Parallel findings in age-related macular degeneration and Alzheimer’s disease

Abstract

Age is a common risk factor for Alzheimer's disease (AD) and age-related macular degeneration (AMD). Because of the increasing age of the population, these two age-related diseases have recently received a great deal of attention. In addition to age as a risk factor, AD and AMD have many characteristics in common. An important characteristic common to both diseases is the presence of amyloid β (Aβ) in the senile plaques of the AD brain and in the drusen of AMD patients. We have focused on the role of Aβ as a key regulator of the progression from drusen to AMD, and our results have shown that Aβ causes an imbalance of angiogenesis-related factors in the retinal pigment epithelial (RPE) cells. Mice that lack the Aβ-degrading enzyme neprilysin develop RPE degeneration, and the sub-RPE deposits that are formed have features similar to those of AMD in humans. These data suggest that a common pathogenic mechanism might exist between AMD and AD. Thus, therapeutic approaches that have targeted Aβ in patients with AD can also be applied to AMD. In this review, we summarise recent findings on the shared characteristics and perspectives between AMD and AD, beginning with the mechanism of Aβ deposition and including a discussion of Aβ-targeted therapeutic approaches for both AD and AMD.

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.
