iPSC modeled Alzheimer’s disease.
| Reference | Disease and mutation | Tested cells (induced from iPSC) | Phenotype reported | Effective drug treatment |
|---|---|---|---|---|
| Yagi et al., 2011 | fAD: PS1 A246E mutation, PS2 N141I mutation | Neurons | Elevated Aβ42/Aβ40. | Compound E (γ-secretase inhibitor) and compound W (Aβ42 inhibitor) reduced Aβ42 and Aβ40. High dose compound W reduced Aβ42/Aβ40 ratio. |
| Israel et al., 2012 | fAD: duplication of APP sAD | Neurons | Aβ(1-40), phospho-tau, aGSK-3β increase, large RAB5-positive early endosomes. | β-secretase inhibitor reduces phospho-tau and aGSK-3β. |
| Koch et al., 2012 | fAD: PS1 L166P mutation, PS1 D385N mutation | iPSC and embryonic derived NSCs | Elevated Aβ42/Aβ40. Decreased Aβ40, while Aβ42 did not differ from control. Partial loss of γ-secretase function. | γ-secretase inhibitor and non-steroidal anti-inflammatory drugs reduce Aβ. |
| Duan et al., 2014 | sAD: ApoE3/E4 | Basal forebrain cholinergic neurons | Elevated Aβ42/Aβ40. Elevated sensitivity to calcium influx and glutamate toxicity. | Low dose of γ-secretase inhibitor elevates Aβ secretion in sAD, while it typically reduces Aβ in fAD. |
| Kondo et al., 2013 | fAD: APP-E693Δ mutation and APP-V717L mutationsAD | Neurons | Intracellular Aβ aggregation in APP-E693Δ line, while no significant extracellular plaque aggregation was observed. Endoplasmic reticulum and oxidative stress response in APP-E693Δ line. | Docosahexaenoic acid (DHA) reduces stress response in APP-E693Δ and one of two sporadic patients. |
| Muratore et al., 2014 | fAD: APP-V717L mutation | Neurons | Elevated Aβ42 and Aβ38. Increased β-secretase cleavage of APP. Altered γ-secretase cleavage site Hyperphosphorylated tau. | Aβ-specific antibody reduce elevated tau. |
| Sproul et al., 2014 | fAD: PS1 A246E mutation, PS1 M146L mutation | Neural progenitor cells, neurons | Elevated Aβ42/Aβ40, more apparent in NPCs than neurons. 14 genes (e.g., NLRP2, ASB9, NDP) are recognized to alter expression in PS1 mutated patients’ NPCs, 5 of them involved in late-onset AD as well. | |
| Hossini et al., 2015 | sAD | Neurons | Elevated GSK3β activity and phosphorylated tau. Generate an AD-related protein network. Ubiquitin-proteasome system function is down-regulated in sAD. | γ-secretase inhibitor down regulates phosphorylated tau. |
| Moore et al., 2015 | fAD: PS1 Y115C mutation, PS1 intron 4 mutation, APP V717I mutation, APP duplication | Neurons | All lines demonstrated increased Aβ42 generation. APP mutations show elevated phenotype while PS1 mutations did not. | γ-secretase inhibitor increased intracellular tau, β-secretase inhibitor reduced intracellular tau. γ-secretase modulation reduced intracellular tau. |
| Young et al., 2015 | sAD: SORL1 SNPs (risk variants and Protective variants) | Neurons | BDNF treatment reduces Aβ by SORL1–dependent upregulation in protective homozygotes or heterozygotes. In risk homozygotes, BDNF treatment is not effective in reducing Aβ. Overexpression of SORL1 cDNA ameliorates Aβ. | |
| Woodruff et al., 2016 | fAD: PS1 ΔE9 mutation, APP V717F mutation, APP Swedish mutation | Neurons | APP and LDL endocytosis and soma-to-axon transcytosis of lipoproteins dysfunction in fAD. | β-secretase inhibitor recovers endocytosis function. |
| Jones et al., 2017 | fAD and sAD | Astrocytes Neural progenitor cells | Atrophy and abnormal localization of astrocytes from both fAD and sAD, while NPCs did not show evident pathology. |
