Abstract

Hippocampal atrophy and neuron loss are commonly found in Alzheimer's disease (AD). However, the underlying molecular mechanisms and the fate in the AD hippocampus of subpopulations of interneurons that express the calcium-binding proteins parvalbumin (PV) and calretinin (CR) has not yet been properly assessed. Using quantitative stereologic methods, we analyzed the regional pattern of age-related loss of PV- and CR-immunoreactive (ir) neurons in the hippocampus of mice that carry M233T/L235P knocked-in mutations in presenilin-1 (PS1) and overexpress a mutated human beta-amyloid precursor protein (APP), namely, the APP(SL)/PS1 KI mice, as well as in APP(SL) mice and PS1 KI mice. We found a loss of PV-ir neurons (40-50%) in the CA1-2, and a loss of CR-ir neurons (37-52%) in the dentate gyrus and hilus of APP(SL)/PS1 KI mice. Interestingly, comparable PV- and CR-ir neuron losses were observed in the dentate gyrus of postmortem brain specimens obtained from patients with AD. The loss of these interneurons in AD may have substantial functional repercussions on local inhibitory processes in the hippocampus.

  • In APP/PS1KI mice, significantly reduced CR- and PV-positive neuron numbers were found in the hippocampus, while no changes were detected in layers V and VI of the frontal cortex despite significantly reduced pyramidal neurons and massive thioflavin S-positive extracellular amyloid deposits.

    “A related finding was reported in APP/PS1KI mice, which presented with significantly reduced CR- and PV-positive neuron numbers in the hippocampus [125]. Interestingly, no changes were detected in layers V and VI of the frontal cortex in this model, although pyramidal neurons were significantly reduced and massive thioflavin S-positive extracellular amyloid deposits were present [129].”

    Experimental — accuracy not yet measured
  • Most available studies report a loss of CR- and PV-positive interneurons in the hippocampal formation in AD transgenic mice.

    “Quantitative studies investigating interneuron populations in transgenic AD mouse models yielded more conclusive results, with most of the available studies reporting a loss of CR- and PV-positive interneurons in the hippocampal formation in AD transgenic mice [59,122,123,124,125,126].”
  • In Alzheimer's disease patients, PV-INs are decreased in the dentate gyrus.

    “In AD patients, however, a decrease in PV-INs was reported in the dentate gyrus, and an increase in PV-INs was reported in the piriform cortex [34,37,38].”

  • In Alzheimer's disease patients, PV-INs are increased in the piriform cortex.

    “In AD patients, however, a decrease in PV-INs was reported in the dentate gyrus, and an increase in PV-INs was reported in the piriform cortex [34,37,38].”

  • Hippocampal PV-IN numbers are decreased in two mouse models of Alzheimer's disease.

    “For example, decreases in the number of PV-INs in the hippocampus were observed in two mouse models of AD [33,34], while an increase in hippocampal PV immunoreactivity was observed in another [35], and no change in the number of hippocampal PV-positive interneurons was observed in yet another model [36].”

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.
