WebThe retinal pigment epithelium (RPE) is located between the choroid and the outer segment of the photoreceptor cells, and is a transport channel for ions, water, nutrients and metabolic end products between the subretinal space and the choroidal blood vessels; it is mainly composed of a single layer of pigment epithelial cells. WebApr 12, 2024 · Introduction. Retinal pigment epithelium (RPE) is a monolayer of pigment cells that maintains photoreceptor integrity, primarily by phagocytosing and recycling retinal photoreceptor outer segments ().In addition, RPE cells are involved in immune responses by maintaining immune homeostasis within the eye ().Thus, inflammatory dysfunction of …
