Phenotypes Examined

  • Plaques
  • Tangles
  • Neuronal Loss
  • Gliosis
  • Synaptic Loss
  • Changes in LTP/LTD
  • Cognitive Impairment

When visualized, these phenotypes will distributed over a 18 month timeline demarcated at the following intervals: 3mo, 6mo, 9mo, 1yr, 15mo, 18mo+.

APPSwe/PSEN1(A246E)

Observed
  1. X
    Plaques at 39

    By 9 months of age, amyloid plaques develop in the hippocampus and subiculum, later extending to the cortex (Borchelt et al., 1997). The striatum and thalamus are relatively spared out to 18 months of age. Amyloid pathology is more severe in female mice, with a greater amyloid burden measured at 12 and 17 months of age (Wang et al., 2003).

  2. X
    Gliosis at 52

    By one year of age, reactive gliosis is observed in the cortex and hippocampus and is associated with dystrophic neurites (Borchelt et al., 1997).

  3. X
    Cognitive Impairment at 48

    Age-associated cognitive impairment, as measured by the Morris water maze, was observed in 11 to 12-month-old males. Both acquisition and retention were impaired. No impairment at 3-4 months of age. At both time points mice performed normally on a position discrimination task in the T-maze (Puoliväli et al., 2002).

Absent
  • Tangles at

    Not observed.

  • Neuronal Loss at

    There was no difference in neuronal numbers in the cingulate cortex compared with wild-type mice (Xiang et al., 2002).

No Data
  • Synaptic Loss at

    No data.

  • Changes in LTP/LTD at

    No data.
