APOE genotype determines cell-type-specific pathological landscape of Alzheimer’s disease
Open accessAbstract
The apolipoprotein E (APOE) gene is the strongest genetic risk modifier for Alzheimer's disease (AD), with the APOE4 allele increasing risk and APOE2 decreasing it compared with the common APOE3 allele. Using single-nucleus RNA sequencing of the temporal cortex from APOE2 carriers, APOE3 homozygotes, and APOE4 carriers, we found that AD-associated transcriptomic changes were highly APOE genotype dependent. Comparing AD with controls, APOE2 carriers showed upregulated synaptic and myelination-related pathways, preserving synapses and myelination at the protein level. Conversely, these pathways were downregulated in APOE3 homozygotes, resulting in reduced synaptic and myelination proteins. In APOE4 carriers, excitatory neurons displayed reduced synaptic pathways similar to APOE3, but oligodendrocytes showed upregulated myelination pathways like APOE2. However, their synaptic and myelination protein levels remained unchanged or increased. APOE4 carriers also showed increased pro-inflammatory signatures in microglia but reduced responses to amyloid-β pathology. These findings reveal APOE genotype-specific molecular alterations in AD across cell types.

The first snRNA-seq dataset was performed on temporal cortex tissue, and the second was performed on entorhinal cortex and superior frontal gyrus.

The STAR Methods (page unavailable) describe isolating nuclei from frozen temporal cortex for this paper’s snRNA-seq work, supporting the former dataset’s tissue location. The passages in our copy do not establish that a second dataset was performed on entorhinal cortex and superior frontal gyrus; a search for those regions found no supporting passage. (LLM, conf=0.84)
Experimental — accuracy not yet measuredPLCG2 is also expressed in neurons, as evidenced in publicly available single-nucleus RNA-seq datasets from human brain.

From PLCG2 downregulation impairs synaptic function and increases Alzheimer’s disease hallmarks in neuronal cultures (2026) · cites this paper as [22]
The Results describe human-brain snRNA-seq data and identify neuronal populations, while the STAR Methods describe integration of publicly available datasets. Neither those passages nor searches for “PLCG2” and “PLCG2 expressed in neurons” found a passage reporting PLCG2 expression in neurons. Our copy therefore does not verify the specific expression claim. (LLM, conf=0.72)
Experimental — accuracy not yet measuredPLCG2 is also expressed in neurons.
“we and others found that PLCG2 is also expressed in neurons22–24”
From PLCG2 downregulation impairs synaptic function and increases Alzheimer’s disease hallmarks in neuronal cultures (2026) · cites this paper as [22]
The Results passages describe gene-expression changes in excitatory and inhibitory neurons, but do not identify PLCG2 as a neuron-expressed gene. Searches of our copy for “PLCG2” and “phospholipase C gamma 2 expression in neurons” found no passage addressing that claim. (LLM, conf=0.72)

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.
