal neurons, and other ocular cells contributes to neuroinflammation and neurodegeneration in glaucoma. While not directly addressing lighting interventions, the findings provide mechanistic insights into retinal pathology that may inform understanding of light-induced retinal stress and disease progression.
Key Findings
- Exosomes derived from non-pigment ciliary epithelium regulate trabecular meshwork function in response to oxidative stress, contributing to aqueous drainage dysregulation in glaucoma.
- A complex regulatory network involving microglia, retinal ganglion cells, retinal pigment epithelium, and immune effector cells uses exosome-based signaling to maintain tissue homeostasis and propagate neuroinflammation in glaucoma pathogenesis.
- Exosome cargo composition, particularly microRNA content, concentration, size, and ionization potential, are key determinants of their pathological effects, though many mechanisms remain poorly understood.
