Abstract

A bigenic mouse is provided whose germ cells and somatic cells contain (i) inactive mouse TAU genes, and/or (ii) a transgene encoding the human TAU gene, with the transgene including all regulatory elements of the human TAU gene necessary for neuronal expression of the transgene in the bigenic mouse, and/or for human patterns of expression of the transgene in the bigenic mouse. The mice of the invention may contain one or two alleles for the human TAU gene (i.e., one or two TAU alleles). Mice of the invention are useful as a source of human Tau protein, and are useful as a model of Alzheimer's, Frontal Temporal Dementia and Parkinson's-like diseases.

Claims

A transgenic mouse having a genome comprising: (i) an inactive mouse TAU gene, and (ii) a transgene encoding either (a) the human TAU gene or (b) a mutated human TAU gene associated with FTDP-17, said transgene operatively linked to regulatory elements for neuronal expression of said transgene in said transgenic mouse, wherein said transgene expresses human Tau isoforms, and wherein said transgenic mouse develops Tau phosphorylation.
The mouse according to claim 1 , wherein said genome contains one allele encoding the human TAU gene.
The mouse according to claim 1 , wherein said genome contains two alleles encoding the human TAU gene.
A method of determining if a compound is capable of modulating an Alzheimer's like Tau pathology, comprising administering said compound to a mouse of claim 1 , and then examining said mouse for modulation of Alzheimer's like Tau pathology characteristics.
A method of determining if a compound is capable of inducing an Alzheimer's like Tau pathology, comprising administering said compound to a mouse of claim 1 , and then examining said mouse for development of Alzheimer's like Tau pathology characteristics.
A method of screening a compound for activity in treating an Alzheimer's like Tau pathology, comprising administering said compound to a mouse of claim 1 , and then examining said mouse for the treatment of said Alzheimer's like Tau pathology.
A method of determining if a compound is capable of modulating at least one frontotemporal dementia or Parkinson's-like disease, comprising administering said compound to a mouse of claim 1 , and then examining said mouse for modulation of characteristics of the disease.
A method of determining if a compound is capable of inducing at least one frontotemporal dementia or Parkinson's-like disease, comprising administering said compound to a mouse of claim 1 , and then examining said mouse for the inducement of the disease.
A method for screening a compound for activity in treatment of at least one frontotemporal dementia disease or Parkinson's-like disease, comprising administering said compound to a mouse of claim 1 , and then examining said mouse for the treatment of said disease.
A method of using the mouse of claim 1 to produce a human Tau protein, isoform of the protein, or mutated isoform of the protein, comprising the steps of:
allowing the mouse to produce the protein; and
removing the protein from the mouse.
A transgenic mouse whose germ cells and somatic cells contain an inactive mouse TAU gene, wherein Exon 1 of said inactive mouse TAU gene is deleted and replaced with an expression cassette having a heterologous gene operably linked with a promoter, being oriented in the opposite direction of transcription of said inactive mouse TAU gene, wherein said transgenic mouse is deficient in microtubule assembly and stabilization.
A transgenic mouse having a genome comprising a transgene encoding (a) the human TAU gene or (b) a mutated human TAU gene associated with FTDP-17, said transgene operatively linked to regulatory elements for neuronal expression of said transgene in said transgenic mouse, wherein said transgene expresses human Tau isoforms, and wherein said transgenic mouse develops Tau phosphorylation.
A method of determining if a compound is capable of modulating an Alzheimer's like Tau pathology, comprising administering said compound to a mouse of claim 12 , and then examining said mouse for modulation of Alzheimer's like Tau pathology characteristics.
A method of determining if a compound is capable of inducing an Alzheimer's like Tau pathology, comprising administering said compound to a mouse of claim 12 , and then examining said mouse for development of Alzheimer's like Tau pathology characteristics.
A method of screening a compound for activity in treating an Alzheimer's like Tau pathology, comprising administering said compound to a mouse of claim 12 , and then examining said mouse for the treatment of said Alzheimer's like Tau pathology.
A method of determining if a compound is capable of modulating at least one frontotemporal dementia or Parkinson's-like disease, comprising administering said compound to a mouse of claim 12 , and then examining said mouse for modulation of characteristics of the disease.
A method of determining if a compound is capable of inducing at least one frontotemporal dementia or Parkinson's-like disease, comprising administering said compound to a mouse of claim 12 , and then examining said mouse for development of the disease.
A method for screening a compound for activity in treatment of at least one frontotemporal dementia disease or Parkinson's-like disease, comprising administering said compound to a mouse of claim 12 , and then examining said mouse for the treatment of said disease.
A method of using the mouse of claim 12 to produce a human Tau protein, isoform of the protein, or mutated isoform of the protein, comprising the steps of:
allowing the mouse to produce the protein; and
removing the protein from the mouse.
