Complement activation by bisretinoid constituents of RPE lipofuscin.
PURPOSE Studies implicate activation of complement among the processes involved in the pathogenesis of age-related macular degeneration (AMD). Questions pertain to the trigger(s) responsible for the complement-associated events. The authors previously reported that photooxidation products of A2E can activate complement. Here they have further explored these events. METHODS In vitro assays usi...

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...

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 کاملComplement activation by photooxidation products of A2E, a lipofuscin constituent of the retinal pigment epithelium.
Recent studies have implicated local inflammation and activation of complement amongst the processes involved in the pathogenesis of age-related macular degeneration (AMD). Several lines of investigation also indicate that bis-retinoid pigments, such as A2E, that accumulate as lipofuscin in retinal pigment epithelial (RPE) cells, contribute to the disease process. In an investigation of a poten...
