Loss of SORLA causes endo-lysosomal defects in neurons, including in endosomal recycling, autophagy, and lysosome function, resulting in increased secretion of toxic Aβ species and impaired synaptic activity.
“Studies investigating the role of SORLA in ad pathogenesis have extensively focused on neurons and revealed that loss of SORLA causes endo‐lysosomal defects in neurons, specifically in endosomal recycling, autophagy, and lysosome function, ultimately resulting in increased secretion of toxic Aβ species and impaired synaptic activity in neurons (Andersen et al. 2022; Hung et al. 2021; Knupp et al.”

The Introduction and Discussion describe SORLA-dependent endosomal recycling and link reduced SORLA activity to increased Aβ production; the Results report enlarged neuronal endosomes in SORL1-deficient minipigs. Our copy does not establish defects in autophagy or lysosome function or characterize the increased Aβ as toxic. In the Results section on 21-month-old minipigs, the authors report no decrease in a PET measure of neuronal synaptic activity, while cautioning that few animals were studied. (LLM, conf=0.90)

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.
