Decoding the Role of an Alzheimer's Causal Gene in Distinct Brain Cell Types
Principal Investigator
Project Goals
We will combine new chimeric human-mouse models with in vitro human neurons and microglia, to unravel the cell type specific contributions of the causal gene, presenilin2 in AD etiopathogenesis.
Project Summary
Mutations in the gene encoding presenilin2 (PSEN2) cause early onset familial Alzheimer’s disease but thus far this was mainly studied in the context of a build-up of toxic amyloid aggregates. However given its restricted localization in degradative compartments, we hypothesize that mechanisms exist leading to disease onset that may differ from its close relative PSEN1. Utilizing new PSEN2 AD mouse models and human neurons/microglia, we will employ functional assays and advanced morphological studies to unravel the cell type specific contributions of PSEN2 in AD etiopathogenesis.
