Neuroinflammation affects the pathobiology of Alzheimer's disease (AD). Notably, β-amyloid (Aβ) deposition induces microglial activation and the subsequent production of proinflammatory neurotoxic factors. In maintaining brain homeostasis, microglial plasticity also enables phenotypic transition between toxic and trophic activation states. One important(More)
Modulation of the amyloid-β (Aβ) trafficking pathway heralds a new therapeutic frontier for Alzheimer's disease (AD). As CD74 binds to the amyloid-β precursor protein (APP) and can suppresses Aβ processing, we investigated whether recombinant adeno-associated virus (AAV) delivery of CD74 could reduce Aβ production and affect disease outcomes. This idea was(More)
Aberrations in hippocampal neurogenesis are associated with learning and memory, synaptic plasticity and neurodegeneration in Alzheimer's disease (AD). However, the linkage between them, β-amyloidosis and neuroinflammation is not well understood. To this end, we generated a mouse overexpressing familial AD (FAD) mutant human presenilin-1 (PS1) crossed with(More)
