文摘

The retinal pigment epithelium (RPE) is a monolayer to function as a compact barrier between photoreceptor and choroid and also a regulator of the overlying photoreceptor layer by providing nutrients. If RPE is damaged, choroidal neovascularization is occurred, accompanied by inflammation, which leads to degeneration of whole retina layer and furthermore, loss of vision. Thus, the preservation of RPE layer is very critical treatment to block the progression and occurrence of diverse ocular disease, inducing age-related macular degeneration (AMD). In this study, we explored the new role of SP in RPE regeneration. After confirming the expression of NK-1R on ARPE-19 cells, we treated SP to ARPE-19 cells in vitro to evaluate the effect of SP on proliferation rate and migratory capacity. SP could promote proliferation and migration of ARPE-19 in dose-dependent manner in vitro. Based on the in vitro data, 5nmole/kg of SP was intravitreally treated to laser-induced RPE damaged mice in vivo, showing that PBS-injected mice had severed disturbed retina layer, whereas SP-injected mice maintained retina layer more intact without detachment of RPE. In addition to histological comparison, the efficacy of SP was assessed according to the score that indicate the severity of retina degeneration. This confirmed that SP can exert the beneficial effect on laser-induced RPE damage. Collectively, our findings suggest that SP can stimulate the regeneration of RPE layer and thus, it may be possible that SP is used as the new therapeutics for RPE-damaged disease including AMD.
