Cultured RPE phosphpproteome - Quantitative phosphoproteomics reveals involvement of multiple signaling pathways in early phagocytosis by the retinal pigmented epithelium

ABSTRACT: One of the major biological functions accomplished by the retinal pigmented epithelium (RPE) is the clearance of shed photoreceptor outer segments (POS) through a multistep process referred to as phagocytosis. Phagocytosis helps maintain the viability of photoreceptors which otherwise could succumb to the high metabolic flux and photo-oxidative stress associated with visual processing. Regulatory mechanisms underlying phagocytosis in the RPE are not fully understood, although dysfunction of this process contributes to the pathogenesis of multiple human retinal degenerative disorders, including age-related macular degeneration (AMD). Here we present an integrated analysis of phagocytosing cultured-RPE cells.
