  • Patent number: 11895993
    Abstract: The present invention provides a disease model animal for tauopathies which reproduces the expression pattern of tau protein isoforms of adult human brain, that is, approximately equal amounts of 3R type tau and 4R type tau being expressed in the adult brain. The method for producing the disease model animal for tauopathies of the present invention comprises the steps of: preparing a tau seeds; and injecting the tau seeds in the brain of an animal carrying a mutation in the tau gene which fails to express the tenth exon. The animal carrying a mutation in the tau gene which fails to express the tenth exon may be produced by using any of the genome editing, gene targeting or base editing technologies.
