Understanding RPE lipofuscin.
In the Research Highlight article titled ‘‘Rethinking A2E,’’ Smith et al. offer interpretations of the recent paper by Ablonczy et al., titled ‘‘Lack of Correlation Between the Spatial Distribution of A2E and Lipofuscin Fluorescence in the Human Retinal Pigment Epithelium.’’ Readers will benefit from further discussion. Although not acknowledged by Smith et al., RPE lipofuscin consists of multi...
متن کاملUnderstanding RPE Lipofuscin.
In the recent paper by Allingham et al., fundus autofluorescence (AF) was studied in relation to progression of geographic atrophy (GA) in age-related macular degeneration (AMD), a subject of intense ongoing interest. The primary conclusion was that rim area focal hyperautofluorescence (RAFH) was positively correlated with GA progression rate (r 1⁄4 0.49, P < 0.001), consistent with Bearelly et...
متن کاملPhotoreactivity of aged human RPE melanosomes: a comparison with lipofuscin.
PURPOSE To determine whether aging is accompanied by changes in aerobic photoreactivity of retinal pigment epithelial (RPE) melanosomes isolated from human donors of different ages, and to compare the photoreactivity of aged melanosomes with that of RPE lipofuscin. METHODS Human RPE pigment granules were isolated from RPE cells pooled into groups according to the age of the donors. Photoreact...
متن کاملPhotooxidation of RPE lipofuscin bisretinoids enhances fluorescence intensity
Light-related cycling of chemically reactive vitamin A aldehyde leads to the formation autofluorescent bis-retinoid pigments that accumulate as lipofuscin in retinal pigment epithelial cells. The amassing of these diretinoid compounds is implicated in the pathogenesis of age-related macular degeneration and in some inherited forms of retinal degeneration. For all of these fluorophores, extended...
