Immune Activation in Alzheimer Disease

We describe how brain-resident macrophages, the microglia, are able to detect Aβ species and be activated, as well as the consequences of activated microglia in AD pathogenesis. We discuss transcriptional changes of microglia in AD, their unique heterogeneity in humans, and emerging strategies to study human microglia. Finally, we expose, beyond Aβ and microglia, the role of peripheral signals and different cell types in immune activation.
