VEGFA and wet macular degeneration: Here, we investigate the therapeutic efficacy of eVLPs for transient delivery of Vegfa-targeting Cas9 ribonucleoprotein in a laser-induced choroidal neovascularization mouse model of wet age-related macular degeneration.<h4>Results</h4>We find that Cas9-eVLPs enables efficient intracellular delivery in vitro, achieving up to 99% insertion and deletion frequency at Vegfa target locus and significant VEGFA protein downregulation in NIH/3T3 cells.
