Summary:

iPSC-derived lines from 53 individuals with genetic risk for Alzheimer's disease were generated and evaluated.  Additionally, data collection for each patient included genomic sequencing, longitudinal cognitive scores and quantitative neuropathology.  Using these evaluations the authors were able to reveal significant associations between specific Aβ and tau species and the levels of plaque and tangle deposition in the brain and, more importantly, with the trajectory of cognitive decline.  This data presented establishes this iPSC collection as a resource to understand molecular pathways underlying AD.
