N1 - Funding Information:
We would like to express our sincere gratitude to all our coworkers and collaborators, Mari Ohnuki, Megumi Kumazaki, Mitsuyo Kawada, Fumihiko Adachi, Takako Enami, and Misato Funayama for technical assistance; Nobuya Inagaki and Norio Harada for technical advice; and Kazumi Murai for editing the manuscript. This research was funded in part by a grant from the Funding Program for World-Leading Innovative R&D on Science and Technology (FIRST Program) of the Japan Society for the Promotion of Science (JSPS) to S.Y., from the Alzheimer’s Association (IIRG-09-132098) to H.M., from the JST Yamanaka iPS Cell Special Project to S.Y. and H.I., from CREST to H.I., H.M., N.I., and T.T., from a Grant-in-Aid from the Ministry of Health, Labour and Welfare of Japan to H.I., from a Grant-in-Aid for Scientific Research on Innovative Area “Foundation of Synapse and Neurocircuit Pathology” (22110007) from the Ministry of Education, Culture, Sports, Science and Technology of Japan to H.I. and N.I., and from the Japan Research Foundation for Clinical Pharmacology to H.I. H.I. conceived the project; T.K., N.I., M.A., and H.I. designed the experiments; T.K., N.I., M.A., K.W., C.K., R.N., N.E., N.Y. and K. Tsukita performed the experiments; T.K., N.I., M.A., and H.I. analyzed the data; K.O., I.A., K.M., T.N., K.I., W.L.K., O.H., S.H., and T.C. contributed reagents, materials and analysis tools; Y.K., Y.O., Y.S., M.N., K.Y., S.Y., S.S., T.A., R.H., and S.U. recruited the patients; R.T., H.M., and S.Y. provided critical reading and scientific discussions; T.S., K.K., T.T., and K. Takahashi performed microarray analysis; T.A. performed karyotyping; A.W. performed bisulfite genomic sequencing; K.I. and D.W. performed electrophysiology; K. Tsukita, T.K., and H.H. produced the lentivirus; H.I., N.I., M.A., and T.K. wrote the paper. The experimental protocols dealing with human or animal subjects were approved by the institutional review board at each institute. S.Y. is a member without salary of the scientific advisory boards of iPierian, iPS Academia Japan, Megakaryon Corporation, and Retina Institute Japan.

N2 - Oligomeric forms of amyloid-β peptide (Aβ) are thought to play a pivotal role in the pathogenesis of Alzheimer's disease (AD), but the mechanism involved is still unclear. Here, we generated induced pluripotent stem cells (iPSCs) from familial and sporadic AD patients and differentiated them into neural cells. Aβ oligomers accumulated in iPSC-derived neurons and astrocytes in cells from patients with a familial amyloid precursor protein (APP)-E693Δ mutation and sporadic AD, leading to endoplasmic reticulum (ER) and oxidative stress. The accumulated Aβ oligomers were not proteolytically resistant, and docosahexaenoic acid (DHA) treatment alleviated the stress responses in the AD neural cells. Differential manifestation of ER stress and DHA responsiveness may help explain variable clinical results obtained with the use of DHA treatment and suggests that DHA may in fact be effective for a subset of patients. It also illustrates how patient-specific iPSCs can be useful for analyzing AD pathogenesis and evaluating drugs.
