What is lipofuscin? Defining characteristics and differentiation from other autofluorescent lysosomal storage bodies
Abstract
Lipofuscins, also known as age-pigments, have three defining characteristics: (1) they consist of intracellular secondary lysosomes; (2) they have a yellow autofluorescent emission when excited by near ultraviolet or blue light; and (3) they accumulate during normal senescence. Lysosomal storage bodies with similar fluorescence properties accumulate in various cell types as a result of specific pathological conditions or experimental manipulations. As a class, the latter are often referred to as ceroid pigments. In general, the mechanisms involved in the formation of ceroid pigments cannot be assumed to be closely similar to those involved in lipofuscin formation. In fact, the mechanisms of formation almost certainly differ, not only between lipofuscins and ceroids, but also among different lipofuscins and different ceroids. Presently, the most detailed knowledge about the mechanisms involved in lipofuscin formation come from studies on the retinal pigment epithelium (RPE) of the eye. These studies indicate that at least the autofluorescent constituents of RPE lipofuscin are generated from derivatives of vitamin A that occur in the retina. Oxidative stress to the retina appears to promote the formation of these RPE fluorophores. Whether similar mechanisms are involved in the formation of the lipofuscins that occur in other tissues remains to be determined. The mechanisms involved in RPE lipofuscin fluorophore formation are closely related to metabolic pathways that are specif…

“Taken together, these pieces of evidence have led to the proposal that bis-retinoid precursors of lipofuscin, such as A2PE, form in the photoreceptor OS from all-trans retinal that is escaping reduction to retinol (Katz and Redmond, 2001; Katz and Robinson-Jr, 2002; Sparrow et al., 2010).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
