A Large Panel of Isogenic APP and PSEN1 Mutant Human iPSC Neurons Reveals Shared Endosomal Abnormalities Mediated by APP β-CTFs, Not Aβ

Familial Alzheimer’s disease (fAD) results from mutations in the amyloid precursor protein (APP) and presenilin (PSEN1 and PSEN2) genes. Here we leveraged recent advances in induced pluripotent stem cell (iPSC) and CRISPR/Cas9 genome editing technologies to generate a panel of isogenic knockin human iPSC lines carrying APP and/or PSEN1 mutations. Global transcriptomic and translatomic profiling revealed that fAD mutations have overlapping...
