Line PS19, PS19Tg B6;C3-Tg(Prnp-MAPT*P301S)PS19Vle/J (C57BL/6 x C3H)F1 MAPT MAPT P301S Transgenic line expressing mutant human tau under the direction of the mouse prion protein (Prnp) promoter. The transgene codes for tau with four microtubule-binding domains and one N-terminal insert (4R/1N). MAPT: Transgenic Alzheimer's Disease, Frontotemporal Dementia Neuron loss and brain atrophy by eight to 12 months, especially in the hippocampus and spreading to the neocortex and entorhinal cortex. Neurofibrillary tangles in the neocortex, amygdala, hippocampus, brain stem, and spinal cord. Neuroinflammation with microgliosis and astrocytosis. Impairments in spatial memory and learning ability in Morris water maze. Paralysis at seven to 10 months associated with a hunched-back posture followed by feeding difficulties. About 80 percent mortality by 12 months with median survival of about nine months. Clasping and limb retraction when lifted by the tail at three months, followed by limb weakness and brain atrophy. Homozygous females do not mate. The Jackson Lab: Stock# 008169; Live Yoshiyama et al., 2007 Yes
Tau22 C57BL6/CBA; backcrossed to C57BL6 MAPT MAPT G272V, MAPT P301S Transgene containing the cDNA of the 412 amino acid isoform of human 4-repeat tau mutated at sites G272V and P301S under a Thy1.2 promotor. MAPT: Transgenic Frontotemporal Dementia, Alzheimer's Disease A variety of tau pathologies starting at 3 months, including neurofibrillary tangle-like inclusions, rare ghost tangles, and paired helical filament-like structures. Hyperphosphorylation of tau on many epitopes (e.g. AT8, AT100, AT180, AT270, 12E8, tau-pSer396, and AP422) and mild astrogliosis. Increased anxiety and delayed learning from 3 months, and reduced spatial memory at 10 months. No changes in overall motor activity and no gross motor deficits. Increased depression-like and aggressive behavior, co-occurring with disturbances in nocturnal activity. Fertile with normal frequency and size of litters. Stably transmits the transgene to offspring. Deficits in hippocampal synaptic transmission. Available through Luc Buée. Schindowski et al., 2006 Yes

  • 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: 1mo, 3mo, 6mo, 9mo, 1yr, 15mo, 18mo+.

Tau P301S (Line PS19)

Observed
  1. Tangles at 23

    Neurofibrillary tangles in the neocortex, amygdala, hippocampus, brain stem and spinal cord at 6 months with progressive accumulation (Yoshiyama et al., 2007).

  2. Neuronal Loss at 39

    Neuron loss in the hippocampus and entorhinal cortex by 9-12 months, as well as in the amygdala and neocortex becoming more severe by 12 months (Yoshiyama et al., 2007).

  3. Gliosis at 11

    Microgliosis at 3 months, especially in the white matter of the brain and spinal cord. Increased microgliosis by 6 months in white and gray matter of the hippocampus, amygdala, entorhinal cortex and spinal cord. Microglial activation precedes astrogliosis (Yoshiyama et al., 2007).

  4. Synaptic Loss at 13

    Synaptophysin immunoreactivity decreased progressively from 3-6 months in the CA3 region of the hippocamus. Impaired synaptic function (Yoshiyama et al., 2007).

  5. Changes in LTP/LTD at 26

    Reduced LTP in the CA1 region of the hippocampus at 6 months. Altered basal synaptic transmission (smaller fiber volley amplitude, fEPSP slopes, and amplitudes) (Yoshiyama et al., 2007).

  6. Cognitive Impairment at 27

    Impairments in spatial learning and memory ability in the Morris water maze in 6 month old animals (Takeuchi et al., 2011).

Phenotype
MAPT MAPT P301S MAPT: Transgenic Alzheimer's Disease, Frontotemporal Dementia

Neuron loss and brain atrophy by eight to 12 months, especially in the hippocampus and spreading to the neocortex and entorhinal cortex. Neurofibrillary tangles in the neocortex, amygdala, hippocampus, brain stem, and spinal cord. Neuroinflammation with microgliosis and astrocytosis.

Impairments in spatial memory and learning ability in Morris water maze. Paralysis at seven to 10 months associated with a hunched-back posture followed by feeding difficulties. About 80 percent mortality by 12 months with median survival of about nine months.

THY-Tau22

Observed
  1. Tangles at 13

    Heterozygous animals develop tau pathology starting at 3-6 months. Pathology becomes more severe and widespread with age. Neurofibrillary tangle-like inclusions occur (Gallyas and MC1+) along with rare ghost tangles and paired helical filament-like structures (Schindowski et al., 2006).

  2. Neuronal Loss at 52

    Loss of cells in the CA1 region of the hippocampus from 12 months as measured by DAPI staining and Nissl/cresyl-violet (Schindowski et al., 2006). Also, a significant reduction in the number of choline acetyltransferase (ChAT)-immunopositive cholinergic neurons in the medial septum has been reported (Belarbi et al., 2011).

  3. Gliosis at 13

    Age-dependent increase in the number of GFAP+ astrocytes in the hippocampus (hilus, CA1, CA3), cerebral cortex, corpus callosum (Schindowski et al., 2006).

  4. Changes in LTP/LTD at 39

    Altered paired pulse facilitation (PPF), a form of presynaptic short-term plasticity in 9-10 month old heterozygous animals: PPF increased at 10 ms. Also at this age, impaired maintenance of long term depression as compared with wild-type littermates (Van der Jeugd et al., 2011). Deficit in basal synaptic transmission in the hippocampus, but normal LTP (Schindowski et al., 2006).

  5. Cognitive Impairment at 26

    Non-spatial memory affected as early as 6 months; spatial memory impaired only after 9 months (Van der Jeugd et al., 2013). Impaired appetitive responding (Lo et al., 2013).
