(Submitter supplied) Our understanding of Alzheimer’s disease (AD) pathogenesis is currently limited by difficulties in obtaining live neurons from patients and the inability to model the sporadic form of AD. It may be possible to overcome these challenges by reprogramming primary cells from patients into induced pluripotent stem cells (iPSCs). We reprogrammed primary fibroblasts from two patients with familial AD (both caused by a duplication of APP1, APPDp), two with sporadic AD (sAD1, 2) and two non-demented control individuals (NDCs) into iPSC lines. more...

(Submitter supplied) To investigate gene expression changes related to two fAD mutations (A79V and L150P) in the Presenilin-1 gene (PSEN1) we compared the transcriptomes (polyA and total) of glutamatergic cortical neurons derived from fAD-mutant human induced pluripotent stem cells and their individual isogenic controls generated via precision CRISPR/Cas9 genome editing.

(Submitter supplied) Early-onset Alzheimer’s disease-like pathology in Down syndrome (DS, trisomy 21) is commonly attributed to an increased dosage of the amyloid precursor protein (APP) gene. To test this central tenet of the amyloid-cascade hypothesis we deleted the supernumerary copy of the APP gene in trisomic DS iPSC, or upregulated APP expression in euploid human pluripotent stem cell lines with dCas9-VP64, and subjected these lines to prolonged cortical neural differentiation. more...

(Submitter supplied) Loss of the Sortilin-related receptor 1 (SORL1) gene seems to act as a causal event for Alzheimer’s disease (AD). Recent studies have established that loss of SORL1, as well as mutations in autosomal dominant AD genes APP and PSEN1/2, pathogenically converge by swelling early endosomes, AD’s cytopathological hallmark. Acting together with the retromer trafficking complex, SORL1 has been shown to regulate the recycling of the amyloid precursor protein (APP) out of the endosome, contributing to endosomal swelling and to APP misprocessing. more...

(Submitter supplied) The apolipoprotein E4 (APOE4) variant is the single greatest genetic risk factor for sporadic Alzheimer's disease (sAD). However, the cell-type-specific functions of APOE4 in relation to AD pathology remain understudied. Here, we utilize CRISPR/Cas9 and induced pluripotent stem cells (iPSCs) to examine APOE4 effects on human brain cell types. Transcriptional profiling identified hundreds of differentially expressed genes in each cell type, with the most affected involving synaptic function (neurons), lipid metabolism (astrocytes), and immune response (microglia-like cells). more...

(Submitter supplied) PSEN1 ΔE9 mutation causes a familial form of Alzheimer's disease. We have previously shown that human induced pluripotent stem cell (iPSC)-derived astrocytes carrying PSEN1 ΔE9 mutation exhibit transcriptional and functional abnormalities (Stem Cell Reports. 2017;9:1885-1897). Here we injected glial progenitors derived from 2 pairs of PSEN1 ΔE9 mutant- isogenic CTRL iPSCs intracerebroventricularly into newborn mice. more...

(Submitter supplied) The dysregulation of gene dosage due to duplication or haploinsufficiency is a major cause of autosomal dominant diseases such as Alzheimer’s disease. However, there is no rapid and efficient method for manipulating gene dosage in a human model system such as human induced pluripotent stem cells (iPSCs). Here, we describe a simple and precise method to simultaneously generate iPSC lines with different gene dosages using paired Cas9 nickases. more...

(Submitter supplied) We generated ELAVL4 knockout (KO), overexpression (OE), and rescue human induced pluripotent stem cell-derived neurons to study the effect that ELAVL4 has on AD-related cellular phenotypes. To gain insight into the molecular cascades involved in neuronal ELAVL4 signaling, we then performed gene expression profiling analysis using data obtained from RNA-seq using triplicate samples for each condition

(Submitter supplied) While amyloid-β (Aβ) plaques are considered a hallmark of Alzheimer's disease, clinical trials focused on targeting gamma secretase, an enzyme involved in aberrant Aβ peptide production, have not led to amelioration of AD symptoms or synaptic dysregulation. Screening strategies based on mechanistic, multi-omics approaches that go beyond pathological readouts can aid in the evaluation of therapeutics. more...

(Submitter supplied) Background: Widescale evidence points to the involvement of glia and immune pathways in the progression of Alzheimer’s disease (AD). AD-associated iPSC-derived glial cells show a diverse range of AD-related phenotypic states encompassing cytokine/chemokine release, phagocytosis and morphological profiles, but to date studies are limited to cells derived from PSEN1, APOE and APP mutations or sporadic patients. more...
