A new study demonstrates how the Alzheimer’s disease-associated *Abi3S212F* genetic variant drives microglial dysfunction and alters amyloid plaque architecture in mouse models. The variant, modeled in mice as *Abi3S212F*, reduced dense-core plaque compaction and selectively lowered dense-core amyloid burden without affecting diffuse or total Aβ, while also triggering microglial loss through apoptosis and pyroptosis. For a neuroscientist completing a PhD at the Brain and Mind Centre, these findings illuminate a critical cell death pathway in microglia that could serve as a novel therapeutic target, directly advancing the mechanistic understanding of neurodegenerative disease.
