The blood-brain barrier (BBB) presents a barrier for circulating factors, but simultaneously challenges drug delivery. How the BBB is altered in Alzheimer disease (AD) is not fully understood. To facilitate this analysis, we derived brain endothelial cells (iBECs) from human induced pluripotent stem cells (hiPSCs) of several patients carrying the familial AD PSEN1 mutation. We demonstrate that, compared with isogenic PSEN1 corrected and control iBECs, AD-iBECs exhibit altered tight and adherens junction protein expression as well as efflux properties. Furthermore, by applying focused ultrasound (FUS) that transiently opens the BBB and achieves multiple therapeutic effects in AD mouse models,..View full abstract
