Orchestrated experience-driven Arc responses are disrupted in a mouse model of Alzheimer's disease
Open accessAbstract
Experience-induced expression of immediate-early gene Arc (also known as Arg3.1) is known to be important for consolidation of memory. Using in vivo longitudinal multiphoton imaging, we found orchestrated activity-dependent expression of Arc in the mouse extrastriate visual cortex in response to a structured visual stimulation. In wild-type mice, the amplitude of the Arc response in individual neurons strongly predicted the probability of reactivation by a subsequent presentation of the same stimulus. In a mouse model of Alzheimer's disease, this association was markedly disrupted in the cortex, specifically near senile plaques. Neurons in the vicinity of plaques were less likely to respond, but, paradoxically, there were stronger responses in those few neurons around plaques that did respond. To the extent that the orchestrated pattern of Arc expression reflects nervous system responses to and physiological consolidation of behavioral experience, the disruption in Arc patterns reveals plaque-associated interference with neural network integration.

Soluble oligomeric tau may play a more essential role in neurodegeneration than insoluble fibrillar tau, including NFTs.
“These findings indicate that soluble oligomeric tau may play a more essential role in neurodegeneration than insoluble fibrillar tau (including NFT), the “tau we can see”.”

Soluble tau, rather than fibrillar tau, impacts responsiveness of neurons to environmental stimuli in hippocampus after memory formation.
“From assessments of immediate early gene expression in the hippocampus after memory formation, it again appears that soluble tau, rather than fibrillar tau, seems to impact the responsiveness of neurons to environmental stimuli.”

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.
