Stem Cells Model Genetic Risk for Developing Alzheimer’s Disease

Stem cell study reveals astrocytes carrying the Alzheimer's associated APOE4 gene release more cholesterol than those carrying the APOE3 gene. Findings shed light on how different versions of the APOE gene in astrocytes influence amyloid-beta production and how the oversupply of cholesterol associated with APOE4 astrocytes may promote amyloid-beta formation in Alzheimer's patients.

Differences in Human, Mouse Brain Cells Have Important Implications for Disease Research

A new study reveals humans and mice have significant differences in how oxidative stress and inflammation trigger immune response genes in astrocytes. Researchers suggest lab models of neurodegeneration should incorporate specially engineered mouse models with lower resistance to oxidative stress, rendering them more human-like.
