Inflammatory Response in the Hippocampus of PS1M146L/APP751SLMouse Model of Alzheimer's Disease: Age-Dependent Switch in the Microglial Phenotype from Alternative to Classic
Open accessAbstract
Although the microglial activation is concomitant to the Alzheimer's disease, its precise role (neuroprotection vs neurodegeneration) has not yet been resolved. Here, we show the existence of an age-dependent phenotypic change of microglial activation in the hippocampus of PS1xAPP model, from an alternative activation state with Aβ phagocytic capabilities (at 6 months) to a classic cytotoxic phenotype (expressing TNF-α and related factors) at 18 months of age. This switch was coincident with high levels of soluble Aβ oligomers and a significant pyramidal neurodegeneration.In vitro assays, using astromicroglial cultures, demonstrated that oligomeric Aβ42 and soluble extracts from 18-month-old PS1xAPP hippocampus produced a potent TNF-α induction whereas monomeric Aβ42 and soluble extract from 6- or 18-month-old control and 6-month-old PS1xAPP hippocampi produced no stimulation. This stimulatory effect was avoided by immunodepletion using 6E10 or A11. In conclusion, our results show evidence of a switch in the activated microglia phenotype from alternative, at the beginning of Aβ pathology, to a classical at advanced stage of the disease in this model. This change was induced, at least in part, by the age-dependent accumulation of extracellular soluble Aβ oligomers. Finally, these cytotoxic activated microglial cells could participate in the neuronal lost observed in AD.

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.
