Animal models of AD | ||||
Model | Method | Age (month) | Main findings | Reference |
3xTg mice | IHC | 2, 3, 4, 6, 9, and 12 | HH3, a marker of proliferating mitosis, immunoreactivity in SVZ of 3xTg mice was decreased from 3 to 12 months of age in comparison with age-matched control. | Rodriguez et al., 2009 |
3xTg mice | IHC | 11 and 18 | Ki-67+/Mash-1+ cells in SVZ of 3xTg mice were decreased compared with age-matched control. There was no significant differences in the number of Ki-67+ cells between 11 and 18 months old 3xTg mice, but a decreasing trend was observed. |
Hamilton et al., 2010 |
3xTg mice | IHC | 2 | Ki-67+ cells in SVZ of 3xTg mice were reduced than that of wild-type mice. No significant differences in DCX+ cells in SVZ of 3xTg mice compared with wild-type. |
Hamilton et al., 2015 |
5XFAD mice | IHC | 4 | DCX+ cells in SVZ of 5XFAD mice were decreased compared with control. | Park et al., 2016 |
5XFAD mice | IHC | 4 | Nestin+, Ki-67+, and DCX+ cells in SVZ of 5XFAD mice were significantly reduced than that of wild-type. | Liu et al., 2020 |
APP mutant mice | IHC | 11 to 12 | BrdU+ cells in SVZ and cerebral cortex of APP mutant mice were significantly reduced compared with those in control. | Haughey et al., 2002 |
Aβ-injected mice | IHC | 4 | BrdU+ cells in SVZ and cerebral cortex of the Aβ-injected hemisphere were decreased compared with contralateral cortices and vehicle-injected ipsilateral SVZ. | |
Tg2576 mice | IHC | 1.5 | Sox2+-positive neural stem cells were decreased in the SVZ of Tg2576 mice than that of wild-type mice. BrdU+ cells were decreased in the recipient regions of SVZ neurogenesis in Tg2576 mice. |
Scopa et al., 2020 |
APP/PS1 mice | IHC | 3 and 6 | EdU+ cells were decreased in neurospheres from APP/PS1 mice. DCX+ and NeuN+ cells were decreased in RMS of APP/PS1 mice. |
Esteve et al., 2022 |
APP/PS1 mice | IHC | 2 | DCX+ and BrdU+ cells of SVZ were significantly decreased in APPswe/PS1ΔE9 mice compared with wild-type mice. | Demars et al., 2010 |
hTau mice | IHC | 2, 6, and 12 | Ki-67+ cells in SVZ of hTau mice were reduced from 2 months of age. | Komuro et al., 2015 |
ApoE4-KI mice | IHC | 6 to 7 | BrdU+ cells were decreased in the recipient region of SVZ neurogenesis in ApoE4-KI mice. | Li et al., 2009 |
