Oligodendrocytes produce amyloid-β and contribute to plaque formation alongside neurons in Alzheimer’s disease model mice
Open accessPublished version of a preprint
Abstract
Amyloid-β (Aβ) is thought to be neuronally derived in Alzheimer’s disease (AD). However, transcripts of amyloid precursor protein ( APP ) and amyloidogenic enzymes are equally abundant in oligodendrocytes (OLs). By cell-type-specific deletion of Bace1 in a humanized knock-in AD model, APP NLGF , we demonstrate that OLs and neurons contribute to Aβ plaque burden. For rapid plaque seeding, excitatory projection neurons must provide a threshold level of Aβ. Ultimately, our findings are relevant for AD prevention and therapeutic strategies.

Written from the paper’s full text.
TL;DR
Oligodendrocytes express amyloidogenic machinery and contribute to Aβ plaque burden in a humanized APP knock-in AD mouse model, but excitatory neurons must supply a threshold level of Aβ for rapid plaque seeding. Cell-type-specific Bace1 deletion shows oligodendroglial Aβ accounts for roughly 30% of plaque burden, while neuronal Aβ drives most plaque formation.
Key findings
- Mouse and human oligodendrocytes express APP, BACE1, PSEN1 and PSEN2 at levels similar to neurons; in human cortical tissue, approximately 50% of gray matter oligodendrocytes expressed considerable APP and BACE1 mRNA in both AD cases and controls.
- Oligodendrocyte-specific Bace1 knockout in APPNLGF mice (OL-Bace1cKO;AD) reduced plaque burden by approximately 30% versus controls in both sexes, with the greatest decrease in plaque amount and size in the alveus.
- Excitatory neuron-specific Bace1 knockout (ExN-Bace1cKO;AD) reduced plaque burden by 95–98% versus controls, but soluble Aβ42 remained at 14.925% ± 0.066% in cortex and 27.604% ± 0.072% in white matter, indicating residual non-excitatory-neuron Aβ production.
- OL-ExN-Bace1cKO;AD mice developed almost no cerebral plaques and showed almost complete loss of Aβ42 compared with ExN-Bace1cKO;AD samples; heterozygous APPNLGF mice developed less than 10% plaque burden rather than 50%, and 12-month-old ExN-Bace1cKO;AD mice showed considerable plaque deposition.
Methods
- Reanalyzed four mouse and three human single-cell/single-nucleus RNA sequencing datasets for APP, BACE1, PSEN1 and PSEN2 expression using Seurat and SCTransform; validated expression with in situ hybridization in mouse and human tissue.
- Generated conditional Bace1 knockout APPNLGF knock-in mice using Cnp-Cre for oligodendrocytes and Nex-Cre for dorsal telencephalic excitatory neurons, with littermate controls; analyzed both sexes.
- Used light sheet microscopy of Congo red-stained hemibrains at 6 months for plaque burden, electrochemiluminescence immunoassay for Aβ38/Aβ40/Aβ42, western blotting, electron microscopy, and in vitro oligodendrocyte cultures; statistics included unpaired two-tailed Student’s t-tests and one-way ANOVA with Tukey multiple comparison tests, with n = 5 per sex for LSM and n = 7 per group for immunoassay.
Limitations
- The paper states that Bace1 conditional knockout could not be validated by immunocytochemistry using the 3D5 antibody; validation was instead performed by immunoblotting sorted oligodendrocytes.
- The paper states that blinding was not possible for various imaging analyses because Bace1 conditional knockout visibly affected plaque load, and that no statistical methods were used to pre-determine sample sizes.
- Evident from the text: Cnp-Cre showed low but nonzero neuronal recombination (cortical 0.756% ± 0.057%; hippocampal 0.468% ± 0.111% tdTomato+ neurons), and human tissue analysis used a small sample (control: one female, two male; AD: two female, two male).

The In vitro fibrillation kinetics section describes sigmoidal behavior in amyloid fibrillation and reports that the model fits Aβ-40 fibrillation data. It identifies Aβ-40 as a protein fragment that aggregates into plaques, but does not show that plaque formation itself follows sigmoidal kinetics; the Conclusions likewise concern fibril formation, not plaque growth.

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.
A language model drew the claims from the paper on 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
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.
