The responder transgene is the 1N4R isoform of human tau with the A152T mutation. Expression is constitutive unless suppressed by doxycycline. MAPT: Transgenic Alzheimer's Disease, Frontotemporal Dementia, Other Tauopathy Tangles or dense tau inclusions not observed. Abnormal accumulations of soluble tau. Age-dependent neuronal loss was observed in the hippocampus. Age-dependent learning and memory deficits in the Morris water maze. Nest building impaired. Social interaction, anxiety, exploratory behavior, and motor functions were normal. Increase in basal synaptic activity and epileptiform spikes. Life span normal.

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+.

hTau-A152T

Observed
  1. X
    Neuronal Loss at 87

    Neuron loss in the hippocampus was observed by 20 months.

  2. X
    Gliosis at 17

    Astrocytosis, but no differences in microglia.

  3. X
    Cognitive Impairment at 74

    In the Morris water maze, performance was impaired after 17 months of age. Nest building was impaired at 10-14 months. Social interaction, anxiety, exploratory behavior, and motor functions were unaltered.

Absent
  • Tangles at

    Abnormal accumulations of soluble tau were observed, but not tangles or tangle-like structures.

  • Changes in LTP/LTD at

    Unchanged at 20 months.

No Data
  • Plaques at

    No data.

  • Synaptic Loss at
