This strain is a humanized mouse model in which the endogenous mouse Mapt gene has been replaced with its human counterpart, including the 3'UTR region. This model can be utilized to study various neurodegenerative diseases, such as FTD and AD. This model is commonly named htau. In addition, based on the independently developed TurboKnockout fusion BAC recombination technology, Cyagen can also generate hot mutation models based on this strain and provide customized services for specific mutations to meet the experimental needs in pharmacology and other fields.
