APOE4 and Microglia Together Drive Alzheimer's Protein Deposits

In healthy brains, immune cells called microglia patrol for damage, clearing away debris and harmful proteins. But in the presence of the APOE4 protein-;the most important genetic risk factor for Alzheimer's disease-;the same cells cause harmful inflammation and clumps of misfolded proteins, according to a new study by scientists at Gladstone Institutes.
