Abstract

Macroautophagy is a lysosomal degradative pathway essential for neuron survival. Here, we show that macroautophagy requires the Alzheimer's disease (AD)-related protein presenilin-1 (PS1). In PS1 null blastocysts, neurons from mice hypomorphic for PS1 or conditionally depleted of PS1, substrate proteolysis and autophagosome clearance during macroautophagy are prevented as a result of a selective impairment of autolysosome acidification and cathepsin activation. These deficits are caused by failed PS1-dependent targeting of the v-ATPase V0a1 subunit to lysosomes. N-glycosylation of the V0a1 subunit, essential for its efficient ER-to-lysosome delivery, requires the selective binding of PS1 holoprotein to the unglycosylated subunit and the Sec61alpha/oligosaccharyltransferase complex. PS1 mutations causing early-onset AD produce a similar lysosomal/autophagy phenotype in fibroblasts from AD patients. PS1 is therefore essential for v-ATPase targeting to lysosomes, lysosome acidification, and proteolysis during autophagy. Defective lysosomal proteolysis represents a basis for pathogenic protein accumulations and neuronal cell death in AD and suggests previously unidentified therapeutic targets.

  • The findings support an emerging concept that acidification impairment may be a proximal biochemical event in AD, common to multiple genetic risk factors that cause or promote AD.

    “The findings support an emerging concept that acidification impairment may be a proximal biochemical event in AD, common to multiple genetic risk factors that cause or promote AD (Lee et al., 2010;Xue et al., 2014;Vidoni et al., 2016).”

    The Discussion (page not available in our copy) links impaired lysosomal acidification to PS1 mutations that cause familial AD and suggests lysosomal dysfunction may also contribute to sporadic AD. It does not establish that acidification impairment is common to multiple distinct genetic risk factors for AD; its genetic findings concern PS1. (LLM, conf=0.87)

  • In familial AD caused by presenilin 1 (PSEN1) mutations, failed lysosomal delivery of the V0a1 subunit markedly impairs lysosomal acidification, inducing acid hydrolase inhibition and lysosomal substrate buildup in patient primary fibroblasts.

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.
