Human stem cell models of Alzheimer’s disease and frontotemporal dementia
UCL Queen Square institute of Neurology
Abstract
The development of human induced pluripotent stem cells (iPSC) and their subsequent differentiation into neurons has provided new opportunities for the generation of physiologically-relevant, in vitro disease models. I will present our work using iPSC to modal familial Alzheimer's Disease (fAD) and Frontotemporal Dementia (FTD). We have investigated the mutation-specific effects of APP and PSEN1 mutations on Abeta generation in neurons generated from individuals with fAD, revealing distinct mechanisms that may contribute to clinical heterogeneity in disease. I will also discuss our work to understand the developmental and pathological changes to tau that occur in iPSC-neurons, particularly the challenges of understanding tau pathology in a developmental system, tau proteostasis and how iPSC-neurons may help us identify early signatures of tau pathology in disease.
