Title
(EN) COMPOSITION FOR PREVENTION OR TREATMENT OF OCULAR DISEASES COMPRISING EXTRACELLULAR VESICLES DERIVED FROM MICROCOCCUS LUTEUS
Abstract
(EN)

Provided is a method for preventing, alleviating or treating an ocular disease including administering a composition containing vesicles derived from Micrococcus luteus as an active ingredient wherein the vesicles are delivered to the central nervous system including the retina through the blood-brain barrier (BBB); when epithelial cells and macrophages were treated with the vesicles, not only is the secretion of an inflammatory mediator by a biological causative factor considerably inhibited, but also NLRP3 protein expression by a biological causative factor is inhibited; and when the vesicles are administered to a rabbit model with an ocular disease caused by oxidative stress, retinal degeneration is significantly inhibited, thus the vesicles derived from Micrococcus luteus can be used for a composition for preventing, alleviating or treating an age-related ocular disease and an inflammatory ocular disease, including a pharmaceutical or health functional food composition.
