Transgenic Animal Models

With the discovery of AD-related genes, scientists have created a large number of transgenic animals mimicking hallmarks in human AD through introducing genetic modification of gene of interest. This gene editing approach facilitated AD-related pathological mechanism or screen drugs studies. Mice are most commonly used organism for AD considering they are relatively lower in cost, shorter in life span and easier to manipulate in gene editing. In addition, rats and nonmammalian species such as zebrafish and nematodes can also be used as AD model animals.

Study examples

Strategy used to develop 3×Tg-AD mice. Figure 1. Strategy used to develop 3×Tg-AD mice. Using the pronuclear microinjection technique, we coinjected two independent transgene constructs encoding human APPSwe and tauP301L (4R/0N), both under the control of the mouse Thy1.2 regulatory elements, into single-cell embryos harvested from mutant homozygous PS1M146V knockin mice. The entire mouse Thy1.2 genomic sequence is shown with exons depicted as boxes and noncoding sequences as thin lines. The injected embryos were reimplanted into foster mothers and the resulting offspring genotyped to identify 3×Tg-AD mice.
